Amphibolips oaxacae Nieves-Aldrey & Pascual Amphibolips oaxacae Nieves-Aldrey & Pascual, 2012. In Nieves-Aldrey et al.2012: 14–16. Material examined. HOLOTYPE. ♀ deposited in MNCN (Cat. nº 2249; Code: 89204). MEXICO, Oaxaca, S. Pe-dro Tapanatepec, 16º 22’ 34.40” N, 94º 04’ 43 11” W, 1300 masl; Ex gall Quercus sp. aff. sapotifolia, (29.iii.2006) iii.2006, leg. E. Pascual. Diagnosis. This species is characterized by completely infuscate forewing, with anterior infuscate band, including costal and proximal half of anal cells, radial cell uniformly infuscate (Fig. 13F); scutellar posterior depression deep, almost as broad as scutellar foveae (Fig. 11I). Besides the distinctive forewing pattern, adults closely resemble A. tarasco by less densely rugate mesoscutum in posteromedian margin. These species can be differentiated by their mesoscutellum: scutellar foveae ovate, median carina complete in A. oaxacae (foveae triangular with median carina reduced to anterior half of foveae and the rest is rugate in A. tarasco), posteromedian depression almost as broad as total width of foveae (around half of total width of foveae in A. tarasco) (Figs 11 I–J). The globular gall resembles others but galls of A. oaxacae and A. tarasco are hard, around 40 mm in diameter, not deformable at finger pressure, with mottled surface. Both species cannot be differentiated by galls shape, only by the host plant: A. oaxacae galls on Quercus sp. aff. s apotifolia, A. tarasco galls on Q. castanea. Gall. A subglobose large bud gall, maximum 40 mm in diameter, outer shell thin, resistant, slightly lignified. Pale green with darker green spots when fresh and turning brown when dry. The gall is monolocular, with a spongy internal tissue, filling in the entire gall; the larval cell is rounded (Nieves-Aldrey et al. 2012: Fig. 18F). Host. Quercus sp. aff. sapotifolia (according to original description). Biology. Only females are known. The galls were collected in March; adults emerged in the same month. Distribution. Mexico: Oaxaca State. Remarks. Most closely resembles A. tarasco. Only one specimen of A. oaxacae is known and until more material is found it is impossible to sort out the intraspecific variability in this species. However, the actual differences that determine A. oaxacae are robust enough to consider it as a valid species., Published as part of Cuesta-Porta, Víctor, Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Cibrián-Tovar, David, Barrera-Ruíz, Uriel M., Silva, Salvador Ordaz, Sánchez, Imelda Virginia López, Melika, George & Pujade-Villar, Juli, 2020, Revision of the Amphibolips species of the ' nassa' complex from Mexico and central America (Hymenoptera: Cynipidae), pp. 1-50 in Zootaxa 4877 (1) on page 23, DOI: 10.11646/zootaxa.4877.1.1, http://zenodo.org/record/4567340, {"references":["Nieves-Aldrey, J.

Paratypes (deposited in MNCN): 2♂, “ Nevado Colima, 2370 m, Ex Q. candicans, (31.iii.2009) iv.2009, leg. E. Pascual ” (Codes: 89218–89219). Aditional material. Deposited in UB with the following labels: “S066; S068, MEXICO, Monte Escobedo, Montes Escobedo, Zacatecas, (21.vii.2011) only galls, Ex Q. calophylla ”; “S243, MEXICO, Propiedad la Victoria, Barrio la Tlazintla, Acaxochitlán, Hidalgo, (07.vi.2010) only galls, Ex Quercus sp.”. Diagnosis. This species is characterized by faintly infuscate forewings, with anterior infuscate band in females (male forewing completely infuscate with darker anterior band); lateral margin of eye with a smooth band usually emarginate by a carina; metasoma tergum II before band of micropunctures almost completely coarsely coriaceous, with some fine irregular longitudinal striae. Closely resembles A. jaliscensis (see diagnosis to A. jaliscensis). Also closely resembles A. rulli n. sp. but differs in the sculpture of metasoma tergum II, which is coriaceous in front of the micropuncture band in A. nevadensis (smooth in front of micropunctures in A. rulli n. sp.). Galls are very similar to those of A. nassa and A. rulli n. sp.; these species cannot be differentiated by galls, only by the host plant; Amphibolips nevadensis on Q. calophylla, A. nassa on Q. castanea and A. rulli n. sp. on Q. eduardi and Q. viminea. All these galls are subglobose, very hard and fusiform at apex, ending in a defined tip. Gall. A subspherical bud gall, fusiform at apex, ending in a tip, maximum 40 mm in diameter, outer shell thin, resistant, slightly lignified. Olive green with pale green spots when fresh and turning dark green when dry. The gall is monolocular, with a spongy internal tissue, filling the entire gall. The larval cell is rounded. Pictures of the gall are provided in Nieves-Aldrey et al. (2012: Figs 19E–F) Host. According to the original description, Q. calophylla (= candicans). We found galls on the same host plant. Biology. Only females are known. The galls were collected in March; adults emerged in the same month. Distribution. Mexico: Jalisco State. Remarks. Nieves-Aldrey et al. (2012) confused the figure of the mesosoma (dorsal view) of the male of A. nevadensis with that of a female of A. oaxacae (Nieves-Aldrey et al. 2012: Fig. 7B).

Equihua ���. Diagnosis. This species is characterized by its clear forewings with only one heavily infuscate patch at the base of the radial cell (Fig. 13A); broad and complete notauli delimited by an internal carina on posterior half of mesoscutum (Fig. 12A); mesoscutellar posterior emargination shallow, only slightly emarginate. This species most closely resembles A. kinseyi n. sp. but differs by a complete notauli (incomplete in A. kinesyi n. sp.); upper face coarsely reticulate-rugose (alutaceous in A. kinseyi n. sp.); speculum glabrous and finely rugate (sparsely pubescent and transversally carinated in A. kinseyi n. sp.); metasomal tergum II with fine, almost inconspicuous, micropunctures on posterior 1/3 (posterior 1/3 metasomal tergum II conspicuously micropunctate in A. kinseyi n. sp.). The forewing pattern also resembles A. quercuspomiformis comb. nov., but the tarsal claws with an acute basal lobe in A. aliciae (simple in A. quercuspomiformis comb. nov.); and the notauli are complete, shallow, and not delimited by carinae in A. quercuspomiformis comb. nov. Galls of A. aliciae are fusiform, fragile onto smallest pressure, internal hollowlike space with thin filaments radiating from the central larval chamber (Figs 14B, 14D); while galls of A. kinseyi n. sp. and A. quercuspomiformis comb. nov. are subglobose, hard, with internal space obliterated by a spongious parenchyma. The internal structure of A. aliciae gall also resembles the gall of A. salicifoliae, which are hollow with radiating filaments. However, they can be differentiating by the shape and gall location: fusiform galls on buds in A. aliciae and spherical galls on leaves in A. salicifoliae. Gall (Figs 14 A���D). A fusiform bud gall with a fine tip and base, with a hard, lignified outer shell, 2.5 mm long. Internal space hollow with thin filaments radiating from the central larval chamber, 5���6 mm in diameter. Hosts. Quercus salicifolia (Panama); Q. crassifolia (Mexico, new record). Biology. Only the sexual generation is known. Galls were collected from January to March; adults emerged shortly after gall collecting. Distribution.

HOLOTYPE. ♀ (deposited in AMNH) with the following labels: “ MEXICO, Ciudad de Mexico, Ciudad de Mexico ” (white label), “ Q. crassipes, (01.xii.1932) leg. Kinsey ” (white label); Holotype Amphibolips kinseyi Cuesta-Porta & JP-V n. sp., desig. Cuesta-Porta, 2020” (red label). Etymology. Named in honor of Alfred C. Kinsey (1894–1956) who greatly contributed to the knowledge of Amphibolips and the American cynipid fauna. Diagnosis. The new species is characterized by incomplete notauli margined dorsally by carinae on posterior half of mesoscutum; mesoscutellum margined laterally by strong carina that emarginate posterior depression of mesoscutellum, both laterally and posteriorly. Most closely resembles A. aliciae by the forewing colouration, notauli emarginate by carina on dorsal side. It differentiate by brown to chestnut head and mesosoma, ambarine metasoma (head and mesosoma black, metasoma rufous in A. aliciae), strongly emarginated mesoscutellum laterally and posteriorly (not emarginate in A. aliciae); frons alutaceous with fine rugae (coarsely reticulate-rugose in A. aliciae). Forewing colouration also resembles those of A. salicifoliae and A. quercuspomiformis comb. nov., but in A. kinseyi n. sp. infuscate area on basal margin of radial cell larger, tarsal claws with basal lobe (claws simple in A. salicifoliae and A. quercuspomiformis comb. nov.). Furthermore, bud galls of the new species are ovate with lignified parenchyma while galls of A. aliciae are fragile, fusiform, internal hollow with radiating filaments supporting the larval chamber. The gall is similar to other species with a large globular shape without mottled surface and not deformable at finger pressure (as A. quercuspomiformis comb. nov. and A. bassae n. sp.), but the size is smaller, around 20 mm in diameter.

Amphibolips nassa closely resembles A. zacatecaensis but differs in scutellar foveae almost smooth and undivided, without transversal carinae in A. nassa (with strong median carina and transversal carinae in A. zacatecaensis); posteromedian depression projected anteriorly, reaching posterior margin of foveae, deep on posterior edge (depression shallow not projected to anterior margin in A. zacatecaensis); posterolateral margins ended in small tips (completely rounded in A. zacatecaensis); metasomal tergum II with posterior coriaceous sculpture before band of micropunctures (completely smooth in A. zacatecaensis); and galls (A. nassa are subglobose, but a bit fusiform with a tip and a base, with lignified spongious parenchyma while in A. zacatecaensis galls are fragile, globose with a tiny tip at apex, with soft spongious parenchyma. The galls are very similar to A. nevadensis and A. rulli n. sp.; galls of these species cannot be differentiated, only by the uniformly brown surface of the galls of A. nassa (mottled in A. nevadensis and A. rulli n. sp.), and the host plants are different; Amphibolips nassa in buds of Q. castanea, A. nevadensis galls on Q. calophylla and A. rulli n. sp. on Q. eduardi and Q. viminea. All these galls are subglobose, hard and with an apical tip, resulting from the longitudinal elongation of the gall. Gall (Figs 15 F–G). A rather large, subglobose, slightly fusiform, elongated bud oak apple, up to 48 mm in diameter, detachable, with a fine tip and base; with hard, lignified parenchyma. Larval chamber central or near the base of the gall, on buds. Host. According to the original description, Q. castanea. Biology. Galls were collected in December; the only known adult was dissected out of the gall. Distribution. Mexico: Michoacán state. Remarks. Kinsey (1937) mentioned that similar galls were collected in the same place on Q. mexicana by Morelia from the same host plant as the holotype, but after knowing that different species are found in similar galls, we cannot assure this citation was correct., Published as part of Cuesta-Porta, Víctor, Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Cibrián-Tovar, David, Barrera-Ruíz, Uriel M., Silva, Salvador Ordaz, Sánchez, Imelda Virginia López, Melika, George & Pujade-Villar, Juli, 2020, Revision of the Amphibolips species of the ' nassa' complex from Mexico and central America (Hymenoptera: Cynipidae), pp. 1-50 in Zootaxa 4877 (1) on page 22, DOI: 10.11646/zootaxa.4877.1.1, http://zenodo.org/record/4567340, {"references":["Kinsey, A.

This species is characterized by smooth scutellar foveae with a strong median carina completely dividing the foveae (Fig. 11F); posteromedian depression interrupted by transversal carina (Fig. 5D, posterior view), depression not reaches posterior margin of mesoscutellum. Closely resembles A. jaliscensis (see diagnosis to A. jaliscensis). The large globular gall is similar to other species, with or without mottled surface (Nieves-Aldrey et al. 2012: Figs 20A–B); impossible to differentiate from A. hidalgoensis and A. jaliscensis but differs from A. quercuspomiformis comb. nov., A. oaxacae, A. tarasco, A. kinseyi n. sp. and A. bassae n. sp. by the deformable surface at finger pressure because of the relatively soft parenchyma in A. hidalgoensis, A. jaliscensis and A. michoacaensis. Gall. A subglobose large bud gall, up to 48 mm in diameter, outer shell thin but resistant, uniformly pale green, turning into brown when dry. The gall is monolocular, with a spongy internal tissue, filling the entire gall. The larval cell is rounded (Nieves-Aldrey et al. 2012: Figs 20A–B). Host. Quercus castanea, Q. emoryi. Biology. Only the sexual generation is known. Galls were collected between April and May; adults emerged between May and October of the same year of collection. Distribution. Mexico: Michoacan and Zacatecas states. Remarks. Nieves-Aldrey et al. (2012) described the males with 12 flagellomeres, however, the antenna has 13 flagellomeres (type specimens examined). This species shares several characters with A. jaliscensis, including the forewing pattern, that were originally used as diagnostic (Nieves-Aldrey et al. 2012), and the gall morphology is also similar between the two species (see corresponding remarks under A. jaliscenis)., Published as part of Cuesta-Porta, Víctor, Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Cibrián-Tovar, David, Barrera-Ruíz, Uriel M., Silva, Salvador Ordaz, Sánchez, Imelda Virginia López, Melika, George & Pujade-Villar, Juli, 2020, Revision of the Amphibolips species of the ' nassa' complex from Mexico and central America (Hymenoptera: Cynipidae), pp. 1-50 in Zootaxa 4877 (1) on page 20, DOI: 10.11646/zootaxa.4877.1.1, http://zenodo.org/record/4567340, {"references":["Nieves-Aldrey, J.

Hosts. Quercus affinis. Biology. Only females are known. The mature galls were collected in late June; adults emerged in early July. Distribution. Mexico: Hidalgo State. Remarks. The gall of this new species is not usual for Mexican Amphibolips species, but two North American species have similar galls on the underside of leaves: A. quercusracemaria (Ashmead, 1881) from Florida (USA) on Q. laurifolia and A. nubilipennis (Harris, 1841) from Massachusetts on several species of red oaks. Nevertheless, the sculpture of the mesoscutum and the colour pattern of wings are different in A. quercusracemaria and A. nubilipennis.

Etymology. Named in honor of Josep Rull i Andreu. Diagnosis. The new species is characterized by the dorsal projection, which is situated towards the anterior margin of the area of punctured sculpture on tergum II, never reaching half of the tergal length; smooth area bordering lateral margin of compound eye, usually posterodorsally limited by a carina; F1 1.6x as long as F2. Most closely resembles A. nevadensis but can be differentiated by the female metasomal tergum II, which is mainly polished, smooth with faint coriaceous sculpture bordering posterior punctures in the new species (metasomal tergum II completely coriaceous except for posterior band of micropunctures in A. nevadensis). Galls of both species are subglobose, elongate to an apical tip, with hard outer shell and mottled surface. Amphibolips nassa has similar galls but the adults strongly differ by the forewing colour pattern, degree of radial cell infuscatation: veins visible through infuscation in the new species (radial cell highly infuscate, hidden veins in A. nassa); scutellar foveae with transverse rugae, distinctly divided medially in the new species (notaular furrow smooth and scutellar foveae indistinctly separated medially in A. nassa). These species cannot be differentiated by galls, only by the host plant; Amphibolips nassa on Q. castanea, A. nevadensis on Q. calophylla and A. rulli n. sp. on Q. eduardi, Q. viminea. Description.

PANAMA, Chiriquí, Volcan Baru 8º 47’ 50 8” N, 82º 29’ 35 9” W, 1800–2070m, Ex Q. salicifolia, (27.i.2009) ii.09, leg. E. Medianero. Paratypes: 2♂ & 2♀ with same data as the holotype (two paratypes deposited in MNCN, and two paratypes MEUP). Diagnosis. This species is characterized by the almost hyaline forewings in males and females, tarsal claws simple and notauli incomplete, short, distinct, with base of notaular groove smooth. This species closely resembles A. quercuspomiformis comb. nov. with which it shares the following character states: simple tarsal claws; mesoscutellum posteriorly not emarginated; speculum smooth and glabrous. Differs by the forewing colouration which is almost completely hyaline, slightly infuscate in A. salicifoliae (hyaline with dark patch at the base of radial cell in A. quercuspomiformis comb. nov.); notauli incomplete, broad, smooth, visible in posterior third of mesoscutum in A. salicifoliae (notauli complete, shallow, and partially covered by the sculpture of mesoscutum, furrow rugose in A. quercuspomiformis comb. nov.); median propodeal area shining, smooth in A. salicifoliae (dull rugose in A. quercuspomiformis comb. nov.); metasomal terga smooth without micropunctures in A. salicifoliae (posterior third of metasomal tergum II and subsequent tergum with micropunctures in A. quercuspomiformis comb. nov.). Galls of A. salicifoliae are subglobose, on the underside of leaves, very fragile, outer shell thin, hollow internally with thin filaments radiating from larval chamber while galls of A. quercuspomiformis comb. nov. are on buds, with outer shell hard, internal parenchyma spongious. Thin filaments radiating from the larval chamber to the outer shell in A. aliciae. We can differentiate these galls by the shape of the gall and its location (fusiform bud galls in A. aliciae and spherical leaf galls in A. salicifoliae) Host. Quercus salicifolia. Gall. Globose and fragile galls on the underside of leaves, with maximum diameter 30 mm; outer shell thin, internal space hollow with filaments radiating from the larval chamber. Larval chamber central or at the base of the gall (Medianero & Nieves-Aldrey 2010: Figs 8 G–H). Biology. The sexual generation is only known. Galls were collected in January; adults emerged in February. Distribution. Panama.

The cynipid gall wasp species of Amphibolips (Cynipidae: Cynipini) belonging to the “nassa” complex are reviewed for Mexico and Central America. Five new species are described: A. bassae Cuesta-Porta & Pujade-Villar n. sp., A. bromus Pujade-Villar & Cuesta-Porta n. sp., A. kinseyi Cuesta-Porta & Pujade-Villar n. sp., A. rulli Pujade-Villar & Cuesta-Porta n. sp., and A. turulli Pujade-Villar & Cuesta-Porta n. sp. Amphibolips quercuspomiformis (Bassett) comb. nov. is redescribed and Amphibolips malinche Nieves-Aldrey & Maldonado is proposed as a new synonym of A. hidalgoensis Pujade-Villar & Melika. The validity of A. dampfi is discussed. Diagnostic characters, distribution, host-plant relationships, and biology are provided. Also new diagnostic characters and new distribution data for earlier described species are given. Keys to adults and galls for all known “nassa” complex species from Mexico and Central America are presented.

Additional material. MEX-298, MEXICO, Predio La Victoria, Acocaxoithlan, Hidalgo Ex. Q. affinis, (19. iii.2014) 7–21.iv.2014: 7♂ (UB), leg. J. Pujade-Villar & D. Cibrian-Tovar. Diagnosis. This species is characterized for a deep V-shaped posteromedian depression on the mesoscutellum which is reaching the posterior margin of scutellar foveae; strong horn-like posterolateral projections slightly bent upwards (Figs 12B, 12 G–H). Area laterad to parapsidal lines rugose. Forewing (Fig. 13C) heavily infuscate with clear cross band extended from the anteromedian margin of radial cell to the posterior area, into second cubital and discoidal cells, not reaching posterior margin. This species highly resembles A. turulli n. sp. (see below) especially for the similar mesoscutellum and forewing colour pattern; but in A. dampfi the area laterad to parapsidal lines rugose (alutaceous in A. turulli n. sp.); forewings with anal and basal half of discoidal cells completely infuscate (hyaline in A. turulli n. sp.), fragile subglobose internally spongious bud galls slightly pedunculate and with small tip at apex with internal spongious tissue soft, mainly white turning into roseate around larval cell, light brown when dry (turgescent green leaf galls in A. turulli n. sp.). The gall of A. dampfi is unmistakable. It is very deformable for its lax and soft spongy internal tissue with a cotton-like appearance. It resembles A. zacatecaensis gall but in A. dampfi the internal tissue is white to rosy near the larval chamber, very soft, cotton-like (light brown and denser in A. zacatecaensis). Gall (Fig. 15E). Monolocular subglobose bud gall, up to 50 mm in diameter, with slightly elongate apex and base with smooth and fragile surface, homogenous in colour; internal spongious tissue soft, white to rosy, turning brown when dry; with cotton-like texture (the fibers leaving numerous aerial interspaces); larval chamber occupying central part of the gall, about 4–5 mm in diameter, embedded with spongious tissue. Hosts. Quercus ocoteifolia, Q. affinis. Biology. Only the sexual generation is known. Galls mature by February and March; adults emerge from February to April. Distribution. Mexico: Hidalgo and Oaxaca states. Remarks. The name of the host plant (Q. ocoteifolia), cited in the original description of this species, was erroneously written as Q. ocoteaefolia. This incorrectly spelled epithet appeared in a number of infraspecific descriptions: Quercus ocoteaeifolia f. confusa Trel., Q. laurina var. ocoteaefolia (Liebm.) Wenz., and Q. nitens var. ocoteaefolia (Liebm.) A. DC. All those forms and varieties were synonymized under Q. ocoteifolia. Comments. According to Melika et al. (2011) A. dampfi closely resembles A. palmeri Basset 1890 and may be synonymous. The type of A. palmeri (a single female) is lost, nevertheless the adult and gall descriptions seem to be consistent with this hypothesis (see A. palmeri below). The type of A. dampfi is also presumed to be lost (C. Le Beau pers. comm.)., Published as part of Cuesta-Porta, Víctor, Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Cibrián-Tovar, David, Barrera-Ruíz, Uriel M., Silva, Salvador Ordaz, Sánchez, Imelda Virginia López, Melika, George & Pujade-Villar, Juli, 2020, Revision of the Amphibolips species of the ' nassa' complex from Mexico and central America (Hymenoptera: Cynipidae), pp. 1-50 in Zootaxa 4877 (1) on pages 12-13, DOI: 10.11646/zootaxa.4877.1.1, http://zenodo.org/record/4567340, {"references":["Kinsey, A.

This species is characterized by lightly infuscate forewings with anterior infuscate band in females (males with completely infuscate forewings with a deeper infuscate anterior band), radial cell with a clear area on distal third in both males and females; lateral margin of eye smooth. Most closely resembles A. michoacaensis but scutellar foveae transversally carinate, with fine median carina not reaching anterior margin (smooth foveae with coarse median carina reaching anterior margin in A. michoacaensis); scutellar posteromedian depression reaching margin of metascutellum (depression interrupted before posterior margin by strong transversal carina in A. michoacaensis) (Figs 5D, 11 E–F; 12C–D). This species is also morphologically close to A. nevadensis by the forewing pattern and smooth lateral margin of eye, but can be differentiated in females by F1 1.4x as long as F2 (1.6x longer in A. nevadensis), posterior band of micropunctures on metasoma tergum II dorsally narrower, covering posterior 1/3 of tergum laterally and reduced to posterior 1/5 dorsally (uniform in posterior 1/ 3 in A. nevadensis); males scutellar median depression rugate as rest of mesoscutellum (median depression with few rugae, mostly smooth in A. nevadensis). Galls of A. jaliscensis and A. michoacaensis are subglobose, outer shell thin and rather fragile with uniform colouration (pale green in A. jaliscensis and whitish in A. michoacaensis), with spongious parenchyma internally, the gall turning brown when dry. Galls of A. nevadensis are different for its distinct apical tip. Amphibolips jaliscensis gall is similar to other species with large globular shape, without mottled surface; it is not differentiable from A. hidalgoensis and A. michoacaensis, but differs from A. quercuspomiformis comb. nov., A. oaxacae, A. tarasco, A. kinseyi n. sp. and A. bassae n. sp. in having a deformable surface at finger pressure because the parenchyma relatively soft in A. hidalgoensis, A. jaliscensis and A. michoacaensis. Gall. Spherical bud galls, maximum diameter 43–54 mm; outer shell thin, firm, surface smooth with uniform pale green colour turning into brown when dry; internal tissue soft and spongious, with central larval chamber around 5 mm (Nieves-Aldrey et al. 2012: Figs 19A–B). Hosts. Quercus aff. calophylla (= Q. aff. candicans), Q. laurina. Biology. The sexual generation is only known. The mature galls were collected in late March; adults emerged in April and May. Distribution. Mexico: Jalisco and Mexico states. Remarks. Nieves-Aldrey et al. (2012) characterized this species mainly by its clear, less infuscate area on apical third of radial cell of the forewing. This character has also been observed in A. hidalgoensis and A. michoacaensis, thus it is no longer considered as an exclusive diagnostic character for A. jaliscensis. We provide alternative characters to determine A. jaliscensis (see diagnosis). This species is difficult to differentiate from A. michoacaensis, except for two scutellar characters. This fact leads us to suspect that they might be the same species. The transversal carinae of the scutellar foveae are variable in length, number and impression between specimens of this genus. The currently known specimens of these two species appear to be consistent with regards to possession of the characters proposed in this study to differentiate them, albeit more material is needed to assess the degree of intraspecific variability, and to confirm which are reliable diagnostic characters., Published as part of Cuesta-Porta, Víctor, Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Cibrián-Tovar, David, Barrera-Ruíz, Uriel M., Silva, Salvador Ordaz, Sánchez, Imelda Virginia López, Melika, George & Pujade-Villar, Juli, 2020, Revision of the Amphibolips species of the ' nassa' complex from Mexico and central America (Hymenoptera: Cynipidae), pp. 1-50 in Zootaxa 4877 (1) on page 16, DOI: 10.11646/zootaxa.4877.1.1, http://zenodo.org/record/4567340, {"references":["Nieves-Aldrey, J.

Deposited in UB with the following labels: “P037, MEXICO, Cerro del Cubilete, Silao, Guanajuato, only galls without data, leg. JP-V, A. Equihua & E. Estrada”. Sexual females and males. We were unable to get specimens of the sexual generation and thus we follow the description of adults and galls given by Lyon (1959). Diagnosis. The asexual female of this species is characterized by a mesoscutum with sparse long white setae and discontinuous transversal carinate sculpture in anterior half. Most closely resembles A. salicifoliae for its glabrous shining, smooth speculum, simple tarsal claws, posterior scutellar depression absent, and forewing almost hyaline except for the infuscate margins of R1 and 2r veins. Amphibolips quercuspomiformis comb. nov. differs from A. salicifoliae by its colouration (black head, mesosoma and metasoma in dorsal view, but rufous metasoma laterally in A. quercuspomiformis comb. nov. while entirely brownish-rufous in A. salicifoliae; head faintly rugate dorsally and striae radiating from clypeus on lower face (coarsely rugate in A. salicifoliae); notauli shallow and entirely rugate (posteriorly smooth in A. salicifoliae) and ventral spine of hypopygium 2.2x as long as broad (0.8x in A. salicifoilae). Forewing colour pattern also resembles those of A. aliciae and A. kinseyi n. sp. but can be differenti-ated for tarsal claws with basal lobe (simple in A. quercuspomiformis comb. nov.); speculum sculptured in A. aliciae and A. kinseyi n. sp. (smooth and glabrous in A. quercuspomiformis comb. nov.), a less infuscate basal margin of radial cell (extended to basal third of radial cell in A. aliciae and A. kinseyi n. sp.); notauli deep and emarginate dorsally and with transverse carinae along sulci in A. aliciae and A. kinseyi n. sp. Galls of A. quercuspomiformis comb. nov. are similar to other species with galls that have a large globular shape and without a mottled surface; nevertheless, they are differentiable from all of these in colour (surface yellowish to orange-magenta when mature, turning to brownish orange when dry) and by being multilocular; it is the only Amphibolips multilocular gall so far known in the studied area. In USA (Arizona), A. ruginosus (Bassett, 1890) galls are also multilocular, but in this case, the larval chambers are not detachable from the host tissue (easily detachable in A. quercuspomiformis comb. nov.), 2.5 mm in diameter (longer in A. quercuspomiformis comb. nov.) with the surface rough and blackened and deeply and irregularly fissured (never in A. quercuspomiformis comb. nov.); adults with hyaline wings and metasoma yellowish brown (with a dark patch next to the basal part of radial cell and metasoma brownish-rufous in A. quercuspomiformis comb. nov.).

The gall is hard-walled, yellowish to rufous-magenta when mature and turning to brownish orange when dry, with smooth and naked surface; spongious internally, with hard filaments connecting the larval chambers with the base of the gall; up to 50 hardwalled larval chambers clustered in the center of the gall, easily separable from the firm; sometimes resembling the inquiline larval chambers; each larval chamber around 2.0–4.0 mm in diameter. Sexual galls. A toadstool-shaped gall arising singly, or occasionally in groups of two or three from the lamina of the underside of the leaves. Galls are tinged with rose or pink when young, although most are light-green in colour. Galls are monolocular, with the single cell occupying the space below the flared top of the gall. The elongated stem of the gall is solid. Hosts. Quercus agrifolia, Q. wislizenii, for both generations. Biology. Alternate sexual and asexual generations are known (Lyon 1959). Sexual galls appear from February to early April, mature in early May; adults emerged from mid-May to the first week of June. Asexual galls mature in October; adults emerged in November. Distribution. USA (California) and México (Baja California and Guanajuato states). Remarks. Kinsey (1922) named this species as Andricus pomiformis and described five varieties, considering Callirhytis maculipennis Kieffer 1904 one of them: A. pomiformis var descansonis (Kinsey 1922), A. pomiformis distinctus (Kinsey 1922), A. pomiformis pomiformis (Basset, 1881), A. pomiformis var maculipennis (Kieffer) and A. quercuspomiformis provincialis (Kinsey 1922). Later, Weld (1951), following Mayr’s work (1902), transferred this species to the genus Callirhytis and recognised only three of Kinsey’s varieties (var. descansonis, var distincta and var. provincialis). Later, Melika & Abrahamson (2002) concluded that this species belongs to the genus Amphibolips but did not formalize the nomenclatorial act for species transfer. Herein this nomenclatorial act is completed. According to Kinsey (1922), the morphological differences of these varieties included the notauli (from mostly indistinguishable within the mesosomal sculpture with notaular furrow rugose, to distinct with notaular furrow smooth posteriorly, and to distinct but shallow and furrow rugose); mesosoma with median sulci (absent except in var. distinctus); anterior parallel lines on the mesosoma (mostly continuous to discontinuous); lateral lines of the mesosoma (from prominent to fine and narrow); scutellar foveae (divided by a rugose and elevated area in all, or with median area also rugose but low); scutellar posteromedian depression (from absent to present, but variable in depth, deepest in var. provincialis); speculum (from glabrous and smooth to not completely smooth, with scattered punctuations and sometimes setae); areolet ranging from small to large, prolonged on the cubitus; forewing infuscation around the base of radial cell; and gall surface (present several projections on the surface, each ending in a short filament in var. distinctus and surface smooth and naked in the rest). Several characters are roughly differentiable or shared between the varieties such as the anterior parallel lines, the speculum, but others such as the median carina or the posteromedian depression of the mesoscutellum may be unique to a variety. Among the varieties, the most deviant is var. distinctus based on the distinct notauli, median sulci visible and the surface of the galls with projections. However, Kinsey (1922) comments that some var. distinctus specimens share characters of var. maculipennis (as well as var. provincialis had specimens similar to var. maculipennis). Similarly, the new material from Baja California present distinct notauli, smooth notaular furrow posteriorly as in var. distinctus, but the median sulci and scutellar posteromedian depression are absent, and the speculum is completely smooth and glabrous. The distribu-tion of the varieties is limited to California (USA) and range from the central to southern regions. All varieties have overlapping, or nearly so, distributions with at least another variety. The range of var. maculipennis includes localities from the range of var. descansonis, var. distinctus and var. provincialis, which occur almost exclusively in the southern regions. The variety pomiformis is limited to central California (San Francisco, Mount Diablo, Gilroy, and Salinas) and the closest known varieties are var. maculipennis and var. distictus (Yosemite Park and Merced Falls). Most of these characters also follow a continuous variation, and the distributions overlap in the southern regions for all, except var. pomiformis. Thus, there are not conspicuous character states to support these varieties as independent entities. Also, the host plant is Q. agrifolia in three of the varieties and Q. wislizenii in var. provincialis and var. distinctus. Both oaks are closely related and often form hybrids (Brophy & Parnell 1974). We consider all these varieties as intraspecific variations of Amphibolips quercuspomiformis comb. nov.

Amphibolips palmeri Basset species dubia Amphibolips palmeri Basset, 1890: 86. The type material is presumably lost (Buffington pers. com.). This species was described from a single specimen extracted from a gall collected from an unidentified Quercus species by Basset (1890). According to the author, the gall was donated by Mr. B. Pickman Mann and had the following label: “Summit of Sierra Madre, Chihuahua, México. Winter 1885–86, Dr. Edward Palmer”. Beutenmüller (1909) in his revision of the Amphibolips of North America broadened the distribution of this species to Guadalajara (Jalisco, México) for a gall deposited in the American Museum of Natural History, but did not add any new information to the description of the species. Amphibolips palmeri was not mentioned in Kinsey (1937) paper on Amphibolips of México. In the latest studies on Amphibolips (Melika et al. 2011; Nieves-Aldrey et al. 2012) as well as in this study, the type material of the species was not found. We provide the original description given Basset (1890) below: “Gallfly – Female. Entire body black. Head: face unevenly wrinkled, vertex and thorax deeply and irregularly wrinkled. Antennae black, very short, 13-jointed, first joint heavy, second joint short, third joint one-half longer than the first and second together, fourth joint one half as long as the third, remaining joints short, last joint a little longer than the twelfth. Mesothorax deeply and irregularly wrinkled with two obscure parallel lines and a line at the base of each wing. Parapsidal grooves faint and scarcely interrupt the rugosity of the surface. Mesoscutellum very coarsely wrinkled and conspicuously broader in the middle than on the anterior side, truncate and emarginate posteriorly; foveae large, rugose with a low irregular line separating them and a high ridge bounding them at the sides, the whole polished and shining. Abdomen black, second segment covering one-half of the whole, anterior half smooth and shining and with a few scattered hairs. The posterior half and the visible parts of the other segments distinctly reticulated or punctate, except a narrow-polished band on the margin of each. Legs black, shining with a few scattered hairs. Wings dark, smoky brown, with a very dark brown cloud covering the areolet and the lower half of the radial area; beyond this and extending across the radial area to almost the posterior margin is a light colourless area and the anterior margin from the dark, broad, first cross-vein to a short distance beyond the second cross-vein is of the same light colour; tip of wing beyond the pale area, dark smoky brown as below this pale area. Areolet very small, but well defined. Radial area open, large and broad. Length 6.5 mm.” Concerning to the gall, it is a large spherical spongious bud gall. Light yellowish brown; the outer shell thin but firm. Internally soft spongious tissue. Larval chamber round embedded in the spongious tissue. Diameter: 35 to 70 mm. Remarks. According to Melika et al. (2011), this species closely resembles A. dampfi and might well be synonymous. The type (female) of A. palmeri is lost, nevertheless the adults and galls descriptions are consistent. For the moment, this species is considered as species dubia until the type material appears, or new data can be examined., Published as part of Cuesta-Porta, Víctor, Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Cibrián-Tovar, David, Barrera-Ruíz, Uriel M., Silva, Salvador Ordaz, Sánchez, Imelda Virginia López, Melika, George & Pujade-Villar, Juli, 2020, Revision of the Amphibolips species of the ' nassa' complex from Mexico and central America (Hymenoptera: Cynipidae), pp. 1-50 in Zootaxa 4877 (1) on pages 23-24, DOI: 10.11646/zootaxa.4877.1.1, http://zenodo.org/record/4567340, {"references":["Beutenmuller, W.

Amphibolips castroviejoi Medianero & Nieves-Aldrey Amphibolips castroviejoi Medianero & Nieves-Aldrey, 2010: 48–52 Type material examined: HOLOTYPE. ♀ deposited in MNCN (Cat. nº 2022). PANAMA, Chiriquí, Carretera de Volcancito, Boquete 8º 43’ 23 07” N, 82º 27’ 19 07” W, 1404 m, Ex Q. salicifolia, (28.i.2008) ii.08, E. Medianero leg. Paratypes: 1♂ with same data as holotype. Diagnosis. This species is characterized by heavily darkened forewings with a clear cross-band at the distal third that reaches posterior margin of forewing both in males and females, mesoscutellum subquadrate posteriorly, and metasoma predominantly black and rufo-piceous ventrally. The forewing pattern most closely resembles the species group of A. bassae n. sp., A. bromus n. sp., A. cibriani and A. fusus for the distal clear cross-band that reaches posterior margin of wing, but the forewings of A. castroviejoi are completely darkened except for the distal cross-band (proximal half of forewing is hyaline in the rest of species, except for the male of A. bassae n. sp. which is completely infuscate except for a clear spot at the distal half of radial cell). The species most closely resembles A. basssae n. sp. by the similar coarse sculpture of mesoscutum and mesoscutellum, but median sulci on the mesoscutum are absent in A. castroviejoi (present in A. bassae n. sp.), metasoma is black and rufo-piceous ventrally in A. castroviejoi (ambarine to rufous in A. bassae n. sp.). Galls of A. castroviejoi are differ from all other known galls; they are large (on average 54 x 43 mm), irregularly spherical or globose, elongated at the base, with a thick peduncle, without apical tip, and with a smooth, mottled surface. Gall. A globose bud gall, 45–58 mm in diameter, with short elongation at the base forming a thick peduncle. Light green and mottled when mature, turning light brown when dry. Outer shell thin, hard. Internal parenchyma soft and spongious. Central larval chamber with a hard shell, 5–6 mm in diameter. A picture of the gall is given in Medianero & Nieves-Aldrey (2010: Figs 8 A–C). Host. Quercus salicifolia. Biology. Only the sexual generation is known. Galls were collected in January; adults emerged in February. Distribution. Panama.

This species is characterized with a posteromedian depression of mesoscutum projected anteriorly, reaching scutellar foveae; bottom of depression with subparallel transversal carinae and smooth interspaces that extend to posterior margin of mesoscutellum. This species closely resembles A. tarasco but can be differentiated by the rugose lateral margin of compound eye in A. hidalgoensis (alutaceous and finely carinated dorsolaterally in A. tarasco); mesoscutum uniformly rugate in A. hidalgoensis (less densely rugate in posteromedian area in A. tarasco) (Figs 11D, 11J); scutellar foveae round with median carina extending to full length of foveae, posteromedian depression connecting with foveae (foveae subtriangular posterior and medially limited by rugose sculpture, median carina shorter than total length of foveae in A. tarasco); metascutellum less than 1.8x as broad as high (more than 2.0x in A. tarasco) (Figs 4 E–F). Galls of both species are subglobose bud galls, but A. hidalgoensis has galls with a thin, uniformly coloured outer shell and soft spongious internal tissue, while galls of A. tarasco have a mottled surface and outer shell and internal spongious tissue that is rather hard (Figs 16 H–I). The gall is similar to other species with a large globular shape without a mottled surface; it is not differentiable from A. michoacaensis and A. jaliscensis, but differs from A. quercuspomiformis comb. nov., A. oaxacae, A. tarasco, A. kinseyi n. sp. and A. bassae n. sp. by having a deformable surface under applied finger pressure, because the parenchyma is relatively soft in A. hidalgoensis, A. jaliscensis and A. michoacaensis. Gall (Figs 15 A–B). Usually large, subglobose, detachable bud galls, sometimes with fine tip at apex. Maximum diameter 30–65 mm. Outer shell thin and fragile; internal tissue spongious and soft with central larval chamber about 5 mm in diameter. Hosts. Quercus acutifolia, Q. calophylla, Q. castanea, Q. crassifolia, Q. crassipes, Q. mexicana. Biology. Only females are known. We consider this species to be an asexual form as we have never obtained males after the emerging of more than 100 females from different localities. The mature galls were collected in late May to early June; most adults emerged soon after field collection, some were reared in November. Distribution. Mexico: Hidalgo, Mexico and Tlaxcala states. Remarks. After the examination of A. malinche types, we found great similarities between this species and A. hidalgoensis: lateral margin of eye rugulose; mesoscutum uniformly rugulose with finely alutaceous to smooth interspaces; forewing pattern within the morphological variability of A. hidalgoensis; mesoscutellum with longitudinal median depression posteriorly deep and shallow anteriorly, reaching scutellar foveae, with rugae forming transversal subparallel carinae along median depression; scutellar foveae rounded with distinct median carina, foveae smooth with sparse transversal carinae (Figs 5 A–B). Mesoscutellum is different in the holotype and the paratype of A. malinche; the holotype having an unusually broad median depression and short irregular median carina between scutellar foveae but it might be an aberrant variant of A. hidalgoensis; the paratype presented all the above mentioned similarities to A. hidalgoensis. Furthermore, the galls of both species are identical. Amphibolips malinche were sampled in the state of Tlaxcala and numerous specimens of A. hidalgoensis were collected 30 km away from the location of the two known specimens of A. malinche. The two specimens of A. malinche reared from galls of Q. mexicana, which shares distribution with the rest of host plant species (Q. calophylla, Q. crassifolia and Q. crassipes) in the states of Ciudad de México, Guanajuato, Hidalgo, México, Oaxaca, Puebla, Querétaro. Some morphological variability has been detected within this species: forewing pattern and metasomal tergum II with coriaceous sculpture. Forewing colour pattern is variable in basal cell pigmentation, sometimes clearer than first cubital and radial cell; also, distal third of radial cell sometimes presents a clear area shortly extended into second cubital cell. This character was used by Nieves-Aldrey et al. (2012) to identify A. jaliscensis (see below) and A. malinche, but we do not consider it a reliable character for A. malinche as we have encountered similar patterns in specimens of A. hidalgoensis. The coriaceous sculpture in metasomal tergum II is present in all the species with anterior margin of forewing infuscate, and particularly variable in A. hidalgoensis. This character ranges from coarsely coriaceous and extended past half-length of tergum, to be almost inconspicuous and confined to the posterior third of tergum bordering punctures. This species is currently the only one known to have such a wide range but no correlation with other characters has been found. Amphibolips hidalgoensis is by far the most frequently collected Amphibolips species in Mexico. Such sampling bias might be concealing other, poorly sampled, species’ variability and attributing as intraspecific variability to a possible widely spread interspecific common trait. Alternatively, A. hidalgoensis is probably a complex of species that cannot be sorted out by only morphological criteria. For all these reasons we consider A. malinche as a syn. nova of A. hidalgoensis., Published as part of Cuesta-Porta, Víctor, Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Cibrián-Tovar, David, Barrera-Ruíz, Uriel M., Silva, Salvador Ordaz, Sánchez, Imelda Virginia López, Melika, George & Pujade-Villar, Juli, 2020, Revision of the Amphibolips species of the ' nassa' complex from Mexico and central America (Hymenoptera: Cynipidae), pp. 1-50 in Zootaxa 4877 (1) on pages 14-15, DOI: 10.11646/zootaxa.4877.1.1, http://zenodo.org/record/4567340, {"references":["Melika, G., Equihua-Martinez, A., Estrada-Venegas, E.

Striatoandrius barriosi (Medianero and Nieves- Aldrey 2019) n. comb. R e c e n t l y d e s c r i b e d s p e c i e s f r o m P a n a m a (Medianero and Nieves-Aldrey 2019). Morphologically, it has the second metasomal segment striated as S. georgei, S. nievesaldreyi and S. sanchezi n. sp. and the notauli are percurrent as S. nievesaldreyi. Striatoandricus barriosi differs from S. nievesaldreyi in that its second mesosomal tergite completely sculptured, without smooth dorso-lateral area with longitudinal striae strong, well-marked and visible, almost reaching posterior margin of metasomal tergite (usually with a dorso-lateral area smooth and shiny with striae weak, slightly marked and incomplete, not reaching margin of metasomal tergite in S. nievesaldreyi), mesoscutum longer than broad (as long as broad in S. nievesaldreyi), dorsal area of mesopleuron weakly sculptured to smooth (entirely sculptured in S. nievesaldreyi), forewing venation strongly pigmented (brown veins in S. nievesaldreyi) and Rs + M vein conspicuously connected to lower half of basal vein (Rs + M vein not connected to basal vein in S. nievesaldreyi). © 2020 Academia Sinica, Taiwan © 2020 Academia Sinica, Taiwan © 2020 Academia Sinica, Taiwan The gall is a fused mass of larval chambers as also occurs in S. georgei, S. nievesaldreyi and S. sanchezi n. sp. Galls of S. barriosi occurs in Q. bumelioides Liebm. and Q. insignis M. Martens and Galeotti (section Quercus). Remarks: In Medianero and Nieves-Aldrey (2019) mention that this species can also be differentiated from S. nievesaldreyi by its color (black in S. barriosi and ambarine in S. nievesaldreyi). Nevertheless, after studying long series of S. nievesaldreyi, the coloration is very variable in this species including specimens completely ambarine, specimens ambarine with variable black marks or specimens completely black. © 2020 Academia Sinica, Taiwan Also, the authors of the same paper mention that the gall of S. barriosi is similar to that of Andricus guatemalensis (Cameron 1883); this species has been considered incertae sedis by Pujade-Villar et al. (2011) because is not possible to differentiate the species according to the morphology of galls. In the original description, Cameron (1883: 71) mentions that the gall of Cynips guatemalensis is a hard mass covered of a long pilosity, but the adults obtained corresponds to an inquiline Synergus dorsalis Cameron (see the dissertation in Ritchie and Shorthouse 1987)., Published as part of Cuesta-Porta, Víctor, Arnedo, Miquel A., Cibrián-Tovar, David, Barrera-Ruiz, Uriel M., García-Martiñón, Rosa D., Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Clark-Tapia, Ricardo, Romero-Range, Silvia & Pujade-Villar, Juli, 2020, A New Genus of Oak Gall Wasp, Striatoandricus Pujade-Villar (Hymenoptera: Cynipidae: Cynipini) from America with Descriptions of Two New Mexican Species, pp. 1-21 in Zoological studies (Zool.

Distribution: México, described from material collected in the Sierra de Nayarit (Jalisco, México). Its distribution also includes in the states of Ciudad México, Hidalgo, Michoacán, Morelos and Tlaxcala. Remarks: Kinsey (1920) described Andricus mexicanus from four adults that emerged in 1919 from galls on the upper side of leaves. Those galls were collected in 1900 by Diquet in Sierra de Nayarit (Jalisco, México) presumably from Q. magnifolia Née (= Q. macrophylla Née). Kinsey (1920) assigned to this species the individuals determined as Andricus mexicana Bassett, 1890 and Cynips guatemalensis Cameron, 1883 from the collections of Bassett (1890) at Guadalajara mountains (México) and Cameron (1883) at San Jerónimo (Guadalajara, México), respectively. A solution for the homonymy between Kinsey’s and Bassett’s species was proposed in Pujade-Villar et al. (2011) by changing the name of Andricus mexicanus Kinsey 1920 to Andricus nievesaldreyi Pujade-Villar 2011. The species A. mexicana Bassett and C. guatemalensis Cameron were only described through velvety galls on leaves. Both adults with smooth metasoma (Andricus tecturnarum group) and with striate metasoma (Striatoandricus) emerge from this type of galls from USA and México. Thus, Pujade-Villar et al. (2011) considered those two species incertae sedis until similar galls are collected at the type localities and the adults emerge. There exists a big morphological variability in adults of this species in the following characters: (i) the color is very variable, usually is ambarine with black marks but some specimens lack black marks and others are black and (ii) the metasoma sculpture has smooth areas with variably extension., Published as part of Cuesta-Porta, Víctor, Arnedo, Miquel A., Cibrián-Tovar, David, Barrera-Ruiz, Uriel M., García-Martiñón, Rosa D., Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Clark-Tapia, Ricardo, Romero-Range, Silvia & Pujade-Villar, Juli, 2020, A New Genus of Oak Gall Wasp, Striatoandricus Pujade-Villar (Hymenoptera: Cynipidae: Cynipini) from America with Descriptions of Two New Mexican Species, pp. 1-21 in Zoological studies (Zool.

(2011, Q. mexicana Humb. and Bonpl.) is wrong, the correct host is Q. deserticola Trel. All host are new records from this species. Distribution: México, described from material collected in the Parque Nacional del Bosque del Pedregal (Bosque de Tlalpan, Ciudad de México). Its distribution is extended to have collected it in the states of Hidalgo, Jalisco, Michioacan, Morelos, Puebla and Zacatecas. Remarks: Adults of this species have high morphological variability in the following characters: (i) the color is very variable, usually is ambarine with black marks but some specimens lacks black marks and others are almost black; (ii) OOL is usually shorter than diameter of posterior ocelli, but in some specimens OOL is larger; (iii) the length of notauli are usually short reaching the tegulae level but in some specimens are longer reaching until 3/4 of mesoscutum length; (vi) the metasoma sculpture is usually striated in second metasomal tergite but is some specimens exist also a reticulate sculpture more or less extended from margin of this tergite towards the basal area; (v) usually the second metasomal tergite is completely sculptured but in some specimens there is smooth in dorsal small area. The authors suggest that this variability may be indicative of a group of species. Further research should asses this matter.

Striatoandricus Pujade-Villar, new genus (Figs. 1–10) urn:lsid:zoobank.org:act: 9F4FF2CD-1674-4C63-AE7F-543113BD0C99 Type species: Andricus georgei Pujade-Villar 2011 Etymology: The genus is named after the special sculpture of its metasomal segments and its original assignment of (and morphological similarity to) oak gall wasp genus Andricus. Gender: Masculine. Diagnosis: Only asexual females are known. Striatoandricus gen. nov. belongs to the group of genera which the transscutal articulation is present and the asexual females are fully-winged; in addition, the mesoscutum never has transversal carinae neither rugae, the hind femora have no lobe in the posterior margin, the malar sulcus is absent, the ventral spine of the hypopygium is slender without apical tuft, tarsal claws with a basal tooth and metasoma longitudinally carinated. If we do not consider the sculpture of the metasoma, Striatoandricus gen. nov. morphologically resembles Andricus, but in the genus Andricus, the metasoma is smooth, without sculpture. © 2020 Academia Sinica, Taiwan In terms of metasomal sculpture, Striatoandricus gen. nov. mostly resembles Kokkocynips with striate and reticulate metasomal tergites. In Striatoandricus gen. nov., tarsal claws with distinct strong basal lobe, prominent part of ventral spine of the hypopygium 1.5– 1.8 times longer than broad, head rounded in front view, nearly as broad as high, length of antennae nearly equal to length of the body, F2 and subsequent flagellomeres thin, long, F1 1.2–1.3 times longer than F2, lateral propodeal carinae curved outwards in the middle, central propodeal area smooth, shiny, lateral propodeal area coriaceous; 2nd metasomal tergite with large and dense patch of setae laterally, striated in the posterior half at least, all subsequent tergites reticulate, induce detachable multilocular or aggregate pubescent leaf galls. In Kokkocynips, tarsal claws are simple, without basal lobe, the prominent part of ventral spine of the hypopygium is 3.0–3.3 times longer than broad, head transverse in frontal view, broader than high, length of antennae nearly equal to length of head + mesosoma, F2 and subsequent flagellomeres are stout, shorter, F1 2.0 times longer than F2, lateral propodeal carinae toward distal part of propodeum gradually curved outwards, central and lateral propodeal areas dull rugose; all tergites uniformly reticulate, 2nd metasomal tergite with sparse lateral hairs, induce rounded detachable soft unilocular twig galls. The galls are morphologically very similar to Andricus group tecturnarum, but in this case the adults have the metasoma completely smooth and shiny. Description: Asexual female, body length 1.7–4.0 mm. Color: Amber usually with black areas variably extended to black. Yellowish legs, last femur dark. Chestnut venation. Head: Transversally ovoid, 1.2–1.5 as broad as high in frontal view, with gena slightly broadened behind the eye, alutaceous to coriaceous, with sparse white setae.

Maxillary palps 5-segmented and labial palps 3-segmented (Fig. 1a). Antenna short, longer than head + mesosoma, with 11–13 flagellomeres, being F1 equal or longer than F2. Mesosoma: Pronotum impressed along anterior margin, delicately coriaceous dorsally and laterally, almost smooth or with some transversal carinae (Fig. 1b–e); propleuron sculptured, alutaceous to coriaceous, with sparse setae. Mesoscutum coriaceous, usually without carinae or rugae; as long as broad or slightly longer than broad (greatest width measured across mesoscutum level with base of tegulae). Notauli present, complete or incomplete; parapsidal lines present sculptured; median mesoscutal line absent or not; anterior parallel lines distinct and sculptured; parascutal carina broad, extending to 2/3 of mesoscutum length. Mesoscutellum rounded, as broad as long or slightly longer, pubescent, alutaceous to coriaceous, rugose at least laterally, overhanging metanotum, not margined. Scutellar foveae transverse, separated. Mesopleuron alutaceous, with carinae or rugae. Dorsal axillar area alutaceous, with white setae; lateral axillar area alutaceous, with few setae; subaxillular bar smooth, glabrous, triangular, posteriorly as high as long; metapleural sulcus reaching mesopleuron at half of its height at least. Metascutellum coriaceous, rectangular, ventrally concave, glabrous ventral impressed area; metanotal trough smooth, pubescent or not; central propodeal area smooth and glabrous, without longitudinal central carina; lateral propodeal carinae curved; lateral propodeal area with dense setae without piliferous points. Nucha with longitudinal carinae. Legs: All tarsal claws with strong basal lobe. Forewing: longer than body, hyaline, pubescent, ciliated on margin, veins conspicuous, radial cell 3–4 times as long as broad, open; areolet triangular, closed and distinct; Rs + M not reaching basalis, its projection reaching basalis at half its length. Metasoma: Slightly longer than mesosoma, slightly longer than high in lateral view. Length of 2nd metasomal tergite equal to half or 2/3 of metasoma’s total length, with lateral setae, striated or partially striated and reticulated; subsequent tergites shorter, sculptured, striated and/or reticulated. Ventral spine of hypopygium needle-like, prominent part of ventral spine of hypopygium short, at most 4.0 times as long as broad from ventral view, with sparse setae, extending beyond apex of spine without forming a tuft. Galls: Located in the lower part of the central vein of the leaf, in the upper part, or in the branches. It appears as a globose structure with long and dense pubescence without being brittle. They are yellowish, brown, sometimes purple or violet pink. The pubescence completely covers the larval chambers, which are fused or individualized but together, in a variable number between 3 and 30; each individual gall is cylindrical, light brown in color, with a thick hard wall, from which the pubescence emerges.

This is the second contribution of the authors to the knowledge of the Cynipidae in Mexico. The only Aylacini species cited for Mexico, Aylax rufipes (Cameron, 1884), is transferred to the family Figitidae as Myrtopsen rufipes (Cameron, 1884) n. comb. The possibility of finding native or invasive species of Aylacini in Mexico is discussed. Concerning the inquiline cynipids, included in the Synergini, the species richness of Synergus, Saphonecrus and Ceroptres is far from being well known, with only two Synergus species cited; Periclistus is an inquiline genus absent in Mexico due to the absence of the host galls; which belong to the Diplolepidini. Lastly, even if the tribes Diplolepidini, Eschatocerini and Pediaspidini have never been cited, their possible presence is discussed., Ésta es la segunda aportación de los autores al estado de conocimiento de los Cynipidae de México. La única especie de Aylacini citada hasta el momento de México, Aylax rufipes (Cameron, 1884), es transferida a la familia Figitidae como Myrtopsen rufipes (Cameron, 1884) n. comb. Se discute la posibilidad de encontrar especies autóctonas o invasoras de Aylacini en México. En lo que se refiere a los cinípidos inquilinos, incluidos en la tribu Synergini, la riqueza de Synergus, Saphonecrus y Ceroptres dista mucho de ser conocida, habiéndose citado solamente dos especies de Synergus; Periclistus es un género inquilino inexistente en México debido a la ausencia de las agallas huésped, pertenecientes a tribu Diplolepidini. Finalmente, aunque las tribus Diplolepidini, Eschatocerini y Pediaspidini nunca se han citado, se discute su posible presencia.
