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.

Amphibolips nevadensis Nieves-Aldrey & Pascual Amphibolips nevadensis Nieves-Aldrey & Pascual, 2012. In Nieves-Aldrey et al., 2012: 19–22. Material examined. HOLOTYPE. ♀ deposited in MNCN (Cat. nº 2252; Code: 89217). MEXICO, Jalisco, Nevado Colima, Ciudad Guzmán, 2300 m; Ex Q. candicans, (20.viii.2009), leg. E. Pascual. 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). Herein we provide the mesosomal view of a type male of A. nevadensis (Fig.12E)., 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 22-23, DOI: 10.11646/zootaxa.4877.1.1, http://zenodo.org/record/4567340, {"references":["Nieves-Aldrey, J.

Amphibolips bromus Pujade-Villar & Cuesta-Porta n. sp. urn:lsid:zoobank.org:act: 8256CC0E-6C41-48DE-8F9B-15F295ABD670 Type material. HOLOTYPE. ♀ (deposited in UB) with the following labels: “ MEXICO, Predio La Victoria, Acaxochitlan, Hidalgo ” (white label), “ Q. affinis, (03.v.2014) 16-31.v.2014, leg. U. Barrera-Ruiz ” (white label). “ Holotype Amphibolips bromus Pujade Villar & Cuesta-Porta n. sp., desig. Cuesta-Porta, 2020” (red label). Additional material. Galls collected in Sta. Fe (Mexico State) in June 2018 and June 2019 on Q. crassipes Etymology. The name refers to the genus Bromus (Poaceae), because the gall resembles some of the flowers of the species in this genus. Diagnosis. The new species is characterized by the forewing colouration: infuscate on the distal half with a hyaline cross band covering the whole width of the wing on distal third; mesoscutellum slightly longer than broad with posterolateral projections ending in a carina, posteriorly defining the margin of the depression on the mesoscutellum; scutellar fovea with a faint median carina; antennae chestnut brown, sometimes slightly lighter distally. Most closely resembles A. bassae n. sp. but can be differentiate by an inconspicuous median sulcus between scutellar foveae (visible through the sculpture in A. bassae n. sp.), mesoscutellum longer than broad (broader than long in females of A. bassae n. sp.), with margin of posterior depression defined laterally by carinae in posterior view (not marginate in A. cibriani and A. bassae n. sp.). Galls of A. bromus n. sp. differ from all earlier known Mexican Amphibolips species; they are strongly elongate with peduncle and apex very thin and long, internally almost without spongious tissue.
