Female Unknown. Comments Using Nixon’s (1957) key to the genera of Belytinae, Pantolyta augustinusii sp. nov. keys out near Acropiesta Förster, 1856 because of the following characters: notauli present, second flagellomere not modified; scutellum without foveae; mandibles not forming a beak; marginal vein shorter than both radial cell and its distance from basal vein; pronotum with reduced epomia; large tergite markedly tapering towards petiole. Pantolyta augustinusii especially share with Acropiesta the antennal shelf prominent with toruli separated by a furrow, the 14-segmented antennae with F1 modified, the pronotal shoulders rounded, the notauli complete, the anterior scutellar pit large and quadrate, the propodeum with median keel simple, the fore wing venation with C, Sc+R, M+Cu, Rs, basal and marginal vein tubular, the petiole cylindrical (Macek 1998). However, due to their close similarities, Acropiesta has recently been synonymized under Pantolyta by Chemyreva & Kolyada (2021). Four other Pantolyta species are present in Baltic amber, two having been described under Acropiesta and not duly transferred by Chemyreva & Kolyada (2021): Pantolyta antiqua Buhl, 1999, Pantolyta janzeni (Buhl, 2002) comb. nov., Pantolyta perrichoti (Jouault & Nel, 2020) comb. nov. and Pantolyta somnulenta Maneval, 1938. Pantolyta antiqua has the marginal vein as long as its distance from basal vein whereas it is distinctly shorter in Pantolyta augustinusii (Buhl 1999); P. janzeni has a distinct emargination of F 1 in the male antenna, the marginal vein is shorter and the postmarginal vein is longer than in Pantolyta augustinusii (Buhl 2002); P. perrichoti has the median propodeal keel bifid (Jouault & Nel 2020) and P. somnulenta has the radial cell shorter than the marginal vein (Maneval 1938).

Etymology We dedicate this species to the Knud Højgaard Foundation, who generously contributed to funding for purchasing the amber pieces studied. The specific epithet is to be treated as a noun in genitive case. Type material Holotype NHMD-608408, a complete female; paratype NHMD-608400, a slightly damaged female. Locality and horizon Baltic amber is considered to be of Bartonian–Priabonian age, ca 34–38 Ma. Description Female BODY. BL = 4.8–5.3 mm. Body slightly pubescent, smooth and shiny. Head nasiform (HeL = 0.77– 0.89 mm), with sparse short hairs posteriorly; eye almond-shaped, glabrous; antennal shelf strongly prominent; antenna 15-segmented, with short heterogeneous setae; scape as long as head; pedicel thinner; F1 one and a half times as long as pedicel or other flagellomeres; F2–F13 gradually lengthening; F13 tapering at apex and slightly shorter than F1 (antennomere length of holotype, in mm: Sc-0.72; P-0.19; F1-0.29; F2-0.11; F3-0.12; F4-0.11; F5-0.12; F6-0.10; F7-0.11; F8-0.13; F9-0.13; F10-0.14; F11-0.15; F12-0.15; F13-0.28); mandibles simple.

Male Unknown. Comments Using Nixon’s (1957) key, Belyta knudhoejgaardi sp. nov. keys out to Belyta because of the following characters: macropterous, notauli present, mandibles of ordinary form, scutellum without a row of foveae along posterior margin, marginal vein shorter than its distance from basal vein, pronotum elongate, without a hollow on each side (= pronotal pits), epomia present, median keel of propodeum simple, petiole more than one and a half time as long as wide. The flattened body is generally accepted to diagnose Belyta spp. (Macek 1996) and is present in Belyta knudhoejgaardi, strengthening the placement of the species in Belyta. Following the key to European species of Belyta of Macek (1996), Belyta knudhoejgaardi sp. nov. keys out between B. subclausa Kieffer, 1916 and B. validicornis Thomson, 1858. It differs from the first by having a marked epomia and from the second by having the median propodeal keel simple (Macek 1996). The diagnostic character for Belyta knudhoejgaardi is the curiously marked longitudinal keel on the mesopleuron, which is absent in other species of Belyta. From the Eocene of Florissant is known B. mortuella Brues, 1910 (attributed to Belyta s. lat.), which differs from B. knudhoejgaardi by being shorter and having a less flattened body (Brues 1910)., Published as part of Brazidec, Manuel & Vilhelmsen, Lars, 2022, New species of belytine and diapriine wasps (Hymenoptera: Diapriidae) from Eocene Baltic amber, pp. 57-86 in European Journal of Taxonomy 813 on pages 61-62, DOI: 10.5852/ejt.2022.813.1733, http://zenodo.org/record/6468167, {"references":["Nixon G.

Comments Using Nixon’s (1957) key, Pantoclis globosa sp. nov. keys out to Pantoclis because of the following characters: antennae inserted on a frontal prominence, mandibles not forming a beak or sickle-shaped, notauli present, scutellum without foveae along posterior margin, marginal vein nearly as long as its distance from basal vein and presence of ring-like segments beyond the large tergite, marginal vein shorter than radial cell, epomia distinct, median propodeal keel simple, petiole at most one and a third times as long as its apical width. Pantoclis globosa also fits in Pantoclis according to the diagnosis of Hou et al. (2016). It differs from most extant representatives of Pantoclis by having the marginal vein much longer than the r-rs (Nixon 1957; Sharma 1980; Buhl 1998). Pantoclis longiscapa Chambers, 1974 has a similar fore wing configuration but differs by having F1 very long and F2 distinctly longer than the following flagellomeres (Chambers 1974). Pantoclis deperdita Brues, 1906, from the Eocene of Florissant has a shorter radial cell and marginal vein (Brues 1906) and is therefore considered as a different species from P. globosa., Published as part of Brazidec, Manuel & Vilhelmsen, Lars, 2022, New species of belytine and diapriine wasps (Hymenoptera: Diapriidae) from Eocene Baltic amber, pp. 57-86 in European Journal of Taxonomy 813 on pages 68-69, DOI: 10.5852/ejt.2022.813.1733, http://zenodo.org/record/6468167, {"references":["Nixon G.

Pantolyta chemyrevae sp. nov. urn:lsid:zoobank.org:act: 626E3F04-AB34-45C2-AA5A-82AD0A85CC8E Fig. 5A–C, Table 1 Diagnosis Eye round, extending at most a fourth of head length; scape as long as pedicel and first three flagellomeres combined; F1 two times as long as wide, narrower than pedicel; F2–F13 gradually widening towards apex (Fig. 5A–B); epomia present; anterior scutellar pit suboval, wider than shortest distance between notauli; plicae projecting posteriorly; fore wing not reaching middle of propodeum (brachypterous morph; Fig. 5A–B); petiole slightly longer than wide (Fig. 5C); gaster fusiform, elongate and tapering at apex; T2 striated dorsally at junction with petiole; ovipositor long, subequal in length to gaster (Fig. 5A). Etymology The species is dedicated to Vasilisa Chemyreva, Russian entomologist, in acknowledgment of her numerous publications on Diapriidae from the Palearctic region. The specific epithet is to be treated as a noun in the genitive case. Type material Holotype NHMD-608448, a complete female partially hidden by a milky coat. Locality and horizon Baltic amber is considered to be of Bartonian–Priabonian age, ca 34–38 Ma. Description Female BODY. BL = 2.43 mm. Head smooth, bare (HeL = 0.37 mm); eye round, small, less than a third of head length (ED = 0.11 mm); antenna bearing numerous short setae; toruli separated by shallow cleft; scape as long as pedicel and first three flagellomeres combined, at least as long as head; pedicel three times as long as wide; 13 flagellomeres; F1 two times as long as wide, narrower than pedicel; following flagellomeres gradually widening towards apex; F13 largest and longest of all (antennomeres length of holotype, in mm: Sc-0.46; P-0.16; F1-0.12; F2-0.08; F3-0.08; F4-0.08; F5-0.09; F6-0.08; F7-0.08; F8- 0.08; F9-0.08; F10-0.10; F11- 0.10; F12; 0.11; F13-0.19); mandibles simple, just crossing at tip; labial palpi three-segmented, first long, second narrowing at apex and third wider. MESOSOMA.

Male Unknown. Comments Using Nixon’s (1957) key, Pantolyta chemyrevae sp. nov. keys out to Pantolyta Förster, 1856 because of the following characters: brachypterous, toruli rims without a distinct cleft, antennae 15-segmented, epomia on pronotum defined at pronotal collar, notauli present on mesoscutum, lower side of gaster slightly down curved. With the keys to species of Pantolyta provided in Chemyreva & Kolyada (2019) and Nixon (1957), P. chemyrevae keys out near P. stylata Kieffer, 1908 (= P. vernalis sensu Nixon 1957) but has the antennal shelf less prominent and a longer scape (Chemyreva & Kolyada 2019). Among the Baltic amber species, it differs from other Pantolyta species as follow: P. antiqua is macropterous and has F1 more than two times as long as pedicel; Pantolyta augustinusii has the toruli separated by a distinct cleft, the mesoscutum bearing long hairs and the plicae not projecting posteriorly; P. janzeni and P. perrichoti has a longer petiole, more than two times as long as wide; P. somnulenta is very similar to P. chemyrevae sp. nov. but is macropterous, has anterior scutellar pit narrower than P. chemyrevae and the plicae less produced posteriorly., Published as part of Brazidec, Manuel & Vilhelmsen, Lars, 2022, New species of belytine and diapriine wasps (Hymenoptera: Diapriidae) from Eocene Baltic amber, pp. 57-86 in European Journal of Taxonomy 813 on pages 72-73, DOI: 10.5852/ejt.2022.813.1733, http://zenodo.org/record/6468167, {"references":["Nixon G.

Female Unknown. Comments Using Nixon’s (1957) key, Cinetus elongatus sp. nov. keys out near Leptorhaptus Förster, 1865 sensu Nixon (1957) because of the following characters: fourth antennal segment not modified, mandibles of ordinary form, scutellum without a row of foveae along posterior margin, marginal vein hardly shorter than the radial cell, petiole much longer than wide, notauli subparallel, terminates in scutellar hollow. Leptorhaptus is currently regarded as a synonym of Cinetus (Masner 1964). Cinetus elongatus displays all the diagnostic characters of Cinetus provided by Quadros & Brandão (2017), especially the large anterior scutellar pit, the posterior extremity of notauli directed toward a point within the anterior scutellar pit, the marginal vein shorter than radial cell and slightly shorter than its distance to basal vein. Among the Baltic amber species, it differs from other Cinetus species as follow: C. balticus has the scape as long as F1 (longer in Cinetus elongatus sp. nov.), the petiole shorter (ratio length/middle height: 4 vs 5.3) and the marginal vein longer than its distance from basal vein; Cinetus breviscapus sp. nov. has the scape shorter than F1, the petiole shorter (ratio length/middle height: 2.8), the marginal vein longer than its distance from basal vein and the postmarginal vein shorter than radial cell; C. inclusus has a shorter petiole (ratio length/middle height: 1.5) and a smaller body (1.9 mm)., Published as part of Brazidec, Manuel & Vilhelmsen, Lars, 2022, New species of belytine and diapriine wasps (Hymenoptera: Diapriidae) from Eocene Baltic amber, pp. 57-86 in European Journal of Taxonomy 813 on pages 66-68, DOI: 10.5852/ejt.2022.813.1733, http://zenodo.org/record/6468167, {"references":["Nixon G.

Comments In Masner & García’s (2002) keys to the genera of Diapriinae, Doliopria baltica sp. nov. keys out to Doliopria Kieffer, 1910 because of the following characters: frons unarmed, antenna 11-segmented, notauli absent, wings fully developed, Sc+R separate from anterior margin of wing, basal vein absent. The description of the specimen is consistent with the original diagnosis of the genus by Kieffer (1910) and the revised diagnosis of Masner & García (2002). Doliopria baltica differs from extant representatives of this genus as follow: D. americana Fouts, 1926 has a two-segmented club (Fouts 1926); D. brachyptera Ogloblin, 1960 has F9 more lengthened and is brachypterous; D. foersteri Ogloblin, 1960 has short hairs on eyes, flagellomeres longer than wide and lacks the anterior scutellar pit; D. equatoriana Ogloblin, 1960 has F2–F5 longer than wide (Oglobin 1960); D. collegii Ferrière, 1929 has F9 longer (Loiácono et al. 2013); D. flavipes Kieffer, 1910 has F5–6 as long as wide and the petiole shorter (Kieffer 1910); D. myrmecobia Kieffer, 1921 has a two-segmented club and the apical flagellomere sharply pointed at the apex (Loiácono et al. 2013)., Published as part of Brazidec, Manuel & Vilhelmsen, Lars, 2022, New species of belytine and diapriine wasps (Hymenoptera: Diapriidae) from Eocene Baltic amber, pp. 57-86 in European Journal of Taxonomy 813 on pages 77-79, DOI: 10.5852/ejt.2022.813.1733, http://zenodo.org/record/6468167, {"references":["Masner L. & Garcia J.

Etymology The specific epithet refers to its similarity with the extant species Pantolyta macrocera (Thomson, 1858) and is to be treated as an adjective. Type material Holotype NHMD-608468, a complete female. Locality and horizon Baltic amber is considered to be of Bartonian–Priabonian age, ca 34–38 Ma. Description Female BODY. BL = 3.52 mm. Head glabrous, smooth, as high as long (HeL = 0.50 mm); eye round, small, less than a third of head length (ED = 0.18 mm); frontal prominence elongate; toruli facing upwards; antenna slightly but homogeneously pubescent; scape longer than head length; pedicel conical, thinner at base; F1 second longest; F2–F12 of subequal length, gradually widening; F12 as long as wide; F13 widest and longest, conical (antennomeres length, in mm: Sc- 0.58 mm; P-0.11; F1-0.17; F2-0.10; F3-0.10; F4- 0.11; F5-0.11; F6-0.11; F7-0.12; F8-0.11; F9-0.11; F10-0.11; F11-0.11; F12-0.12; F13-0.21); mandibles of ordinary form. MESOSOMA. Shorter than metasoma (MsL = 1.10 mm); pronotum not elongate, with straight posterior margin, epomia absent; mesoscutum convex, with notauli deep and complete; anterior scutellar pit large, rounded; scutellum sub-quadrate, without posterior scutellar pits; propodeum dorsally with prominent plicae, median keel simple. Fore wing very reduced, hardly reaching posterior margin of petiole (FwL = 1.04 mm). Hind wing reduced, shorter than fore wing (HwL = 0.52 mm). Legs slender, with only hind coxa widened; erect setae along hind tibia and tarsomere; tibial spur formula 1-2-2; tarsal claws simple. METASOMA. Petiole 1.3 times as long as wide (PtL = 0.28 mm; PtW = 0.22 mm), longitudinally ribbed; gaster fusiform and elongate (GL = 1.64 mm; GH = 0.59 mm); S2 and T2 longest, covering anterior half of gaster; T2 striated medially at junction with petiole; three ring-like segments visible posteriorly to large tergite; apical sternites fused into long, smooth triangle; ovipositor exerted, shorter than gaster (OL = 0.74 mm). Male Unknown Comments The specimen was originally identified as the extant species Pantolyta macrocera (Thomson, 1858) by Buhl (2002) because of the brachypterous morph. However, we can observe some differences on the petiole and gaster. Pantolyta similis sp. nov. displays numerous fine longitudinal ribs dorsally on the petiole whereas there are fewer ribs in P. macrocera. Additionally, P. macrocera has shorter and stronger medial striations on T2 than Pantolyla similis (Chemyreva & Kolyada 2021: fig. 11g). Among the Baltic amber species, it differs from other Pantolyta species as follows: P. antiqua and P. somnulenta are macropterous and have a shorter petiole; Pantolyta augustinusii sp. nov. has the epomia present, whereas it is absent in Pantolyta similis sp. nov.; Pantolyta chemyrevae sp. nov. has the epomia present, the anterior scutellar pit more quadrate, the petiole more elongate and the striations on T2 shorter; P. janzeni and P. perrichoti has a longer petiole, more than two times as long as wide.

Etymology The specific epithet is to be treated as an adjective and is composed of ‘ brevi- ’, meaning ‘short’, and ‘- scapus ’, a reference to the small size of the scape. Type material Holotype NHMD-300622, a complete male. Locality and horizon Baltic amber is considered to be of Bartonian–Priabonian age, ca 34–38 Ma. Description Male BODY. BL = 3.61 mm. Head with sparse long hairs (HeL = 0.47 mm); eye oval, glabrous; antennae inserted on transverse shelf; 14 antennomeres with uniform pilosity; scape elongate, less than five times as long as wide; pedicel rounded, as long as wide; flagellomeres elongate, cylindrical; F1 1.2 times as long as scape, with a deep emargination covering almost half of segment; F2–F6 slightly shorter, of subequal length; F6–F12 decreasing in size but still much more longer than wide; F12 tapering at apex (antennomeres length, in mm, when possible: Sc-0.32; P-0.06; F1-0.39; F2-0.34; F3-0.32); mandibles of ordinary form, not forming a beak. MESOSOMA. Shorter than metasoma (MsL = 1.21 mm); pronotum without epomia, only visible in lateral view; mesoscutum smooth; notauli deep, diverging at posterior terminations toward a point outside scutellum; anterior scutellar pit bean-shaped; scutellum without posterior scutellar pits; mesopleuron with epicnemial pit, epicnemial bridge and subalar bridge present; propodeum with prominent plicae; median propodeal keel simple. Fore wing hyaline, uniformly micropubescent (FwL= 3.58 mm); venation complete with C, Sc+R, basal vein, M+Cu, marginal vein, r-rs and Rs pigmented; marginal vein very long, longer than its distance from basal vein and as long as radial cell; postmarginal vein fading after middle of radial cell; Rs proximally directed toward base of wing; M inconspicuous towards apex; Cu short and nebulous; radial cell closed. Hind wing narrow, with C pigmented and basal cell opened (HwL = 2.23 mm). Legs slender, covered with setae; tibial spur formula 1-2-2; hind tibia and tarsomeres with long recumbent hairs. METASOMA. Petiole elongate, almost three times as long as its middle height (PtL = 0.56 mm; PtW = 0.19 mm), with longitudinal ribs; gaster globose, oval, smooth (GL = 1.37 mm; GH = 0.71 mm); six segments identifiable; T2 longest, covering two thirds of gaster; other tergites reduced, decreasing in length until they become indistinguishable; S2 longest, longer than T2; following sternites very short; pygidium and hypopygium at least as long as previous segments; genitalia internalized. Female Unknown. Comments Using Nixon’s (1957) key, Cinetus breviscapus sp. nov. keys out to Cinetus Jurine, 1807 because of the following characters: mandibles of ordinary form, scutellum without a row of foveae posteriorly, marginal vein very long, notauli slightly divergent posteriorly. Following Nixon’s (1957) key to male species of Cinetus, Cinetus breviscapus keys out near C. aletes Nixon, 1957 because of its scape that is shorter than F1 but differs in having the first flagellomere less distinctly longer than the scape (ratio scape length/F1 length: 1.2 vs 1.43; Nixon 1957), the petiole longer (three times as long as wide vs “about two and a half times as long as wide”) and being bigger (body length ca 3.6 mm vs ca 2.2 mm). In Baltic amber, Cinetus breviscapus sp. nov. is considered as separate from Cinetus inclusus Maneval, 1938 and Cinetus balticus Szabó & Oehlke, 1986 because it clearly does not fit with their descriptions. The petiole of C. balticus is longer than that of C. breviscapus (ratio length/middle height: 4 vs 2.8) and the fore wing venation is different (C. breviscapus has a longer marginal vein, a longer radial cell, the postmarginal vein does not extend beyond the radial cell and Rs is conspicuous for almost all its length). Cinetus inclusus has a shorter petiole (ratio length/middle height: 1.5) and the scape as long as pedicel, F1 and half of F2 combined, unlike C. breviscapus whose scape is shorter than flagellomere 1.

A new species of the parasitic wasp Coptera Say was previously distinguished from other species via correspondence between ecological (host) differences and DNA barcodes. A description and figures for Coptera tonicsp. nov., along with revisions to existing keys that allow it to be distinguished from other Nearctic species without the aid of molecular characters, is provided in this work.

International audience; The fossil diversity of Diapriidae in Baltic amber, dated Upper Eocene, has been poorly investigated. However, some studies suggest that this family was already diversified at this time. This is supported by our present study of the Baltic amber collection of the Natural History Museum of Denmark, from which we describe and figure ten new species belonging to the subfamilies Belytinae: Belyta knudhoejgaardi sp. nov., Cinetus breviscapus sp. nov., Cinetus elongatus sp. nov., Pantoclis globosa sp. nov., Pantolyta augustinusii sp. nov., Pantolyta chemyrevae sp. nov., Pantolyta similis sp. nov.; and Diapriinae: Basalys villumi sp. nov., Doliopria baltica sp. nov. and Spilomicrus succinalis sp. nov. The diversity of extant genera observed leads us to propose an origin in the early Cenozoic for these taxa. The fossil record of the Diapriidae in Baltic amber is also summarized.

All trochantelli present. Tegula, if present, covering lateral subapical lobe of humeral complex of fore wing base only partly. Fore wing, if present, with venation distinctly exceeding basal half of wing length (stigmal vein almost perpendicular to marginal vein, postmarginal vein present). Hind wing, if present, without closed basal cell. Median and lateral grooves present on T2 and S2; S2 without setose lines. S2 without basal cushion of setae; last sternite (S6) of female equal to or shorter than S3���S5 sternites combined. Remarks. The examined external morphological features and DNA sequence data support the allospecificity of Idiotypa maritima (Haliday) and I. mariae Gregor. Both species are widely distributed in Palaearctic from West Europe to Japan. Examination of the type material, the lectotype of I. nigriceps Kieffer, 1909 (the same specimen also the lectotype of I. nigriceps Kieffer, 1911), the lectotype of I. rufiventris (Thomson), and the lectotype of I. maritima (Haliday), clearly shows that these names are synonyms. The species Eunuchopria nitens Szab��, 1961, originally described in the monotypic genus Eunuchopria (Szab��, 1961), appears at first sight very different from Idiotypa, most noticeably by its aptery in both sexes, lack of ocelli, notauli, tegulae, axillae and axillar depressions; scutellum only visible as narrow transverse sclerite with only scutoscutellar sulcus between it and mesoscutum. However this is an expression of a common suite of reduction characters associated with extreme wing reduction and fossorial habits, which appears to have arisen commonly in several unrelated genera of diapriines. Similar extreme examples can be found in some undescribed species of Idiotypa from Chile and Argentina (Masner & Garcia, 2002), Spilomicrus myrmecophilus Nixon (females) and Platymischus dilatatus Westwood (both sexes). If these particular reductions are discounted the remaining features of E. nitens correspond well with diagnosis of the genus Idiotypa. We therefore consider E. nitens is simply a highly derived species of Idiotypa and Eunuchopria Szab��, 1961 is therefore a junior synonym of Idiotypa F��rster, 1856. Unfortunately the diagnostic characters of the species of Idiotypa are not universal in all parts of the Palaearctic region. The key below works well for the fauna of Europe (including the European part of Russia), Siberia and Russian Far East. While antennal characters of female I. maritima and I. mariae are difficult to appreciate, in combination with characters of the mesopleural sculpture and body colour, they can be used to make reliable determinations, however in Japan no combination of characters is consistent for species recognition., Published as part of Chemyreva, Vasilisa G., Notton, David G. & Zald��var-River��n, Alejandro, 2021, Revision of Palaearctic Idiotypa (Hymenoptera, Diapriidae, Diapriinae, Spilomicrini), pp. 127-144 in Zootaxa 4966 (2) on pages 129-130, DOI: 10.11646/zootaxa.4966.2.2, http://zenodo.org/record/4736399, {"references":["Ruthe, J.

A revision of the Palaearctic species of the genus Idiotypa Förster is provided. The genus Eunuchopria Szabó, 1961 is a junior synonym of Idiotypa Förster, 1856 syn. n. and the new combination Idiotypa nitens (Szabó, 1961) comb. n., is established. Dublicate original spellings I. marii and I. mariae are resolved by first reviser action; I. mariae is now the correct original spelling. Lectotypes are designated for Idiotypa mariae and I. maritima. New synonymy is proposed: I. maritima (Haliday, 1833) = I. rufiventris (Thomson, 1858) syn. n.; = I. nigriceps Kieffer, 1909 syn. n.; = I. nigriceps Kieffer, 1911 syn. n. The three valid species I. mariae Gregor, 1939, I. maritima (Haliday, 1833) and I. nitens (Szabó, 1961) are redescribed, illustrated and keyed.

Trichopria anastrephae Lima, 1940 (Figs 1, 2, 16) Diagnosis. Body dark-brown to black, surface mostly smooth and polished except petiole. Fore wing fully developed, without closed cells; with complete, short, subcostal vein (=submarginal vein), ending in a short marginal vein (genus Trichopria). Female antennae 12-segmented, with 3-segmented clava; male antennae 14-segmented; flagellomeres long and pedunculate, swollen apically with long setae. Scutellum smooth, median carina absent; scutellar sulcus smooth and shallow. Body length 1.8���2.0 mm. Considering the Neotropical fauna, Tr. anastrephae is similar to Trichopria peraffinis (Ashmead), which is a much smaller species (~1.0 mm long), and presents a small pit on scutellum anteriorly (absent in Tr. anastrephae). Taxonomy. Trichopria is one of the largest genera in Diapriidae, and no revision including the Neotropical fauna has been published, making identification to species level difficult. For instance, there are at least two unidentified species of Trichopria that parasitize species of Anastrepha in the New World (USA and Costa Rica) (Ovruski et al. 2000). Of the 12 species of Trichopria in Brazil (Margar��a 2020), nine can be keyed out using Kieffer���s (1910; 1916) identification keys in combination with original descriptions (Fouts 1926) or recent diagnosis (Notton 2014). Trichopria catarinensis Ferri��re is discarded because of its specialized biology, as parasitoid on Ecitonini (Hymenoptera, Formicidae). The remaining species, Trichopria lamellifera Ogloblin could also be discarded based on host association with Micropezidae (Diptera, Nerioidea), and morphological differences such as the length of antennomeres and its setae in males being much longer in T. anastrephae (antennomere 4 ~ 200 ��m and longest setae ~ 300 ��m) than in T. lamellifera (91 ��m and 98 ��m respectively), and females with much larger compound eyes (eye diameter ~5x longer than malar space in T. anastrephae compared to ~2.5x in T. lamellifera) (Ogloblin 1934). Trichopria is a diverse genus, with possibly a high number of undescribed species in the neotropics (Masner & Garc��a 2002). Therefore, caution is advised when using the identification key presented below. A revision of the genus is badly needed, for the Neotropical region. Biology. Trichopria anastrephae is an endoparasitoid koinobiont on pupae of Tephritidae and less frequently on Drosophilidae, for example Drosophila suzukii (Matsumura) (Yoder 2007). Known Tephritidae hosts are A. serpentina and A. fraterculus in Brazil (Lima 1940 and Aguiar-Menezes et al. 2001, respectively) and Ce. capitata in Argentina (Turica & Mallo 1961). Biological control. The potential of Tr. anastrephae as a biological agent has not been investigated in detail, although it is likely to be an important natural enemy of tephritids in Brazil, being the most common parasitoid species in star fruits (Silva et al. 2003).

Coptera haywardi Loi��cono, 1981 (Fig. 17) Diagnosis. Black with reddish-brown legs; head in dorsal view nearly as wide as long, vertex and occipital margin marked with large punctures; fore wing without distinct veins, but with longitudinal fold line, ending apically in a distinct notch in both sexes; metasomal petiole with complete median carina. This species is similar to Coptera pomonellae Muesebeck, differing mainly in the proportion between the eye and the malar space (larger in Co. pomonellae) and the complete median carina on the petiole (incomplete in Co. pomonellae). For the Neotropical species, Co. haywardi resembles Coptera sexpunctata (Ashmead), from which it can be distinguished by the smaller length/width ratio of head and petiole (Loi��cono 1981). Taxonomy. In the Neotropics, three species are known, Coptera brevipes (Kieffer), Co. haywardi and Co. sexpunctata (Johnson 1992; Notton 2014). The only key including Neotropical species was published more than a century ago (Kieffer 1916), species identification is therefore problematic, and the revision of Nearctic species by Muesebeck (1980) is helpful to some extent. In addition to those keys, a detailed, illustrated description is available for Co. haywardi, which allows comparison with reared material and more reliable identification (Loi��cono 1981). The Neotropical fauna is in urgent need of revision, and molecular characterization of the species seems to be important, since cryptic species have already been identified in this genus (Forbes et al. 2012). Biology. Endoparasitod koinobiont on pupae of tephritids (Sivinski et al. 1998), such as A. fraterculus, A. schultzi Blanchard (Loi��cono 1981) and A. ludens (Loew), infesting citrus (L��pez 1996); A. serpentina and A. striata Schiner in Venezuela (Garc��a & Montilla 2001); and A. fraterculus and A. sororcula in Brazil (Aguiar-Menezes et al. 2003) (Table 1). In the laboratory, Co. haywardi has been reared from A. obliqua (Garc��a & Montilla 2001), A suspensa (Loew, 1862), A. ludens, A. curvicauda (Gerstaecker) (as Toxotrypana curvicauda) and Ce. Capitata (Sivinski 1998). Biological control. This species has been considered for augmentative biological control programs because it possesses suitable biological traits, most importantly its specificity for fruit-infesting tephritids (Sivinski et al. 1998; Baeza-Larios et al. 2002).

Family Diapriidae (Hymenoptera, Diaprioidea) This family comprises about 2,300 species in 197 genera (Johnson 1992; Arias 2003). Most of them are pupal parasitoids on dipterans and are frequently associated with fungi (Masner 2006). Diapriidae is subdivided into four subfamilies. The two species (Co. haywardi and Tr. anastrephae) that are parasitoids of fruit-infesting tephritids in Brazil belong to the subfamily Diapriinae. An illustrated key to genera of the New World Diapriinae, based mostly on Masner & Garc��a (2002), is available online (Yoder et al. 2007). Both the genera Coptera and Trichopria are highly speciose, and a revision of the Neotropical fauna is necessary (Ovruski et al. 2000). Within the parasitoid species treated here, the Diapriinae are exceptional in their parasitism strategy, because, as opposed to most pupal parasitoids, they are endophagous and, in the few studies observing oviposition stage, allow further development of their hosts (i.e. koinobionts) (Sivinski et al. 1998, Masner 2006). These parasitoids prefer young pupae and are subject to most of the same physiological constraints as other koinobionts, because the pupa is not permanently paralyzed but continues to develop for some time before the parasitoid finally kills it (Sivinski et al. 1998). Most species of Diapriinae recorded on fruit-flies are stenophagous, specialists on species of a single family of Diptera (Ovrurski et al. 2000; Sivinski & Aluja 2012). There is evidence that some species of Coptera could be oligophagous, or even monophagous, using one or a very few species of Rhagoletis as hosts (Forbes et al. 2012). The foraging strategy of pupal parasitoids (i.e., searching and ovipositing in puparia in the soil) is complementary to that of the larval parasitoids, and an interesting trait for biological control when allied with a narrow host range (e.g. Wang et al. 2016), especially when the prey larvae in the fruit are nearly inaccessible to larval parasitoids., Published as part of Shimbori, Eduardo Mitio, Costa, Valmir Antonio & Zucchi, Roberto Antonio, 2020, Annotated checklist and illustrated key to parasitoids (Hymenoptera: Diapriidae Eulophidae and Pteromalidae) of fruit flies (Diptera, Tephritidae) in Brazil, pp. 53-70 in Zootaxa 4858 (1) on page 57, DOI: 10.11646/zootaxa.4858.1.3, http://zenodo.org/record/4411551, {"references":["Johnson, N.

The hymenopteran parasitoids of pest species of Tephritidae in Brazil are best known by their most prominent species, members of Braconidae and Figitidae. Species in the less-studied families Diapriidae, Eulophidae and Pteromalidae, which are mostly pupal parasitoids, have been largely neglected and the literature on these groups is sparse and scattered. Therefore, their importance as natural enemies of fruit flies is likely underestimated. Here, we present a parasitoid-host-plant checklist of all diapriids, eulophids and pteromalids that parasitize fruit flies of economic importance in Brazil, namely Anastrepha species and Ceratitis capitata. A compilation of information of the seven species of these parasitoids occurring in Brazil—Coptera haywardi Loiácono and Trichopria anastrephae Lima (Diapriidae), Tetrastichus giffardianus Silvestri (Eulophidae), Pachycrepoideus vindemmiae (Rondani), Spalangia endius Walker, S. gemina Bouček and S. simplex Perkins (Pteromalidae)—including their taxonomic status, general biology, and potential as biocontrol agents, is presented. Additionally, we provide an illustrated key to species, aiming to highlight key morphological features and facilitate identification at species level, stimulating future research on these groups.

The family Ismaridae Thomson, 1858 is reported from the Afrotropical region for the first time. A total of 15 species are recognised, 14 of which are described as new: Ismarusafricanussp. n. from Cameroon, Kenya, Malawi, South Africa; I.apertussp. n. from Kenya; I.bicolorsp. n. from Cameroon, Kenya; I.goodrichisp. n. from Kenya; I.kakamegensissp. n. from Kenya; I.kenyensissp. n. from Kenya; I.laevigatussp. n. from South Africa; I.madagascariensissp. n. from Madagascar; I.minutussp. n. from Kenya, Malawi, Zimbabwe; I.nigrofasciatussp. n. from Malawi, Uganda; I.notaulicussp. n. from Kenya; I.rawlinsisp. n. from Kenya, Malawi; I.steinerisp. n. from Madagascar; I.watshamisp. n. from Botswana, Malawi, South Africa, Zimbabwe. Ismarushalidayi Förster is reported for continental Africa from South Africa (new record). We provide an identification key to all species in Afrotropical region.

A new species of the genus Monelata Förster, 1856, Monelata truncata sp. n., is described and illustrated from Yunnan Province, China. This is the third Oriental species assigned to this genus. A key to Oriental species of the genus is provided.

Ismarus similis Kim, Notton & Lee sp. nov. urn:lsid:zoobank.org:act:D6A239E6-659A-44B5-9C36-757819D3A276 Fig. 6 Diagnosis In the form of the mesopleuron with its continuous zone of sculpture, Ismarus similis sp. nov. is similar to I. flavicornis. The main difference between these two species (females only) is the mesopleural sculpture, antennal colour and length of median longitudinal furrow on T2: mesopleuron with longitudinal wrinkles, antenna uniformly bright yellowish and T2 with median furrow extending to ¾ of segment in I. flavicornis; mesopleuron with deep punctures or irregular short wrinkles, antenna not uniformly yellowish and T2 with median furrow not exceeding basal half of segment in I. similis sp. nov. Etymology The specific epithet similis is derived from the Latin adjective, meaning similar. Type material (5 ♀♀) Holotype UNITED KINGDOM: ♀, Beds, Flitwick Moor, on Lonicera, 26 Jun. 1984, V.H.

However, Chambers (1981: as I. halidayi), but not Chambers (1955), which is in fact I. similis sp. nov., see below. Notes Kolyada & Chemyreva (2016) incorrectly state that Entomia campanulata is a nomen oblitum, however no action has been taken under Article 23.9.2 (ICZN 1999) to reverse the precedence with respect to I. halidayi so it cannot be a nomen oblitum. We follow Masner (1976) who doubtfully included in it synonymy with Ismarus halidayi and we consider that the interpretation of the species is doubtful and so the synonymy is also doubtful, and it is therefore a nomen dubium, i.e., although it is the older name, it is not certainly the valid name for the species referred to here as I. halidayi., Published as part of Kim, Chang-Jun, Notton, David G., ��degaard, Frode & Lee, Jong-Wook, 2018, Review of the Palaearctic species of Ismaridae Thomson, 1858 (Hymenoptera: Diaprioidea), pp. 1-38 in European Journal of Taxonomy 417 on pages 21-25, DOI: 10.5852/ejt.2018.417, http://zenodo.org/record/1211284, {"references":["ForsterA. 1850.

A review of the eight Palaearctic species of the genus Paramesius Westwood is provided, four of which are described and illustrated: P. primorus Chemyreva et Kolyada, sp. nov. (Russia: Primorsky Territory), P. janmaceki Chemyreva et Kolyada, sp. nov. (Russia: Primorsky Territory, Kuril Islands: Kunashir, Shikotan), P. ocampus Chemyreva et Kolyada, sp. nov. (Russia: Primorsky Territory, Sakhalin), and P. spiracularis Chemyreva et Kolyada, sp. nov. (Russia: Primorsky Territory, Khabarovsk Territory, Kuril Islands: Kunashir). New synonyms are proposed (valid name is the first): P. brachypterus Thomson, 1859 = P. spinosus Kieffer, 1911, syn. nov.; P. crassicornis Thomson, 1859 = P. dolosus Kieffer, 1911, syn. nov. = Spilomicrus kaszabi Szabo, 1977, syn. nov.; P. rufipes (Fonscolombe), 1832 = Spilomicrus striatifoveatus Szabo, 1960, syn. nov. All known Palaearctic species of Paramesius are keyed.

The name of this species is an arbitrary euphonious combination of letters, with no special meaning., Published as part of Chemyreva, Vasilisa G. & Kolyada, Victor A., 2018, Review of the genus Paramesius Westwood, 1832 (Hymenoptera: Diapriidae, Spilomicrini) from Russia, with description of four new species, pp. 453-472 in Zootaxa 4524 (4) on pages 462-464, DOI: 10.11646/zootaxa.4524.4.3, http://zenodo.org/record/2610662

Genus Paramesius Westwood, 1832 Paramesius Westwood, 1832: 129. Aparamesius Kieffer, 1913: 436. Synonymized by Masner & Muesebeck in Krombein & Burks (1967). Type species Paramesius rufipes Westwood, 1832, by monotypy (secondary homonym of Teleas rufipes Fonscolombe, 1832) = Paramesius belytoides Marshall, 1867 (suggested here). For the diagnosis of the genus, see Macek (2001) and Masner & Garc��a (2002). Taxonomic remark. The type species name P. rufipes Westwood was preoccupied by P. rufipes (Fonscolombe, 1832), the description of which had been published two months earlier (Fergusson, 1977). Dessart (1966) defined P. rufipes (Fonscolombe, 1832) as a senior name to P. elongatus Thomson, 1859, and this synonymy is confirmed here. Fergusson (1977) replaced the name P. rufipes Westwood (as a junior homonym) with P. westwoodi Fergusson, 1977. However, Macek (2001) suggested using the names P. rufipes Westwood and P. elongatus Thomson ���because P. rufipes Westwood is the type species of the genus Paramesius with type specimen preserved in OXUM, in contrast to obscure Paramesius (= Teleas) rufipes (Fonscolombe, 1832), the type of which is lost��� (Macek, 2001). This proposition contradicts to the ICZN (1999), and the type Paramesius (= Teleas) rufipes (Fonscolombe, 1832) is actually kept at MNHN (Paris, France) (Notton, 2004)., Published as part of Chemyreva, Vasilisa G. & Kolyada, Victor A., 2018, Review of the genus Paramesius Westwood, 1832 (Hymenoptera: Diapriidae, Spilomicrini) from Russia, with description of four new species, pp. 453-472 in Zootaxa 4524 (4) on page 454, DOI: 10.11646/zootaxa.4524.4.3, http://zenodo.org/record/2610662, {"references":["Westwood, J.
