9D658241FFD4FFFE61AE16C259F9892D.taxon	diagnosis	Diagnosis. Face without subantennal grooves (Figs 24, 33, 58, 117). Female antenna with funicle 8 - segmented and clava entire, the latter usually with 7 mps, but sometimes with 8 mps; male antenna with flagellum 11 - segmented. Pronotum entire, with usually a short, narrow collar. Prosternum divided mediolongitudinally (Fig. 68). Mesoscutum and scutellum at least partially with reticulate sculpture. Propodeum with a diamond-like pattern of distinct carinae forming five areoles [normally a median pentagonal areole, formed by a transverse carina at posterior margin of the propodeum and two, angled, sublateral carinae that usually meet medially, often at some distance from posterior margin of the dorsellum (e. g., Figs 23, 29); the areole is usually connected by a longitudinal median carina (of varying length depending on the species) that extends from its anterodorsal apex to the posterior margin of the dorsellum; the median areole is bordered on each side by a larger areole anterolaterally and a smaller areole posterolaterally; these, in turn, are bordered sublaterally by stronger, fairly straight lateral carinae extending from the carina surrounding the metacoxal foramen to or almost to the posterior margin of the dorsellum (e. g., Figs 10, 11)]. Forewing disc generally densely setose behind and beyond marginal vein; venation about one-third length of forewing (except in brachypterous females of O. hemipterus Haliday and two undescribed species from the Nearctic region); hypochaeta originating on membrane at anterior margin of forewing just above base of marginal vein, next to proximal macrochaeta. Tarsi 5 - segmented. Petiole at least 1.8 x as long as wide. In lateral view, first gastral tergum (= second metasomal tergum) usually at least as long as remaining gastral terga. Ovipositor usually at most a little exserted beyond apex of gaster but markedly exserted in two Nearctic species. Male genitalia with phallobase long, tubular. Classification. Ooctonus is a relatively easily genus to recognize, so any generic key to the Mymaridae may be used to identify it: Annecke & Doutt (1961) for the world genera, Yoshimoto (1990) for the New World genera, Huber (1997) for the Nearctic genera, and Triapitsyn & Huber (2000) for the Palaearctic genera. It is most similar to Boudiennyia Girault, its sister genus from Australia, which has a different arrangement of carinae on the propodeum, with a distinct transverse carina joining the longitudinal submedian carinae (Lin et al. 2007), and the venation about half-length of the forewing. The place of Ooctonus within the higher hierarchy of Mymaridae and its relationships with other genera were discussed by Schauff (1984), who placed it in the cladogram (together with Gonatocerus) next to the Alaptus group and other genera with 5 - segmented tarsi. Viggiani (1989) placed Ooctonus in Ooctonini Ashmead (Mymarinae) based solely on the external male genitalic characters. Huber (2002) justifiably placed Ooctonus in the same clade with Boudiennyia. Lin et al. (2007) placed Ooctonus and Boudiennyia in the Ooctonus group of genera and indicated their likely relationship to the Polynema group of genera. I agree with their preliminary conclusions, although having supporting evidence based on molecular data would be helpful. Because the existing higher classifications of Mymaridae are not natural, the proper placement of Ooctonus within the family cannot yet be determined confidently.	en	Triapitsyn, Serguei V.

9D658241FFD4FFFE61AE16C259F9892D.taxon	biology_ecology	Host associations. Biology of members of Ooctonus is practically unknown except for the following, more or less reliable, host associations. Ooctonus orientalis Doutt was reared in Japan from eggs of the leafhoppers (Hemiptera: Cicadellidae) Cicadella viridis (Linnaeus) (Doutt 1961) [as Tettigella viridis (Linnaeus)] and Nephotettix cincticeps (Uhler) (Sahad 1982). Ooctonus notatus Walker was recorded [as O. heterotomus Foerster] by Bakkendorf (1934) from eggs of an unknown “? hemipterous ” insect in Denmark; Bakkendorf also studied the preimaginal development and other aspects of the biology of O. notatus. Bakkendorf (1934) also mentioned an Ooctonus sp. from Denmark as a possible egg parasitoid of Aphrodes sp. [as Acocephalus sp.] (Cicadellidae). In the USA, several species of Ooctonus were reared from eggs of Aphrophoridae (Hemiptera) [sometimes included in Cercopidae]: O. aphrophorae Milliron from Aphrophora saratogensis (Fitch) (Milliron 1947), and O. vulgatus Haliday [as O. americanus Girault], as well as O. sp. and O. “ n. sp. ” from Philaenus spumarius (Linnaeus) (Weaver & King 1954) [as P. leucophthalmus (Linnaeus)]. The reported possible associations of the Nearctic species O. quadricarinatus Girault with Pityogenes hopkinsi Swaine (Coleoptera: Curculionidae) (Girault 1916 b), and also of the Holarctic species O. vulgatus with Sciara analis Schiner (Diptera: Sciaridae) (Pricop 2009 a; but see comments by Viggiani & Jesu 1988) need verification – most likely they are erroneous.	en	Triapitsyn, Serguei V.

9D658241FFD4FFFE61AE16C259F9892D.taxon	discussion	Remarks. The Australian species that had been described originally in Ooctonus were transferred to Gonatocerus by Lin et al. (2007). From the original description and illustrations of Ooctonus sevae Risbec from Madagascar (Risbec 1955), it is clear that this species also belongs in Gonatocerus, apparently in the subgenus G. (Lymaenon Walker) as defined by Triapitsyn et al. (2010). This is based on examination of the following specimens from Madagascar which seem to be conspecific with this very distinctive, peculiar Risbec’s species: FIANARANTSOA, Ranomafana, JIRAMA water works, 21 ° 14.91 ’ S 47 ° 27.13 ’ E, 690 m, 16. x – 8. xi. 2001, R. Harin’Hala, MT (MA- 02 - 09 D- 01) [1 ♀, CAS]; TOLIARA, Fôret Classée d’Analavelona, 29.2 km 343 ° NNW of Mahaboboka, 22 ° 40 ° 30 ’’ S 44 ° 11 ’ 24 ’’ E, 1100 m, 18 – 22. ii. 2003, B. Fisher, T. Griswold, YPT in montagne rainforest (BLF 7822) [1 ♀, 1 ♂, CAS]. Consequently, O. sevae is transferred here to Gonatocerus as G. (Lymaenon) sevae (Risbec), comb. n. This species, which has F 5 and F 6 of the female antenna white (Fig. 7), a very long petiole and the forewing disc bare behind the entire venation, is very unusual for G. (Lymaenon), where it is tentatively placed based mainly on the structure of its mesosoma (Fig. 8): the dorsellum is strap-like, and the lateral lobes of the pronotum are separated by apparently a lightly sclerotized, although unusually very narrow, median area (so that without a closer look, the pronotum superficially seems to be 2 - lobed). Its habitus is thus superficially very similar to that of some New World species from the morrilli subgroup of the ater species group of G. (Cosmocomoidea Howard), as defined by Triapitsyn et al. (2010), such as some members of G. (Cosmocomoidea) morrilli (Howard) complex, which also have a mostly light brown body, F 5 and F 6 of the female antenna white, a long petiole, and no or very few setae behind the marginal and stigmal veins on the forewing disc.	en	Triapitsyn, Serguei V.

Head and mesosoma very dark brown or black except eyes and ocelli pale or dirty pink; petiole yellowish or yellowish brown; gaster brown to dark brown; radicle light brown, the rest of scape and pedicel brown, and flagellum dark brown; legs yellowish brown except distal tarsomeres brown. Head with more or less defined reticulate sculpture. Antenna (Fig. 9) shorter than body, with radicle 0.2 – 0.26 x length of scape, remainder of scape 4.1 – 5.6 x as long as wide, a little wider medially than basally or apically, longitudinally striate; pedicel much longer than each of F 1 – F 6 and a little longer than F 7 or F 8; all funicle segments longer than wide, F 1 – F 6 more or less subequal in length and without mps, F 7 and F 8 notably longer and wider than preceding funicle segments, each with 2 mps; clava pointed in dorsal view and oval in lateral view, 2.4 – 3.0 x as long as wide, shorter than scape plus radicle, about as long or slightly shorter than combined length of F 5 – F 8 and about as long or slightly longer than combined length of F 1 – F 5, with 7 mps. Entire mesosoma (Fig. 10) with strong reticulate sculpture; propodeum (Fig. 11) without median carina, the median areole thus very large, narrowing and extending to anterior margin of propodeum, lateral carinae subparallel, extending to anterior margin of propodeum. In brachypterous specimens, wings variably abbreviated, extending from just beyond mesosoma to about two thirds length of gaster according to Hincks (1952) [in the lectotype, forewing extending to about two thirds length of gaster]; in most brachypterous specimens examined, forewing extending to about one third length of gaster, with disc reduced just beyond apex of venation and with a strong brownish tinge (Fig. 12); hind wing with disc reduced at apex of venation and with a strong brownish tinge (Fig. 13). In macropterous specimens, forewing (Fig. 14) extending beyond apex of gaster, 3.3 – 3.5 x as long as wide; disc with a light to strong brownish tinge throughout, densely setose except bare behind base of submarginal vein, rounded apically; longest marginal seta 0.26 – 0.37 x greatest width of wing. Hind wing (Fig. 14) 17 – 18 x as long as wide; disc with a slight brownish tinge and setose throughout except less setose behind apex of venation; longest marginal seta 2.2 – 2.4 x greatest width of wing.

Head and mesosoma dark brown or black except eyes and ocelli pale or dirty pink; petiole yellowish or yellowish brown; gaster usually dark brown but sometimes somewhat lighter (brown); scape and pedicel mostly light brown, flagellum dark brown (F 1 a little lighter); legs yellowish to light brown. Head (Fig. 24) with mostly weak sculpture on vertex and most of face. Antenna (Fig. 21) long and slender, with radicle a little more than 0.2 x length of scape, remainder of scape 4.5 – 4.6 x as long as wide, a little wider medially than basally or apically, longitudinally striate; pedicel usually at least slightly shorter than F 1; all funicle segments much longer than wide, F 1 – F 5 subequal in length, F 6 – F 8 a little shorter, mps on F 4 (usually 2, occasionally 0 or 1), F 5 (2), F 6 (usually 2, rarely 0 or 1), F 7 (2), F 8 (2) [note that Hincks (1952), who had only dry-mounted specimens available to him, incorrectly stated (p. 155) in his redescription of O. insignis that “ … sensory ridges confined to [the antennal] segments 9, 10 and club ”]; clava 3.0 – 3.5 x as long as wide, almost as long as scape plus radicle, longer than combined length of F 6 – F 8 and about as long or a little longer than combined length of F 1 – F 3, with 8 mps.

9D658241FFCAFFEA61AE15C05ABD8AF0.taxon	diagnosis	Diagnosis. Ooctonus insignis is characterized by presence of 8 mps on the clava of the female antenna. It is very similar to O. lokomotiv sp. n., the only other described Palaearctic species which has this feature but the latter bears a mps on F 3 of at least one of the female antennae (usually on both). The Nearctic species O. occidentalis Whittaker, described from Hollyburn, West Vancouver, British Columbia, Canada (Whittaker 1931), is superficially indistinguishable from O. insignis, but I refrain from proposing its formal synonymy under the latter name until a good-quality slide-mounted female specimen of O. occidentalis becomes available to check the number of mps on the clava.	en	Triapitsyn, Serguei V.

9D658241FFFEFFD061AE15E05ABD8BF4.taxon	description	Redescription. FEMALE (holotype of O. novickyi, and non-type specimens). Body length 1100 – 1240 µm [Soyka (1950) indicated the length of the holotype of O. novickyi as 1.67 mm but that is certainly incorrect because the length of its mesosoma and metasoma together is just 1045 µm; it is impossible to measure the length of the head because of the way it is mounted, but it would be safe to estimate (considering the average median head length in dorsal view in other conspecific specimens) that its total body length was a little more than 1.2 mm, perhaps 1210 – 1230 µm]. Head and mesosoma dark brown except eyes and ocelli pale or dirty pink; petiole yellowish to light brown; gaster mostly light brown (sometimes with a little darker on distal terga); scape and pedicel mostly light brown, flagellum brown to dark brown (F 1 a little lighter); coxae and trochanters yellowish, remainder of leg segments light brown except distal tarsomeres darker. Vertex and lower face with reticulate sculpture. Antenna (Figs 50, 52) with radicle 0.21 – 0.27 x length of scape, remainder of scape 4.2 – 4.8 x as long as wide, a little wider medially than basally or apically, longitudinally striate; pedicel longer than F 1; all funicle segments longer than wide, more or less subequal in length (F 1 the shortest and F 5 the longest funicle segment), F 1 – F 3 without mps, F 4 – F 8 each with 2 mps; clava 2.6 – 2.9 x as long as wide, a little shorter than scape plus radicle, about as long or slightly longer than combined length of F 6 – F 8 and a little longer than combined length of F 1 – F 3, with 7 mps. Mesosoma (Fig. 53) with pronotum weakly sculptured; mesoscutum and scutellum with reticulate sculpture (the cells smaller and less conspicuous on anterior scutellum; on posterior scutellum, the cells in the middle not as elongate as on the sides); metanotum smooth, with posterior margin broadly rounded; propodeum (Fig. 54) mostly smooth, with median carina shorter than median areole; lateral carinae subparallel, extending to anterior margin of propodeum. Forewing (Figs 51, 55) usually 3.2 – 3.4 x as long as wide (2.6 and 3.0 x as long as wide in two specimens from Gornotayozhnoye, Primorskiy Kray, Russia, respectively); disc with a very slight brownish tinge throughout (almost hyaline), densely setose but bare behind base of submarginal vein, rounded (in specimens with relatively narrower forewings) or very slightly truncate (in specimens with relatively wider forewings) apically; longest marginal seta 0.14 – 0.17 x greatest width of wing. Hind wing (Fig. 56) 15 – 18 x as long as wide; disc with a very slight brownish tinge (almost hyaline) and setose throughout (setae sparser behind apex of venation); longest marginal seta 1.8 – 2.3 x greatest width of wing. Coxae almost smooth (metacoxa very weakly sculptured); metafemur with weak sculpture. Gaster longer than mesosoma; petiole 2.9 – 3.3 x as long as wide, smooth, 1.0 – 1.2 x as long as metacoxa; ovipositor occupying 0.8 – 0.9 x length of gaster, at most slightly (by less than 0.1 x own length) exserted beyond apex of gaster, 1.1 – 1.2 x length of metatibia. Measurements (µm) of the holotype of O. novickyi. Mesosoma: 424; petiole: 124; gaster: 545; ovipositor: 424. Antenna: pedicel: 55; F 1: 42; F 2: 45; F 3: 45; F 4: 50; F 5: 54; F 6: 50; F 7: 48; F 8: 46; clava: 153. Forewing: 1033: 306; longest marginal seta: 49. Hind wing: 770: 45; longest marginal seta: 81. Legs (given as coxa, femur, tibia, tarsus): fore: 106, 227, 239, 233; middle: 100, 236, 342, 245; hind: 136, 270, 397, 258. MALE.

9D658241FFFEFFD061AE15E05ABD8BF4.taxon	diagnosis	Diagnosis. Ooctonus novickyi, known from females only, can be confused with O. insignis Haliday, whose female antenna also usually has 2 mps on F 4 – F 8, but the pedicel of the latter is usually at least slightly shorter than F 1 and the clava bears 8 mps. The gaster of O. insignis is usually dark brown (but sometimes brown) whereas it is notably lighter (mostly light brown) in O. novickyi.	en	Triapitsyn, Serguei V.

9D658241FFF9FFD861AE12AF5E598EAD.taxon	diagnosis	Diagnosis. Among the Palaearctic species of Ooctonus, O. saturn sp. n. is most similar to O. vulgatus Haliday in having mps normally only on F 7 and F 8 of the female antenna, but in the latter the midlobe of mesoscutum lacks an incomplete median groove and the posterior scutellum is mostly smooth except for a weak sculpture at the lateral borders and sometimes also at the anterior margin. In O. saturn the lateral carinae on the propodeum are not parallel to the median carina, and each lateral carina is split anteriorly as a very short, Y-shaped carina that is relatively notably smaller than in O. orientalis Doutt.	en	Triapitsyn, Serguei V.

Ooctonus dovrensis Solem & Sveum: Holotype female [NTNU] in alcohol, labeled [the original labels were inside a glass vial with an aluminum screw-cap]: 1. “ Norway, STi: Oppdal, Kongsvoll Vestbekken v / 10 August 1978 coll. Per Sveum sub-alpine birch belt. ”; 2. “ Ooctonus dovrensis n. sp. det. J. O. Solem and Per Sveum Holotype (♀) ”; 3. “ 487 ”. 3 male paratypes [NTNU] in alcohol, labeled [the original labels were inside a glass vial with an aluminum screw-cap]: 1. “ STi: Oppdal, Kongsvoll, Vestbekk v / 10 August 1978 coll. P. Sveum sub-alpine birch forest ”; 2. “ Ooctonus dovrensis n. sp. det. J. O. Solem and P. Sveum Paratypes (♂♂) coll. # 488 ”. The holotype and the above-mentioned two paratypes were originally stored in alcohol so all are slightly faded. They were critically point dried at UCRC on 16. iv. 2008 and then point-mounted; the remaining paratypes [3 slide-mounted females, 9 slide-mounted males, and 8 males in alcohol (Solem & Sveum 1980)] were not examined (all in NTNU). One of the forewings from the holotype specimen was slide-mounted because it came off during the drying process. Ooctonus montanus Soyka: Holotype female [NHMW] on slide labeled: 1. “ Ooctonus montanus (Soyka) ♀ Type ”; 2. “ Type ”; 3. “ Riesengebirge ca. 1400 m [many illegible words follow, see Soyka (1950) for their likely interpretation] 28.9.1933 Stammer In Canadabalsam ”. Ooctonus polonicus Soyka: Holotype female [NHMW] on slide labeled: 1. “ Ooctonus polonicus ♀ ”; 2. “ Type ”; 3. “ Magura Worochta 20. VIII. 33, Novicky lg Magura Worochta In Canadab. 1941 ”. Ooctonus remonti Mathot: Holotype female [ISNB] on slide labeled: 1. “ Université de Louvain LAB. ENTOMOLOGIE Tervueren 4. VII. 45 Etang du Mérisier ”; 2. “ Université de Louvain LAB. ENTOMOLOGIE Ooctonus remonti DEB. TYPE ♀ ”. The holotype specimen is complete, poorly mounted laterally. Ooctonus sublaevis Foerster: Lectotype female [NHMW], here designated to avoid ambiguity of the status of the type specimens of this species, on slide (Fig. 81) labeled: 1. “ Ooctonus sublaevis Förster ♀ Soyka Canadab. 5 ”; 2. [red] “ Type ”; 3. “ O. sublaevis [in India ink, in A. Foerster’s handwriting] Förster, Type ”; 4. “ Aach. Förster ”; 5. “ Collect. G. Mayr ”. The lectotype specimen (Figs 82, 83) is in fair condition, mounted more or less dorsoventrally; flagella of both antennae are detached (one of them together with the pedicel). Foerster (1847) mentioned only one specimen of this species, which apparently (although that is not possible to know for sure) was later indicated by Soyka (1949) as a “ type ” and marked by him as such after he remounted it onto a slide from the original minuten pin. However, I found in NHMW three additional slides with 1 female and 2 males, labeled in W. Soyka’s handwriting as “ Ooctonus sublaevis Förster ” and “ Collect. G. Mayr Aachen, Förster Förster, Type in Canabab. ”. There is little doubt that these had been originally identified (correctly) by A. Foerster himself and were likely part of the original material of O. sublaevis (A. Foerster did not mark his type specimens and, furthermore, most of his specimens, collected by G. Mayr in the environs of Aachen, Germany, were labeled as “ Förster, Type ” regardless of their type status, if any); W. Soyka later remounted them from the minuten pins and copied the original labels. Thus, these three specimens are also considered to be the original syntypes and are designated here as paralectotypes. This seems to be a more reasonable approach than Soyka’s (1949) interpretation of just one of these specimens (the present lectotype female) as “ type ”. Material examined. AUSTRIA.

9D658241FFF2FFC261AE11105ABD8B60.taxon	diagnosis	Diagnosis. Ooctonus sublaevis is characterized by the following unique combination of features: F 1 – F 4 almost always without mps and F 5 – F 8 usually with 2 mps each; propodeum with median carina longer than or subequal in length to the median areole but often median carina incomplete, not extending to anterior margin of propodeum, or almost absent. Some large O. sublaevis may be confused with a few small specimens of O. insignis that lack mps on F 4 of the female antenna, but O. sublaevis has 7 mps on the clava and a different arrangement of the propodeal carinae (the median carina is very short in O. insignis); O. sublaevis differs from O. orientalis in lacking the broad Y-shaped anterior split of each of the lateral carinae on the propodeum.	en	Triapitsyn, Serguei V.

Ooctonus stammeri Soyka: Holotype female [NHMW] on slide labeled: 1. “ Ooctonus stammeri (Soyka) ♀ Type ”; 2. “ Type ”; 3. “ 46 Riesengebirge, Schlesien [several illegible words follow including “ auf Wiesen ”] 10. Aug. 1933 lg. Stammer 1300 m in Canadab. ”. Soyka (1949) mentioned a female “ Type ” and 5 female “ Cotypes ” of this species; it is obvious that the latter were meant as modern paratypes, and therefore the “ Type ” is considered to be the holotype. These 5 female paratypes (from the same habitat as the holotype) were not found in NHMW.

9D658241FFEBFFC961AE10D25FC28F25.taxon	description	Redescription. FEMALE (holotypes of the synonyms, and non-type specimens). Body length 750 – 1650 µm. Head and mesosoma very dark brown or black except eyes and ocelli pale or dirty pink; petiole yellowish or yellowish brown; gaster usually brown to dark brown but sometimes light brown (a little darker than legs); scape and pedicel mostly light brown, flagellum dark brown; legs yellowish brown except distal tarsomeres brown. Lower face with weak sculpture, vertex with stronger sculpture. Antenna (Fig. 106) slender, with radicle about 0.25 x length of scape, remainder of scape 4.2 – 5.2 x as long as wide, a little wider medially than basally or apically, longitudinally striate; pedicel usually about as long as F 1 or slightly longer, but occasionally (in large specimens) a little shorter than F 1; all funicle segments longer than wide, F 1 and F 2 more or less subequal in length and the longest funicle segments, F 3 a little shorter and wider, F 4 – F 6 shorter than F 3 or F 7 (F 6 the shortest funicle segment), F 1 – F 6 almost always without mps (very rarely [in one very large specimen from Mamontovka, Moscow Region, Russia] F 6 with 1 mps on one of the antennae), F 7 and F 8 notably wider than preceding funicle segments, almost always with 2 mps each (very rarely [in one specimen from Montpellier, France] F 8 with just 1 mps on one of the antennae); clava 2.5 – 3.0 x as long as wide, shorter than scape plus radicle, usually about as long as combined length of F 6 – F 8 but sometimes a little longer, and at least a little shorter than combined length of F 1 – F 3 (usually notably shorter), with 7 mps. Mesosoma (Fig. 107) with pronotum weakly sculptured; mesoscutum with strong reticulate sculpture; anterior scutellum with weak, inconspicuous sculpture, posterior scutellum (Figs 108, 111) mostly smooth except for a weak sculpture at lateral borders and sometimes also at anterior margin; metanotum smooth, with posterior margin slightly broadly rounded; propodeum (Figs 108, 111) mostly smooth, with median carina absent or very short (thus the median areole large, extending or almost extending to anterior margin of propodeum); lateral carinae subparallel, extending to anterior margin of propodeum. Forewing (Fig. 109) 2.5 – 3.9 x as long as wide (see “ Variation ” below); disc with a slight to strong brownish tinge throughout (more so as a sinuate, narrow, brownish strip behind venation, also extending beyond venation along posterior margin to a little more than half length of wing), densely setose but bare behind base of submarginal vein, truncate apically; longest marginal seta 0.12 – 0.31 x greatest width of wing. Hind wing (Fig. 110) 12 – 19 x as long as wide; disc with a slight brownish tinge and setose throughout (less so just behind apex of venation); longest marginal seta 1.3 – 2.4 x greatest width of wing. Pro- and mesocoxae smooth, metacoxa weakly sculptured. Gaster at least a little longer than mesosoma; petiole 1.8 – 3.1 x as long as wide, smooth, 0.9 – 1.2 x as long as metacoxa; ovipositor occupying 0.6 – 0.9 x length of gaster, a little exserted beyond apex of gaster (by at most 0.13 x own length), 1.0 – 1.3 x length of metatibia. MALE. Similar to female except for the normal sexually dimorphic features and the following [range of body length is difficult to assess because of the limited material at hand]. Antenna (Fig. 112) longer than body, with scape (including radicle) 6.0 – 7.1 x as long as wide, entire flagellum dark brown; forewing (Fig. 113) 2.9 – 3.0 x as long as wide; gaster shorter than in female, genitalia as in Fig. 114.	en	Triapitsyn, Serguei V.

9D658241FFEBFFC961AE10D25FC28F25.taxon	diagnosis	Diagnosis. Ooctonus vulgatus is characterized by the following unique combination of features: female antenna with mps almost always only on F 7 and F 8; posterior scutellum mostly smooth except for a weak, often inconspicuous sculpture at lateral borders and sometimes also at anterior margin; propodeum with median carina absent or very short (relatively longer in very large specimens), thus the median areole large, extending or almost extending to anterior margin of propodeum; petiole short, 0.9 – 1.2 x as long as metacoxa. Ooctonus vulgatus is very similar to the Nearctic species O. silvensis Girault (Girault 1916 a), which has F 2 of the female antenna notably shorter than F 1 and about as long or slightly shorter than F 3, and also generally darker legs, particularly meso- and metafemora and meso- and metatibiae.	en	Triapitsyn, Serguei V.

9D658241FFEBFFC961AE10D25FC28F25.taxon	description	Variation. The synonymy of O. askhamensis under O. vulgatus is not as clearcut as most other synonymies proposed here, because the only three examined specimens of this nominal species (the holotype, the female collected by W. Soyka on 4. ix. 1953 in Krössbach, Austria, and the female collected by me on 16. viii. 2003 in Mamontovka, Russia) have wider forewings (length: width ratio 2.5 – 2.7: 1) than for more typical females of O. vulgatus (length: width ratio 2.8 – 3.5: 1). I correlate this difference with body size of the specimens, the ones attributable to O. askhamensis being larger (body length 1.25 – 1.65 mm) than typical O. vulgatus (body length 0.75 – 1.2 mm). All other morphological features of O. askhamensis are identical to those of O. vulgatus, hence the synonymy. The forewing length: width ratio does not seem to be a reliable diagnostic character for differentiation of European species of Ooctonus. Very small specimens tend to have relatively narrower forewings, e. g., in the female (ca. 0.9 mm long) collected by V. V. Kostjukov on 19 – 20. viii. 2001 in Krasnodar, Russia, this ratio is about 3.5: 1, whereas very large specimens tend to have relatively wider forewings, e. g., in the female (1.65 mm long) from Krössbach that fits the description of O. askhamensis, this ratio is about 2.6: 1. In the 1.25 mm long, dry mounted holotype of O. askhamensis, the forewing length: width ratio is about 2.5: 1 (Hincks 1952). In an aberrant, small female specimen collected by J. T. Huber on 19 – 20. iv. 1978 in Montpellier, France, the forewing length: width ratio is about 3.9: 1.	en	Triapitsyn, Serguei V.

9D658241FF9CFFB161AE146F5AC58B94.taxon	description	Redescription. FEMALE (holotype). Length 1700 µm [erroneously indicated as 1.8 mm by Subba Rao (1989)]. Body (Fig. 135) almost entirely black except eyes and ocelli dirty pink and gaster dark brown to black; coxae black, remainder of leg segments and also scape and pedicel light brown (metatibia slightly darker distally); flagellum brown. All funicle segments much longer than wide and more or less subequal in length (distal ones a little shorter), F 1 notably longer than pedicel; mps apparently present on F 4 – F 8, at least (impossible to verify without slide-mounting an antenna). Mesosoma with pronotum weakly reticulate; mesoscutum and scutellum with reticulate sculpture (the cells larger on mesoscutum and posterior scutellum than on anterior scutellum, those on posterior scutellum more longitudinally elongate), midlobe of mesoscutum with a median groove about as wide posteriorly as width of a notaulus, anteriorly narrowing and almost extending to anterior margin of mesoscutum; metanotum strap-like, sculptured anteriorly; propodeum weakly, yet notably, sculptured, with median and lateral carinae parallel and a little longer than median areole. Forewing approximately 2.9 x as long as wide; disc with a slight brownish tinge throughout, densely setose but bare behind most of submarginal vein, with discal setae only just behind its apex along posterior margin of wing, slightly truncate apically. Metacoxa with strong reticulate sculpture. Petiole smooth, shining, much longer than metacoxa; gaster much shorter than mesosoma; ovipositor not exserted beyond apex of gaster. Description. MALE (paratype, previously undescribed, see “ Type material examined ” above and also “ Comments ” below). Similar to female except for the normal sexually dimorphic features.	en	Triapitsyn, Serguei V.

9D658241FF9CFFB161AE146F5AC58B94.taxon	diagnosis	Diagnosis. Ooctonus nigrotestaceus differs from all other known Oriental species of the genus that have the midlobe of mesoscutum mediolongitudinally divided by an almost complete median groove (at least 0.5 x length of mesoscutum), such as O. flavipodus Subba Rao, O. lapen sp. n., and O. sinensis Subba Rao, in having the combination of black metacoxae and the propodeum with median and lateral carinae long and parallel, and lateral carinae extending to the anterior margin of propodeum. In O. sinensis, which also has a black metacoxa, the lateral carinae on the propodeum are not parallel with the median carina and do not extend to the anterior margin of propodeum, and the petiole is longitudinally striate (smooth in O. nigrotestaceus).	en	Triapitsyn, Serguei V.

9D658241FF9AFFB461AE10D25A3F8B3C.taxon	description	Redescription. FEMALE (holotype). Length 2575 µm. Body (Fig. 136) almost entirely black except eyes and ocelli dirty pink and gaster dark brown to black; scape light brown, pedicel mostly brown, flagellum dark brown; coxae black, remainder of leg segments light brown to brown except metafemur and metatibia dark brown. Scape a little longer than clava, apical half or so of scape wider than its basal half. All funicle segments much longer than wide and more or less subequal in length (distal ones a little shorter), F 1 notably longer than pedicel; mps apparently present at least on F 4 – F 8 (impossible to verify without slide-mounting an antenna). Mesosoma (Fig. 137) with pronotum weakly reticulate; mesoscutum and scutellum with strong reticulate sculpture (the cells much larger on mesoscutum and posterior scutellum than on anterior scutellum, those on posterior scutellum more longitudinally elongate), midlobe of mesoscutum with a median groove about as wide posteriorly as width of a notaulus, anteriorly narrowing and almost extending to anterior margin of mesoscutum; metanotum sculptured basally, with posterior margin broadly rounded; propodeum strongly sculptured, with median carina long, and lateral carinae not parallel with median carina and not extending to anterior margin of propodeum. Forewing approximately 3.0 x as long as wide; disc with a slight brownish tinge throughout, densely setose but bare behind most of submarginal vein, with discal setae only just behind its apex along posterior margin of wing, slightly truncate apically. Pro- and mesocoxae smooth, metacoxa with strong reticulate sculpture, metafemur also reticulate but not as strongly as metacoxa. Petiole longitudinally striate, longer than metacoxa; gaster shorter than mesosoma; ovipositor not exserted beyond apex of gaster. MALE. Subba Rao (1989) indicated (p. 142) the following regarding the male paratype of his O. sinensis from above Sangu, Taplejung District, Mechi Zone, Nepal: “ Male: With some hesitation, I am designating this specimen as the male of this species. Although the specimen has been collected from Nepal, except for its slight colour pattern of the legs, I cannot find any other morphological difference either in the sculpture or in other characters described for the female ”. Subba Rao may be correct in his association of the two specimens, but in my opinion there is a greater likelihood that the male paratype and female holotype are not conspecific. As correctly noted by Subba Rao (1989) regarding their leg coloration, the metafemur of the female holotype is completely dark brown whereas the metafemur of the male paratype is mostly light brown (except partially brown to dark brown distally). One would expect that within the same species a female collected (in the northern hemisphere) at a lower latitude and elevation would not be darker than a male collected at a higher latitude and elevation, which is not the case for the two type specimens. There are also slight differences between the two specimens in the sculpture of the mesosoma (Figs 137 and 138, respectively), although generally they are indeed superficially quite similar (both are card-mounted, so some features are difficult to assess). Both specimens are quite large and of more or less similar size (body length of the male is about 2.8 mm). Until a male of O. sinensis is collected at the type locality in Hainan Island and compared with the paratype male from Nepal, the issue of their conspecificity will remain unresolved.	en	Triapitsyn, Serguei V.

Acknowledgments I thank Dominique Zimmermann and Herbert Zettel (International Research Institute of Entomology, NHMW) for inviting me to curate the Walter Soyka collection of microhymenoptera, for their kind assistance during my visit to Vienna, and also for the loan of specimens. My trip to Austria in June 2007 was very productive also largely due to collaboration of Csaba Thuróczy (Köszeg, Hungary). We shared the curation efforts of the NHMW collection of Mymaridae and also collected in the W. Soyka’s type locality in Hundsheim and other places in Lower Austria. C. Thuróczy kindly made available to me some of W. Soyka’s publications and also the digital photographs of the primary types of A. H. Haliday’s and F. Walker’s species of Ooctonus and some other mymarid genera in NTNU. John T. Huber (CNCI), Dmitri V. Logunov (MMUE), John S. Noyes and David Notton (BMNH), Torbjørn Ekrem (NTNU), Jerome Constant (ISNB), Steven L. Heydon (UCDC), Michael W. Gates (USNM), Jo Berry (NZAC), and Robert L. Zuparko (CAS and EMEC) arranged the loans of specimens from the respective collections. Marina V. Michailovskaya (Mountain-Taiga Station, Far Eastern Branch of the Russian Academy of Sciences, Gornotayozhnoye, Primorskiy krai, Russia), my mother Elisaveta Ya. Shouvakhina, and my father-in-law Mikhail E. Tretiakov collected many interesting mymarids in Russia and made them available for this study. Sister Antonia (Toni) Pietryga (Hundsheim, Austria) graciously showed Csaba Thuróczy and me Walter Soyka’s collecting and former study rooms in the priest’s house in Hundsheim. John T. Huber and Gary A. P. Gibson (CNCI) made many useful suggestions for improvement of the manuscript. Vladimir V. Berezovskiy and Jennifer Walker (UCRC) provided technical assistance.	en	Triapitsyn, Serguei V.
