Description. FEMALE. Body length 860–1220 µm (dry-mounted paratypes ). Head and mesosoma black, gaster mostly dark brown; scape and pedicel brown, flagellum brown to dark brown except F1 sometimes a little lighter, legs mostly brown to dark brown. Antenna ( Fig. 106 ) with radicle 0.32× total length of scape, rest of scape 3.0–3.3× as long as wide, weakly sculptured; pedicel much longer than F1; F1 and F2 shorter than following funicle segments, F4 from about as long as to notably longer than F3, F5–F8 more or less subequal in length and longer than F1–F4; mps on F4 (almost always 0, rarely 1 on one antenna), F5 (usually 2, occasionally 3 on one antenna), F6 (usually 2, occasionally 3, or, rarely, 1 on one antenna in small specimens), F7 (usually 2, sometimes 3), and F8 (usually 3 or 4 but sometimes 2 in small specimens or 5 in large specimens); clava usually with 11 or 12 mps but sometimes with only 10 mps in small specimens, 2.9–3.5× as long as wide, at least slightly shorter than combined length of F6–F8. Mesosoma ( Fig. 108 ). Propodeum ( Fig. 107 ) with submedian lines wide apart. Fore wing ( Fig. 109 ) 2.7– 3.1× as long as wide; longest marginal seta 0.23–0.26× maximum wing width; disc with a slight brownish tinge (often almost hyaline), bare behind submarginal vein and densely setose elsewhere except with a usually large and distinct bare area between marginal vein and cubital row of setae (a row of setae always present next to marginal vein and occasionally additional, sparse setae also present behind marginal vein so that the bare area sometimes less distinct). Hind wing 16–20× as long as wide; disc rather sparsely setose and almost hyaline; longest marginal seta 2.1–2.5× maximum wing width. Metasoma ( Fig. 108 ). Gaster longer than mesosoma. Petiole 1.9–2.5× as wide as long. Ovipositor occupying 0.7–0.9× length of gaster, barely exserted beyond its apex (by at most 0.07× own length); ovipositor length: mesotibia length ratio usually 1.5–1.7:1 but rarely about 2.0: 1 in a few specimens. Measurements (µm) of the holotype . Mesosoma 510; petiole 27; gaster 615; ovipositor 523. Antenna: radicle 73; rest of scape 158; pedicel 61; F1 33; F2 37; F3 45; F4 47; F5 80; F6 73; F7 82; F8 82; clava 215. Fore wing 1169:437; longest marginal seta 103. Hind wing 959:60; longest marginal seta 128. MALE. Body length 960–1155 µm (dry-mounted specimens before slide-mounting). Similar to female except for normal sexually dimorphic features and the following. Head and mesosoma black, gaster dark brown to black, antenna brown, legs mostly brown to dark brown. Antenna as in Fig. 110 , scape with cross-ridges. Wings ( Fig. 111 ) hyaline; fore wing 2.6–3.0× (usually 2.7–2.8×) as long as wide. Genitalia as in Fig. 112 . Diagnosis. Gonatocerus katraps does not resemble any European species of G. ( Lymaenon ) except perhaps G. acuminatus which has a much longer, distinctly exserted ovipositor. It is somewhat similar to G. ( Lymaenon ) bakrotus Mani & Saraswat from high elevation in northern India ( Mani & Saraswat 1973 ), and to the lesser extent, also to G. ( Lymaenon ) narayani (Subba Rao & Kaur) from Bangladesh , India , and Thailand ( Zeya & Hayat 1995 ; Zeya & Khan 2011 ). Gonatocerus katraps differs from G. bakrotus in having a distinct bare area on the fore wing disc between the marginal vein and the cubital row of setae ( Figs 109 , 111 ), and from G. narayani by the much darker body color. Etymology. The species name is an arbitrary combination of letters treated as a noun in apposition. Hosts. Unknown. FIGURES 106–109. Gonatocerus ( Lymaenon ) katraps Ƥ (paratypes, Gornotayozhnoye, Primorskiy kray, Russia): 106, antenna; 107, dorsellum and propodeum; 108, mesosoma and metasoma; 109, fore wing. Comments. The following two small female specimens most likely belong to G. katraps but are not included in the paratype series because they have relatively shorter F5–F8 of the antenna, a narrower fore wing (3.3–3.45× as long as wide), and a relatively shorter ovipositor (1.3–1.4× as long as mesotibia) than the typical G. katraps : RUSSIA .
