( Figs 129–131 View FIGURES 129 – 131 )
Type material. Holotype female [ CAS] on slide: RUSSIA. SAKHALINSKAYA OBLAST’ , Sakhalin Island (SE part), near Anna River mouth , 47°09.90’N 143°01.82’ E, 13.viii.2001, D.J. Bennett. GoogleMaps
Description. FEMALE. Head dark brown, mesosoma mostly brown to dark brown except mesoscutum and scutellum partially light brown, gaster brown except light brown basally; scape and pedicel mostly light brown with some brown, flagellum brown, legs light brown.
Antenna ( Fig. 129 View FIGURES 129 – 131 ) long, with radicle about 0.29× total length of scape, rest of scape about 4.5× as long as wide; pedicel longer than F1; F1 the shortest and F5 the longest among funicle segments (all notably longer than wide), F4 and F6 a little shorter than F5, F8 the broadest funicle segment; mps on F5 (1), F6 (2), F7 (2) and F8 (2); clava with 10 mps, 3.4× as long as wide, a little shorter than combined length of F6–F8.
Mesosoma ( Fig. 130 View FIGURES 129 – 131 ). Propodeum with submedian lines moderately close to each other. Fore wing ( Fig. 131 View FIGURES 129 – 131 ) 3.3× as long as wide; longest marginal seta about 0.3× maximum wing width; disc with a strong brownish tinge, mostly bare behind submarginal vein except for a few setae behind its apex and densely setose elsewhere. Hind wing ( Fig. 131 View FIGURES 129 – 131 ) narrow, 27× as long as wide; disc unevenly setose and with a strong brownish tinge; longest marginal seta 3.7× maximum wing width.
Metasoma ( Fig. 130 View FIGURES 129 – 131 ). Gaster notably longer than mesosoma. Petiole 1.8× as wide as long. Ovipositor occupying about 0.9× length of gaster, exserted strongly beyond its apex (by 0.35× own length); ovipositor length: mesotibia length ratio about 2.1:1. External plate of ovipositor with 4 distal setae, faintly sculptured in apical half.
Measurements (µm). Body (total length measured before slide-mounting) 1320; head (length measured before slide-mounting) 165; mesosoma 510; petiole 36; gaster 738; ovipositor 1045. Antenna: radicle 100; rest of scape 250; pedicel 81; F1 52; F2 87; F3 99; F4 112; F5 115; F6 109; F7 97; F8 85; clava 282. Fore wing 1648:504; longest marginal seta 150. Hind wing 1212:45; longest marginal seta 167.
MALE. Unknown.
Diagnosis. Gonatocerus kum is unique among Palaearctic species of the subgenus in having the ovipositor projecting beyond the apex of gaster by about 0.35× own length ( Fig. 130 View FIGURES 129 – 131 ). It differs from G. novickyi , which also has a markedly exserted ovipositor (although by at most 0.22× own length) in having a relatively wider (3.3× as long as wide) fore wing ( Fig. 131 View FIGURES 129 – 131 ) (at least 4.2× as long as wide in G. novickyi ) and the ovipositor about 2.1× as long as mesotibia (at least 2.6× as long as mesotibia in G. novickyi ). Gonatocerus kum differs from G. kusaka , which also has a strongly exserted ovipositor (although by at most 0.24× own length), in having only 2 mps on F8 (4 or 5 mps in G. kusaka ).
Etymology. The species name (a noun in apposition) stands for a godfather of one’s child in Russian.
Hosts. Unknown.
