 Description. FEMALE. Body length 960–1220 µm (dry-mounted paratypes). Head and mesosoma dark brown to black, gaster brown to dark brown; antenna brown, legs mostly brown to dark brown.   
Antenna (Fig. 132) with radicle 0.34–0.36× total length of scape, rest of scape 2.8–3.3× as long as wide, almost smooth (slightly longitudinally striate); pedicel longer than F1; F1–F3 shorter than following funicle segments, F5 and F6 subequal in length and a little longer than F4, F7, or F8; mps on F4 (0 or 1), F5 (2), F6 (usually 2, rarely 3), F7 (2), and F8 (4 or 5); clava with 9 or 10 mps, 2.8–3.0× as long as wide, a little longer than combined length of F7 and F8.  
Mesosoma (Fig. 134). Propodeum (Fig. 133) with submedian lines wide apart. Fore wing (Fig. 135) 2.6– 2.9× as long as wide; longest marginal seta 0.23–0.25× maximum wing width; disc with a brownish tinge throughout, bare behind submarginal vein and setose elsewhere. Hind wing 16–17× as long as wide; disc rather densely setose and with a slight brownish tinge; longest marginal seta 1.9–2.3× maximum wing width.  
Metasoma (Fig. 134). Gaster notably longer than mesosoma. Petiole 2.7–3.2× as wide as long. Ovipositor long, occupying from 0.9× to usually entire length of gaster, markedly exserted beyond its apex (by 0.17–0.24× own length) posteriorly and occasionally slightly projecting anteriorly under petiole; ovipositor length: mesotibia length ratio 2.6–2.8:1.  
Measurements (µm) of the holotype. Mesosoma 474; petiole 27; gaster 769; ovipositor 843. Antenna: radicle 72; rest of scape 133; pedicel 60; F1 32; F2 33; F3 39; F4 66; F5 76; F6 77; F7 68; F8 67; clava 179. Fore wing 1125:424; longest marginal seta 97. Hind wing 922:58; longest marginal seta 121.  
MALE. Unknown.  
 Diagnosis. Gonatocerus kusaka is similar to G. acuminatus from which it differs by not having a bare area between the marginal vein and the cubital row of setae (Fig. 135). The antenna of G. kusaka often bears a mps on F4 whereas that of G. acuminatus does not. Also see the diagnosis of G. kum.   
 Etymology. The species name (a noun in apposition) means “one that bites” in Russian.   
 Hosts. Unknown.
