Description. FEMALE. Body length 925–990 µm (dry-mounted paratypes). Head and mesosoma mostly dark brown, with a few yellow spots on mesosoma; gaster yellow (anterior half or so) and brown (posterior half or so); antenna brown, legs mostly brown to dark brown but with some yellow and light brown.

Antenna ( Fig. 81 View FIGURES 81 – 84 ) with radicle 0.35–0.38× total length of scape, rest of scape 3.1–3.5× as long as wide, with faint cross-ridges; pedicel longer than F1; F1 about as long as F2 and notably shorter than following funicle segments; F5 and F6 subequal in length, longer than F3 or F4 and slightly longer than F7 or F8; mps on F5 (usually 2, occasionally 1), F6 (2), F7 (2), and F8 (2); clava with 8 mps, 3.1–3.4× as long as wide, a little longer than combined length of F7 and F8.

Mesosoma ( Fig. 82 View FIGURES 81 – 84 ). Propodeum with submedian lines wide apart. Fore wing ( Fig. 83 View FIGURES 81 – 84 ) 2.7–2.9× as long as wide; longest marginal seta 0.21–0.29× maximum wing width; disc with a faint brownish tinge throughout, bare behind submarginal vein and setose elsewhere although relatively more sparsely behind marginal vein. Hind wing ( Fig. 84 View FIGURES 81 – 84 ) 17–20× as long as wide; disc rather densely setose apically, almost hyaline; longest marginal seta 2.1– 2.9× maximum wing width.

Metasoma ( Fig. 82 View FIGURES 81 – 84 ). Gaster longer than mesosoma. Petiole 1.8–1.9× as wide as long. Ovipositor occupying 0.8–0.9× length of gaster, at most barely exserted beyond its apex; ovipositor length: mesotibia length ratio 1.7–1.8:1.

Measurements (µm) of the holotype. Mesosoma 406; petiole 30; gaster 566; ovipositor 517. Antenna: radicle 73; rest of scape 136; pedicel 61; F1 30; F2 30; F3 42; F4 54; F5 67; F6 67; F7 65; F8 60; clava 164. Fore wing 1027:378; longest marginal seta 79. Hind wing 812:47; longest marginal seta 100.

MALE. Similar to female except for normal sexually dimorphic features and the following. Gaster entirely brown. Antenna ( Fig. 85 View FIGURES 85 – 87 ) with scape minus radicle 1.85× as long as wide, with inner surface more notably sculptured. Fore wing ( Fig. 86 View FIGURES 85 – 87 ) 2.9× as long as wide. Genitalia as in Fig. 87 View FIGURES 85 – 87 .

Diagnosis. Gonatocerus beshbarmak is somewhat similar to the European species G. vidanoi (Viggiani & Jesu) but its female differs from that of the latter in having only 8 (rather than 10 as in G. vidanoi ) mps on the clava, and also by the fore wing at most 2.7× as long as wide (fore wing is about 3.3× as long as wide in G. vidanoi ). Also see the diagnosis of G. berezovskiyi .

Etymology. The species name (a noun in apposition) is that of a popular dish in Kyrgyzstan.

Hosts. Unknown.
