Gonatocerus sp.: Triapitsyn 2007: 59, 61 (illustrations).
Type material. Holotype female [UCRC ENT 162816] on slide: MEXICO. TAMAULIPAS, Gómez Farías, Estación Los Cedros, 23°03’00’’N 99°09’03’’W, 340 m, 12.v.2002, S.V. Triapitsyn, V.V. Berezovskiy, A. Córdoba-Torres, Malaise trap.
Description. FEMALE (holotype). Body brown to dark brown, gaster partially a little lighter than mesosoma; scape and pedicel light brown, flagellum dark brown except F5 and F6 yellowish-white; coxae brown, femora light brown to brown (mostly medially), tibiae and tarsi mostly light brown.
Antenna (Fig. 311) with radicle 0.31x total length of scape, rest of scape 3.9–4.0x as long as wide, longitudinally striate; pedicel almost as long as F1; F2 slightly longer than F3 but the two the longest funicle segments, F4–F8 each a little shorter than the preceding segment except F6 as long as F7; F1 without mps, F2 with 1 mps, F3–F8 each with 2 mps; clava with 8 mps, about3.6 x as long as wide, longer than combined length of F6–F8.
Mesosoma (Fig. 312). Mesoscutum and scutellum with inconspicuous sculpture. Propodeum (Fig. 313) with median oval area bounded by submedian carinae narrow and almost smooth except for a few wrinkles posteriorly, and with several transverse rugae lateral to submedian carinae in posterior half of propodeum and numerous wrinkles elsewhere. Forewing (Fig. 314) 4.0x as long as wide; longest marginal seta 0.25x maximum wing width; disc with a conspicuous brownish tinge throughout (a little more pronounced, as an inconspicuous brownish spot, at posterior margin of wing just beyond apex of venation), bare behind venation except for a few setae just behind apex of marginal vein and also behind stigmal vein. Hind wing (Fig. 314) about 20x as long as wide; disc bare behind venation, with a row of setae along each margin and a few additional setae basally and apically, and with a slight, uniform brownish tinge; longest marginal seta 2.1x maximum wing width.
Metasoma (Fig. 312). Petiole about 1.5x as long as wide. Gaster a little longer than mesosoma. Ovipositor about 0.7x length of gaster, barely exserted beyond its apex; ovipositor length: mesotibia length ratio 0.9:1.
Measurements (µm) of the holotype. Body (taken from dry specimen) 1816; head (taken from dry specimen) 300; mesosoma 738; petiole 147; gaster 775; ovipositor 566. Antenna: radicle 122; rest of scape 276; pedicel 85; F1 88; F2 145; F3 142; F4 127; F5 109; F6 100; F7 100; F8 82; clava 340. Forewing 1876:467; longest marginal seta 118. Hind wing 1390:70; longest marginal seta 148.
MALE. Unknown.
Diagnosis. Gonatocerus (Cosmocomoidea) gerasim sp. n. is a member of the morrilli subgroup of the ater species group. It is similar to G. (Cosmocomoidea) morrilli (Howard) and other species of the morrilli complex, such as G. annulicornis (Ogloblin), G. barbos sp. n., G. kiskis sp. n., G. rakitovi sp. n., G. quirogai (Ogloblin), and G. walkerjonesi Triapitsyn, from which it differs by its brown to dark brown body.
Etymology. Gerasim (a noun in apposition) is a male name (in Russian).
Hosts. Unknown.
