Gonatocerus (Cosmocomoidea) gerasim Triapitsyn , sp. n.

( Figs 311–314 View FIGURES 311 – 314 )

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 View FIGURES 311 – 314 ) 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 View FIGURES 311 – 314 ). Mesoscutum and scutellum with inconspicuous sculpture. Propodeum ( Fig. 313 View FIGURES 311 – 314 ) 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 View FIGURES 311 – 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 View FIGURES 311 – 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 View FIGURES 311 – 314 ). 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.
