Description
Description. FEMALE (holotype and paratypes). Body length 1025–1340 µm. Head mostly light brown except interocellar area on vertex brown and trabeculae dark brown; scape light brown, pedicel brown, and flagellum dark brown; mesonotum and petiole mostly orange-brown; legs mostly light brown except metatibia brownish; gaster with 2 dark brown bands on terga in the middle, otherwise light brown to brown. Antenna (Fig. 363) with radicle 0.28–0.29x total length of scape, rest of scape 3.0–3.1x as long as wide, faintly longitudinally striate; pedicel a little longer than F1; F1 notably shorter than F2 and without mps, F2– F5 subequal in length (F2 slightly longer), F7 almost as long as F6 and shorter than F5, F8 a little shorter than F7; mps on F2 (1), F3 (1), F4 (2), F5 (2), F6 (2), F7 (2), and F8 (2); clava with 8 mps, 3.7x as long as wide, a little longer than combined length of F6–F8.
Mesosoma (Fig. 365). Mesoscutum with inconspicuous sculpture, scutellum almost smooth. Propodeum (Fig. 364) with well-developed, complete submedian carinae and with a few inconspicuous wrinkles between submedian and lateral carinae; submedian carinae extending to anterior margin of propodeum and joining each other at dorsellum, the area between them smooth. Forewing (Fig. 366) 4.1–4.2x as long as wide; longest marginal seta about 0.3x maximum wing width; disc with a brownish tinge throughout and a conspicuous brown band behind and just beyond stigmal vein, bare behind venation except for several setae behind stigmal vein. Hind wing 20–21x as long as wide; disc mostly bare except for rows of setae along margins and a few scattered setae basally and apically, with a slight, more or less uniform brownish tinge; longest marginal seta 2.3–2.4x maximum wing width. Petiole about 0.9x as wide as long. Gaster a little longer than mesosoma. Ovipositor about 0.85x length of gaster, barely exserted beyond its apex; ovipositor length: mesotibia length ratio about 1.2:1. Measurements (µm) of the holotype. Body length (of the dry-mounted holotype before it was slidemounted, the head was shriveled) 1025; mesosoma 474; petiole 52; gaster 505; ovipositor 460. Antenna: radicle 63; rest of scape 158; pedicel 66; F1 49; F2 75; F3 73; F4 70; F5 70; F6 61; F7 58; F8 50; clava 215. Forewing 1224:297; longest marginal seta 88. Hind wing 923:45; longest marginal seta 106. MALE. Unknown.
Diagnosis
Diagnosis.Gonatocerus (Cosmocomoidea) logarzoi sp. n. is a member of the ater subgroup of the ater species group. It is very similar to G. (Cosmocomoidea) garchamp sp. n., which has a relatively wider forewing (Fig. 306) and a different propodeal submedian carinal pattern. In G. garchamp the submedian carinae are widening notably from about middle of propodeum towards its anterior margin and extend almost to it, but do not join each other at dorsellum (Fig. 305).
Etymology
Etymology. This species is named in honor of my colleague, friend, and co-author, Guillermo A. Logarzo, who has tirelessly collected fairyflies in Argentina over the past eight years, finding many interesting specimens including several new species, and establishing numerous new host records of the leafhopper egg parasitoids.
Biology and Ecology
Host.Tretogonia notatifrons Melichar (Cicadellidae).
