Redescription. FEMALE (holotype and non-type specimens). Body length 700–1045 µm. Body ( Fig. 243 View FIGURES 242 – 244 ) mostly brown to dark brown, antenna brown except pedicel a little lighter; legs light brown to brown.

Antenna ( Figs 244 View FIGURES 242 – 244 , 245 View FIGURES 245 – 247 ) with radicle a little more than 0.25x total length of scape, remainder of scape 2.8–2.9x as long as wide, slightly longitudinally striate; pedicel longer than F1; F2 longer than F1 and more or less subequal in length to the following funicle segments, F1–F3 without mps; F4 usually without but sometimes with 1 mps (often on just one of the antennae), F5 usually with 2 but sometimes with 1 or, rarely, without mps; F6–F8 usually each with 2 mps (F6 sometimes with just 1 or, occasionally, without mps, and F7 rarely with just 1 mps); clava 2.8–3.2x as long as wide, with 8 mps, a little shorter than combined length of F6–F8.

Mesosoma ( Fig. 243 View FIGURES 242 – 244 ). Mesoscutum and scutellum with weak sculpture (best seen in dry specimens). Propodeum with 2 fine submedian carinae, slightly curving towards each other and almost extending to but not touching anterior margin of propodeum. Forewing ( Figs 242 View FIGURES 242 – 244 , 246 View FIGURES 245 – 247 ) 3.1–3.4x as long as wide; longest marginal seta 0.2–0.3x maximum wing width; disc with a slight brownish tinge throughout, almost hyaline, bare behind submarginal vein and densely setose elsewhere, including behind marginal and stigmal veins anterior to cubital row of setae. Hind wing ( Fig. 242 View FIGURES 242 – 244 ) 16–18x as long as wide; longest marginal seta 1.9–2.4x maximum wing width; disc with a row of setae along each margin and numerous scattered setae (denser at apex), with a slight brownish tinge throughout, more so apically.

Petiole subtrapezoidal, about 1.8x as wide as long. Gaster ( Fig. 247 View FIGURES 245 – 247 ) longer than mesosoma; ovipositor rather short, 0.7–0.75x length of gaster, not or barely exserted beyond apex of gaster by at most 0.1x own length; 1.1–1.4x as long as mesotibia.

Measurements (µm) of the holotype. Total body length: 1008; head: 184; mesosoma 369; petiole 30; gaster 498; ovipositor 442. Antenna: radicle 37; rest of scape 100; pedicel 61; F1 36; F2 50; F3 55; F4 47; F5 57; F6 55; F7 56; F8 57; clava 145. Forewing 1095:339; longest marginal seta 97. Hind wing 800:45; longest marginal seta 106.

Description. MALE (previously unknown, specimens from Argentina and Chile). Body length 630–900 µm. Similar to female except for normal sexually dimorphic features and the following. Antenna ( Fig. 248 View FIGURES 248 – 252 ) brown. Body as in Fig. 249 View FIGURES 248 – 252 ; dorsellum, propodeum, and petiole as in Fig. 250 View FIGURES 248 – 252 . Wings as in Fig. 251 View FIGURES 248 – 252 , forewing 3.1–3.2x as long as wide. Genitalia as in Fig. 252 View FIGURES 248 – 252 , apodeme of genital sternite inconspicuous.

Diagnosis. Gonatocerus (Cosmocomoidea) carahuensis   is a member of the chusqueicolus   subgroup of the ater species group. Females are characterized by a relatively short ovipositor ( Figs 243 View FIGURES 242 – 244 , 247 View FIGURES 245 – 247 ), about 1.1– 1.4x as long as mesotibia, which is not or barely exserted beyond the apex of the gaster. It is very similar to larger G. (Cosmocomoidea) schajovskoii (Ogloblin)   , from which it differs by its finer propodeal submedian carinae, relatively shorter F2–F4 and a relatively longer F8 of the female antenna ( Figs 244 View FIGURES 242 – 244 , 245 View FIGURES 245 – 247 ), a little narrower forewing ( Figs 242 View FIGURES 242 – 244 , 246 View FIGURES 245 – 247 ), and also by a somewhat darker color of the gaster, which is usually almost concolorous with the mesosoma ( Fig. 243 View FIGURES 242 – 244 ). Occasionally it may be difficult to distinguish large specimens of G. carahuensis   from small specimens of G. schajovskoii   .

Distribution. NEOTROPICAL: Argentina, and Chile *.

Host. Tapajosa rubromarginata (Signoret)   ( Cicadellidae   ) [a factitious host, new record]. The three female specimens that emerged from this host in Pucará, Neuquén, Argentina, are significantly larger (body length 1170–1300 µm) than the specimens collected from wild habitats. One of these specimens lacks mps from F5 of one antenna. We presume that T. rubromarginata   (and its eggs) must be larger than the still unknown natural host(s) of G. carahuensis   . No members of Proconiini   were collected in its type locality so we cannot identify a possible natural host; most likely, that could be a member of Cicadellini   .
