description: Gonatocerus (Cosmocomoidea) concinnus (Ogloblin, 1936)
(Figs 270–272)
Lymaenon concinnus Ogloblin 1936: 46 –48 + plates (láminas) II and III (illustrations). Type locality: Loreto, Misiones, Argentina.
Gonatocerus (Gonatocerus) concinnus (Ogloblin): De Santis 1967: 104 (catalog).
Gonatocerus concinnus (Ogloblin): Yoshimoto 1990: 40 (list); Luft Albarracin et al. 2009: 9 (list; distribution in Argentina).
Lymaenon concinnus Ogloblin: Loiácono et al. 2005: 13 (type information, invalid holotype and paratype designations).
Type material examined. Lectotype female [MLPA], here designated to avoid the existing confusion about the status of the type specimens of this species, on slide labeled: 1. “ Gonatocerus concinnus A. O Loreto, Misiones 25.vii.1932. A. A. O. Typus Fig [iR, ip]”; 2. ‘3868”; 3. [Red circle] “Lecto-type”. This specimen was invalidly designated as a holotype by Loiácono et al. (2005) because the species was described by Ogloblin (1936) from two syntype females. The collection date on the label of the lectotype (25.vii.1932) does not entirely match the first date given in the original description for the species (25.ii.1932). The lectotype, although uncleared, is in fair condition, complete, mounted dorsoventrally, but with the head and gaster somewhat collapsed. Paralectotype: 1 female [MLPA] on slide labeled: “ Gonatocerus concinnus A. O. ♀ Loreto, Misiones 5.XI.1933. Selva.”. The collection date of this specimen matches the second date given for the two female syntypes.
Material examined. ARGENTINA. There is another female in MLPA on slide labeled: 1. “ Gonatocerus concinnus A. O. ♀ Loreto, Misiones 3.ix.1935 Selva. A. A. O. Paratypus [ip]”; 2. ‘3878”; however, this specimen is not part of the type series even though Ogloblin mislabeled it as a “ paratype ”, and thus it is not designated here as a paralectotype. This specimen was invalidly designated as a paratype by Loiácono et al. (2005) .. Redescription. FEMALE (lectotype, paralectotype, and non-type specimen from Loreto). Body length 830–1002 µm. Head and mesosoma mostly yellowish except trabeculae dark brown; scape and pedicel light brown to brown; F1–F4, F8, and clava dark brown, F5–F7 white; legs and mesosoma mostly yellowish except for metatibia and some gastral terga brownish.
Antenna (Fig. 270) with radicle about 0.25x total length of scape, rest of scape 3.0–3.1x as long as wide; pedicel much longer than F1; F1 the shortest funicle segment and lacking mps, F2–F8 more or less subequal in length and each apparently with 2 mps (F6 possibly sometimes with just 1 mps); clava with 8 very long mps, 3.7–4.3x as long as wide, about as long as combined length of F5–F8 or a little less.
Propodeum (Fig. 271) with fine, curved submedian carinae meeting almost at anterior margin but not touching it, otherwise smooth. Forewing (Fig. 272) 2.9–3.1x as long as wide; longest marginal seta about 0.2x maximum wing width; disc with a slight brownish tinge and a brown band behind stigmal vein; bare behind venation except for several setae just behind stigmal vein, and densely setose elsewhere. Hind wing (Fig. 272) 13–15x as long as wide; disc with a row of setae along each margin and a few additional setae, almost hyaline but with a slight brownish tinge apically; longest marginal seta 1.7–1.8x maximum wing width.
Petiole 1.0–1.2x as wide as long; ovipositor short, not exserted beyond apex of gaster; about 0.8x as long as mesotibia.
Measurements (µm) of the lectotype. Total body length (but the head and gaster are shriveled): 830; mesosoma 400; petiole 36. Antenna: radicle 45; rest of scape 166; pedicel 60; F1 19; F2 54; F3 57; F4 63; F5 55; F6 54; F7 54; F8 57; clava 239. Forewing 1107:381; longest marginal seta 82. Hind wing 763:57; longest marginal seta 100.
MALE. Unknown.
Diagnosis. Gonatocerus (Cosmocomoidea) concinnus is a member of the ater subgroup of the ater species group. Females can be recognized among the described species of the subgenus by their white F5–F7 (Fig. 270).
Distribution. NEOTROPICAL: Argentina.
Hosts. Unknown.
