Gonatocerus (Cosmocomoidea) seminiger

Gonatocerus (Cosmocomoidea) seminiger (Ogloblin, 1959) (Figs 464–467) Lymaenon (Cosmocomoidea) seminiger Ogloblin 1959b: 53 –56. Type locality: San Mateo, Esmeraldas, Ecuador. Gonatocerus (Cosmocomoidea) seminiger (Ogloblin): De Santis 1979: 368 (catalog). Gonatocerus seminiger (Ogloblin): Yoshimoto 1990: 41 (listed in ater species group). Lymaenon seminiger Ogloblin: Loiácono et al. 2005: 17 (type information; types incorrectly listed as presumably miss- ing). Type material examined. Parts of holotype or/and paratype female(s) [MLPA] on slide labeled [ip]: “ Lymaenon [an illegible word] seminiger A. Ogl. ♀♀ Cosmoc San Mateo, Esmeral-das, Rep. Ecuador. J. Förster 29–XI–1956 [? Ant. fig. – iR, followed by an illegible word]”. The species was described from two females. The mounting medium on the original slide (Fig. 4) was so dark that parts of the two poorly preserved, fragmented specimens were hardly visible, and in the course of this study they were remounted into Canada balsam under five coverslips, as follows: 1) head; 2) two forewings, both incomplete; 3) two fragmented antennae, with F8 of both and a clava of one missing; 4) body and fragmented leg segments; 5) one almost complete forewing, one fragmented forewing, and fragments of apparently two hind wings. It appears that most of these parts belong to just one specimen, and the only remaining part of the second specimen may be the fragments of two forewings, although it is also possible that these fragments belong to both specimens of the type series. It is impossible to determine whether most of the parts belong to the holotype or the paratype; we just assume that the more complete specimen might had been chosen by Ogloblin as the holotype. Redescription. FEMALE (?holotype or?paratype). Body mostly orange-yellow except dorsellum, mesopleura, and propodeum dark brown; gaster with brown bands on terga; scape yellow-brown, remainder of antenna brown to dark brown; legs yellow-brown except metatibia brown. Antenna (Fig. 464) with radicle about 0.25x total length of scape, rest of scape 3.2x as long as wide, longitudinally striate; F1 longer than pedicel and without mps, shorter than F2–F4 and subequal to F5 and F6, and longer than F7; F2–F4 more or less subequal in length, F2–F7 each with 2 mps; clava with 8 mps, about 3.7x as long as wide. Mesoscutum and scutellum smooth; propodeum (Fig. 465) with well-developed, subparallel submedian carinae extending to and almost connecting to each other just below propodeal anterior margin, and with one transverse rugosity closer to anterior margin of propodeum almost connecting each submedian and lateral carina [not many rugosities in the posterior half of propodeum as erroneously described and illustrated by Ogloblin (1959b, fig. 17)]. Forewing (Fig. 466) 3.5x as long as wide; longest marginal seta about 0.2x maximum wing width; disc strongly infuscate, slightly more so behind stigmal vein, bare behind submarginal vein, cubital row of setae complete, with setae sparse between it and marginal and stigmal veins, remainder of disc densely setose. Petiole about 1.2x as long as wide; ovipositor (Fig. 467) about 0.65x length of gaster, exserted beyond gastral apex by about 0.14–0.17x own length; about 1.1x as long as mesotibia. Measurements (µm) of the? holotype or the? paratype. Petiole 92; gaster 890; ovipositor 700. Antenna: radicle 82; rest of scape 236; pedicel 79; F1 103; F2 133; F3 131; F4 127; F5 103; F6 103; F7 88; clava 333. Forewing 1906:547; longest marginal seta 106. MALE. Unknown. Diagnosis. Gonatocerus (Cosmocomoidea) seminiger is a member of the morrilli subgroup of the ater species group. It is a large species (body length of holotype 1.89 mm according to original description), and the female is characterized by the following unique combination: mesosoma with mesoscutum and scutellum orange-yellow, contrasting with dark brown dorsellum and propodeum; forewing (Fig. 466) with disc strongly infuscate, slightly more so behind stigmal vein, and the cubital row of setae complete, with setae sparse between it and the marginal and stigmal veins. Distribution. NEOTROPICAL: Ecuador. Hosts. Unknown. Comments. Numerous specimens in BMNH from Nova Teutonia, Santa Catarina, Brazil (collected by F. Plaumann), misidentified by B.R. Subba Rao as Lymaenon seminiger, in fact belong to a different, apparently undescribed, species of G. (Cosmocomoidea).
