Type locality: San Mateo, Esmeraldas, Ecuador. Gonatocerus ( Cosmocomoidea ) coxalis (Ogloblin) : De Santis 1979 : 367 (catalog). Gonatocerus coxalis (Ogloblin) : Yoshimoto 1990 : 40 (listed in ater species group). Lymaenon coxalis Ogloblin : Loiácono et al. 2005 : 17 (type information; types incorrectly listed as presumably missing). Type material examined. Parts of holotype or/and paratype female(s) [ MLPA ] on slide labeled [ip]: “( Cosmocomoidea ) Lymaenon coxalis A. Ogl. ♀♀ San Mateo, Esmeraldas Ecuador , J. Förster 14–VI–1956 .”. According to the original description 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, so in the course of this study they were remounted into Canada balsam under five coverslips, as follows: 1) head; 2) two forewings, one incomplete and the other split in two parts; 3) two fragmented antennae (F8 of one of them missing); 4) body and fragmented leg segments; 5) a fragment of a forewing. It appears that most of the parts belong to just one specimen, and the only remaining part of the second specimen may be the fragment of a forewing, although it is also possible that these fragments belonged to both specimens of the type series. It is also impossible to determine whether most of these parts belong to the holotype or the paratype ; we assume that the more complete specimen would have been chosen by Ogloblin as the holotype . Redescription. FEMALE (holotype/paratype). Head, flagellum, and mesosoma dark brown, metasoma brown; scape, pedicel, and legs light brown except metatibia slightly darker. FIGURES 273–276. Gonatocerus ( Cosmocomoidea ) coxalis ♀ (?holotype and/or?paratype): 273, antenna (F8 is missing); 274, dorsellum and propodeum; 275, mesosoma and metasoma; 276, forewing. Antenna ( Fig. 273 ) with radicle about 0.25x total length of scape, rest of scape 3.7x as long as wide, longitudinally striate; F1 almost as long as pedicel, as long as F8, and much shorter than F2; F2 and F3 subequal and the longest funicle segments, slightly longer than F4 and F5; F6 and F7 subequal, slightly shorter than F4 or F5; F1 without mps, F2 and F3 each with 1 mps, F4–F8 each with 2 mps; clava with 8 mps, about 3.7x as long as wide. Mesosoma ( Fig. 275 ). Mesoscutum and scutellum almost smooth; propodeum ( Fig. 274 ) with well-developed, subparallel submedian carinae extending to and connecting just below anterior margin of propodeum, and with a transverse rugosity closer to posterior than anterior margin connecting each submedian and lateral carina [not many rugosities in posterior half of propodeum as originally described and erroneously illustrated by Ogloblin (1959b, fig. 13) ]. Forewing ( Fig. 276 ) about 3.9x as long as wide; longest marginal seta about 0.25x maximum wing width; disc with a large oval brown spot in apical half (measured from apex of venation) not extending to anterior or posterior margins, bare behind submarginal and marginal veins and setose elsewhere. Petiole about 1.2x as long as wide; gaster just a little longer than mesosoma; ovipositor about 0.9x length of gaster, barely exserted beyond gastral apex; about 1.1x as long as mesotibia. Measurements (µm) of the holotype / paratype . Mesosoma 566; petiole 85; gaster 576; ovipositor 512. Antenna: radicle 33; rest of scape 94; pedicel 36; F1 33; F2 49; F3 49; F4 46; F5 46; F6 42; F7 42; F8 33; clava 142. Forewing 1427:369; longest marginal seta 94. MALE. Unknown. Diagnosis. Gonatocerus ( Cosmocomoidea ) coxalis is a member of the morrilli subgroup of the ater species group. It is characterized by the following unique combination: propodeum with well-developed, subparallel submedian carinae extending to and connecting just below anterior margin, and with transverse rugosity closer to posterior margin connecting each submedian and lateral carina ( Fig. 274 ); and forewing disc with a large oval brown spot in the apical half (measured from apex of venation) not extending to anterior or posterior margins, and bare behind submarginal and marginal veins ( Fig. 276 ). It may be confused with the undescribed G. ( Cosmocomoidea ) sp. 3 from the G. ( Cosmocomoidea ) tuberculifemur (Ogloblin) species complex, known from Argentina , Bolivia , and Brazil (Triapitsyn et al. 2008). Both have an oval brown spot on the forewing disc, but the latter has the petiole wider than long and no rugosity on the propodeum connecting each submedian and lateral carina. Distribution. NEOTROPICAL: Ecuador . Hosts. Unknown.
