Lectotype male (present designation). Body: 7.0 mm. Wing: 3.9 mm. Head. Flagellum oval small, shorter than scape and pedicel combined. Face darkbrown, shorter than frons, narrowly dichoptic. Post��cranium dark��brown with brown pruinescence; pair of ocellar setae divergent; 3 long upper postocellar bristles bent forward at basal third; occipital series with disordered, more numerous, long and scattered bristles on upper portion of postcranium, very short, almost inconspicuous on inferior half. Thorax dark��brown; pronotum, pleurae and scutum pruinose, except small circular area in dorsocentral line before base of wing, postpronotal lobe and dorsum of scutellum shiny, lacking pruinescence; dorsum of pronotum with gold��brown tomentum; notopleuron, pleurae and margins of scutellum with grayish pruinescense. Pronotum of medium length. Scutum with short bristles; acr row irregularly biserial anteriorly; decreasing in number posteriorly and becomes uniserial on posterior half of scutum; dc uniserial although more numerous anteriorly; intralars scattered. Outstanding bristles: 1 pair of posterior dc bristle; 2���3 thin npl; 1 postalar; 1 pair of scutellar apical bristles parallel, something short and 2 weak and short lateral bristles. Propleuron with short, inconspicuous bristle. Wing (Fig. 29): narrow, hyaline, stigma lacking, anal lobe narrow, alular incision greater than 90 ��; R 4 + 5 and M 1 slightly convergent, almost parallel. Legs clothed in brown bristles; coxae, trochanters, tarsomeres 4���5 and hind femur brown; tarsomeres 1���3, fore and mid femora and tibiae yellow; hind tibia pale��brown, yellow at extremities. Hind femur faintly inflated, approximately 5.8X longer than wide; hind tibia straight, lacking ventral keel. Fore and mid pulvilli whitish, twice length of claws, about 3 X longer than the hind ones; hind pulvilli brown, half of length of claws. Outstanding bristles very long: fore tibia with 1 A and 1 P preapical as long as tarsomere 1, reaching apex of segment; mid tibia with 3 AD distinctly long and robust, especially 2 basal bristles, 1 AV on basal third reaching apex of tibia and 1 apical PV crossing apex of tarsomere 1; mid tarsomere 1 with 1 AD and 1 PV preapical, 1 AD and 1 PV in third, very long, besides other long and thin bristles; hind trochanter with 1 V short spine and 1 PV spine��like bristle; hind femur with 8 AV spine��like bristles, 13 V thorns with protuberant bases, 3 PV more apical spine��like bristles, 2 long thin bristles on distal third and 8 spines with very protuberant bases on basal 2 / 3 of femur. Abdomen: dark��brown with thin, pale��brown bristles; very long and thin, about 5 X length of the thorax; Tg 6���8 short and pruinose; Tg 1 and Tg 2 with long bristles laterally, remaining bristles very short and scattered; sternites pilose with elongate bristles, increasing in length on more distal sternites; distal margin of St 8 with long and wavy bristles. St 6���8 densely pruinose, St 5 ��� 4 sparsely pruinose; segments 2���4 tubular, 5 X as long as wide. Terminalia (Figs. 11���15): pruinose, with long bristles; hypandrium long and slender, right hypandrial lobe wide, almost half of width of hypandrium and as long as hypandrium; dorsal bridge complete; left postgonite widened. Female. Similar to male except as follows. Abdominal pruinescence starting from Tg 7; spine��like bristles of hind femur reduced, 6 AV more slender than in male, 9 AV occupying distal half, PV row with 3 robust preapical bristles and remaining thin and elongate; hind trochanter lacking thorns. Terminalia (Figs. 16���18): ninth segment with large basal protuberance on each side. Tg 9 and St 9 triangular, wide basally and narrowed gradually towards apex; Tg 9 with small medium protuberance near base. Type material. Lectotype ♂: COSTA RICA, [Cartago], La Suisa, April 1922, Pab Schild; Type, Euhybos leptogaster Mel (USNM). Condition: antenna, fore and mid leg and right wing lost, terminalia in tube with glycerin. Paralectotype: same data as lectotype, 1 �� (USNM). Conditions: head, fore legs, left mid leg and right hind leg lost; terminalia in tube with glycerin, right wing mounted on microslide.
