Pseudataenius socialis – Brown 1927: 290 ; Woodruff 1973: 135 ; Cartwright 1974: 14-16 ; Ratcliffe and Paulsen 2008: 239-240. Diagnosis . Male head finely punctate; protibia with 2 lateral teeth, terminal spur long, parallel, hooked apically; pronotum without smooth midline. Female clypeus strongly transversely wrinkled; protibia with 3 lateral teeth, terminal spur straight. Description . Length 4.2-5.0 mm. Male head short and broad ( Fig. 29 ), finely reflexed clypeal margin widely rounded on each side of shallow median emargination, sides nearly straight to sharply rounded, fimbriate genae; surface of head uniformly, very finely punctate ( Fig. 32 ). Pronotum weakly convex, sides widely arcuate to slightly sinuate base; sides fimbriate with long setae; surface with mixed very fine and very moderate punctures throughout. Elytra convex, long, subparallel sided humeri not dentate; striae fine, strial punctures shallow; intervals slightly convex with scattered very minute punctures, interval 10 flat. Ventral surface finely punctate; abdominal sternites finely fluted along sutures, surface minutely alutaceous with scattered punctures more noticeable at sides; apical lip of pygidium convex, shiny, eroded area finely roughened. Legs long; meso- and metafemora without posterior lines; protibia narrow with only 2 large teeth, terminal spur long, parallel with tip bent inward ( Fig. 30 ); metatibial apex with long setae and accessory spine; tarsi very long and slender, basal tarsomere of metatarsus longer than upper tibial spur and equal in length to following 3 tarsomeres combined, tarsomere 5 as long as 2 preceding tarsomeres together. Epipharynx as in Fig. 37 . Male genitalia as in Fig. 35 . Female color usually darker than in male; head smaller, clypeus more deeply emarginate at middle ( Fig. 31 ), surface transversely wrinkled, posterior clypeus and vertex finely, closely punctate; pronotum more convex, surface with mixed very fine and moderately coarse punctures throughout, coarse punctures irregularly spaced ( Fig. 33 ). Abdominal sternites, pygidium shorter with narrower apical lip. Legs shorter than in male; meso- and metafemur with fine posterior lines; protibia with 3 normal lateral teeth and slender terminal spur; tarsi shorter than in male. Type material .
