Brachypterodina gonzalezi Flowers , new species

( Fig. 7–8 , 28 , 34 )

Holotype: Female. Length 3.6 mm. Head, pronotum, elytra and underside bronze­black; antenna reddish brown, darker apically. Legs reddish brown, sides of femora dark brown. Head with clypeus coarsely punctate, surface between punctures shining, weakly microreticulate, apex of clypeus truncate. Frons coarsely, rugosely punctate, surface between punctures microreticulate. Mouthparts reddish brown; with apex of labrum emarginate, with 2 dorsal setae and long lateral setae at outer angles. Prothorax distinctly wider than long, L/W = 0.68. Pronotum with anterior angles subquadrate, posterior angles acute; all angles with a seta­bearing puncture; greatest width of pronotum at middle; disc regularly, strongly punctate, with punctures separated by a distance slightly greater than their own diameters; surface between punctures shining, with numerous punctulae. Prosternum microreticulate, declivous and expanded laterally behind coxae, width of intercoxal process 0.87 x diameter of procoxa. Lateral arms of prosternum with anterior margin straight, a weakly reflexed margin anterior to the procoxae. Elytra striate, with punctures in striae separated by distance less than he diameter of a puncture; surface of elytral intervals finely microreticulate; basal half of elytra with elongate, high tubercles on intervals 2–8 ( Fig. 8 ), interval 6 subangulate, intervals 7–8 weakly costate; humeri not prominent, broadly rounded, width across humeri 0.97 x width across pronotum; basal calli obsolete; postbasal depression lacking; sides broadly rounded, convergent; apices weakly produced. Hind wings absent. Abdomen with surface of segments alutaceous. Female genitalia: Segments VIII–XI forming elongate ovipositor similar to Fig. 25 . Spermatheca ( Fig. 28 ) with pump and receptacle not differentiated, spermathecal duct and gland approximate on the apex of the receptacle; spermathecal duct moderately long, sclerotized, thin in proximal third, abruptly widened, convoluted and more strongly sclerotized in distal two thirds.
