This is an uncommon species from Brazil. We base our description mainly upon examination of type material, specimens collected in São Paulo state, and the morphological characters given in Py-Daniel (1987) and Pepinelli et al. (2003) .

Abdomen— tergites brown with silver pruinosity, except tergite II whitish. Tergal plates developed; sternal plates undeveloped. Sternites greyish black; genitalia black. Eighth sternite weakly sclerotised with irregularly distributed setae on posterior margin; gonapophyses glabrous nearly same length as eighth sternite at mid point, subtriangular, membranous and strongly sclerotised on internal margins ( Fig. 110 View PLATE 8 ). Cercus hemispherical, covered with long brown setae; paraproct subrectangular with ventral extension triangular, truncated apically and about one and a half times as long as cercus, highly sclerotised with weak slight basal prominence on posterior margin at junction with cercus; paraproct covered with long hairs basally and small setae toward apex ( Fig. 126 View PLATE 10 ). Genital fork with stem long and slender; termination of lateral arms with anterior and posterior processes poorly developed ( Fig. 141 View PLATE 11 ). Spermatheca subspherical, without external sculpturing or internal spicules; area of insertion of spermathecal duct membranous.

Male. General body colour black. Body length (specimens pinned) 2.9mm (n=1), wing length 2.5 mm (n=1), wing width 1.2 mm (n=1).

Head — holoptic with dark red eyes. Remainder of head coloration as in female.

Thorax— scutum black covered with recumbent, golden setae. Scutal pattern varies slightly with light incidence: with anterior light source thorax black with faint pruinosity on anterior margin ( Fig. 160 View PLATE 12 ); humeri black; lateral and posterior margins weakly pruinose. With light source posterior to specimen thorax black ( Fig. 161 View PLATE 12 ); humeri, lateral and posterior margins of scutum black. Scutellum black with recumbent, golden setae interspersed with long, black setae on posterior margin. Postnotum black with silvery grey pruinosity. Wing setation as in female, except Subcosta with 4–7 setae on basal half its length. Leg coloration as in female.

Genitalia black; tergal plates developed; sternal plates undeveloped. Gonocoxite subrectangular; gonostyle trapezoidal, nearly same length as gonocoxite, with ridge on median region, and terminating in small spine [only visible at higher magnification]; gonocoxite and gonostyle covered with long hairs ( Fig. 184 View PLATE 14 ). Ventral plate subtriangular, sclerotised, pointed apically and with small basal arms; main body of ventral plate covered with small hairs ( Fig. 198 View PLATE 15 ). Median sclerite Y-shaped with apical incision ( Fig. 210 View PLATE 16 ). Paramere with developed and sclerotised basal process and several stout teeth apically ( Fig. 223 View PLATE 17 ).
