Diagnosis. Postpedicel yellow; fore coxa yellow or all coxae brown; wing brown infuscated, anal lobe narrower basally; tergite 1 velvety brown pruinose, tergites 2–5 shiny brown with inconspicuous setae; surstyli subsymmetrical, both thickened medially, with inner margins straight; apex of phallic guide stout and long, with two thin setae ventrally; ejaculatory apodeme funnel-shaped, leaning to one side; phallus trifid, with ejaculatory ducts short and backwards directed.

Intraspecific variability. Rafael (1990) provided a complete description and illustrations of the Brazilian holotype; however, we found variations in the Colombian specimens. Because of this, we provide a comparison of the variations between the Colombian and Brazilian specimens (between parenthesis, when comparable). MALE. Length 3.1 mm (versus 4.6 mm in the holotype); postcranium gray pruinose laterally and brown pruinose dorsally ( Fig. 17–18 ); scape brown ( Fig. 19 ); frontal triangle with inconspicuous brown callus (versus frontal triangle with narrowed black callus); scutellum with few tiny setae ( Fig. 20 ); membrane brown infuscate ( Fig. 21 ); all coxae brown ( Fig. 17 ) (versus fore coxae yellow to light brown); femora light yellow in proximal third, yellow in distal three thirds ( Fig. 17 ) (versus femora entirely yellow); hind tibia with posterior erect setae medially (versus hind tibia without posterior erect setae medially); abdomen brown, tergite 1 velvety brown pruinose, with six brown and long setae laterally, tergites 2–5 shiny brown with inconspicuous setae ( Figs 18, 22 ) (versus tergite 1 brown pruinose basally, gray pruinose distally interrupted medially, tergites 2–3 with shiny black spot posterolaterally, tergites 4–5 brown pruinose on 1/4–1/5 basally, other apical areas black), tergites and sternites 6 and 7 as in Fig. 23 ; surstyli subsymmetrical, slightly equal to epandrium length, completely setose, both surstyli thickened medially, thin at bases and apices, with inner margins straight ( Fig. 24 ); both surstyli with tips forward-directed when seen in lateral view ( Figs 25–26 ); gonopods subsymmetrical, left gonopod slightly thinner than right ( Fig. 27 ); apex of phallic guide stout and long, with two thin setae ventrally ( Fig. 28 ); ejaculatory apodeme funnel-shaped, leaning to one side ( Fig. 29 ); phallus trifid, with ejaculatory ducts short and backwards directed ( Fig. 28 ). FEMALE ( Figs 30–32 ). Tergites 2–5 predominantly gray pruinose laterally (versus tergite 4–5 brown pruinose basally, shiny black posterolaterally); ovipositor base light brown, brownish-pruinose ( Fig. 31 ); piercer yellow, except the base brown, apex shiny, straight ( Fig. 32 ).
