Diagnosis. Cell r 1 closed to the confluence of the veins R 1 and R 2+3. Both surstyli with one lobe apically, inward directed, inner margins curved and outer margins nearly straight; both surstyli without sinus at junction with epandrium; left surstylus with lower margin rounded; right surstylus with upper margin nearly straight; both surstyli with apex upwards directed, without sinus in union with epandrium in lateral view. Gonopods thickened, with apices acute; right gonopod slightly more acute than left one. Tip of distiphallus straight and acute, without phallic processes. Phallus trifid, all ejaculatory ducts situated little before apex; lateral ejaculatory ducts with inner margins forming straight line in dorsal view.
Intraspecific variability. RAFAEL (1988) provided a complete description and illustration of the Brazilian holotype; however, we found intraspecific variation, therefore, we provide a comparison of the Colombian and Brazilian specimens (between parenthesis, when comparable).
Male. Head ( Figs 33–34 View Figs 33–43 ). Occiput dark brown, brown pruinose. Antenna brown ( Fig. 35 View Figs 33–43 ) (versus antenna black in the holotype). Thorax ( Figs 34–36 View Figs 33–43 ). Postpronotal lobe light brown, light brown pruinose. Notopleuron concolorous with scutum. Mesopleuron brown, brown pruinose. Mediotergite brown pruinose. Wing ( Fig. 37 View Figs 33–43 ). Length 2.2 mm (versus 1.8 mm), width 0.7 mm (versus 0.6 mm), membrane slightly infuscate, pterostigma occupying 2/3 of third costal section (versus pterostigma occupying a little more than half of third costal section). Halter brown (versus halter dark brown). Abdomen ( Figs 34–38 View Figs 33–43 ). Tergite 1 light brown basally, dark brown posterolaterally; syntergosternite 8 dark brown, gray-brown pruinose, with long apical setae. Terminalia ( Figs 39–43 View Figs 33–43 ). Epandrium and surstyli brown ( Fig. 39 View Figs 33–43 ). Surstyli ( Figs 39–41 View Figs 33–43 ) subsymmetrical, completely setose, with long setae apically; both surstyli with one lobe apically, directed inward, inner margin curved and outer margin nearly straight and lower margin slightly truncated ( Fig. 39 View Figs 33–43 ); left surstylus with lower margin rounded, right surstylus with upper margin nearly straight, both surstyli with apex upwards directed, without sinus in union with epandrium in lateral view ( Figs 40–41 View Figs 33–43 ). Gonopods subsymmetrical, thickened, with apices acute, right slightly more acute than left one ( Figs 40–41 View Figs 33–43 ). Tip of distiphallus straight and acute, without phallic processes ( Fig. 42A View Figs 33–43 ). Ejaculatory apodeme parasol-shaped ( Fig. 43 View Figs 33–43 ). Phallus trifid, all ejaculatory ducts situated little before apex in dorsal and lateral view ( Figs 42A–B View Figs 33–43 ).
Habitat. The specimen was collected in preserved areas of tropical rainforest in the Colombian Amazon, Department of Caquetá.
Geographical distribution. Brazil (Amazonas) ( RAFAEL 1990), Colombia (Caquetá) (new record) ( Fig. 55 View Fig ).
