Material examined (1 J). COLOMBIA, Caquetá, San José del Fragua, / Vda. [Vereda] Bellavista, Fca.[Finca] Mi Ranchito, / 01º18’23’’N / 76º00’33’’W, 265 m [eters], / 29.Mar[ III] –12.Abr[ IV].2017, / trampa Malaise en dosel del bosque, / Y. Ramos-Pastrana ( LEUA – 00000049809) (photographed specimen).

Diagnosis. Pedicel with four setae dorsally and two ventrally. Hind tibia with 1–2 strong setae medially. Both surstyli with outer margins slightly curved; inner margin of each surstylus forming an angle of approximately 130º centrally, apices truncated and converging, without sinus at junction with epandrium in lateral view. Gonopods with apices rounded; left gonopod with apex slightly thinner than right one. Tip of distiphallus short and acute, without phallic processes. Phallus trifid, one ejaculatory duct apically, the other two medially and forward-directed in ventral view, not visible in dorsal view.

Intraspecific variability. RAFAEL (1990) provided a complete description and illustrations of the Brazilian holotype; however, we found variations in the Colombian material. Therefore, we provide a comparison of the variations between the Colombian and Brazilian specimens (between parenthesis, when comparable).

Antenna ( Fig. 46 View Figs 44–54 ) brown ( versus antenna dark brown to black in the holotype); pedicel with four setae dorsally and two ventrally. Thorax ( Figs 45, 47 View Figs 44–54 ).

Legs ( Fig. 44 View Figs 44–54 ) entirely brown, except tarsomeres 1–4 light brown ( versus legs black, except femoro-tibial articulations and all tarsomeres light brown); pulvilli light brown. Abdomen ( Figs 45, 49 View Figs 44–54 ) brown, gray-brown pruinose, with long setae laterally and short scattered setae dorsally; tergite 1 light brown basally, dark brown posterolaterally; tergite 1–5 with transverse bands brown pruinose dorsally; tergite 6 clearly shorter than tergite 5; syntergosternite 8 with long apical setae (Fig. X).

Surstyli ( Figs 50–52 View Figs 44–54 ) subsymmetrical and setose, with long seta apically; both surstyli with outer margins slightly curved, inner margin of each surstylus forming angle of approximately 130º centrally, apices truncated and converging ( Fig. 50 View Figs 44–54 ); both surstyli with apices rounded; left surstylus in lateral view with apex slightly thinner than right one ( Figs 51–52 View Figs 44–54 ). Gonopods subsymmetrical; left gonopod with apex slightly thinner than right one ( Figs 51–52 View Figs 44–54 ). Tip of distiphallus short with tip acute ( Fig. 53A View Figs 44–54 ). Ejaculatory apodeme pin-shaped ( Fig. 54 View Figs 44–54 ). Phallus trifid, one ejaculatory duct apically, the other two medially and forward-directed in ventral view, not visible in dorsal view ( Figs 53A–B View Figs 44–54 ).

Habitat. The specimen was collected in the canopy in preserved areas of tropical rainforest in the Colombian Amazon, Department of Caquetá.
