( Figs. 6D , 11 G–I, 20)

Material examined: UARC: 1 ♂ 10 December 2005 , Chocó Department, Acandí Municipality, Vereda Rufino, Quebrada Capitancito 8.5787, -77.3109 30m a.s.l., Leg: C. Botero . ANDES–E: Same data but in 5 ♂♂ .

Remarks: This species was described by Donnelly (1992) from Panama. Here, we report it for the first time from Chocó Department in Colombia. Males are small (abdomen close to 35mm), and have distal abdominal segments (S7–S10) completely orange, cerci strongly curved in dorsal view ( Fig. 11G ) without ventrobasal convexity ( Fig. 11H ) and with a distance between bifurcation of medial process and tip around one fourth the length of the cerci ( Fig 11G ). We did not examine the female.
