Diagnosis.
Disersus inca can be distinguished from all other Disersus by the combination of the entirely pubescent metatibia, except for a narrow glabrous patch apically (Fig. 22) and the rounded elytral apices of the male.
Intraspecific variation.
Members of this species vary slightly in size and color, from a reddish-brown to medium brown, and in total length from 6.6-7.6 mm. The female differs from the male in having slightly produced elytral apices and a rounded apical abdominal ventrite (see Spangler and Santiago-Fragoso 1987).
Habitat and distribution.
Previously, Disersus inca was only collected in blacklight traps near montane streams in Ecuador, Colombia, and Peru ( Spangler and Santiago-Fragoso 1987), this species is known to occur in the Cordillera Oriental in southwestern Venezuela from streams above 1000m in elevation (Fig. 1).
Associated species.
No other laraine species were collected with Disersus inca .
