Isoscella ventana (Dognin, 1897) (Fig. 1E) Isoscella ventana is the northernmost representative of the genus, it is found in Colombia and Venezuela, and can be recognized by the slightly rounded forewing apices and brighter orange coloration in general as well as genitalia characters. Distribution in Colombia includes Boyacá, Casanare, Cundinamarca, and Valle del Cauca departments. Our report from Casanare is the first from this department.
