Material examined. COLOMBIA: Antioquia • 1 work- er; Amalfi; 06°51′26″N, 075°07′32″W; alt. 1000 m; 30 Jul. 1997; F. Sernaleg.; MEFLG 40854.

Identification. Eyes prominent (more than nine omma- tidia along the shortest axis); frontal lobes in full-face view subquadrate; anterior margin of clypeus in fullface view concave, lacking shiny cuticular strip; neck lacking median carina; mandibles elongate; anterior margin of pronotum in dorsal view convex, with median emargination and no lateral thickening; and mesopleu- ral ventral carina in lateral view well-developed, thick (Lattke 1997).

Distribution. In Colombia, A. bolivianum was only known from Amazonas, thus the new record from Antioquia (Fig. 1C) suggests this species might be broadly dis- tributed throughout the country (Fig. 1C) (Weber 1938; Kempf 1972; Fernández et al. 1996; Lattke 1997). Apterostigma bolivianum is also known from the following countries in northwestern South America: Bolivia, Ec- uador, Peru, and Venezuela.
