Material examined. COLOMBIA: Caquetá • 3 workers; Florencia; 01°30′4″N, 075°39′42″W; alt. 280 m; Sep. 2017; UNAB members leg.; UNAB 4737 .

Identification. Frontal lobes in frontalview subquadrate, each posterior margin straight and inclined, anterolateral margins convex; posterior cephalic profile rounded; eyes with a maximum of 10 ommatidia along the shortest axis; and postpetiole with posteroventral process relatively big and usually dentiform ( Lattke 1997).

Distribution. Previous Colombian records are from Valle del Cauca, thus this new record from Caquetá ex- pands the distribution of this species from the Andes into the Amazon region ( Fig. 1A ). Besides Colombia, Apterostigma peruvianum is also present in Bolivia, Ec- uador, Peru, and Venezuela ( Kempf 1972; Lattke 1997; Fernández and Sendoya 2004).
