Material examined. COLOMBIA: Chocó • 7 work- ers; Lloró; 05°30′00″N, 076°31′00″W; alt. 90 m; 25 Oct. 2000; J. Neita leg.; UNAB 545, MEFLG 6936 .

Identification. Cephalic and mesonotal protuberances horn-like; preocular carina curves above eye; frontal lobes broadly expanded, semicircular; pronotum without median paired denticles, humeral prominence weakly developed and postero-lateral tubercle more developed, antero-ventral corner rectangular; and mesonotum with anterior pair of very prominent spines and posterior pair of very low denticles (Kempf 1968).

Distribution. Cyphomyrmex cornutus is widely distributed in Central and South America. It has been recorded from Veracruz state in Mexico, south to Costa Rica, Co- lombia, Ecuador, French Guiana, and the Brazilian states of Acre and Bahia. This ample and somewhat disjunct distribution suggests that C. cornutus might have a con- tinuous distribution throughout Central America and northern South America (Adams and Longino 2007; Mi- randa et al. 2012; Vergara-Navarro and Serna 2013; San- tos et al. 2017).
