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).
