Male holotype from Colon Province, Santa Rosa, Panama [ 09°02’00.38”N , 80°10’03.10’W], XI.1945 , C. D. Michener ( AMNH ). Etymology. The specific name is an adjective referring to the marked and conspicuous lateral carina on the male chelicerae. Diagnosis. The male of E. carinata sp. nov. resembles those of E. igarape Silva, Lise & Carico, 2008 by the presence of the ventral division of the median apophysis (VD) ( Silva et al . 2008 , p. 96, figs 100, 101), but can be distinguished by the shorter and wider ectal division (ECD) of the retrolateral tibial apophysis (RTA) ( Fig. 2 ).
