Figs 5, 6, 9–11

Type. Male holotype from San Pablo, San Pedro, Colombia [10°03’07.73”N, 75°16’07.27’W], 13.V.1975, J. A. Kochalka (MCTP 8869).

Etymology. The specific name is a patronym in honor of the late arachnologist James E. Carico, who made many contributions to the taxonomy of the Trechaleidae .

Diagnosis. The male of E. caricoi sp. nov. resembles those of E. redundans (Platnick, 1993) by the long and acute guide (G) of the median apophysis (Silva et al. 2008, p. 107, fig. 153), but can be distinguished by the slender and curved tip of the guide (G) (Fig. 5), by the presence of a lateral tooth-like projection on the dorsal division (DD) of the median apophysis (Figs 9, 10) and by the short and rounded tip of the ectal division (ECD) of the retrolateral tibial apophysis (Fig. 6).
