Figs 5, 6View FIGURES 1 – 8, 9–11View FIGURES 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. 5View FIGURES 1 – 8), by the presence of a lateral tooth-like projection on the dorsal division (DD) of the median apophysis ( Figs 9, 10View FIGURES 9 – 11) and by the short and rounded tip of the ectal division (ECD) of the retrolateral tibial apophysis ( Fig. 6View FIGURES 1 – 8).

Description. Male (Holotype, San Pablo, San Pedro, Colombia, MCTP 8869). Total length 7.63. Carapace 3.75 long, 2.82 wide, light brown, darker laterally; small dark brown bristles laterally; fovea with dark mark. Clypeus light brown, 0.30 high.

Chelicerae reddish-brown, with small light brown setae; lateral carina conspicuous, depressed distally, near the fangs; promargin and retromargin of fang furrow with three teeth equidistant and equal in size.

Ventral pairs of macrosetae on tibiae: I- 4; II- 4; III- 3; IV- 3. Superior tarsal claw with eight teeth and inferior tarsal claw with one tooth ( Fig. 11View FIGURES 9 – 11). Abdomen 3.98 long, grayish, dorsum with a median light brown band and two pairs of sigilla. Venter grayish, with scattered setae. Palpus with a prominent and acute guide (G) on the dorsal division of the median apophysis ( Fig. 5View FIGURES 1 – 8).
