Type Material. Holotype (male): Panama: Panama Province, Rio Mamoni at PanAm Hwy , black light, 9° 8' N, 79° 4' W, 1 ix 2006, W. D. Shepard and D. Post ( SEMC) . Paratypes (2): Honduras: Rio Humuya NW Comayagua, 14° 29' N, 87° 39' W, 3 viii 1967, O. S. Flint, Jr. (1 USNM) ; Panama: Chiriqui, Rio Vigui (Pan-Amer. Hwy), 8° 12' N, 81° 34' W, 28 ix 1976, Edward S. Ross (1 CAS) .

Differential Diagnosis. The habitus of this species ( Fig. 42) is very similar to that of other members of the Costatus group; reliable determinations will be based on examination of the aedeagus. The aedeagus is similar to that of E. costaricensis in general proportions and size ( Figs. 46, 47); differing therefrom in the shape and degree of sclerotization of the median lobe, which is slightly widened in the distal one-third, and has the margin indented slightly at each pore.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.34/0.69; head (width) 0.38; pronotum 0.52/0.52; elytra 0.83/0.69. Habitus and sculpture as illustrated ( Fig. 42). Head black, dorsum red, venter and coxae dark brown, maxillary palpi testaceous. Eye with ca. 3–4 facets between canthus and posterior margin. Elytra with elongate granules linking punctures. Metaventral depression small.

Etymology. Named in reference to the conspicuous micropores of the median lobe of the aedeagus.

Distribution. Currently known from Panama and Honduras ( Fig. 134).
