Type Material. Holotype (male): Peru : Pantiacolla Lodge , Monk Saki Trail , Alto Madre de Dios River, at black light, elev. 400 m, 12° 39' S, 71° 13' W, 25 x 2000, R. Brooks ( PERU 1B00 098A) ( SEMC) GoogleMaps   . Paratypes (42): Peru: Same data as holotype (32 SEMC) GoogleMaps   ; Madre de Dios, Hostel Erica (near Salvacion), elev. 550 m, 12° 53' S, 71° 14' W, 3–5 ix 1989, R. A. Faitoute et al. (10 USNM) GoogleMaps   .

Differential Diagnosis. The habitus of this species ( Fig. 11) is very similar to that of several other members of the Costatus group; reliable determinations will be based on examination of the aedeagus. The aedeagus could be compared with that of E. transversus   ( Figs. 12, 15); however, the median lobe is shaped differently, considerably smaller in E. transversoides   , and the internal sac is different in extent and sculpture in the two species, being narrower and with denser spicules in E. transversoides   .

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.36/0.69; head (width) 0.41; pronotum 0.52/0.51; elytra 0.89/0.69. Habitus and sculpture as illustrated ( Fig. 11). Head black, dorsum brown to reddish brown, venter and coxae dark brown. Eye with ca. 4–5 facets between canthus and posterior margin. Elytra with elongate granules linking punctures. Metaventral depression moderately deep, ca. eight granules along base.

Etymology. Named in reference to the similarity of the aedeagus to that of E. transversus   .

Distribution. Currently known only from Peru ( Fig. 128).
