Type Material. Holotype (male): Ecuador: Napo, 17 km SW Tena , 1° 4' S, 77° 49' W, 28 v 1977, W. E. Steiner ( USNM) GoogleMaps   . Paratypes (3): Misahualli , 1° 2' S, 77° 40' W, 9 xi 1987, M. Huybensz (1 MCZ) GoogleMaps   ; Sta. Cecilia, at whitelight, 0° 2' N, 76° 58' W, 16 v 1975, Ashley B. Gurney (1 USNM) GoogleMaps   ; Tena , 0° 59' N, 77° 49' W, 27 v 1977, W. E. Steiner (1 USNM) GoogleMaps   .

Differential Diagnosis. The habitus of this species ( Fig. 17) 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 is somewhat similar to that of E. hintoni   ( Figs. 13, 21). However, the median lobe is slightly wider than that of E. hintoni   , whereas the parameres, in both views, are narrower. The median lobe internal structures also differ in the two species, as illustrated.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.56/0.75; head (width) 0.40; pronotum 0.56/0.57; elytra 1.01/0.75. Habitus and sculpture as illustrated ( Fig. 17). Head black, dorsum red, venter and coxae dark brown, maxillary palpi testaceous. Eye with ca. 4–5 facets between canthus and posterior margin. Elytra with distinct granules linking punctures. Protibiae slightly arcuate. Metaventral depression moderately deep, ca. eight granules along base.

Etymology. Named in reference to the geographical distribution.

Distribution. Currently known from Ecuador ( Fig. 127).
