Type Material. Holotype (male): Guatemala: El Progresso , km. 69 on C. A. 9, 14° 51' N, 90° 4' W, 2 vii 1974, W. E. Steiner ( USNM). GoogleMaps

Differential Diagnosis. The habitus of this species ( Fig. 57) is very similar to that of other members of the Costatus group; reliable determinations will be based on examination of the aedeagus. The aedeagus ( Fig. 61) has very distinct parameres, wide basally, and in the distal one-fifth markedly narrowed and abruptly arcuate. The median lobe is somewhat similar in shape to that of E. lobilatus ( Fig. 53), but in E. acuminatus it is longer, more nearly parallel-sided; also, the two differ internally, as illustrated. The parameres markedly differ in the two species.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.69/0.84; head (width) 0.47; pronotum 0.64/0.64; elytra 1.08/0.84. Habitus and sculpture as illustrated ( Fig. 57). Head black, dorsum red, venter and coxae dark brown, maxillary palpi testaceous. Eye with ca. 3–4 facets between canthus and posterior margin. Protibiae not arcuate. Elongate granules linking most elytral punctures. Metaventral depression moderately deep, ca. eight granules along base.

Etymology. Named in reference to the acuminate apices of the parameres.

Distribution. Currently known only from the type locality in Guatemala ( Fig. 145).
