Figs. 51 (habitus), 55 (aedeagus), 136 (map)

Type Material. Holotype (male): Costa Rica: Puntarenas, Monteverde area , 10° 18' N, 84° 50' W, 6–14 vi 1973, Erwin & Hevel ( USNM) . Paratype: Same data as holotype (1 USNM) .

Differential Diagnosis. The habitus of this species ( Fig. 51) 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. 55) has a large, wide median lobe—unlike any other species. The parameres gradually increase in width from base to apex, and slightly arch; each has two small setae apically.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.79/1.00; head (width) 0.53; pronotum 0.67/0.71; elytra 1.20/1.00. Habitus and sculpture as illustrated ( Fig. 51). Head black, dorsum brown to reddish brown, venter dark brown to piceous, legs dark brown. Eye with ca. 3–4 facets between canthus and posterior margin. Elytra with elongate granules linking punctures. Metaventral depression moderately deep and wide, ca. nine granules along base, shallow.

Etymology. Named in reference to the wide median lobe of the aedeagus.

Distribution. Currently known only from the type locality in Costa Rica ( Fig. 136).
