Figs. 35 (habitus), 40 (aedeagus), 128 (map)

Type Material. Holotype (male): Panama: Canal Zone , 4.1 mi NW Gamboa, Rio Frijoles, flood debris and wet leaves along river, 9° 9.1' N, 79° 44.2' W, 19 ii 1976, A. Newton ( MCZ) . Paratype: Same data as holotype (1 MCZ) .

Differential Diagnosis. The habitus of this species ( Fig. 35) 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. 40) is very broad and stout; it cannot be confused with any others.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.55/0.78; head (width) 0.45; pronotum 0.58/0.59; elytra 1.01/0.78. Habitus and sculpture as illustrated ( Fig. 35). Head black, dorsum red, venter and coxae dark brown, maxillary palpi testaceous. Eye with ca. 4–5 facets between canthus and posterior margin. Protibiae slightly arcuate. Many elytral punctures not linked by granules. Metaventral depression moderately deep, ca. eight granules along base.

Etymology. Named in reference to the very wide and stout aedeagus.

Distribution. Currently known only from the type locality in Panama ( Fig. 128).
