Epimetopus lobilatus , new species

Figs. 49 (habitus), 53 (aedeagus), 146 (map)

Type Material. Holotype (male): Costa Rica: Limon, Reventazon, Hamburg Farm , at light, 10° 15' N, 83° 28' W, 25 v 1931, F. Nevermann ( FMNH) . Paratypes: Same data as holotype, except 28 ix 1934, F. Nevermann (2 FMNH) .

Differential Diagnosis. The habitus of this species ( Fig. 49) is very similar to that of other members of the Costatus group; reliable determinations will be based on examination of the aedeagus. The aedeagus has parameres that are lobate apically, as does E. costaricensis ; however, the paramere lobes are shaped differently in the two species ( Figs. 47, 53). Also, the median lobe of E. lobilatus tapers in the distal one-half, whereas in E. costaricensis the median lobe is virtually parallel-sided. The median lobe of E. lobilatus is more similar in shape to that of E. apocinus , but in that species the parameres are narrowed apically, not lobate.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.32/~1.00; head (width) 0.55; pronotum 0.75/0.77; elytra 1.33/~1.00. Habitus and sculpture as illustrated ( Fig. 49). Head black, dorsum red, venter and coxae dark brown, maxillary palpi testaceous. Eye with ca. 3–4 facets between canthus and posterior margin. Protibiae slightly arcuate. Elytra with elongate granules linking punctures. Metaventral depression moderately deep, ca. six granules along base.

Etymology. Named in reference to the wide apical lobes of the aedeagal parameres.

Distribution. Currently known only from the type locality in Costa Rica ( Fig. 146).
