Epimetopus transversus , new species

Figs. 8 (habitus), 12 (aedeagus), 127 (map)

Type Material. Holotype (male): Bolivia: La Paz, Alcoche, lamping, elev. 600 m, 15° 45' S, 67° 40' W, 19 xii 1966, Balough, Mahunka, Zicsi (493 Soil Zoological Exp.) ( HNHM) . Paratypes: Same data as holotype (12 HNHM) .

Differential Diagnosis. The habitus of this species ( Fig. 8) 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 ( Fig. 12) has a median lobe somewhat similar in general shape to that of E. transversoides ( Fig. 15), but it is much longer and apically is shaped differently. The parameres are similar in shape in the two species, but in E. transversus they are longer compared to the length of the basal piece.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.65/0.81; head (width) 0.44; pronotum 0.59/0.60; elytra 1.10/0.81. Habitus and sculpture as illustrated ( Fig. 8). 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. Elytral punctures linked by elongate granules. Metaventral depression moderately deep, ca. eight granules along base.

Etymology. Named in reference to the transverse apex of the median lobe of the aedeagus.

Distribution. Currently known only from the type locality in Bolivia ( Fig. 127).
