Epimetopus oaxacus , new species

Figs. 60 (habitus), 64 (aedeagus), 135 (map)

Type Material. Holotype (male):: Mexico: Oaxaca, Tapanatepec , 8 mi. W Oaxaca, elev. 122 m, 16° 22' N, 94° 12' W, 10 vii 1953, Univ. Kans. Mex. Expedition ( SEMC).

Differential Diagnosis. The habitus of this species ( Fig. 60) 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 a median lobe shaped somewhat like that of E. spatulus ( Figs. 20, 64), but the basal part, between the striate collar and the base, is wider and much shorter. The parameres and basal piece differ markedly in the two species.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.63/0.86; head (width) 0.47; pronotum 0.66/0.67; elytra 1.09/0.86. Habitus and sculpture as illustrated ( Fig. 60). Head black, dorsum brown to reddish brown, venter reddish brown. Eye with ca. 4–5 facets between canthus and posterior margin. Elytra with elongate granules linking punctures. Metaventral depression very small.

Etymology. Named in reference to the geographical distribution.

Distribution. Currently known only from the type locality in Mexico ( Fig. 135).
