Epimetopus arizonicus , new species

Figs. 66 (habitus), 70 (aedeagus), 138 (map)

Type Material. Holotype (male): USA: Arizona, Pajarito Mts. , Sycamore Cyn., 31° 56' N, 110° 48' W, 24 viii 1968, [no collector on label] ( MCZ) . Paratypes: Same data as holotype (4 MCZ) .

Differential Diagnosis. This is a markedly granulate species, with dark brown dorsum; otherwise the habitus ( Fig. 66) 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 long median lobe, which is slightly widened at about the distal one-third; it is probably related to E. costatus , which see for comparisons ( Figs. 70, 71).

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.79/0.94; head (width) 0.50; pronotum 0.64/0.69; elytra 1.20/0.94. Habitus and sculpture as illustrated ( Fig. 66). Head black, dorsum brown to reddish brown, venter and legs dark brown, maxillary palpi brown. Pronotal and elytral granules prominent, including elongate granules linking punctures. Eye with ca. 3–4 facets between canthus and posterior margin. Protibiae stout, flattened in distal 1/5, outer margin arcuate, inner margin straight. Metaventral depression moderately deep and wide, ca. eight granules along base.

Etymology. Named in reference to the geographical distribution.

Distribution. Currently known only from the type locality in Arizona ( Fig. 138).
