Cardiophorus tenuis sp. n.

(Figs 43–44, 98–100)

Material examined. Holotype, female: Armenia: “Kaukas Leder coll. Reitter”. Cardiophorus sp. von Hayek, 1971 ( HNHM). Three paratypes, 1 female and 2 males: same data as holotype (1 male, 1 female, CPG); “Caucasus, Araxesthal, Leder Reitter” concolor Desb. (1 male, HNHM).

Diagnosis. This small species is very similar to Dicronychus rubripes (Germar, 1824) by general outline and colour, but clearly differs in having simple claws and different sclerites on the bursa copulatrix.

Description. Female (Fig. 43). Entirely black with antennae and legs brownish, covered with dense, yellowish pubescence.

Frons flat, slightly impressed at anterior margin, latter moderately thickened, sharply arcuate, puncturation dense, punctures of about same size, deep, simple, with very narrow, shiny intervals.

Antennae ending before posterior angles of pronotum with length of about one antennomere, slightly serrated from third antennomere on; second subconical, 1.6× longer than wide, third-tenth subtriangular, on average 1.7× longer than wide, last slightly longer than penultimate, subellipsoidal.

Pronotum as long as wide, widest at middle, regularly and strongly convex, abruptly sloping at sides and base; sides arcuate, from middle regularly converging anteriorly and posteriorly, slightly sinuate before posterior angles, these truncate, not divergent, shortly carinate; lateral margin very fine, obsolete after middle; puncturation regularly distributed, punctures deep, simple, approximately of same size, with intervals on average equal to their diameters or a little larger.

Scutellum heart-shaped, as long as wide, moderately emarginate at middle of base, slightly impressed at middle, finely punctured.

Elytra 2.5× longer than and as wide as pronotum, convex; sides widest just behind middle; striae well marked, deeply punctured; interstriae moderately convex with finer punctures.

Claws simple.

Bursa copulatrix sclerified as in Fig. 98, furca as in Fig. 99.

Male: (Fig. 44).Very similar to female but with longer antennae exceeding by one antennomere posterior angles of pronotum.

Aedeagus as in Fig. 100.

Size. Length 4.75–6 mm; width 1.43–1.81 mm.

Etymology. The specific epithet was given by O. Schwarz as a manuscript name.
