Dicronychus decoroides sp. n.

(Figs 46, 102)

Material examined. Holotype, male: Iran: “ IRAN, Golhak 1400 m bei Teheran, III–V.1961 leg J. Klapperich”. ( HNHM). 1 paratype, male: “Mazandaran prov., Alborz Mts., 15 km E of Lar-e-Polur, 2580 m, 12–13.V.2001, Gy. Fábián & K. Vig” (CPG).

Diagnosis. This species resembles D. decorus (Faldermann, 1836) in general shape and size but can be separated by the less defined yellowish colour of elytra and particularly by the slightly dilated apices of the paramera in the male genitalia.

Description. Male (Fig. 46). Head, pronotum, scutellum blackish, elytra brownish with undefined blackish shadings; antennae and legs yellow-feruginous; covered with dense, rough, yellow-fulvous pubescence.

Frons moderately convex, slightly impressed at anterior margin, moderately thickened, subarcuate or nearly straigth at middle; punctures dense, deep, simple, approximately of same size, with very short and shiny intervals or contiguous.

Antennae exceeding posterior angles of pronotum by about one antennomere, slightly serrate from third antennomere on; second subconical, 2× longer than wide, third to tenth subtriangular, third shorter than following, 1.7× longer than wide, fourth to tenth gradually slenderer, on average 2–2.2× longer than wide, last a little longer than penultimate, subellipsoidal.

Pronotum as long as wide, widest at middle, regularly and strongly convex; sides strongly arcuate, almost equally narrowing forwards and backwards from middle, slightly sinuate before posterior angles, these short, truncate, not divergent; lateral margin very fine and obsolete after middle; puncturation dense and uniformly distributed on all surface; punctures deep, simple, approximately of same size, with very short intervals or contiguous.

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

Elytra 2.4× longer than as wide as pronotum, convex; sides suboval slightly dilated behind middle; striae well distinct and deeply punctured; interstriae subconvex, very finely and densely punctured.

Claws dentate in basal half.

Aedeagus as in Fig. 102 (length 1.12 mm).

Female unknown.

Size. Length 6–7.5 mm; width 1.93–2.18 mm.

Etymology. The specific epithet refers to the similarity to Dicronychus decorus (Faldermann, 1836) .
