Hemicrepidius rahmei sp. n.

( Figs 2–4 , 71)

Material examined. Holotype, male: Iran: “ IRAN, prov. Fars Persepolis ~ 1200 m, 25–26.V.1999 Ex im. singled leg.: N. Rahmé” ( HNHM).

Diagnosis. A species distinct from all the other congeners of the region by having the short antennae with antennomeres clearly serrated only from fourth antennomere on.

Description. Male ( Fig. 2 ). Shiny; head, pronotum and scutellum black, elytra and antennae dark-brown with ferruginous shadings; legs with femora blackish, tibia and tarsi yellow-ferruginous; covered with dense, long, partially erect, yellow-fulvous pubescence.

Head with eyes narrower than anterior margin of pronotum, frons flat between eyes, slightly impressed before anterior margin, impression almost reaching clypeus at middle; punctures coarse, umbilicate, with very short, shiny intervals.

Antennae ( Fig. 3 ) reaching apices of posterior angles of pronotum serrated from fourth antennomere on; second antennomere subcylindrical, slightly longer than wide, third subconical, slightly longer than second; second and third, taken together, 1.25× longer than fourth; fourth to tenth triangular, gradually slenderer, on average less than twice longer than wide; last longer than penultimate, ellipsoidal.

Pronotum slightly wider than long, widest at apices of posterior angles, moderately convex; sides nearly and gradually tapering from base to apex, slightly sinuate before posterior angles, latter short, truncate, not divergent, with very short and fine carina directed inwards; puncturation irregularly distributed, punctures on the disk deep, simple, with variable, shiny, intervals equal to smaller than puncture diameters, only slightly denser towards the sides.

Scutellum shield-shaped, moderately convex in first half, finely punctured.

Elytra 3× longer than pronotum, a little wider than it, moderately convex; sides subparallel in basal two-thirds then gradually tapering to apices; striae well marked and punctured; interstriae slightly convex, densely punctured with pseudorugose surface.

Prosternal process ( Fig. 4 ) abruptly and immediately bent behind procoxal cavities, not emarginate at apex.

Aedeagus as in Fig. 71.

Female unknown.

Size. Length 9.7 mm; width 2.68 mm.

Etymology. The species is dedicated to the collector, Nikola Rahmé, insect photographer and collector of Buprestidae , Budapest.
