Type material. Holotype, ♂ ( ZIN), “SW Iran, Lorestan province, 20 km N Pol-e Dokhtar, Baba Zeyd vill., 2.V.2007, A.A. Klimenko leg.”.

Etymology. The new species is named after Alexey A. Klimenko (1970–2017), a famous collector of beetles who presented the type material of the new species for this study.

Description. Body length 6.8 mm from anterior margin of frontal projection to elytral apices and 8.4 mm to abdominal apex. Body elongate, with full body length 3.6 times as long as wide at humeri, slightly convex dorsally. Head, mandibles, pro- and mesothorax reddish-yellow, head between eyes, frontal projection of head and mandibles apically somewhat darkened; elytra, metathorax and abdominal ventrites 1–7 brown with lighter metepisterna (metanepisterna) and metepimera as well as penultimate ventrite; antennae brownish-yellow, palpi, legs and pregenital segments yellowish. Head, pro- and mesothorax covered with yellowish pubescence and elytra, metathorax and abdominal ventrites (except for pregenital ones) with brownish pubescence.

Head at eyes 1.1 times as wide as anterior margin of pronotum and about as wide as pronotum, clothed with moderately dense, semierect to erect long setae; integument between eyes shiny, strongly punctate, interspaces between punctures mostly smaller than one puncture diameter; upper surface of frontal projection extremely finely rugose and dull. Antennae reaching one-sixth of elytral length; scape moderately robust, widened apically; pedicel small, subtrapezoidal, about as long as broad; antennomere 3 subtriangular, about twice as long as pedicel, with ventroapical angle produced into robust lobe; antennomeres 4–10 pectinate and subequal in length, with ventroapical angles produced into flattened lamellae, each lamella about as long as body of corresponding antennomere; apical antennomere longest, about twice as long as body of penultimate antennomere ( Fig. 3 ).

Pronotum about 1.3 times as wide as long at midline, shining, clothed with moderately dense, semierect to erect long setae and covered with sparse shallow punctures on disc, punctures becoming denser and stronger towards the sides and base; sides of prothorax along lateral margins and posterior angles rugose. Prohypomeron and prosternum moderately densely punctate and covered with long semi-erect setae.

Scutellum about 1.4 times as long as wide, sparsely and shallowly punctate, shiny. Elytra 1.9 times as long as wide combined at humeri, dull; integument uniformly rugose-granulate and clothed with dense, semierect, moderately long setae. Meso- and metathorax ventrally sparsely covered with shallow punctures and sparse semierect, moderately long setae. Legs clothed with moderately dense semierect setae. Abdominal ventrites 1–7 with shallow and rather dense punctures, clothed with dense, semierect, moderately long setae.

Aedeagus as in Figs 9–11 .
