Németh, T. & Platia, G., 2014, On some Palaearctic click beetles deposited in the Hungarian Natural History Museum, 2 (Coleoptera: Elateridae) *, Zootaxa 3841 (4), pp. 451-490 : 480-481

Dicronychus povolnyi sp. n.

(Figs. 61–62, 124–127)

Material examined. Holotype, female: Afghanistan: “O. Afghanistan, Prov. Nengrahar D. Povolný et coll. (114) Jalalabad 3. 5. 1967 580” ( HNHM). 5 paratypes, 1 male and 4 females: “O. Afghanistan, Prov. Nengrahar lgt. D. Povolný Jalalabad I.–III. 1965 ” (1 male, HNHM); “NO. Afghan. 1953 J. Klapperich Nuristan, Kamu, Bashgultal, 1500 m 24.IV. “ (1 female, HNHM, 2 females, CPG); same but “ 26.IV. ” Cardiophorus (Platynychus) sp. Gurjeva det. 1971 (1 female, HNHM).

Diagnosis. This species is very similar to Cardiophorus hauseri Schwarz, 1900 , it can be separated by the claws being dilated basally and by the genitalia.

Description. Female (Fig. 61). Colour variable; holotype and two paratypes with head and pronotum brownish, darker than scutellum and elytra yellow-ferruginous with blackish undefined shadings, other three paratypes with darker colours, elytra nearly entirely blackish or with reddish base; antennae and legs yellowish; covered with very dense, fine, yellowish pubescence.

Frons flat or moderately convex, anterior margin moderately thickened and regularly curved; punctures very dense, nearly contiguous, approximately of same diameters.

Antennae not reaching posterior angles, very slightly serrated from third antennomera on; second subconical, 3× longer than wide, fourth–tenth subtriangular, on average more 3× longer than wide, last as long as penultimate, subellipsoidal.

Pronotum slightly wider than long, widest before anterior third, strongly convex, abruptly sloping at sides, nearly verically at base; sides arcuate, from just behind anterior third gradually narrowing forwards, less gradually converging backwards, slightly sinuate before posterior angles, latter short, truncate, slightly divergent, shortly carinate; lateral margin well apparent, obsolete only slightly before anterior margin; puncturation double, very fine punctures regularly mixed with larger, deep and simple ones (on average 3–4 smaller punctures falling to one larger).

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

Elytra 2.5× longer and slightly wider than pronotum at middle, convex, widest at middle; striae deeply punctured; interstriae subconvex, very finely punctured.

Claws dentate.

Bursa copulatrix sclerified as in Fig. 124 , asymmetrical piece with a circular base as in Fig. 125 , furca as in Fig. 126 .

Male (Fig. 62). Very similar to female, a little smaller with longer antennae nearly reaching apicies of posterior angles of pronotum.

Aedeagus as in Fig. 127 (length 0.92 mm).

Size. Length 5.6–6.6 mm; width 1.68–2.12 mm.

Etymology. This species is dedicated to Czech lepidopterist Dalibor Povolný, the collector of the holotype.
