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 : 473

Dicronychus diluvii sp. n.

(Figs 47–48, 103–104)

Material examined. Holotype, male: Turkey: “ TURKEY, Prov. Kars, Mts. Ararat, 4.VI.1989, leg. A. Podlussány” ( HNHM). 1 paratype, female: same data as Ht ( HNHM).

Diagnosis. This species is very similar to D. pseudobesus (Orlov, 1993) from Southern Russia in general shape and size, but it can be separated by the pronotum being more arcuate at sides and, above all, by the paramera of the male genitalia and the sclerites of bursa copulatrix.

Description. Male (Fig. 47). Entirely black with antennae and legs yellow ferruginous; covered with dense yellowish pubescence.

Head with eyes a little narrower than anterior margin of pronotum, frons flat between eyes, slightly impressed before anterior margin, this regularly arcuate; punctures coarse, of variable diameters, with very short intervals or subcontiguous.

Antennae exceeding posterior angles of pronotum by length of one antennomere, moderately serrated from third antennomere on; second subcylindrical, less than twice longer than wide; third conical, 1.4× longer than second and twice longer than wide; fourth to tenth subtriangular, on average more than twice longer than wide, last slightly longer than penultimate, subellipsoidal and asymmetrically constricted at apex.

Pronotum slightly wider than long, widest slightly behind middle, strongly and regularly convex, abruptly sloping at sides and base; sides strongly arcuate, from behind middle narrowing forward to apex and backwards to posterior angles, latter slightly divergent, shortly carinate; lateral margin fine and obsolete from midldle; puncturation uniformly distributed, punctures simple, of variable diameters, regularly mixed with very short, shiny intervals.

Scutellum heart-shaped, as long as wide, emarginate at middle of base, impressed at middle and very finely pnctured. Elytra 2.65× longer than pronotum and a little wider than it, very convex; sides subparallel from base to middle, further gradually narrowing; striae regularly marked and punctured, interstriae flat, densely and more finely punctured.

Claws dentate in basal half.

Aedeagus as in Fig. 103.

Female (Fig. 48). Very similar to male with more convex body and shorter antennae not exceeding posterior angles of pronotum.

Bursa copulatrix sclerified as in Fig. 104 .

Size. Length 7–7.3 mm; width 2.25–2.31 mm.

Etymology. The specific epithet refers to the Biblical great flood (diluvium), as the type specimens were collected on Mount Ararat, where Noah’s Ark came to rest after “the Deluge”.
