Type material. Holotype: ALBANIA: Zepës Mts., Lar env., 1600 m, 8.VI.2014, ♂, P. Moravec leg. (PCJM). Paratypes: ALBANIA: Zepës Mts., Lar env., 1600 m, 8.VI.2014, 1 ♀, P. Moravec leg. (PCJM); dtto, 1 ♂, 1 ♀, P. Vonička, P. Moravec et L. Blažej leg. (PCPB).
Diagnosis. Dima vonickai sp. nov. belongs to the group of species with more convex, suboval-shaped body and shiny elytral intervals with very sparsely distributed thin setae (Fig. 114–115). This species is like D. fialai sp. nov., D. dusaneki sp. nov. and D. raineri based on the pubescence of the pronotal lateral margin, which is short, almost decumbent in anterior part and longer, semi-erect posteriorly (Fig. 161). Dima fialai sp. nov. and D. dusaneki sp. nov. differ from D. vonickai sp. nov. by more robust body, wide and convex pronotum (Figs 20–21, 29–30), and shorter apical lobe of paramera (Figs 181, 184). Dima raineri has pronotal punctures of two different sizes (almost the same size in D. vonickai sp. nov.; Figs 154–155, 161) and differently shaped paramera (Figs 210– 213, 220).
Description. Holotype, male. Body medium-sized, 12.5 mm long, 5.1 mm wide, shiny, covered with short dense pubescence on pronotum and sparse on elytra. Body black, with paler, reddish-brown legs, antennae, elytral sutura and margins; pubescence yellowish (Fig. 114).
Head including eyes 0.6 times as wide as pronotum, frons with shallow v-shaped depression; punctation sparse and coarse, intervals between punctures shiny; pubescence on head semi-erect, more erect in anterior part of frons, directed forwards. Supraantennal carina weakly developed, short. Antennae moderately long, surpassing the posterior angles of pronotum of about 3.5 segments; antennomeres II and III subtriangular, more than 1.5 times longer than wide, subequal, together about 1.4 times longer than antennomere IV, length ratio of antennomeres II– IV 1.0: 1.0: 1.4, antennomeres IV to X gradually widened apically, less than 2 times longer than wide, apical antennomere longest, subacute apically; surface of antennomeres covered with moderately long, semi-erect setae.
Pronotum 1.4 times wider than long, widest just behind middle, moderately convex dorsally; sides convex; anterior angles obtuse; posterior angles prominent, sharp, slightly produced outward; punctation sparse, moderately fine, punctures on disc equally distributed, of about the same size; intervals between punctures of 2–3 times a diameter of puncture, flat, shiny. Pubescence on pronotal disc moderately dense, short, decumbent; that on pronotal sides in anterior two thirds decumbent, in posterior third semi-erect; setae in hind angles long, erect (Fig. 161). Prosternum finely, sparsely punctate, interstices glabrous, with short decumbent to semi-erect setae, denser at margins; prosternal lobe moderately coarsely punctate, with longer semi-erect pubescence.
Scutellum sub-pentagonal, with sides sub-parallel, in lateral view slightly raised above the plane of elytra, widest at two thirds; frontal margin rounded, gradually declined, apex rounded; punctation fine, dense; pubescence fine, short, semi-erect. Elytra suboval, 3.3 times longer than pronotum, convex, widest at posterior two thirds; striae well developed along the whole elytral length, some of them irregularly interrupted by coarse sparse punctures; surface of interstices flattened, shiny, sparsely punctate; punctures shallow, suboval, equally distributed, of the same size; pubescence short, very sparse.
Aedeagus elongate; paramera long, narrow, its apical lobe elongate, subapical tooth subacute (Fig. 220).
Female (Fig. 115). Very like male (in contrast with most other Dima spp.), but more robust, with shorter antennae (surpassing the posterior angles of pronotum about two segments) and slightly wider scutellum. The sclerotized spines of bursa copulatrix as in Fig. 241.
Intraspecific variability. Body length: 10.7–12.3 mm.
Distribution. Albania (Zepës Mts.; Fig. 244).
Etymology. The specific epithet is a patronym in honor of Mr. Pavel Vonička (Liberec, Czech Republic), who collected a part of the type series.
