Diagnosis. Dima zbuzeki sp. nov. is similar in the shape, coloration and pubescence of body, punctation of pronotum and shape of apical lobes of paramera to D. hladilorum (Figs 47–49, 116–118, 137, 162, 190, 221). These species differ in the scutellum, which is wider, flat, and only slightly emarginate basally in D. zbuzeki sp. nov. and narrower, convex, and strongly emarginate basally in D. hladilorum. This species differs from D. fthiotidensis and D. evritaniensis by the shiny pronotum with sparse punctation (Figs 126–127, 130–134, 162) and from D. pelionensis by the pubescence of pronotal lateral margin, which is semi-erect along the whole margin length (Figs 152–153). Dima etoliensis is larger, has longer antennae with longer segments (in females, as no males are known for D. etoliensis) and more parallel-sided elytra (Fig. 25).
Description. Holotype, male. Body small, 9.9 mm long, 4.0 mm wide, moderately shiny pronotum, more matt elytra. Body brown, with paler, reddish-brown legs, antennae, elytral sutura and margins; pubescence yellowish (Fig. 116).
Head including eyes 0.6 times as wide as pronotum, frons with shallow depression medially; punctation dense and coarse, intervals between punctures shiny posterad, rugose in anterior part; pubescence on head semi-erect, more erect in anterior part of frons, directed forwards. Supraantennal carina short, indistinct. Antennae moderately longer surpassing the posterior angles of pronotum of about four segments; antennomeres II and III short, subequal, less than 1.5 times longer than wide, together about 1.2 times longer than antennomere IV, length ratio of antennomeres II–IV 1.1: 1.0: 1.8, antennomeres IV–X gradually widened apically, about 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 at middle, moderately convex dorsally; sides slightly and evenly convex, anterior angles obtuse; posterior angles prominent, sharp, slightly produced outward; punctation moderately dense, coarse, punctures on disc equally distributed; intervals between punctures moderately shiny. Pubescence on pronotal disc moderately long, semi-erect; that on pronotal sides semi-erect along the whole length, gradually longer towards posterior angles, longest and erect in posterior angles (Fig. 162). Prosternum finely, moderately sparsely punctate, with short semi-erect setae; prosternal lobe moderately coarsely punctate, with long semi-erect pubescence.
Scutellum sub-pentagonal, flattened, slightly depressed medially, in lateral view slightly above the plane of elytra, widest at middle; frontal margin slightly emarginate, gradually declined; apex widely rounded, punctation sparse, coarse; pubescence fine, moderately long, semi-erect. Elytra sub-parallel, 3.4 times longer than pronotum, moderately convex, widest behind middle; striae well developed in 4/5 of elytral length, interrupted irregularly at apical part with coarse sparse punctures; surface of interstices flattened, slightly matt, densely and finely punctate; punctures suboval, equally distributed, of the same size.
Aedeagus elongate; paramera long, narrow, its apical lobe long, narrow, subapical tooth robust, obtuse (Fig. 221).
Female (Fig. 117). Like male but slightly paler, suboval, antennae shorter (about 2.5 segments surpassing posterior angles of pronotum), pronotum wider, 1.5 times wider than long, widest at middle. The sclerotized spines of bursa copulatrix as in Fig. 242.
Intraspecific variability. Body length: 9.0– 11.5 mm. Body coloration is light brown in some specimens (Fig. 118).
Distribution. Greece (Agrafa Mts.; Fig. 245).
Etymology. The specific epithet is a patronym in honor of Mr. Bořivoj Zbuzek (Praha, Czech Republic), who collected a part of the type series.
