Calyptopsis kaszabi sp. nov.

( Figs 1F , 8 D–I)

Type locality. Turkey, Bayburt Province, Bayburt town, 1200 m.

Type material. HOLOTYPE: ♁, ‘ Turchia - vil. Gümüshane Bayburt m 1200 / 1.vii.75 / Osella leg.’ ( HNHM).

Description. Male. Body black, shiny, robust. Apex of frontoclypeus (frontoclypeal tooth) obtuse. Anterior margin of head not separated from the other surface. Lateral margins of head weakly sinuated between genae and frontoclypeus. Lateral margins of genae regularly rounded, not sinuated. Supraocular keels extended almost from level of basal margin of eye. Ratio of width of head at eyes to distance between eyes 1.3. Antennae short, with apical antennomere reaching basal third of pronotum. Ratio of length (width) of antennomeres II–XI: 0.4(0.5): 0.7(0.5): 1.0(0.6): 0.6(0.5): 0.6(0.5): 0.6(0.5): 0.5(0.5): 0.5(0.5): 0.5(0.5): 0.4(0.4). Punctation of head moderately coarse and dense, puncture diameter 1.5× as wide as distance among punctures. Vertex with deep transverse depression, shiny, with coarse and dense rasp-shaped punctation (puncture diameter 1.5–2.0× as wide as distance among punctures). Mentum weakly shiny, with smoothed punctation of weakly rasp-shaped punctures and wrinkles.

Pronotum transverse (1.3× as wide as long), widest in middle, 1.6× as wide as head. Ratio of pronotal width at anterior margin, in middle and at base 4.5: 6.5: 5.5. Anterior margin of pronotum straight, base weakly bisinuate, weakly rounded in middle. Lateral margins of pronotum moderately rounded, straight near base. Anterior angles of pronotum straight, rounded, posterior angles weakly obtuse, narrowly rounded at apex. All margins of pronotum beaded, only anterior margin with interrupted bead in middle. Disc of pronotum moderately regularly convex. Punctation of disc regularly moderately coarse and dense (puncture diameter from subequal to 1.5–2.0× as wide as distance among punctures). Prothoracic hypomera with inner two thirds of surface punctate by rasp-shaped punctures. Prosternum with coarse and dense punctation. Prosternal process moderately convex, not strongly projected, not beaded, with longitudinal impression in middle, with fine and moderately dense punctation.

Elytra oval (1.3× as long as wide), strongly convex, distinctly depressed along suture in anterior quarter, 2.0 × longer and 1.27× wider than pronotum, 2.0 × wider than head. Base of elytra 1.06× wider than base of pronotum. Elytra without microwrinkles, with distinct fine and sparse punctation (puncture diameter 3.0× as wide as distance among punctures). Epipleura wrinkled. Mesoventrite with multiple short regularly rounded bracket-shaped foveae connected by apices. Metaventrite with fine, moderately dense punctation along meso- and metacoxae, remaining surface of metaventrite with smooth sparse punctation. Metepisterna with smoothed coarse punctation.

First and second abdominal ventrite completely beaded, third ventrite beaded on less than half its surface, the other ventrites not beaded. All ventrites with fine, moderately dense punctation.

Legs short. Protibia not fossorial, 3.24× as long as wide. All tibiae straight. Ratio of femur/tibia/tarsus: 4.5: 3.0: 2.0 in fore legs, 4.5: 3.5: 3.0 in middle legs, and 5.0: 4.5: 3.0 in hind legs.

Body length 10 mm, width 4.0 mm.

Etymology. The species is named in honor of the famous specialist on darkling beetles Zoltan Kaszab.

Comparative diagnosis. The new species is most similar to C. pulchella , which also has short roundebracket- shaped foveae on mesoventrite and elytra depressed in basal part along suture, but clearly differs in shiny body ( C. pulchella has dull body), regular, coarse and dense punctation of pronotum ( C. pulchella has coarse and dense punctation only on sides of pronotum), moderately dense distinct elytral punctation ( C. pulchella has very sparse poorly visible elytral punctation).

Distribution. Only known from the type locality.
