Xantholinus (Calolinus) marasicus sp. n.

( Figs. 42–48 , 58 )

Type material. Holotype: ɗ, " TR - Kahramanmaraş [8], 30 km SSW K.Maraş, Uzunsöġut, 660 m, 37°23'43N, 36°48'06E, 20.III.2005, V. Assing / Holotypus ɗ Xantholinus marasicus sp. n. det. V. Assing 2006" (cAss). Paratype: ɗ, same data as holotype (cAss).

Description. Measurements (in mm) and ratios (holotype, paratype): AL: 2.14, 1.89; HL: 1.36, 1.31; HW: 1.09, 0.98; PW: 0.98, 0.92; PL: 1.40, 1.31; EL: 0.88, 0.79; EW: 1.10, 1.10; AW: 1.09, 1.07; TiL: 0.83–0.77; TaL: 0.65, 0.59; ML: 1.48, 1.40; TL: 9.3, 8.4; HL/HW: 1.25, 1.34; PW/HW: 0.90, 0.94; PL/PW: 1.43, 1.43; EL/PL: 0.62, 0.60; EW/PW: 1.12, 1.20; AW/EW: 0.99, 0.97; TiL/TaL: 1.28, 1.31.

Habitus as in Fig. 42 . External characters as in X. ibex ( Figs. 42–44 ), but distinguished as follows:

Pronotum paler, dark brown, with the anterior angles reddish. Puncturation of head finer. Pronotum slightly more strongly tapering posteriad. Elytra with finer and less well-defined puncturation and with less smooth interstices. Abdomen with finer puncturation and with more pronounced microsculpture.

ɗ: posterior margins of tergite and sternite VIII weakly convex; aedeagus distinctly longer (see measurements) and more slender, internally with two long series of distinctly sclerotised spines, the left series with very long and slender spines, the right series with more numerous and shorter spines; distally without separate clusters or series of spines or spine-like structures ( Figs. 45–47 ).

Comparative notes. The new species is characterised especially by the distinctive morphology of the aedeagus. Like X. ibex , it is additionally separated from X. rufipennis and X. puthzi by the shorter elytra and the reduced length of the hind wings.

Etymology. The name (Lat., adjective) is derived from the ancient name of the province capital Kahramanmaraş.

Distribution and bionomics. The species is known only from the type locality, which is situated to the southwest of Kahramanmaraş, central southern Anatolia ( Fig. 58 ). The two type specimens were collected by sifting grass roots, moss, and the litter of shrubs on a calcareous slope at an altitude of 660 m ( Fig. 48 ).
