Xantholinus (Helicophallus) brevispinosus sp. n.

( Figs. 75–84 )

Type material. Holotype: ɗ, " Turkey S. Antalya Prov., W-Toros, Geyik Daglari, Pass ENE of Yarpuz, 1500– 1800 m, 2.IV.2004, leg. Donabaur / Holotypus ɗ Xantholinus brevispinosus sp. n. det. V. Assing 2006" (cAss).

Description. Measurements (in mm) and ratios (holotype): AL: 1.89; HL: 1.37; HW: 1.06; PW: 0.98; PL: 1.37; EL: 1.00; EW: 1.19; AW: 1.15; TiL: 0.79; TaL: 0.65; ML: 1.22; TL: 8.5; HL/HW: 1.30; PW/HW: 0.93; PL/PW: 1.40; EL/PL: 0.73; EW/PW: 1.22; AW/EW: 0.96; TiL/TaL: 1.21.

Habitus as in Fig. 75 . External morphology as in X. multispinosus , but distinguished as follows:

Body smaller (see measurements). Head more slender (see ratio HL/HW and Fig. 76 ). Eyes slightly smaller ( Fig. 77 ). Antennae shorter ( Fig. 78 ). Legs, especially tibiae, shorter (see ratio TiL/TaL).

ɗ: aedeagus ( Figs. 79–80 ) smaller; internally with less numerous and shorter spines ( Fig. 81–83 ).

Comparative notes. For distinguishing characters separating X. brevispinosus from X. multispinosus see the description above. From other Helicophallus species occurring in southern Turkey, X. multispinosus is separated as follows:

from X. tauricus (see Fig. 60 ) by smaller size, a larger aedeagus, by more numerous and shorter spines, and by the presence of a distal brush-like cluster of semitransparent spines;

from X. luteipennis (see Figs. 61–62 ) by distally distinctly shorter and less slender spines in the aedeagus;

from X. lividipennis (see figure 98C in Coiffait 1982) by an aedeagus with more numerous spines.

For additional remarks see the comparative notes in the section on X. multispinosus .

Etymology. The name (Lat., adj.) alludes to the relatively short spines in the aedeagus, a character separating this species from the similar X. multispinosus .

Distribution and bionomics. The type locality is situated in Antalya province, southern Anatolia ( Fig. 84 ), at an altitude of nearly 1500–1800 m. Additional bionomic data are not available.
