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.
