Leptobium shavrini nov.sp. ( Figs 1-7 )

T y p e m a t e r i a l: Holotype: " Spain (Andalucia) Sierra Magina, near Cortijo de los Prados, 1500 m, 25- 28.03.2010, Shavrin & Anishchenko leg / Holotypus Leptobium shavrini sp. n. det. V. Assing 2010 " (cAss). Paratype: same data as holotype (cSha).

D e s c r i p t i o n: Measurements (in mm) and ratios (holotype, paratype): HL: 1.19, 1.13; HW: 1.13, 1.07; PW: 1.15, 1.03; PL: 1.32, 1.19; EL: 0.93, 0.84; TiL: 1.01, 1.01; TaL: 0.93, 0.82; ML: 1.75, -; TL: 8.3, 7.9; HL/HW: 1.05, 1.06; PW/HW: 1.02, 0.96; PL/PW: 1.14, 1.16; EL/PL: 0.70, 0.71; TiL/TaL: 1.09, 1.23.

Habitus as in Fig. 1 . Coloration of the L. illyricum type: head, pronotum, and abdomen, except for the apex blackish; elytra and abdominal apex (segments VII-X) dark reddish; legs and antennae rufous.

Head moderately oblong (see ratio HL/HW), with sparse and relatively fine punctation; microsculpture absent ( Fig. 2 ); eyes approximately half as long as postocular region ( Fig. 3 ).

Pronotum approximately as wide as head (see ratio PW/HW); punctation similar to that of head, but somewhat less sparse ( Fig. 2 ).

Elytra approximately as wide as, and at suture distinctly shorter than pronotum (see ratio EL/PL); punctation similar to that of pronotum ( Fig. 2 ); microsculpture absent. Hind wings reduced.

Abdomen subparallel, at segment VI 1.05-1.10 times as wide as elytra; punctation dense on anterior tergites, sparse on posterior tergites; integument with shallow transverse microsculpture; posterior margin of tergite VII with very narrow rudiment of a palisade fringe.

Male: sternite VIII posteriorly with cluster of dark setae on either side of middle, posterior margin broadly concave ( Fig. 4 ); sternite VIII with the usual deep and narrow posterior incision, its depth approximately 0.4 times the length of sternite ( Fig. 5 ); aedeagus 1.8 mm long, shaped as in Figs 6-7 , dorsal plate slender and with median carina.

C o m p a r a t i v e n o t e s: The new species is distinguished from the similar sympatric L. castroi by larger size, longer elytra, posteriorly more strongly concave male sternite VII, the more slender male sternite VIII, and by the morphology of the aedeagus (larger size, dorsal plate longer and more slender, ventral process of different shape). For measurements and illustrations of L. castroi see ASSING (2009).

E t y m o l o g y: The species is dedicated to Alexey Shavrin, Irkutsk, one of the collectors of the type specimens.

D i s t r i b u t i o n a n d b i o n o m i c s: The type locality is situated in the Sierra Magina (Jaén, Andalucía, southern Spain) at an altitude of 1500 m, not far from the localities where L. castroi was collected.
