Toskina I.N., New and Rare Species of Wood-borer Beetles (Coleoptera: Ptinidae: Ernobiinae, Xyletininae) from Udmurtia // Byul. MOIP. Otd. biol. 2014. T. 119. Vyp. 4. S. 37-42

New and Rare Species of Wood-borer Beetles (Coleoptera: Ptinidae: Ernobiinae, Xyletininae) from Udmurtia

Two new species are described from Udmurtia: Hyperisus varipilosus (subfamily Ernobiinae) and Lasioderma dedyukhini (subfamily Xyletininae) spp. nov. H. varipilosus differs from other palaearctic species of this genus by suberect pubescence (arranged unevenly) and by antennae (the club is longer then 2–8th segments combined together, and segments increase from the 2nd to the 8th). Pronotum 1.45 times as wide as long, lateral margins are flattened. Elytra 1.84 times as long   as wide, surface finely granular and with rather sparse punctation. Pseudopositor: styles 3 times as long as wide, coxites cylindrical, about 3 times as long as thick, paraprocts are as long as coxites. Length 3.5 mm.

L. dedyukhini black, antennae and tarsi light brown. Surface with homogeneous punctation. Eyes round. Antennae: 3rd segment 1.8 times as long as the 2nd one, 4–5th segments smaller than the fol- lowing ones; 6–10th segments with straight apical and lateral margins. Pronotum 1.64 times as wide as long, lateral margins not flattened, pubescence parted to two sides on the middle of the disc. Elytra

1.55 times as long as wide and about 3 times as long as pronotum. Anterior rims of metasternum are approximated and straight in the middle. Fore tibiae not dilated forwards apex. Internal penial sac with two rows (8+10) of small spines, two spines of median size, and one large spine. Length 3.4 mm.

L. dedyukhini differs from other palaearctic black beetles of the genus Lasioderma (L. aterrimum Roubal, 1916; L. obscurum (Solsky, 1867)) by the following characters: it differs from L. aterrimum  by the form of pronotum, antennae, aedeagus (pronotum is campaniform, antennomeres with convex lateral margins, penial sac with 1 row of small spines (Iablokoff-Khnzorian, 1976)    in L. aterrimum).

L. dedyukhini differs from L. obscurum by eyes, antennae, anterior rims of metasternum, aedeagus (eyes shortly oval, antennomeres with convex lateral margin, 2nd anterior rim curved forward, penial sac with 3 rows (6+5+11) of small spines in L. obscurum).

Xyletinus (s. str.) stepposus Toskina, 2006 (described from Volgograd region) and Ptinus (s. str.)

pusillus Sturm, 1837 (known only from West Europe (Zahradník, 2007)) were found in Udmurtia  by

S.V. Dedyukhin. The apex of pseudopositor of X. stepposus can be described as follows: styles almost cylindrical, 3 times as long as thick in the middle. Coxite almost twice as long as style, with apical group of chaetae, obliquely joined up to outside of paraproct. The latter twice as long as coxite and 4 times as long as its thickness at the base; paraproct slightly widened towards base.

X. stepposus from Udmurtia differs from the holotype by surface with coarser punctation and body’s colour varying from black (as in the holotype) to specimens with red or rufous parts of body, specifically specimens with red pronotum and tibiae, tarsi yellow. X. stepposus with red pronotum dif- fers from X. ruficollis Gebler, 1833 also having red pronotum by the following characters. Pronotum  is campaniform, antennal segments with convex lateral margin, 7th antennal segment 1.44 times as wide as long; side processes of distal part of 9th abdominal sternite are finger-shaped, rather long,  and curved inside in X. stepposus. Pronotum is trapeziform, antennal segments with concave lateral margins, 7th antennal segment 1.7 times as wide as long; side processes of distal part of 9th abdominal sternite are short, cuneiform in X. ruficollis.
