Caudal extension of elytra (mucro) distinct, 5 mm long; elytra 4 times as long as mucro. Elytra with rasp-like punctures, punctation at sides becoming denser. Epipleura with fine wrinkles and sparse fine rasp-like punctation. Hair tuft between abdominal ventrites 1 and 2 present. Abdominal ventrites 1–3 with large transverse wrinkles in middle, ventrites 4–5 without wrinkles. Abdominal ventrites 1–3 covered with sparse small granules and rasp-shaped punctures, ventrite 4 with only rasp-like punctures, ventrite 5 with simple punctures, completely beaded except for base.

Legs slender. Ratio of lengths of femora, tibiae and tarsi of fore, middle and hind legs 6.5: 5.5: 3.2; 7.2: 6.3: 4.1; 9.1: 8.2: 4.7. All tarsomeres with bifurcated setal brush.

Anterior margin of male inner sternite VIII weakly emarginate, straight in middle, accessory gland of sternite VIII moderately long and thin, middle of sternite without hairs. Rods of spiculum gastrale merged at apex, forming long common stem, lobes of spiculum gastrale elongated. Aedeagus length 4.3–4.4 mm, width 0.8–0.9 mm. Aedeagus weakly Cshaped. Basal third of lateral margins of parameres almost straight, middle widely round- ed, apical third strongly acuminate at apex. Parameres length 1.4 mm, width 0.5 mm. Sides of parameres with two longitudinal impressions: one longer beginning from base and another shorter and disposed at middles.

Body length 27–28 mm, width 9.7–9.9 mm.

Female. Shape of body and punctation similar to those of male. Head 1.26 times as wide as interocular distance. Antennomeres 10–11 reaching base of pronotum when directed backwards. Ratio of pronotal width near anterior angles, in widest part and at base 3.8: 6.9: 6.4. Elytra elongate (1.72 times as long as wide together), 3.16 times as long and 1.38 times as wide as pronotum, 2.7 times as wide as head. Mucro short (1.6 mm).

Ovipositor moderately long. Apical lobes straight in basal thirds, weakly arcuately rounded in middle, apical third weakly arcuately emarginate. Apex of lobes acute. Anterior margin of proctiger with deep narrow emarginated in middle. Basal duct of spermatheca between vagina and reservoirs long, gland of spermatheca short. Bases of reservoirs of spermatheca thin, their apical half wider, 1st reservoir twice larger than 2nd. Stem of spiculum ventrale moderately long and thin.

Body length 22–24 mm, width 9–9.2 mm.

Etymology. The species is named after the late Nikolay Georgievich Skopin famous specialist on Central Asian Tenebrionidae .

Differential diagnosis. The body shape and punctation of this new species is similar to B. granulata , B. granulipennis and B. tsharynensis . Blaps skopini

sp. n. differs from:

− B. granulata in the more elongate pronotum (pronotum of B. granulata 1.4 times as wide as long); longer mucro of males (male elytra of B. granulata 5.5 times as long as mucro); in contrast to those of Blaps skopini sp. n., the sides of parameres of B. granulata are smooth, without longitudinal impression, slightly and gradually arched to apex (viewing from above), apex of the latter is straight ( Fig. 28B );

− B. granulipennis in the coarser and denser punctation of the pronotum (punctures in Blaps skopini sp. n. are subcontiguous, while in B. granulipennis are subcontiguous everywhere except for middle); longer mucro of males and females (elytra of B. granulipennis 7.9 times as long as mucro); sides of parameres of B. granulipennis are widely rounded to the apex, with obtuse distinct emargination near the apex; lateral sides of apex of parameres are straight and parallel relative to each other ( Fig. 27A );

− B. tsharynensis in the coarser and denser punctation of the pronotum (punctures in Blaps skopini sp. n. are subcontiguous, while they in B. tsharynensis are not contiguous); longer mucro of males and females (elytra of B. tsharynensis 10.5 times as long as mucro); larger and more distinct hair tuft between abdominal ventrites 1 and 2 ( Figs 35B ); parameres of Blaps skopini are elongated (2.48 times as long as wide), while parameres of B. tsharynensis are shorter (1.8 times as long as wide); joined apex of parameres in Blaps skopini sp. n. is thin and long ( Fig. 30 ), while ca, r = reservoirs, g = accessory gland of spermatheca). Scale bars = 1 mm

that in B. tsharynensis is thin, but short; reservoirs of spermatheca of Blaps skopini sp. n. are thin and fusiform, while reservoirs of spermatheca in B. tsharynensis are elliptic; stem of spiculum ventrale of the new species is thinner than that in B. tsharynensis .
