Berlandina yakovlevi sp. n.

Figs 83–93

Material: MONGOLIA, Khovd Aimag: holotype ♂ ( ISEA) and paratypes 16♂♂ 1♀ ( ISEA), 23 km SW from Uench Village, Uenchiyn-Gol River Valley, 45º54’N, 91º50’E, sandy desert, night, attracted by light, 1200 m, 13– 14.05.2012 (AF); 1♂ ( ZMMU), 33 km SW from Altai Village, Bodonchiyn-Gol River Valley, 45º46’17”N, 92º12’52”E, stony desert, 1300 m, 6–7.05.2012 (AF).

Etymology. The specific name is a patronym in honour of our friend, entomologist Roman V. Yakovlev (Barnaul, Russia) who organized an expedition to Mongolia in which new Berlandina species were collected.

Diagnosis. This species is larger than all congeners in Asia. The new species is most similar to B. saraevi and B. nakonechnyi sp. n. From the former species it differs by having a distinct abdominal pattern ( Figs 73 and 90 ), and abrupt tip of the embolus. For differences with the latter species see the diagnosis in B. nakonechnyi sp. n.

Description. Male. Total length 10.7. Carapace: 5.3 long, 4.1 wide. Coloration: carapace yellow with gray stripes formed by gray hairs on the sides of cephalic part. Legs and palps yellow. Tibiae-tarsi of legs I and II with long hairs ( Fig. 90 ). Labium, maxillae and sternum brown. Chelicerae dark brown. Abdomen and spinnerets beige. Abdomen with gray cardiac mark dorsally and two longitudinal gray stripes.

Spination of leg IV: femur: d1-1-1, p0-1-1, r0-1-1; patella: p1-0, r1-0; tibia: d1-0-0, p1-3(1)-1, r1(2)-1-1, v2-2 - 2; metatarsus: d1-2-0, p1-1-0, r1-1-0, v2-1 (0)-2.

Leg article length.

Palp as in Figs 83–89 ; tibia with ventral lobe and two tibial apophyses: one large, as long as tibia, and second small, poorly pronounced and hidden by the larger one; dorsal part of tibia with 5 strong spines; embolus relatively thin; tip of embolus with small triangle lobe ( Fig. 86 ), dorsal side with two ridges ( Fig. 88 ).

Female. Total length 11.15. Carapace: 4.9 long, 3.65 wide. Coloration as in male. Spination of leg IV: femur: d1-1-1, p0-1-1, r0-0-1; patella: p1-0, r1-0; tibia: d1-0-0, p1(2)-1-1(2), r1-1-1(2), v2-2 -2; metatarsus: d1-2-0, p2(1)-1-0(2), r1-1-0, v2-1 -2.

Leg article length.

Epigyne as in Figs 91–92 ; with round fovea, wide septum; receptacles closely spaced. Vulva with two pairs of accessorial glands (Ag).

Distribution. Known from the type locality only.
