Acantholycosa azarkinae sp. n. Figs 1 –58–1226– 28

Types.

Holotype ♂ and paratypes ♀ (ZMMU) and 1♂ 1♀ (GTS) from Russia, Maritime Province, Lazovski District, Sestra Mt., 43°31'52.23"N, 134°02'49.44"E, 1600 m, scree, 16-23.06.2005 (M.M. Omelko).

Etymology.

The specific name is a matronym in honor of our friend and colleague Galina N. Azarkina.

Diagnosis.

The new species can be easily distinguished from other congeners occurring in the Far East by the shape of the palp, which has a broad embolus tip (Figs 8, 10) (not broad in the other species) and by the shape of the epigyne, which has a broad apical pocket and well developed hoods (Figs 26-28).

Comments.

Acantholycosa azarkinae sp. n. is morphologically close to two other endemic species that occur in the Maritime Province: Acantholycosa oligerae and Acantholycosa sundukovi . The three species have similar male palps although they differ from one another by the shape of the tegular apophysis and the embolus.

Description

(male(female)). Total length 8.0(8.9). Carapace: 3.7(3.6) long, 3.4(3.1) wide. Carapace and abdomen blackish brown, pattern indistinct. Femora I in both sexes with dark semicircles. Males darker than females. Male leg I with dense black hairs on all segments except for tarsus (Fig. 5). Leg II also with hairs but less dense. Carapace/femur I ratio 1.06(1.0). Leg I segments: 3.5(3.6) + 1.5(1.6) + 3.5(3.5) + 3.5(3.2) + 1.7(1.5). Femur I with 2 dorsal, 2 pro- and 2 retrolateral spines; patella with 1 retrolateral spine (0 in female); tibia I with 1 prolateral and 5 pairs of ventral spines (1p, 1r, 5-5v in females); metatarsus with 1 pro-, 1 retrolateral and 2 pairs of ventral spines.

Male palp as in Figs 1-4, 8-12. Cymbium with 3 claws, tegular apophysis without apical arm, palea with laminar outgrowth, terminal apophysis large with claw-like tip; embolic base with small, almost indistinct “spine”, tip of embolus widened and subdivided into two lobes.

Epigyne as in Figs 26-28. Apical pocket wide with two distinct hoods, septum distinct, septum with trapezoidal base; spermathecae long, with blind outgrowth in basal third.
