Diagnosis. The female of A. logunovi can be distinguished from other congeners by the shape of the transverse basal part of the septum and small apical pockets (cf. Figs 3–9 ). The epigyne is similar to that of A. plumalis Marusik, Azarkina & Koponen, 2004 and especially to A. paraplumalis Marusik, Azarkina & Koponen, 2004 , but can be separated from that of A. plumalis ( Figs 5–6 ) by the less widely separated lateral margins (Lm) and a straighter apical margin (Um) of the fovea, and from A. paraplumalis ( Figs 7–9 ) by the shape and proportions of the fovea and septum. Males of this species can be separated from other congeners by the spine-shaped apical arm of the tegular apophysis and thin embolus.

Description. Total length 8.4–11.0. Carapace: 3.7–4.1 long, 3.0–3.3 wide. Carapace dark brown, sometimes with light spot in front of the fovea. Sternum dark brown. Abdomen dark grey, almost black dorsally and dirty yellow ventrally. Legs brown with yellowish spots and bands. Coxae dirty yellow ventrally. Leg I joints (specimen with carapace 3.7 long): 3.45+1.65+3.25+3.0+1.5. Femur I with 3 dorsal, 3 pro- and 2 retrolateral spines. Patella I with 1pro- and 1 retrolateral spines. Tibia I with 5 pairs of ventral (apical not counted), 1 pro- and 1 retrolateral spines. Metatarsus with 2 pairs of ventral, 1 pro- and 1 retrolateral spines.

Epigyne (specimen with carapace 3.9 long). 1.05 high and 1.15 wide. Epigyne as in Figs. 3–4 , with fused apical pockets (Ap). Shape of apical margin of fovea is variable, but usually ^ - shaped. Septum ⊥ - shaped, developed in fovea only. Receptacula (Re) short, shorter than fovea height.

Comments. Marusik et al. (2004) did not place A. logunovi in any species group because males and females were similar to different species groups. Based on the similarity of the female epigyne of this species to those of A. plumalis and A. paraplumalis , and the conformation of the male palp to members of the A. plumalis -group, we conclude that A. logunovi belongs to the A. plumalis -group.

Distribution. This species is known from two localities separated by about 120 km ( Fig. 10 ).
