Etymology. The specific name is a patronym in honour of our friend and colleague Dmitri V. Logunov (Manchester) in recognition of his initiation of what became an intensive study of the spider fauna of Tuva.

Diagnosis. The new species is closely related to P. tesquorum . Males of P. logunovi sp. nov. differ from those of P. tesquorum by having (1) brownish palpal patella with black hairs (cf. Figs 38 & 39), (2) terminal apophysis slightly wider and less angled (cf. Figs 42 & 43), and (3) basally directed paleal process more curved (cf. Figs 48 & 50). Females are distinguishable from those of P. tesquorum by the bulging structure in the epigyne visible in dorsal view (Fig. 56, arrow) and by the arrangement of folds forming this bulging structure (cf. Figs 63 & 65).

Description. Male (holotype). Total length 5.8. Carapace 3.00 long, 2.20 wide.

Prosoma. Carapace (Fig. 32) dark brown with narrow yellowish median band in thoracic part. Lateral bands commonly not traceable but may be lighter but indistinct, anteriorly broken into spots. Thoracic part with short dark pubescence. Clypeus yellowish brown, notably below ALEs, and furnished with dark hairs. Chelicerae yellowish-brown with darker longitudinal streaks, mesally yellow; furnished with dark hairs; retromargin with 2 teeth. Sternum dark greyish with narrow yellowish stripe anteriorly and furnished with light hairs.

Eyes. Width of row I 44 (slightly procurved when seen from in front), row II 68, row III 88, row II-III 65. Diameter of AME 9, ALE 8, PME 24, PLE 19. Distance between AMEs 7, between AME and ALE 2.

Opisthosoma. Dorsum (Fig. 32) with light greyish-brown lanceolate stripe anteriorly followed by a series of transverse dark bars, each bar between a white-haired spot at each side. Between bars paired yellowish spots (often confluent), each spot with a dark dot in middle. Venter brown. Sides of dorsum and venter with dense, recumbent whitish pubescence.

Legs (Table 1). Rather thin, yellow, with weak, slightly darker markings and annulation. Leg I without deviant pilosity.Ti I with 2 retrolateral spines.

Palp (Figs 36, 38, 40, 42, 44-45, 48-49). Pt 0.60, Ti 0.55, Cy 1.30. All segments dark brownish, more or less suffused with black, and with dark pubescence (Figs 36, 38). Tegular apophysis stout, rugose, curved retrolaterad, with small hooked process at base (Fig. 49). Basally directed paleal process distinctly curved (Figs 44, 48). Terminal apophysis sclerotized, flattened, blunt at tip (Figs 42, 45). Embolus laminar, grooved along its length, ventral edge turned forwards along two thirds of embolus length, then abruptly narrowing.

Female (allotype). Total length 7.5. Carapace 3.30 long, 2.55 wide.

Prosoma and opisthosoma. Coloration lighter, with more contrasting pattern compared to the male. Carapace (Fig. 33) with bright yellow median band, wider than in the male and continuing into postocular area; yellow lateral bands broken into distinct spots. Bands with whitish pubescence. Clypeus yellowish. Chelicerae yellowish with brown veins, furnished with dark and whitish hairs; retromargin with 2 teeth. Opisthosoma (Fig. 33) patterned as in the male, lanceolate stripe and spots between dorsal dark bars yellowish; venter yellowish brown.

Eyes. Width of row I 49 (slightly procurved when seen from in front), row II 70, row III 93, row II-III 67. Diameter of AME 10, ALE 9, PME 26, PLE 22. Distance between AMEs 8, between AME and ALE 3.

Legs (Table 1). Yellowish, with more distinct dark markings than in the male.

Epigyne (Figs 52-53, 56, 59-60, 63-64). Septal ridge of varying width, extending approximately one-half epigynal length, anteriorly with two transversal pockets. Cavity wide, divided by widened septum. Lateral margins of epigynal plate deeply indented, clearly visible in dorsal view (Fig. 63, arrow).

Size variation. Carapace length: males 2.65-3.00 (n=10), females 2.75-3.30 (n=10).

Habitat. In Mongolia, this species was collected on a pebbly lake shore and along a river bank. In Tuva, in habitats near streams.

Distribution (Fig. 117). Mongolia and Russia (Altai and Tuva). It is very likely that this species may occur in adjacent Xinjiang. Records of P. tesquorum from Inner Mongolia (cf. Song et al. 1999: 334) likely refer to this species.
