Palpus (Figs 50–52). CyL 0.52, CyW 0.24, PTiL. 0.31. The cymbium two times longer than wide, widened proximally. The ST is seen in ventral view. The tegulum elongated, its projections overhang the alveolus. Embolus wide at base, abruptly sharpening at its tip. The membranous PTA does not hide the embolic tip. The PTA with a small distal claw directed retro-laterad. The palpal tibia is considerably shorter than the cymbium. The VTA two times loger than wide, its distal part rounded and membranous prolaterally. The tip of RTA strong, claw-shaped curved ventro-mediad.
Female (the paratype and Russia, Gorno-Altai Republic: nr. Kosh-Agatch): Prosoma light brown, with the pattern of dark brown, white and beige stripes and patches ( Fig. 79 View Figs 67–80 ). Opisthosoma beige, with the light greyish brown and dark brown pattern. Legs strongly dotted, occasionally dots compose stripes. Measurements (n= 2). Body length 4.7–6.05.

Epigyne and spermathecae ( Figs 61–62 View Figs 59–66 ). The epigynal plate ovoid and rounded anteriorly. The CD narrow, the distance between EA is equal to their length. The anterior arch of EA semicircular. The S rounded, narrowing posteriorly. The ID and SO are on the anterior position.
Remarks: This species greatly resembles P. fallax . The male can be distinguished by the embolic shape (more or less straight in P. angulobulbis and almost saddle-shaped distally in P. fallax ) and by the narrower VTA (cf. Figs 50 & 47). The female of P. angulobulbis have the visibly narrower EA (cf. Figs 61 & 59 View Figs 59–66 ) and the different configuration of S and SO (cf. Figs 60 & 62 View Figs 59–66 ).
Habitat: Tuva: dry nanophanerophyte ( Nanophyton erinaceus ) stony steppe (present data). Elevations: 600–2300 m a.s.l.
Distribution: The mountains of South Siberia; for the collection localities see Map 4.
Etymology: The species was named after the angular shape of the tegulum (Fig. 50).
