Epigyne and spermathecae ( Figs 61–62 ). 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 ) and the different configuration of S and SO (cf. Figs 60 & 62 ). 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).
