Epigyne and spermathecae ( Figs 18–19 View Figs 16–23 ). The CD wide, narrowing posteriorly. The posterior part of CD concaved as a saddle, its anterior part concaved longitudinally. Two EA well-marked, keyhole-shaped, subparallel; their anterior parts clearly visible in ventral view.

Maps 2–5. Distribution of P. ablegminus (2, asteriks), P. xerophilus (2, dots), P. tuvinensis (3), P. angulobulbis (4) and P. triangulatus (5). One dot may represent more than one close localities

Remarks: This species is most similar to P. histrio and P. xerophilus . Males can be distinguished by the position of the embolus hidden under membranous structures of the bulbus (cf. Figs 7 & 4, 10) and by the shape and position of the PTA, of which tooth is directed laterad (mediad in P. xerophilus , and with two teeth in P. histrio ) (cf. Figs 8 & 5, 11). The females of P. ablegminus can be easily distinguished by the visibly wider CD (cf. Figs 18 & 16, 20 View Figs 16–23 ). The SOs of P. ablegminus are closer to each other (in the median position, as in P. histrio ) than those of P. xerophilus (in the lateral position) ( Figs 17, 19, 21 View Figs 16–23 ).

Habitat: No data. Elevations: 500–600 m a.s.l.

Distribution: A few localities in E Kazakhstan, Map 2.

Etymology: The species epithet is derived from the Latin world ‘ ablegmina ’, which is known from the mythology as the best parts of the sacrificial animal slated for gods.
