488683F9FE325F098DAD74B1BF0D2E5A.taxon	diagnosis	Diagnosis. Among the species of the subgenus Exanthidium Pasteels, 1969 (Kasparek 2021), the male of P. astafurovae is unequivocally characterised by the following combination of characters: i) tergum 6 laterally bulging, without hooked or spiniform protrusion (Fig. 3 D); ii) emargination of tergum 7 little widening in apical third, with rather pointed base (emargination V-shaped) (Fig. 3 D); iii) emargination of tergum 7 with translucent margin (Fig. 3 D); iv) posterior margin of scutellum rather rounded in dorsal view (Fig. 3 A); v) apical margin of sternum 2 truncate, without medial protrusion (Fig. 3 E); vi) yellow preoccipital band reaching mandibular base. The new species is probably closely related to Pseudoanthidium eximium (Giraud, 1863), another species of the subgenus Exanthidium occurring in Azerbaijan, but the latter has a hooked lateral protrusion of tergum 6, rather straight posterior margin of scutellum in dorsal view, and a remarkably paler and less rich yellow pattern of the body (figs 6, 7 in Kasparek 2021). Besides this, P. astafurovae is distinct from P. eximium by a slenderer penis valve (especially its apical part) with much shorter hairs (Fig. 3 F, G vs fig. 3 G – I in Kasparek 2021) and distinctly pointed (not rather rounded) apical margins of sternum 7 (Fig. 3 E), as well as a distinctly pointed apical margin of sternum 8 (Fig. 3 C).	en	Fateryga, Alexander V., Maharramov, Mahir M., Proshchalykin, Maxim Yu.
