( Figures 31A–D ) Remarks. The subgenus Cnemidandrena Hedicke, 1933 is taxonomically challenging, even in Europe. Alfken (1931) described a subspecies of A. nigriceps (Kirby, 1802) , a species that is widespread in temperate parts of the West Palaearctic. Examination of the type material of A. nigriceps ssp. pamirensis shows that it is conspecific with A. jagnobensis (illustrated in Astafurova et al . 2021 ); both taxa were described from Tajikistan . If the suspected type localities are correct, then the two taxa were described from within 100 km of each other. Alfken (1936: 827) even reports three females and two males of A. jagnobensis from the same place and day! Andrena jagnobensis can be separated from A. nigriceps due to the polished and shining clypeus, with clear shining interspaces between clypeal punctures ( Figure 31C ). The type specimen of A. nigriceps ssp. pamirensis simply represents an individual with darker than average pubescence relative to typical A. jagnobensis ( Figure 31D ). True A. nigriceps is unknown from Central Asia, and hence A. nigriceps ssp. pamirensis is synonymised syn. nov. with A. jagnobensis . More broadly, since Gusenleitner & Schwarz (2002) list A. jagnobensis as a junior synonym of A. nigriceps , the works of Osytshnjuk et al . (2005) and Astafurova et al . (2021) can be used to justify the species-status of A. jagnobensis . Material examined. TAJIKISTAN : Jagnob , Kol , 1892, 1♀ , leg.
