Basal half of penis valves of moderate width, flanked by narrow, arched lamellae, apical half narrow ( Fig. 176 ). Sternum 8 columnar, narrowed at mid length ( Figs. 177–178 ). Diagnosis. Andrena dorchini is closely related to the Andrena doursana species group. Five species are currently recognised in this group, the females of which are almost impossible to tell apart: A. alchata Warncke (female unknown), A. derbentina Morawitz , A. doursana Dufour, A. mizorhina Warncke and A. mucronata Morawitz. Andrena dorchini differs from members the doursana group by the blacker cuticle colour (usually strongly bluishmetallic in the doursana group), brown flagellum (flagellomeres 3–11 orange anteriorly in the doursana group), more triangular arrangement of ocelli (almost linear in the doursana group), stronger, coarser and denser mesonotal punctation especially in the female, and weaker and finer, almost imperceptible tergal punctation. Males are further separated by the yellow marked clypeus and black paraocular areas (with yellow on paraocular areas in A. alchata , only apex of clypeus yellow marked in A. doursana and A. derbentina , clypeus entirely dark in mizorhina ) and the absence of a medioapical spine on the clypeus (clypeus with a clear spine in A. mucronata ).
