Remarks

Warncke (1967) commented that he had a male specimen from La Marsa in Tunisia which matched Saunders’ type, but that he was not sufficiently confident that this species was synonymous with A. microthorax . Confusingly, he then only listed A. microthorax but not A. nigrocyanea in his North Africa revision ( Warncke 1974). Gusenleitner & Schwarz (2002) maintained this position, citing a lack of material. Examination of type material supports their conspecificity ( Figs 14A–D View Fig , 15A–D View Fig ). Andrena microthorax is unusual among the small former species of Carandrena in having the body almost entirely dark and without clear metallic green reflections, a trait it shares with A. nigrocyanea . Both species were described from Biskra, further supporting their conspecificity; the latter taxon is therefore formally synonymised here.

Distribution

Spain, Morocco *, Algeria, Tunisia ( Gusenleitner & Schwarz 2002).
