Seven gynandromorphic specimens [Bischof, Ulrich, 1929; Tums, 1970]), but most of of Megachile picicornis and M. deceptoria collected in them were mosaic and frontal gynandromorphs that the Crimea are described. All specimens of both spe- belonged to the genus Megachile Latreille, 1802 [Mitch- cies have similar morphology, i.e. the male-like head ell, 1929; Wcislo et al., 2004]. (except for the 12-segmented antennae) and legs as More than one hundred years ago, Cockerell de- well as the female-like metasoma that totally lacks scribed a female of the new species, Megachile detersa scopa.
