Grichanov (2002) assigned M. petrophiloides as a junior synonym of M. petrophila . However, this is not accepted here and both species can be readily distinguished by a number of characters (e.g., shining vs. pollinose clypeus, colour of propleural bristles and hairs on fore coxae, and some details of the male hypopygium), as Parent (1938, figs 557–559) has already indicated. Additionally, M. petrophiloides has only one strong mesonotal presutural bristle, narrow and long hypopygium (epandrium nearly as long as abdominal segment 4), the face with shining median spot; surstyli are about 1.5 times shorter than epandrium but considerably longer than epandrium is broad ( Figs. 13, 14 ). In M. petrophila there are two dorsocentral presutural mesonotal bristles, the hypopygium is broader, surstyli are short, more than two times as short as the epandrium and shorter than the epandrium is broad ( Figs. 15, 16 ). Careful examination of the types of both these specimens is required to confirm the proposed validity of these species.
