REMARKS. The description of M. semicircularis by van der Zanden (1996) perfectly fits the characters of the specimens listed in the above material; however, the type series includes several taxa and the male holotype does not belong to this species but belongs to

M. apicalis (C.J. Praz, in litt.).
