Hypopygium ( Figs 1–5 ). Tergite IX with anal point 72–88 μm long and with 46–

49 setae, some of that situated in basal part of anal point; laterosternite IX with 12–

13 setae. Gonostylus in middle outer part prominent, 152–156 μm long, with megaseta 64 μm long and 1–2 setae nearest 80 μm long. Gonocoxite 356–368 μm

REMARKS. M. kamora belongs to the group of species bathyphila . Male imagines of M. kamora is close related to M. alpicola Brundin and M. bathphila

Kieffer but can be separated from these species by shape of gonostylus which in middle outer part prominent. Median volsella spine-like, slightly curved and situated on long pedestal. Near of median volsella in anterio-ventral part situated seta on small tubercle. Inferior volsella in distal part wide-roundish and just a little longer of superior volsella.
