Rem.:

Nomen nudum in Epstein, 1949, described by Brodsky (1950).
For Brodsky (1967, p.301) this species differs from the closely similar M. brevicauda Giesbrecht in the 4-segmented P5 of the female, in the much smaller difference in the length of rhe right and left legs of P5 male.
For Vaupel-Klein (1970, p.35) the structure of P5 of the males of the species M. pacifica, gurjanovae and probably also M. asymmetrica is very similar and might be an indication of a closer relationship between these three species.
The geographic distribution of this form is surprising.
