Doubts expressed on the specific separation of M. mongolica (see Cobben, 1985: 260) are not supported by a re-examination of the holotype and studies of abundant fresh material from Mongolia. This species is clearly separated from M. jakowleffi sensu Cobben and other named taxa.
The record from Inner Mongolia (Li et al., 2008) probably refers to this species (Vinokurov et al., 2018).
