Etymology
Etymology. Named after Mrs. and Mr. Tanner, who initiated the establishment of the Mazumbai Forest Reserve. Diagnostic characters. The male groups with M. diseta new species and M. elegans new species in having a forked gonostylus and gonocoxite with long lobes. It can be separated from both species by having moderately long, straight lobes of tergite 9.
