Figs 50–51 , 56 , 58

Diagnosis

Differs from all other members of the tribe Leucogeorgiini by having an almost completely free mesomere separated by a deep incision from the mesomeral lamella. These two structures are connected only in the basal third in mesal view. Like some members of the genus Leucogeorgia , this genus is characterized by modified mouthparts.

Etymology

This new genus is named after the type locality of its type species, Martvili village. The name is a feminine noun.

Type species

Martvilia parva gen. et sp. nov., by present designation and monotypy.
