Differential diagnosis
The females of this species are morphologically similar to those of M. nuaulu sp. nov., by having the antennae with 11 flagellomeres, the probasisternum strongly large with anterior margin strongly angulated, and the wings fully developed. However, M. navatu sp. nov. has the head at least 1.50 × as long as wide with the sides diverging posterad, in dorsal view, and the probasisternum with posterior margin straight, whereas the M. nuaulu has the head at most 1.40 × as long as wide with the sides parallel, in dorsal view, and the probasisternum with posterior margin curved.
Etymology
The epithet navatu is derived from the Navatu, a Fijian tribe that migrated and currently resides in Cakaudrove.
