Remarks.
Both sexes of
M. palmeri
are separated from those of the first two species by having the shorter postspiracular setae on III and V–VI and more setae on tergites I–II. Additionally, both sexes have fewer setae in each sternite II aster and more setae on sternite III, the gula, and the metasternal plate than
M. masoni
, and more setae on sternite VII than
M. chesseri
. The male of
M. palmeri
is further recognized by its distinctive genital sac sclerite. The lack of extreme female tergal development, both sexes with shorter postspiracular setae on III and V–VI, and the male with the unique genital sac sclerite distinguish
M. palmeri
from all previously known species of this genus.

Etymology.
This species is named for Robert Palmer (CSIRO, Australian National Wildlife Collection) in recognition of his assistance in collecting lice from a wide variety of birds.
