Remarks.
Both
M. milleri
and
M. mayermae
share similar small dimensions, thereby differing from
M. mcleannani
. Features for recognizing
M. mayermae
include female with a shorter total length, male with fewer tergal setae on IV–VII and fewer sternal setae on IV–VIII, and both sexes with fewer marginal setae between the asters on sternite II.
Etymology.
This species is named for Peggy Guitton-Mayerma, University of Alaska Museum, Fairbanks, in recognition of her assistance in collecting the lice used in this study.
