Type material. Holotype male ( USNM), ex G. r u f i g u l a, VENEZUELA: Edo. Bolivar, 60 km E Sta. Elena, Jan. 1987, R.C. Dalgleish. Paratypes: ( USNM) 6 females, 4 males, same data as holotype; ( INHS) 2 females, 2 males, same data as holotype.

Remarks. The dimensions of M. milleri are similar to those of the next species, both being distinctly smaller than those of M. mcleannani . The specific points for separating these two smaller species will be discussed under the remarks for the following species.

Etymology. This species is named for Matthew Miller, University of Alaska Museum, Fairbanks, in recognition of his assistance in collecting the lice used in this study and for his work on birds in Panama.
