ABSTRACT: Three species and one subspecies of lice in the genus Myrsidea are described and illustrated from passerine hosts from the Galápagos Islands. New taxa are: Myrsidea darwini new species (type host Geospiza fuliginosa Gould, Emberizidae); Myrsidea nesomimi nesomimi new species and subspecies (type host Nesomimus macdonaldi Ridgway, Mimidae); and Myrsidea nesomimi borealis new subspecies (type host Nesomimus parvulus (Gould), Mimidae). Myrsidea ridulosa (Kellogg & Chapman) is recorded for the first time in the Galápagos Islands, from Dendroica petechia aureola (Gould) (Parulidae). Myrsidea nesomimi is the first species of Myrsidea described from members of the family Mimidae.
