Enderleinellidae
^a Except for Hoplopleura, Neohaematopinus and Polyplax, all known species in the remaining genera exclusively parasitise sciurid rodents. ^b Three species of squirrel-associated lice, Enderleinellus longiceps, Hoplopleura sciuricola and Neohaematopinus sciuri, have accompanied their host, the eastern grey squirrel, Sciurus carolinensis Gmelin, from North America to some other parts of the world as intentional or accidental squirrel introductions [Thompson 1935; Davis 1951 (louse misidentified as Neohaematopinus sciurinus), Durden & Musser 1994]. ^c Neohaematopinus callosciuri has accompanied its intentionally introduced host, Callosciurus erythraeus (Pallas squirrel), from Taiwan to Japan (Shinozaki et al. 2003, 2004).
