Colpocephalum sp.

Colima: Puffinus auricularis, Clarion Island, 1897, R.C. McGregor (Kellogg & Mann 1912). Distrito Federal: Hylocharis leucotis, Pueblo de Santa Rosa, Suroeste de la Ciudad de Mexico, sobre los kilómetros 27–31 de la carretera que va al Desierto de los Leones, 1942 (CNIN-PHT0001). Note: Both records of Colpocephalum sp. listed above are most likely the result of contaminations or misidentifications of the lice because there is no species of Colpocephalum parasitising any species of Puffinus or hummingbirds (see Price et al. 2003).
