Heterodoxus spiniger (Enderlein, 1909)

Menopon spiniger Enderlein, 1909: 80, pl. 8, figs 4–5.

Coahuila: Canis lupus familiaris, no date (Lozoya-Saldaña et al. 1986); Capra aegagrus hircus, Buenavista (Lozoya-Saldaña et al. 1986).

Distrito Federal: Canis lupus familiaris, Reserva Ecológica del Pedregal de San Ángel (Pacheco-Coronel 2010). Tabasco: Canis lupus familiaris, Cárdenas, Centla, Villahermosa, May–June 2015 (Torres-Chable et al. 2017). Note: The record from the goat (Capra aegagrus hircus) is most likely the result of a contamination because H. spiniger is a regular and natural parasite of canids and marsupials only (see Price et al. 2003).
