Mesocestoides sp.

Specimens deposited.

CNHE 9464, 9465.

Other hosts.

Sceloporus jarrovi Cope in Chihuahua, Morelos and San Luis Potosí ( Goldberg et al. 1996); S. grammicus Wiegmann in Mexico City ( Goldberg et al. 2003); S. torquatus Wiegmann in Querétaro ( Goldberg et al. 2003).

Remarks.

Four species of Mesocestoides are distributed in Mexico in carnivorous mammals: M. bassarisci MacCallum, 1921 in Bassariscus astutus Lichtenstein ( Procyonidae ) and M. lineatus (Goeze, 1782) in Mephitis macroura Lichtenstein ( Mephitidae ), both from Guerrero; M. variabilis Mueller, 1928 and M. vogae Etges, 1991 in Canis lupus familiaris Linnaeus ( Canidae ) from Mexico City ( Paredes-León et al. 2008). Unfortunately, the specimens found in S. pyrocephalus could not be identified to species level because they were at the tetratiridium larval stage. Molecular analyses are needed to determinate the species identity of the larvae found in reptilian hosts, which serve as intermediate hosts ( Santoro et al. 2012).
