Resumen:
Two new species of Parapharyngodon collected from the intestine of the
Mexican boulder spiny lizard Sceloporus pyrocephalus are described. This
study increases to 49 the number of valid species assigned to
Parapharyngodon worldwide, 11 of them distributed in Mexico. Males of
the two new species share the presence of four pairs of caudal papillae,
an anterior echinate cloacal lip and the presence of lateral alae;
however, both differ from each other in lateral alae extension and
echinate cloacal anterior lip morphology. Females of both species have a
prebulbar uterus and eggs shell punctuate with pores, characteristics
shared with few other species of Parapharyngodon. Both new species
differ from other congeneric species in the papillar arrangement, the
anterior cloacal lip morphology, the lateral alae extension and total
length/spicule ratio. A taxonomic key for the species of Parapharyngodon
distributed in Mexico is provided.
