title: Two pharyngodonid nematodes, Alaeuris mexicana n. sp. and Ozolaimus ctenosauri, from the iguanid lizard Ctenosaura pectinata from Nayarit, Mexico.
abstract: Two species of nematodes, Alaeuris mexicana n. sp. and Ozolaimus ctenosauri Caballero, 1938, were found in the iguanid lizard Ctenosaura pectinata (Wiegmann) from Aguamilpa, Nayarit, central Mexico (Pacific region). The new species, A. mexicana, differs from all congeners mainly in the length of the spicule (0.228-0.233 mm) and in the shape and size of the tail and caudal alae. Ozolaimus ctenosauri (syn. Ozolaimus prolixa Caballero et Cerecero, 1943) is considered a valid species parasitic in Ctenosaura spp. Scanning electron microscopic studies of both species revealed substantial differences in the structure of the mouth, which were used for the separation of the closely related genera Ozolaimus and Alaeuris.
