چکیده
Thubunaea ctenosauri sp. n. is described from the large intestine of the iguanid lizard Ctenosaura pectinata from Aguamilpa, Mexican State of Nayarit. It is characterized mainly by the position of the vulva, number and distribution of caudal papillae, length of spicules (0.066 mm), and size of eggs (0.054-0.060 X 0.039-0.042 mm). Other recorded species of parasitic nematodes are Skrjabinodon scelopori from Phyllodactylus lanei; Parapharyngodon alvarengai from P. lanei, Anolis nebulosus, and Sceloporus nelsoni; and Atractis scelopori from C. pectinata and Sceloporus sp. The findings represent new host records, and P. alvarengai is reported from Mexico for the first time.
