Resumen:
We examined the morphology of gnathostome larvae obtained in Temazcal and Sinaloa, Mexico, mainly using scanning electron microscopy. The mean body length was 4.67 mm. The head had 4 transverse rows of hooklets, and the mean number of each row was 40, 44, 47 and 50. The bodies were wholly covered with minute cuticular spines along their transverse striations. The mean number of striations varied from 227 to 275. The cervical papillae were situated between the 13th and 17th transverse striations and most specimens had them between the 14th and 15th transverse striations. An excretory pore was also located between the 24th and 28th transverse striations. We identified this Mexican gnathostome as Gnathostoma cf. binucleatum Almeyda-Artigas, 1991.
