A new species of Heteromyoxyuris (Nematoda: Oxyuridae), parasite of Dipodomysspp. (Rodentia: Heteromyidae) from Mexico
A new species of Heteromyoxyuris, parasitic on the caecum of Dipodomys merriami and Dipodomys ordii from the Mexican Plateau, is described and illustrated. This species differs from the other 3 species by the absence of lateral alae in both sexes and resembles males of Heteromyoxyuris deserti by the presence of a pair of caudal cuticular inflations. The distribution of the 4 species of Heteromyoxyuris coincides with the geographical distribution of the heteromyid rodent subfamilies Dipodomyinae and Perognathinae across the deserts and arid lands of USA and Mexico. A key to the species of Heteromyoxyuris is provided. Heteromyoxyuris garciaprietoi n. sp. is the fourth species described for the genus and the second described for Mexico.
