Abstract

Abstract: Two species of pinworms, Trypanoxyuris atelis and Trypanoxyuris atelophora were collected from the black-handed spider monkey ( Ateles geoffroyi ) in several localities across southeastern Mexico, representing the first record for both species in Mexican primates. Identification of pinworm species was based on morphological and molecular data. These pinworms are distinguished from other congeners, and from each other, by the buccal structure, the lateral alae, and the morphology of the oesophagus. Phylogenetic analyses based on sequences of the mitochondrial cytochrome c oxidase subunit 1 gene placed T. atelis as the sister species of Trypanoxyuris minutus, a parasite of the howler monkey Alouatta palliata, and T. atelophora as the sister species of T. microon, a parasite of the night monkey, Aotus azarae . These relationships were supported with high posterior probability values by Bayesian inference. Comparisons of additional pinworm taxa from Neotropical primates are needed to assess oxyurid diversity, and to better understand the evolutionary relationships among these nematodes and their primate hosts. Graphical abstract: Highlights: Record of Trypanoxyuris atelis and Trypanoxyuris atelophora in spider monkeys in Mexico. Mixed infections with these two pinworms were common. Buccal structure, lateral alae, and the oesophagus are the main diagnostic traits. Both species represent independent genetic lineages in phylogenetic analyses. Divergence suggests the potential existence of a cryptic species within T. atelis .
