Resumen:
Two new species of Trypanoxyuris are described from the intestine of
free-ranging howler monkeys in Mexico, Trypanoxyuris multilabiatus n.
sp. from the mantled howler Alouatta palliate, and Trypanoxyuris pigrae
n. sp. from the black howler Alouatta pigra. An integrative taxonomic
approach is followed, where conspicuous morphological traits and
phylogenetic trees based on DNA sequences are used to test the validity
of the two new species. The mitochondrial cytochrome oxidase subunit 1
gene, and the nuclear ribosomal 185 and 28S rRNA genes were used for
evolutionary analyses, with the concatenated dataset of all three genes
used for maximum likelihood and Bayesian phylogenetic analyses. The two
new species of pinworms from howler monkeys were morphologically
distinct and formed reciprocally monophyletic lineages in molecular
phylogenetic trees. The three species from howler monkeys, T.
multilabiatus n. sp., T. pigrae n. sp., and Trypanoxyuris minutus,
formed a monophyletic group with high bootstrap and posterior
probability support values. Phylogenetic patterns inferred from sequence
data support the hypothesis of a close evolutionary association between
these primate hosts and their pinworm parasites. The results suggest
that the diversity of pinworm parasites from Neotropical primates might
be underestimated. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
