Resumen:
A new genus and species of nematode, Tziminema unachi n. gen., n. sp. is
described from the caecum and colon of Baird's tapir Tapirus bairdii
(Gill, 1865), found dead in the Reserva de la Biosfera El Triunfo,
Chiapas State, in the Neotropical realm of Mexico. Tziminema n. gen.
differs from the other nine genera included in the Strongylinae by two
main characteristics: having 7-9 posteriorly directed tooth-like
structures at the anterior end of the buccal capsule, and the external
surface of the buccal capsule being heavily striated. Phylogenetic
analyses of the DNA sequences of the mitochondrial cytochrome c oxidase
and nuclear DNA, including a partial sequence of the internal
transcribed spacer 1, 5.8S and a partial sequence of the internal
transcribed spacer 2 of the new taxon, confirmed its inclusion in
Strongylinae and its rank as a new genus.
