JIMENEZ, F. Agustín; ROSAS-VALDEZ, Rogelio  y  GARDNER, Scott L.. A new species of Metathelazia (Nematoda: Pneumospiruridae) from the lungs of a nine-banded armadillo in Central Mexico. Rev. Mex. Biodiv. [online]. 2013, vol.84, n.1, pp.87-93. ISSN 2007-8706.  https://doi.org/10.7550/rmb.29516.

Twenty-four worms were collected from the bronchioles in both lungs of a male nine-banded armadillo Dasypus novemcinctus Linnaeus, 1758 captured in Teacalco, Morelos, Mexico. The worms, herein named Metathelazia mexicana n. sp., show a constriction in the esophagus at the level of the nerve ring; males of the species have 7 pairs of papillae, fewer than the other species in the genus. Metathelazia capsulata is the most similar species to Metathelazia mexicana; however, the latter has much shorter spicules. This is the fourth species in the genus known to occur in the New World.

Palabras llave : Dasypus novemcinctus; Morelos; Mexico; nine-banded armadillo; Metathelazia mexicana; Metathelazia capsulata.
