FALCON-ORDAZ, Jorge et al. Angiostoma lamotheargumedoi n. sp. (Nematoda: Angiostomatidae) from the intestine of Pseudoeurycea mixteca (Caudata: Plethodontidae) in central Mexico. Rev. Mex. Biodiv. [online]. 2008, vol.79, suppl., pp.107-112. ISSN 2007-8706.

A new species of Angiostoma (Angiostomatidae) is described from the intestine of the plethodontid salamander, Pseudoeurycea mixteca from Puebla State, in central Mexico. The new species closely resembles Angiostoma limancis, Angiostoma kimmeriensis, Angiostoma spiridonovi, Angiostoma stammeri, and Angiostoma carettae, because they all possess 8 pairs of pedunculate papillae in the caudal region; however, the new species can be distinguished by the unique arrangement of papillae, with 1 pre-cloacal pair, and 7 post-cloacal pairs. Among the 12 congeneric species of Angiostoma described so far, 2 have been described as parasites of salamanders, Angiostoma plethodontis from Plethodon cinereus and Plethodon richmondi in Virginia, USA, and Angiostoma onychodactyla from Onychodactylus japonicus in Japan. Angiostoma lamotheargumedoi n. sp. is readily distinguished from these 2 species by the presence of lateral alae and by the number of pre-cloacal papillae.
