| glypthelmins poncedeleoni n. sp. (trematoda: macroderoididae) of amphibians from the neotropical region of méxico. | a new species of glypthelmins (trematoda: macroderoididae) is described from the intestine of bufo marinus and leptodactylus melanonotus from several localities of the neotropical region of mexico. glypthelmins poncedeleoni n. sp. can be differentiated from other species of the genus by having extracecally distributed vitellaria, ovary always larger than testes, and vitelline follicles grouped in 7 post-testicular, nonoverlapping, rosette-like clusters and 5 pretesticular overlapping clusters. | 2001 | 11426736 |
| helminth infracommunity structure of leptodactylus melanonotus (anura) in tres palos, guerrero, and other records for this host species in mexico. | the amphibian genus leptodactylus includes around 50 species, of which only 2 are distributed in mexico; the helminth fauna of these 2 species is poorly known. as part of a research program on amphibian parasites in mexico from 1997 to 2005, 281 sabinal frogs leptodactylus melanonotus from 42 localities in 11 mexican states were examined from a helminthological perspective. a total of 20 taxa of helminths-7 digeneans (5 adults, 2 larvae) and 13 nematodes (8 adults, 5 larvae)-was found to infect ... | 2013 | 23157315 |
