| phylogenetic affinities of auriculostoma (digenea: allocreadiidae), with descriptions of two new species from peru. | abstract abstract: two new allocreadiid trematodes are described from the intestine of characid fishes from rio itaya, a tributary of the amazon river near iquitos, peru. auriculostoma foliaceum n. sp. is described from bryconops cf. caudomaculatus (günther, 1864) backup, 2003, and auriculostoma diagonale n. sp. from stethaprion cf. erythrops cope, 1870. auriculostoma foliaceum n. sp. differs from its congeners by having a foliated lateral margin and lacking vitelline follicles in the forebody. ... | 2011 | 21506841 |
| systematic position and relationships of paracreptotrematina limi, based on partial sequences of 28s rrna and cytochrome c oxidase subunit 1 genes. | paracreptotrematina limi amin and myer, 1982 (trematoda), an intestinal fluke specific to the mudminnow, umbra limi, is conventionally classified within the papillose allocreadiidae. its unusual morphology (lack of identifiable vitellaria, large fully embryonated terminal eggs), assumptions of homology of its 2 atypical muscular oral 'papillae' (lobes) with those of the bunoderinae, and its unknown life cycle make this classification tenuous. previous phylogenetic analyses of the papillose alloc ... | 2006 | 16729708 |
