Pseudoacanthocephalus nguyenthileae n. sp. (Palaeacnthocephala: Echinorhynchidae) was collected from 5 species of terrestrial amphibians: (1) the common Sunda toad Bufo melanostictus Schneider (Bufonidae); (2) Paa verucospinosa (Bourret); (3) Gunther's Amoy frog Rana guentheri Boulenger; (4) Taipei frog R. taipehensis Denburgh (Ranidae), and (5) the Burmese whipping frog Polypedates mutus (Smith) (Racophoridae); as well as from the Chinese cobra Naja atra Cantor (Reptilia: Elapidae) and house gecko Hemidactylus frenatus Dumeril and Bibron (Reptilia: Gekkonidae). Sphaerechinorhynchus maximesospinus n. sp. (Plagiorhynchidae: Sphaerechinorhynchinae) was isolated from a king cobra Ophiophagus hannah (cantor) (Reptilia: Elapidae). Cystacanths of Porrorchis houdemeri (Joyeux and Baer, 1935) Schmidt and Kuntz, 1967 (Plagiorhynchidae: Porrorchinae) obtained from the mesenteries of banded krait Bungarus fasciatus (Schneider) (Reptilia: Elapidae), a paratenic host, are reported for the first time. Keys to the species of Pseudoacanthocephalus and Sphaerechinorhynchus are included. Characteristic features distinguishing the new species from related taxa include: P. nguyenthileae has 15-19 (usually 16-18) proboscis hook rows, each with 5-6 hooks that progressively increase in length and size posteriorly. The largest, intermediate, and smallest proboscis hooks of S. maximesospinus are the middle, anterior, and posterior hooks, respectively; the proboscis and neck are enclosed in a membrane. Morphometric characteristics of P. nguyenthileae show host-related variability.</p>10aAcanthocephala10aAmphibians10aAnimals10aFemale10aHelminthiasis, Animal10aMale10aPrevalence10aReptiles10aVietnam1 aAmin, Omar, M1 aVan Ha, Ngyuen1 aHeckmann, Richard, A  uhttps://acanthocephala.myspecies.info/node/3401789nas a2200277   4500008004100000022001400041245013700055210006900192260001300261300000900274490000700283520097200290653001901262653001501281653001201296653002501308653001101333653001101344653002601355653000901381653001701390653002401407653001201431100001801443856005001461       2002                        eng d  a0165-575200aRevision of Neoechinorhynchus Stiles & Hassall, 1905 (Acanthocephala: Neoechinorhynchidae) with keys to 88 species in two subgenera.0 aRevision of Neoechinorhynchus Stiles Hassall 1905 Acanthocephala  c2002 Sep  a1-180 v533 a<p>Neoechinorhynchus Stiles &amp; Hassall, 1905 is revised based on both bibliographic studies and the examination of material. The evolution of the concept of the genus is discussed. The concept of Hebesoma Van Cleave, 1928 is also commented upon. The synonymy of the two genera is accepted, with Neoechinorhynchus having priority, and a new diagnosis for Neoechinorhynchus is provided. However, Hebesoma is recognised as a subgenus of Neoechinorhynchus, being differentiated from the nominal subgenus primarily on features of the egg. Of the 109 species studied, seven are transferred to other genera and 14 are considered invalid. Eleven species are assigned to the subgenus Hebesoma and 48 to the subgenus Neoechinorhynchus. Twenty-nine species were not assigned because of incomplete or absence of descriptions of adult females. Keys to assigned and non-assigned species are provided. Notes on the zoogeography of the 88 accepted species are also included.</p>
