Descriptions of Acanthocephalus parallelcementglandatus (Echinorhynchidae) and Neoechinorhynchus (N.) pennahia (Neoechinorhynchidae) (Acanthocephala) from amphibians and fish in Central and Pacific coast of Vietnam, with notes on N. (N.) longnucleatus

Three species of acanthocephalans are described from fishes caught in the Pacific coast off eastern Vietnam and from amphibians in the midlands in 2016: (1) Acanthocephalus parallelcementglandatus Amin, Heckmann, Ha, 2014 (Echinorhynchidae), described from 1 male specimen is now fully described from males and females collected from 2 species of amphibians, the similar frog Hylarana attigua Inger, Orlov, Darevsky and the odorous frog Odorrana sp. Fei, Ye, Huang (Ranidae) in Huong Thuy, Hue City and Chu Yang Sin Park, central Vietnam, respectively, as well as from the needlefish Tylosurus sp. Cocco (Belonidae) in Binh Thuân in the Pacific South. The allotype female is designated. Neoechinorhynchus (N.) pennahia Amin, Ha, Ha, 2011 described from 1 female specimen is now fully described from males and females collected from the Toli shad (Chinese herring), Tenualosa toli (Valenciennes) (Clupeidae) in the Pacific north coast off Haiphong. The allotype male is designated. One specimen of Neoechinorhynchus (Neoechinorhynchus) longnucleatus Amin, Ha, Ha, 2011 is also reported from the common ponyfish, Leiognathus equulus (Forssskål) (Leiognathidae) in the Pacific south coast of Nha Trang and its ecology briefly discussed.
