Revision of Bursacetabulus (Diplostomidae: Diplostominae) with the proposal of Bursatintinnabulus n. gen., and description of Bursatintinnabus bassanus n. sp. and Bursacetabulus morus n. sp. from northern gannet, Morus bassanus (Aves), from the Texas gulf coast. Academic Article uri icon


  • During a study of digeneans of shorebirds from the Texas gulf coast, 2 undescribed species of diplostomes were found in northern gannet, Morus bassanus. Bursatintinnabulus n. gen. (Diplostomidae) is established with reassignment of Bursacetabulus macrobursus Dronen et al., 1999, as type species, and the second species in the proposed genus is described, Bursatintinnabulus bassanus n. sp. Generic diagnosis of Bursacetabulus Dronen et al., 1999, is emended to include a conical hindbody, an inconspicuous pouchlike or conspicuous well-developed tribocytic organ, and digitiform vitellaria distributed mainly in the hindbody with processes extending into the tribocytic organ and ventrolaterally in the hindbody to the level of the testes. Bursacetabulus morus n. sp. is described as the second species in that genus. In Diplostominae, Bursacetabulus and Bursatintinnabulus n. gen. are most similar to Tylodelphys Diesing 1850, but can be distinguished by having smooth testes and vitellaria that extend ventrolaterally into the hindbody to the level of the posterior testis; and the absence of a genital cone, an acetabulum, and a prepharynx. Bursatintinnabulus n. gen. is different from Bursacetabulus and all other genera of Diplostominae by a well-developed, bell-like skirt surrounding the bursa.
