摘要

Parapharyngiella Willems, Artois, Vermin, Backeljau & Schockaert, 2005, Parapharyngiella caribbaea n. sp.，描述自古巴的一新种。它不同于Parapharyngiella involucrum Willems, Artois, Vermin, Backeljau & Schockaert, 2005(该属中唯一的其他物种)，咽的位置要靠后得多，这表明咽的位置靠前不是该属的诊断特征。它的不同之处在于它的硬化性交配器官有一个比被膜长得多的突起。对已知的两个种群(桑给巴尔和西班牙)的形态重新评估表明，这些种群在许多细节上存在差异，表明它们属于两个不同的物种。因此，来自西班牙的种群被认为是一个单独的物种:Parapharyngiella steenkistei n. sp.此外，Proxenetes mackfirae Karling, 1978被转移到Parapharyngiella属。http://zoobank.org/urn:lsid:zoobank.org:pub:A78F4971-7193-461B-B161-99D2DB9D531A

Parapharyngiella caribbaea n. sp., a new species of Trigonostomidae (Rhabdocoela; Platyhelminthes) from Cuba, with a taxonomical reassessment of the genus

A new species of Parapharyngiella Willems, Artois, Vermin, Backeljau & Schockaert, 2005, Parapharyngiella caribbaea n. sp., is described from Cuba. It differs from Parapharyngiella involucrum Willems, Artois, Vermin, Backeljau & Schockaert, 2005, the only other species in this genus, by a much more posterior position of the pharynx, indicating that the anterior position of the pharynx is not a diagnostic character for the genus. It also differs in the sclerotized copulatory organ having a protuberance that is longer than the mantle. A morphological reassessment of the two known populations of P. involucrum (Zanzibar and Spain) reveals that these populations differ in many details, indicating that they belong to two different species. The population from Spain, therefore, is considered a separate species: Parapharyngiella steenkistei n. sp. Moreover, Proxenetes mackfirae Karling, 1978 is transferred to the genus Parapharyngiella. http://zoobank.org/urn:lsid:zoobank.org:pub:A78F4971-7193-461B-B161-99D2DB9D531A

期刊介绍： Tropical Zoology is an international zoological journal publishing original papers in the field of systematics, biogeography, phylogeny, ecology and conservation of all terrestrial and aquatic animal Phyla from tropical and subtropical areas. Only papers with new information, high quality and broad interest are considered. Single species description and checklists are not normally accepted. Review papers are welcome. The journal is owned by the Istituto di Ricerca sugli Ecosistemi Terrestri of the Consiglio Nazionale delle Ricerche, Florence, Italy (CNR-IRET) who performs research into the structure and functioning of aquatic and terrestrial ecosystems, focusing in particular on anthropogenic pressure and global change. The knowledge amassed forms the scientific basis for identifying the most appropriate protective and corrective interventions, and provides support for the bodies entrusted with formulating policies for environmental protection and recovery.
