Abstract

Faunistic survey of Tanzania and Uganda resulted in the finding of eight species belonging to the genus Echiniscus C.A.S. Schultze, 1840, three of which are new to science. Echiniscus belloporus n. sp. has no trunk cirri and dorsal plates densely covered with pores (sculpture of the spinulosus type); it lacks a spine I and the dentate collar IV, a combination of traits so far unseen in Echiniscus. Echiniscus ornamentatus n. sp. possesses regularly distributed pores on its dorsal plates, scapular and caudal plates with contrasting faceting, and anterior portions of the paired plates distinctly darker than their posterior parts. Echiniscus tristis n. sp. is also a new member of the spinulosus group, but differs from all other species of this complex by having small pores, a trunk appendage combination C-Dd-E, and large spurs on its internal claws. Three other species: Echiniscus baius, Echiniscus dariae and Echiniscus manuelae, are recorded as new additions to the African fauna. Two last species: Echiniscus africanus and Echiniscus cirinoi, are scarcely reported elements of the Afrotropical fauna. Scanning electron microscopy microphotographs supplementing the description of E. dariae, and amendments to the outdated description of E. manuelae are also provided. http://zoobank.org/urn:lsid:zoobank.org:act:B8494205-58D5-4E54-B54E-2C40976892E1http://zoobank.org/urn:lsid:zoobank.org:act:F439D375-F44F-4C3A-997F-EDC0D0A45F88http://zoobank.org/urn:lsid:zoobank.org:act:B602FA08-3E17-4149-A1FE-22829E13DFFD

1840年，在坦桑尼亚和乌干达的调查中发现了8种棘轮属(Echiniscus)，其中3种为新种。棘棘棘轮(Echiniscus belloporus n. sp.)没有树干卷毛，背板密被气孔覆盖(棘棘类型的雕刻);它没有1号脊椎和4号齿状颈圈，这是迄今为止在棘猿中从未见过的特征组合。针鼹(Echiniscus装饰物)的背板、肩胛骨和尾板上的孔分布规律，面形对比明显，成对板的前部明显比后部深。Echiniscus tristis n. sp.也是棘纲的新成员，但与该复合体的所有其他物种不同的是，它有小毛孔，躯干附属物组合C-Dd-E，其内爪上有大刺。另外三个物种:绵锥菊、达瑞绵锥菊和马努绵锥菊被记录为非洲动物群的新成员。最后两种:非洲紫锥花和cirinoi紫锥花，很少被报道为非洲热带动物群的组成部分。还提供了扫描电子显微镜显微照片，补充了dariae的描述，并修改了过时的E. manuelae描述。http://zoobank.org/urn:lsid:zoobank.org:act:B8494205-58D5-4E54-B54E-2C40976892E1http://zoobank.org/urn:lsid:zoobank.org:act:F439D375-F44F-4C3A-997F-EDC0D0A45F88http://zoobank.org/urn:lsid:zoobank.org:act:B602FA08-3E17-4149-A1FE-22829E13DFFD

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.
