Yet, only 10 species in the genus have had their life cycleinvestigated. Most species of Clytia are also poorly described, and detailed life cycle and morphological studies are needed for accurate species-level identifications. Here, we investigated the life cycle of Clytia elsaeoswal-dae Stechow, 1914, a species described for the tropical western Atlantic and subsequently considered conspecific to the nearly-cosmopolitan species Clytia gracilis (Sars, 1850) and Clytia hemisphaerica, originally described for the temperate North Atlantic. Based on observationsof mature medusae and multiple colonies from southeastern Brazil and the U. S. Virgin Islands (type locality), our results show that C. elsaeoswaldae is morphologically distinct from C. gracilis and C. hemisphaerica. The morphological results are corroborated by a multigene phylogenetic analysis of the genus Clytia, which shows that C. gracilis-like species form a polyphyletic group of several species. These results suggest that the nearly-cosmopolitan distribution attributed to some species of Clytia may be due to the non-recognition of morphologically similar species with more restricted ranges.

The following species are re-described: T. cuisinieri Carl, 1917, T. carli Attems, 1938, and T. foliaceus (Demange, 1961), new status (elevated from subspecies status under T. cuisinieri).

(the type species) and Taiwaneuma ramuligerum sp. nov. The family Niponiosomatidae is new to the fauna of Taiwan. The distributions of both new species are mapped.

查看更多>>摘要:A new species of the genus Charinus-C. vulgaris-is described from Porto Velho, Rondonia. This is the first record of the family Charinidae from the Brazilian Amazonia and of a synanthropic species in South America. Additionally, two new records of thegenus for Brazil are made and a key to the Brazilian species of the genus is given.
