One is a new species that has been mis-identified for the last 37 years and one is allocated to a different genus from that to which it was previously assigned. Pista corrientis Mcintosh, 1885 was described from Argentina and has been reported from several localities along the Brazilian coast. Examination of the holotype of P. corrientis revealed that the Brazilian specimens belong to a separate species, herein describedas P. nonatoi sp. nov., and a redescription of the holotype of P. corrientis is provided. Pista sombreriana (Mcintosh, 1885) was considered indeterminable due to the poor condition of the holotype. Our examination of the holotype showed that although itis poorly preserved most taxonomic characters are visible. The morphology of the lobes on anterior segments, especially those of segments 3-4, is closer to Lanicides than to Pista but considering that Lanicides is also poorly defined we redescribe P. sombreriana under its original designation. Finally, Eupolymnia turgidula (Ehlers, 1887) has been considered as a junior synonym of E. crassicornis (Schmarda, 1861) but a recent study resurrected it as a valid species of Terebella, which was the original generic designation. According to our examination of the holotype, E. turgidula does belong to Eupolymnia, but it is uncertain as to whether it is a valid species or a synonym of either E. crassicornis or E. magnifica (Webster, 1884).

The genus was established by Verrill for three eastern Pacific species, another was described by Breedy and Guzman in 2005, and the geographic distribution was extended with the discovery of a western Atlantic species described by Castro in 1990. Heterogorgia is characterised by colonies composed of a number of stout stems that branch laterally and irregularly and arise from a conspicuous spreading holdfast. Coenen-chymal sclerites are mostly colourless spindles; anthocodiae have strong spindles arranged in collaret and points; and the calyces are prominently armed withwhorls of strongly projecting thorns. To define Heterogorgia we examined original type material of all eastern Pacific and western Atlantic species described until now and reference specimens from recent expeditions along the eastern Pacific. Morphological characters are analysed and illustrated using scanning electron micrographs. Lectotypes are designated for H. tortuosa and H. verrucosa to establish their taxonomic status. We conclude that Heterogorgia is comprised of five valid species at present: Heterogorgia hickmani and H. verrucosa for the Galapagos Islands and Ecuador mainland; H papillosa for Mexico; H. tortuosa and H verrucosa for Costa Rica and Panama; and H. uatumani for Brazil and Bahamas. The genera Astromuricea, Bebryce, Echinogorgia and Psammogorgia are proposed for the western Pacific species that were historically misplaced in Heterogorgia. We recommend that regional biodiversity estimates and biogeography analyses consider the erroneous status of the species that are still listed as Heterogorgia within the data sets.

A new subgenus, Zercon (Zercorientalia) subgen. nov., is established for these species, on the basis of a unique combination of podonotal chaetotaxy and pore positions. Zercon (Zercorientalia) sinensis Petrova & Taskaeva, 1968 is transferred from Zercon (Zercon) Koch, 1836 to the new subgenus. The taxonomic relevance of podonotal chaetotaxy is discussed.

Hosts, geographic distribution and relevant references are provided for each species. Three erroneous records published recently, two in a book on New Zealand biodiversity and one in a seabird tick review are corrected.
查看更多>>摘要：The names Bergia Duchassaing & Michelotti, 1860, and Bergiidae Verrill, 1869, are respectively, senior subjective synonyms of Parazoanthus Haddon & Shackleton, 1891, and Parazoanthidae Delage & Herouard, 1901. The junior synonyms Parazoanthus and Parazoanthidae are in current and widespread use. In the interest of nomenclatural stability, we enact Articles 23.9.1 and 23.9.2 to reverse precedence of these names, thereby making Parazoanthus and Parazoanthidae nomi-na protecta, and Bergia and Bergiidaenomina oblita.
