A new species of Cheiriphotis (Amphipoda, Corophiidae) from the southwestern Atlantic Ocean

A new species, Cheiriphotis petronioi sp. nov., is described from the Brazilian coast. This species is recognizable amongst its congeners by the carpus of adult male gnathopod 2 not fused with propodus and the palm acute and uropod 1 of adult males without a group of apical setae between rami. Specimens studied herein were collected between 23º and 34ºS (Brazil - São Paulo and Rio Grande do Sul) from 16 to 38 m depth. An updated key to all species of the genus is provided

First record of the genus Ruffojassa Vader & Myers, 1996 (Amphipoda, Corophiidea) from Brazilian waters, with description of a new species

A new species, Ruffojassa petronioi sp. nov., is described from southern Brazilian coast. The new species was collected at 56 m depth at the coordinates 21º42'S / 40º15'W with a mini biological trawl aboard of R.V. Prof.W.Besnard. In this paper we recorded the genus for the first time from Brazilian waters

The World Amphipoda Database: history and progress

We provide an overview of the World Amphipoda Database (WAD), a global species database that is part of the World Register of Marine Species (WoRMS). Launched in 2013, the database contains entries for over 10,500 accepted species names. Edited currently by 31 amphipod taxonomists, following WoRMS priorities, the WAD has at least one editor per major group. All accepted species are checked by the editors, as is the authorship available for all of the names. The higher classification is documented for every species and a type species is recorded for every genus name. This constitutes five of the 13 priorities for completion, set by WoRMS. In 2015, five LifeWatch grants were allocated for WAD activities. These included a general training workshop in 2016, together with data input for the superfamily Lysianassoidea and for a number of non-marine groups. Philanthropy grants in 2019 and 2021 covered more important gaps across the whole group. Further work remains to complete the linking of unaccepted names, original descriptions, and environmental information. Once these tasks are completed, the database will be considered complete for 8 of the 13 priorities, and efforts will continue to input new taxa annually and focus on the remaining priorities, particularly the input of type localities. We give an overview of the current status of the order Amphipoda, providing counts of the number of genera and species within each family belonging to the six suborders currently recognized

A new species of Pseudharpinia (Amphipoda: Haustorioidea: Phoxocephalidae) from Southeastern Brazilian continental shelf

Abstract A new species of the amphipod family Phoxocephalidae Sars, 1895, Pseudharpinia tupinamba sp. nov., is described from southeastern Brazilian continental shelf. The new species is closely related to the type-species of the genus, P. dentata Schellenberg, 1931 described from Magellan Province, and was misidentified as the latter species by some authors in the past. Pseudharpinia tupinamba sp. nov. differs from P. dentata by the number of articles in the accessory flagellum of antenna 1, ratio of length and width of the propodus of pereopod 6, size of the posteroventral lobe of the basis of pereopod 7, presence of slender setae in posterior margin of epimeral plate 3, presence of a corona of cuticular spines in dorsodistal margin of peduncle of uropod 2, ratio of length of the inner ramus and the first article of outer ramus of uropod 3, ratio of length and width of the telson, and presence of slender setae on the lateral margins of telson. The new described species is the unique of this genus known from the Brazilian continental shelf

Species of Excorallana (Isopoda, Corallanidae) from northern and northeastern Brazil, with description of a new species, Excorallana lemoscastroi sp. nov.

Abstract Several Brazilian specimens of the genus Excorallana Stebbing, 1904, were revised based on material deposited in the carcinological collection of the Museu de Oceanografia Prof. Petrônio Alves Coelho, Universidade Federal de Pernambuco, Recife, Brazil. The material examined was collected during oceanographic expeditions off northern and northeastern Brazil between 1965 and 2000. Seven species were identified: Excorallana bicornis Lemos de Castro & Lima, 1971; Excorallana costata Lemos de Castro, 1960; Excorallana oculata (Hansen, 1890); Excorallana richardsoni Lemos de Castro, 1960; Excorallana subtilis (Hansen, 1890); Excorallana warmingii (Hansen, 1890); and a putative new species, Excorallana lemoscastroi sp. nov. The new species was found in Paraíba and Pernambuco and shares characters with Excorallana antillensis (Hansen, 1890), in having the head and pereon unornamented; the pleon with tubercles; and the pleotelson triangular, with a lateral incision and with four tubercles on the anterior margin. However, the two species differ in the head size, length of the antenna, shape of the frontal lamina, and number and arrangement of tubercles on the pleon

A new species of Cirolana Leach, 1818 (Isopoda, Cymothoidea, Cirolanidae) from Brazilian coast

A new species of Cirolana is described from the Northeast Brazilian coast based on the material previously recorded as Cirolana palifrons and some other material misidentified as C. parva. The new species, C. lemoscastroi sp. nov., belongs to a group of species within the genus that have two dorsal longitudinal carinae on the pleotelson. A key to all Cirolana species recorded from Brazil is provided
