Item A new species of the troglobitic genus Spelaeogammarus da Silva Brum, 1975 (Amphipoda: Artesiidae) from a cave in the Brazilian semi-arid region, with new records of its congener, Spelaeogammarus spinilacertus Koenemann and Holsinger, 2000(2022-06-17) Bueno, Alessandra Angélica de Pádua; Bichuette, Maria Elina; Zepon, Tamires; Penoni, Ludmila RochaWe propose a new species of the troglobitic genus Spelaeogammarus da Silva Brum, 1975, with data on its distribution, ecology, aspects of behavior, and conservation status. Spelaeogammarusginae sp. nov. occurs in a single cave in the Serra do Ramalho karst area, of the northeastern Brazilian semi-arid region. We also provide new data on the distribution and conservation status of its congener, Spelaeogammarus spinilacertus Koenemann and Holsinger, 2000 that occurs in the upper phreatic aquifer inside caves from Chapada Diamantina domain. Both species occur in caves in the state of Bahia, northeastern Brazil.- Spelaeogammarus uai (Bogidielloidea: Artesiidae): a new troglobitic amphipod from Brazil(Magnolia Press, 2017) BASTOS-PEREIRA, RAFAELA; FERREIRA, RODRIGO L.A new species was recently found in a cave from Southeastern Brazil, in the state of Minas Gerais, which is here described. Considering all the species of the genus, Spelaeogammarus uai sp. nov. is very similar to S. santanensis and S. sanctus, although the new species differs mainly in relation to the number of plumose setae in the apical margin of maxilliped inner plate, number of setae in the anterior margin of gnathopod 1 basis and number of setae in the posterior margin of gnatho-pod 2 basis. Furthermore, the ratio “length/width” of several articles of the new species is higher than in other species. An identification key of the Spelaeogammarus genus is provided, as well as a complemented multivariate statistical approach of the morphometry of the genus based on a previous work of the genus.
