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 gnathopod 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.

Megagidiella azul, a new genus and species, is described from Gruta do Lago Azul, a cave in central-western Brazil. With a body length of more than 16 mm, this species is the largest bogidiellid recorded to date. In addition to its large size, the absence of a mandibular palp is a unique diagnostic character for the family Bogidiellidae and alone merits recognition of a new genus. The occurrence of Megagidiella azul in an isolated, inland cave habitat marks another exceptional biogeographic record of a bogidiellid amphipod from South America.

Bogidiella neotropica was described by Ruffo in 1952 after a single specimen of unknown sex, from Amazonia (Brazil). Both sexes have been found recently in the Guarico district, Venezuela. From the absence of secondary sexual differences in the male appendages it is clear that the species belongs to the subgenus Bogidiella s. str. The Venezuelan specimens are redescribed and illustrated.

Ho avuto di recente in studio da Rudolf Braun dell'«Institut fur spezielle Botanik» di Zurigo un piccolo lotto di Anfipodi raccolti in acque dolci della regione Amazonica da Harald Sioli dell'«Instituto Agronomico do Norte» di Belém do Pará (Brasile). Tra il materiale in gran parte costituito da specie del genere Hyalella, già ben noto per la fauna neotropicale e su cui riferirò in altra sede, rinvenni un unico esemplare che riconobbi appartenere ad una nuova specie del genere Bogidiella Hertzog fino ad ora conosciuto per le acque sotterranee di due sole località europee (Strasburgo e Skoplje). Dato il grande interesse biogeografico del nuovo reperto ho ritenuto opportuno segnalarlo nella presente nota. Ringrazio vivamente R. Braun e H. Sioli per avermi affidato Io studio di così interessante materiale.

A new troglobitic species of the amphipod family Artesiidae Holsinger, 1980 is described from a cave in the municipality of Santa Maria da Vitória, in the Brazilian state of Bahia, northeastern Brazil. Spelaeogammarus titan sp. nov. differs from the others in the genus by its body length, rising up to 18.3 mm, the antenna 1 with accessory flagellum 6-articulate, propodus of the first gnathopod 1.8 X longer than basis, the largest in the genus, coxa 5 with posterior lobe slightly concave, inner ramus of pleopods with 10 to 13 setae, outer ramus of uropod 3 with 22 simple setae, and telson with 1 apical plus 3 subapical stout setae in each lobe. With this study, the knowledge of Spelaeogammarus is improved to 5 species, all of them exclusive to caves in the northeastern Brazilian state of Bahia. A comparative table with the diagnostic characters of the species of Spelaeogammarus is provided.

Three new subterranean amphipods of the genus Spelaeogammarus da Silva Brum, 1975, are described from eastern Brazil, bringing the total number of species in the genus to four. Based on the examination of type-material of Spelaeogammarus bahiensis, a comparative diagnosis of all four species of Spelaeogammarus. including the new species Spelaeogammarus spinilacertus, Spelaeogammarus trajanoae, and Spelaeogammarus santanensis, is given. A diagnosis for the genus is also provided. The occurrence of these species in caves that are separated from each other in discontinuous karst areas is biogeographically significant for the family Bogidiellidae in continental South America.

There are five described species of the cave-dwelling amphipods of the genus Spelaeogammarus, all of them inhabiting caves on the Brazilian state of Bahia. A new species of this genus is here described, which is closely related to the already known species S. santanensis and S. titan. Spelaeogammarus sanctus sp. nov. differs from its congeneric species basically by the presence of more than 18 bifid setae on the dorsal margin of uropod 3 outer ramus and telson with one apical and two subapical stout setae, while the other species generally present less setae on the third uropod and more setae on telson. An identification key and an updated table of the Spelaeogammarus species diagnosis are provided, as well as a multivariate statistical approach of morphological variations among the species.

This paper deals with the description of Spelaeogammarus bahiensis n. g. n. sp. and of cave amphipod of the family Bogidiellidae from State of Bahia, Brazil. The new genus may be distinguished from the other two genera of the family by the following features: 1) body proporcionally less slender. 2) coxal plates well developed. 3) pleopodes with two branches well developed. 4) basipodites of the last three peraeopods very wide.
