New troglobitic species of Benthana Budde-Lund, 1908 and Benthanoides Lemos de Castro, 1958 from iron-ore caves and their important record in the Amazon biome (Crustacea: Isopoda: Philosciidae).

A new cave-restricted species of Benthana and two cave-restricted species of Benthanoides are described from iron-ore caves located in the Serra dos Carajás complex, Pará state, in the Amazon biome. Benthana alba n. sp.

Supergroup F in terrestrial isopods: Horizontal transmission from termites?

Unlabelled: Horizontal transmission between distantly related species has been used to explain how infect multiple species at astonishing rates despite the selection for resistance. Recently, a terrestrial isopod species was found to be infected by an unusual strain of supergroup F . However, only of supergroup B is typically found in isopods.

New troglobitic species of Xangoniscus (Isopoda: Styloniscidae) from Brazil, with notes on their habitats and threats.

In the present work, five new species of Xangoniscus are described, increasing to eight the number of the known troglobitic species for the genus. Xangoniscus species can be distinguished from each other by the shape of pleonites epimera, the number and size of aesthetascs in the distal article of antennula, the modifications on pereopods, the shape of male pleopods and the proportion between uropod rami. Species from this genus are known for the states of Minas Gerais and Bahia with Xangoniscus aganju representing the northernmost occurrence, and X.

Two new species and new records of terrestrial isopods (Crustacea, Isopoda, Oniscidea) from Brazilian caves.

To date, approximately 190 species of terrestrial isopods are known from Brazil and only 14 are considered troglobiotic. After the examination of a large collection from caves in Bambuí and Una geomorphological areas, along the states of Bahia, Minas Gerais and Goiás, two new troglobiotic species were recognized. Pectenoniscus liliae Campos-Filho, Bichuette Taiti sp.

Two new species of Atlantoscia Ferrara Taiti, 1981 (Isopoda: Oniscidea: Philosciidae) from southern Brazil described in the light of integrative taxonomy.

The use of molecular data in association with classical taxonomy has helped to alleviate the taxonomic impediment through the discovery, delimitation and description of new species. Terrestrial isopods are the largest suborder of Isopoda; however, there are very few active taxonomists in this group and a representative part of the terrestrial isopods world diversity remains unexplored. The genus Atlantoscia comprises five species in which diagnostic characters are few and show subtle differences among the species.

Two new species of (Crustacea, Amphipoda, Hyalellidae) from state of Rio Grande do Sul, Southern Brazil.

There are 68 known species of Hyalella worldwide, with 23 occurring in Brazil. The state of Rio Grande do Sul, Southern Brazil, has the largest diversity of the genus in the country, with nine species recorded. The current study aimed to describe two new species of Hyalella from state of Rio Grande do Sul, both of them in the Northwest region of the state, one found in a small spring and another in an artificial pond.

A new genus of Trachelipodidae Strouhal, 1953 (Crustacea, Isopoda, Oniscidea) from the eastern Mediterranean.

Levantoniscus n. gen. is erected for two new species from Cyprus: Levantoniscus bicostulatus n.

Two new subterranean species of Hyalella Smith, 1874 (Crustacea: Amphipoda: Hyalellidae) from Brazil.

Two new species of Hyalella from Brazil are described. Hyalella veredae sp. n.
