Taxonomic revision of the genus Benthana Budde-Lund, 1908 (Isopoda: Oniscidea: Philosciidae)

The neotropical genus Benthana (Philosciidae) is reviewed. Fourteen species are redescribed: Benthana picta, B. olfersii, B. longicornis, B. schubarti, B. albomarginata, B. werneri, B. santosi, B. longipenis, B. bocainensis, B. moreirai, B. dimorpha, B. iporangensis, B. sulcata, and B. longicaudata. Additional characters were proposed for B. convexa, B. taeniata, B. serrana, B. trinodulata, B. araucariana, and B. cairensis. New records are provided for 13 species, and four new species are described: Benthana aimores sp. nov., Benthana goitacas sp. nov., Benthana tupinamba sp. nov. and Benthana canastraensis sp. nov.. Two Chilean species are considered incertae sedis. A pictorial key and distribution maps for the species are provided.

Review of Atlantoscia Ferrara & Taiti, 1981 (Crustacea: Isopoda: Oniscidea: Philosciidae) with new records and new species

The neotropical genus Atlantoscia Ferrara & Taiti, 1981 includes three species, A. floridana Van Name, 1940, occurring in coastal regions of Florida (USA), Brazil, Argentina, and Ascension and Saint Helena islands, A. rubromarginata Araujo & Leistikow, 1999 and A. petronioi Campos-Filho, Contreira and Lopes-Leitzke, 2012 from Brazil. Two new species from Brazil are here described, one from the state of Bahia and one from the state of São Paulo. All the new species have respiratory areas on pleopods 1–5 exopods. The specimens were collected in areas of Atlantic Forest and in cocoa (Theobroma cacao) plantations. New records of A. floridana and A. rubromarginata and distribution maps are presented.

Two new troglobitic species of Scleropactidae (Crustacea: Isopoda: Oniscidea) from Pará, Brazil

The South America Scleropactidae includes 53 nominal species distributed in 14 genera. In Brazil, there are 16 species recorded in the north and southeast regions. Here, two new species of Scleropactidae are described based on material collected in caves in the state of Para, both troglobitic and allocated in the genus Circoniscus. Circoniscus buckupi sp. nov. can be distinguished from its congeners by the long second article of antennal flagellum, inner endite of maxillula with a small hook-like spine at the apex, a long dactylar organ with pectinate apex conferring a knife-shaped appearance and the absence of schisma in adults. Circoniscus carajasensis sp. nov. can be distinguished from Circoniscus buckupi sp. nov. by the presence of schisma on pereionite 1 in adults and dactylar organ with a fringe appearance.

The genus Trichorhina Budde-Lund in Brazil, with description of seven new species (Isopoda, Oniscidea, Platyarthridae)

Seven new species of Trichorhina Budde-Lund, 1908 are described, six from Southeastern Brazil, T. biumbonata sp. nov., T. lenkoi sp. nov., T. myrmecophila sp. nov., T. orensis sp. nov., T. sexdens sp. nov., T. tropidocerata sp. nov., and one from Central Brazil, T. crassisetae sp. nov. An emended diagnosis for the genus and a key to the 19 species recorded from Brazil are provided. Trichorhina acuta Araujo & Buckup, 1994 is recorded to state of Mato Grosso do Sul.

A new species of Atlantoscia Ferrara & Taiti, 1981 (Oniscidea: Philosciidae) from Rio Grande do Sul, Brazil

To date the genus Atlantoscia Ferrara and Taiti, 1981 includes two species, A. floridana (van Name, 1940) and A. rubromarginata Araujo and Leistikow, 1999. The species Atlantoscia petronioi sp.n. is described on the basis of material collected in a coastal dune forest area of the southern Rio Grande do Sul state, Brazil. This new species is characterized by antenna with accentuate setose sulcus from the peduncle to the distal article of the flagellum, outer endite of maxillula with slender seta among the outer group teeth and accessory tooth, one trifid tooth in the inner group, and male pleopod 1 endopod with distal part pointed and subapically not swollen.

The genus Dubioniscus Vandel, 1963 (Oniscidea, Dubioniscidae) with descriptions of two new species from Brazil

Before the present study, the genus Dubioniscus included four species occurring in Central and South Americas. The examination of Dubioniscus delamarei, D. marmoratus and D. negreae allowed us to revise the genus and to move D. goeldii to Calycuoniscus. Moreover, two new species are described, D. depressus n. sp. from the state of São Paulo, and D. elongatus n. sp. from the state of Rio de Janeiro, Brazil. http://zoobank.org/urn:lsid:zoobank.org:pub:1D2B9F44-96EE-48A6-A8DE-D24F190F9AF3.

A new species of Trichorhina Budde-Lund, 1908 (Isopoda: Oniscidea: Platyarthridae) from Paraná caves, southern Brazil

The genus Trichorhina Budde-Lund, 1908 in Brazil includes 22 described species, four of which occur in caves. The present work aims at describing the first cave species for the state of Parana. Trichorhina kaingangi n. sp. was collected in Agua Boa cave, municipally of Almirante Tamandare, and Ermida Paiol do Alto cave, municipally of Adrianopolis, both in the Acungui karst area.

Two new species of Benthana Budde-Lund, 1908 (Crustacea: Isopoda: Philosciidae) from Brazil

Two new species of Benthana Budde-Lund, 1908 are described from material collected in the states of Rio de Janeiro and Paraná, Brazil. Benthana schmalfussi n. sp. is distinguished by the shape of the male pleopod 1 exopod, whereas Benthana guayanas n. sp. is distinguished by the noduli laterales d/c coordinates and shape of the male pleopod 1 exopod. A new method is given for defining the shape of the outer distal margin of the male pleopod 1 exopod. http://zoobank.org/urn:lsid:zoobank.org:pub:A79EDB3B-F7AC-47A3-ADD8-DA00FFAD69CB

A new species and first record of Androdeloscia (Oniscidea: Philosciidae) from Colombia

ABSTRACT The genus Androdeloscia includes 24 Neotropical species distributed in Central and South America. This study describes the new species Androdeloscia colombiana sp. nov. from El Chorro, Soplaviento, and from the Botanical Garden Guillermo Piñeres, Turbaco, Bolívar, Colombia. This is the first record of the genus in Colombia. http://zoobank.org/urn:lsid:zoobank.org:pub:AEA56E26-1F6D-4DDA-BA02-D73DE9FAD198
