This work provides new information on agelasid sponges found on the continental shelf off northern Brazil. Agelas sceptrum (Lamarck, 1815) and Agelas wiedenmayeri Alcolado, 1984 have their first record for the Brazilian coast. Agelas dispar Duchassaing & Michelotti, 1864 and Agelas schmidti Wilson, 1902, previously recorded from Brazil, are cited for the first time off the mouth of the Amazon River.

We report new records of the White-Tailed Deer (Odocoileus virginianus) in Brazil based on specimens deposited in scientific collections. These new records expand the known geographic distribution of the species in Brazil southwards in the states of Roraima and Amapá, the latter the first record of the species below the equator line in Brazil, and register it for the first time in the state of Amazonas. These records contribute to increase the knowledge of the geographical distribution of O. virginianus in Brazil and highlights the importance of museum collections as a source of biogeographic and ecological data.

The genus Pisinna Monterosato, 1878 (Anabathridae Ponder, 1988) is reported from the Brazilian coast for the first time. Pisinna bicincta n. sp. is found off Esp rito Santo State (65 67 m depth) on the Brazilian continental shelf. It is diagnosed by its pupiform shell, with subsutural depression, two spiral bands (one white and one orange), dome-shaped paucispiral protoconch sculptured with about 17 spiral rows of minute flat pits, teleoconch with about 22 oblique axial cordlets, and aperture with columellar tooth.

Potimirim potimirim (Müller, 1881), a species of coastal freshwater shrimp, is recorded for the first time from the state of Rio Grande do Norte, northeastern of Brazil, where it was collected in a small tributary of the Potengi River. This record extends the distribution of this species about 220 km north along Brazilian coast. New records, such as this, reinforce the need for greater research efforts in the northeastern freshwater ecosystems of Brazil to provide better understand the region’s biodiversity and establish better parameters for conservation actions.

The reef system off the Amazon River mouth extends from Amapá state to Maranhão state along the Brazilian Equatorial Margin, encompassing more than 10,000 km2 of rhodolith beds and high-relief hard structures on the outer shelf and upper slope. This unique hard bottom mosaic is remarkable for being influenced by the turbid and hyposaline plume from the world’s largest river, and also for representing a connectivity corridor between the Caribbean and Brazil. Bryozoans were recently recognized as major reef builders in the Southwestern Atlantic, but their diversity off the Amazon River mouth remained unknown. Here, we report on recent collections obtained from 23 to 120 m depth in Northern Brazil. Sixty-five bryozoan taxa were characterized using scanning electron microscopy, including 57, five and three taxa of Cheilostomatida, Cyclostomatida and Ctenostomatida, respectively. Cribrilaria smitti and three genera (Cranosina, Glabrilaria and Thornelya) are new records for Brazil, and 13 new species are herein described: Antropora cruzeiro n. sp., Cranosina gilbertoi n. sp., Cribrilaria lateralis n. sp., Crisia brasiliensis n. sp., Glabrilaria antoniettae n. sp., Micropora amapaensis n. sp., Parasmittina amazonensis n. sp., Plesiocleidochasma arcuatum n. sp., Poricella bifurcata n. sp., Pourtalesella duoavicularia n. sp., Stephanollona domuspusilla n. sp., Therenia dianae n. sp., and Thornelya atlanticoensis n. sp. Our results highlight the biodiversity significance of the Amazon reefs and the need for more comprehensive sampling to clarify the role of bryozoans in modern turbid-zone reefs and rhodolith beds.

This paper reports the occurrence of four deep waters shrimps of the family Solenoceridae in the southwestern Atlantic, Brazil. The rare Hadropenaeus modestus is collected for the second time from Brazilian waters after 138 years, filling the gaps on its distributional pattern. Mesopenaeus tropicalis is a new register for Potiguar basin, although it is common along Brazilian coast. Hymenopenaeus chacei and H. laevis are recorded for the first time in southwestern Atlantic. The records of these species in the southwestern Atlantic are an important advancement to raise the knowledge of the deep-sea shrimps.

Abstract: A Longnose stingray Hypanus guttatus (Bloch & Schneider, 1801) embryo with a major asymmetrical morphological abnormality to its pectoral fin was obtained from commercial shrimp fisher's bycatch, off the coast of the Amazon River Mouth in northern Brazil. The specimen and the deformity, which would presumably have impeded its long-term survival, are described and documented in detail. We herein provide the first report of an abnormal individual of this species for the Brazilian coast.

Two new species in the genera Thyone and Havelockia are described and illustrated based upon specimens collected from off the southeastern Brazilian coast. Thyone florianoi sp. nov. is characterized by having two pillared body wall tables with four-holed discs and introvert with multilocular tables. Thyone crassidisca is recorded herein for the first time from the South Atlantic Ocean (Brazil). Havelockia mansoae sp. nov. is distinctive in having two pillared body wall tables with four-holed discs and introvert with plates. This is the first record of the genus Havelockia from Brazilian waters.

This work deals with haplosclerid sponges off the coast of Maranhão State, northeastern coast of Brazilian shelf (southwestern Atlantic). A new species is described, Haliclona (Halichoclona) lernerae. Four species are recorded for the first time for the Brazilian coast: Amphimedon caribica (Pulitzer-Finali, 1986); Niphates lutea Lehnert & Van Soest, 1999; Neopetrosia subtriangularis (Duchassaing, 1850) and Petrosia (Petrosia) weinbergi Van Soest, 1980. Three species were recollected from the southwestern Atlantic and have their geographic distribution extended on the Brazilian coast: Callyspongia (Cladochalina) vaginalis (Duchassaing & Michelotti, 1864), Oceanapia bartschi (De Laubenfels, 1934) and Xestospongia muta (Schmidt, 1870). Two species were collected for the first time from the Maranhão State Coast: Niphates erecta Duchassaing & Michelotti, 1864 and Neopetrosia proxima (Duchassaing & Michelotti, 1864). A taxonomic study of those samples is given, including description, illustrations and geographic distribution.

Sigmodontine rodents are well represented in northwestern Argentina, but information regarding their distribution in La Rioja is scarce. We add new information for seven species from seven localities in the Famatina range. These new records were obtained using both captures and owl pellet analysis. We cite the first record of Neotomys ebriosus in La Rioja. The collection locality is unusual for this species because of its low altitude and xeric conditions. Other notable results include the second record of Abrothrix andinus and of the genus Oligoryzomys at the province.

We present a checklist of 278 species of reef fishes recorded along the coastline of Santa Catarina state, the southernmost limit of distribution of tropical ichthyofauna on the coast of Brazil. Twelve new species records for this state are presented: Acanthurus coeruleus, Acanthurus monroviae, Apogon americanus, Cantherhines macrocerus, Chaetodon sedentarius, Chromis flavicauda, Clepticus brasiliensis, Decapterus punctatus, Gymnothorax vicinus, Herpetoichthys regius, Muraena retifera and Stegastes partitus. Stegastes partitus and H. regius are reported for the first time, respectively, from the Southwestern Atlantic and for the coastal part of this region, while Acanthurus monroviae is reported for the second time for the Southwestern Atlantic. We present habitat distribution, trophic structure and comment on biogeographic affinities of this transitional region, discussing both remarkable species presences and absences.
