Distribution records of poorly-known species are currently the most explored theme in the Brazilian seabird literature. If properly evaluated, this kind of information can improve our knowledge on distribution, migration and status of occurrence of these species. In this note we present new records for six species of poorly-known seabirds in the Brazilian coast, reviewing distribution records and defining their status of occurrence in the country. We consider Chionis albus (Gmelin, 1789) a pseudo-vagrant in Brazil and define its status as a scarce seasonal visitor from southern South America. We present the first records of Leucophaeus atricilla (Linnaeus, 1758) for Trindade Island, and of Leucophaeus pipixcan (Wagler, 1831) for the state of Rio Grande do Sul, and determined that the former is a vagrant in eastern Brazil and the latter a vagrant across the country. Anous stolidus (Linnaeus, 1758) is a vagrant in southernmost Brazil. We were unable to determine if records of Chlidonias niger (Linnaeus, 1758) for Brazil and southern South America refer to vagrancy or pseudo-vagrancy. Additionally, we verified the occurrence of breeding individuals of Anous minutus Boie, 1844 on Martin Vaz Island and confirmed that there is no evidence of breeding on neighboring Trindade Island.

Micrurus silviae is a coralsnake with a triadal pattern, and is one of the eight species found in southern South America. In Paraguay there are six taxa recorded: M. altirostris, M. baliocoryphus, M. frontalis, M. pyrrhocryptus, M. corallinus, and M. lemniscatus carvalhoi. Here we present a record of M. silviae, an additional and seventh species for the country. Previously M. silviae was known only from Rio Grande do Sul state, in southern Brazil. The specimen was found in South American Mesopotamian Grasslands ecoregion, with natural grassland in the Department of Itapúa.

ABSTRACT Cabossous tatouay Desmarest, 1804 is considered a rare species in southern South America, and Rio Grande do Sul State, Brazil, records of the species are scarce and inaccurate. This study reports 40 localities for C. tatouay, and provides a map of the species' potential distribution using ecological niche modeling (ENM). The ENM indicated that in this region C. tatouay is associated with open grasslands, including the areas of "Pampas" and the open fields in the highlands of the Atlantic Forest. This study contributes to the information about the greater naked-tailed armadillo in southern Brazil, and provides data key to its future conservation.

Small Collection

Snails belonging to Biomphalaria genus were collected from some regions of Southern South America as follows: Resistencia, province of Chaco, Argentina; Assumpcion, Paraguay; Department of Maldonado of Caneloni, Uruguay; and Pôrto Alegre, Rio Grande do Sul, Brazil. The material was classified as Biomphalaria peregrina (Orbigny) twice from Uruguay and once in Brazil; B. tenagophila (Orbigny), from Argentina and Brazil; and B. straminea (Dunker) in Paraguay. Negative results were obtained from the exposition of the abone refered snail specimens to miracidia of S. mansoni from Pernambuco, Brazil.

This paper reports on part of the species of the marine isopod genus Serolis (Crustacea, Flabellifera, Serolidae) collected from benthic stations performed during one of the cruises of the Brazil ian Navy Oc/S "Almirante Saldanha" along southern South America. The species reported are Serolis polccris Richardson, 1911, Serolis elliptica Sheppard, 1933, Serolis uaperta Moreira, 1971, and Serolis foresti Bastida & Torti, 1970. A complete synonymy is given for each of these species, as well as the main distinctive characteristics enabling its ready recognition. Some remarks are provided on features not lengthned treated on previous accounts. The geographi cal distribution of all named taxa is given. Serolis uaperta is for the first time reported from off State of Rio Grande do Sul (Brazil) and Uruguay, extending considerably southernwards its southern limit of distribution. Both Serolis foresti and Serolis elliptica are also for the first time recorded from off Uruguay.

During a taxonomic revision of the genus Croton from the Pampas grasslands, some necessary taxonomic adjustments were identified and are here presented. The study was based on new collections, field work and analyses of protologues and type specimens. We treat C. allemii as a synonym of C. triqueter, C. stenotrichus as a synonym of C. hilarii, and we designate a lectotype for C. stenotrichus. Croton lombardianus is newly reported for Brazil and C. macrobothrys as a new record for the Atlantic Moist Forest in the state of Rio Grande do Sul. Updated information on the geographic distributions of these species is also provided.

A taxonomic study of the Blechnum occidentale species group in southern and southeastern Brazil (Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul) was carried out and eleven taxa were accepted (nine species, two hybrids). Four taxa are widely distributed in tropical America, three are widely distributed in South America, three are exclusive to southern South America, and one is restricted to Brazil. New records are presented for several taxa in states from southeastern Brazil, in other regions of the country, as well as in other countries. Taxonomic descriptions are presented for the whole genus and for all infrageneric taxa occurring in the study area as well as synonymies, lectotypifications, a new combination (Blechnum × leopoldense), a key for the identification of infrageneric taxa, comments and geographical distribution for each taxon.

Helminthological studies with Chelidae freshwater turtles in South America were conducted in Argentina, Uruguay and Brazil, where nematodes, digeneans and monogeneans were reported. In this context, the study aims to report new cases of gastrointestinal helminth parasites of Acanthochelys spixii, Hydromedusa tectifera, and Phrynops hilarii. A total of 65 hosts from the southern region of Rio Grande do Sul, Brazil, were examined. Seven taxa belonging to Nematoda, Digenea, and Monogenoidea have new cases on hosts Chelidae in South America, as well as a Nematoda and two Digenea have new host cases for Brazil. Thus, the study expands the knowledge about the diversity of helminths and the geographic distribution of taxa associated with Chelidae turtles.

Crossodactylus schmidti can be found in few localities of southern South America, occurring in Argentina, Brazil and Paraguay. In July 2011, one specimen of Crossodactylus schmidti was found in the municipality of Taquaruçu do Sul, Rio Grande do Sul state, Brazil. This is the second record of the species for Rio Grande do Sul and extends its known distribution ca. 35 km southwest from the closest known locality Parque Estadual do Turvo, municipality of Derrubadas. This record probably corresponds to the southern limit of distribution of the species, which would allow a reassessment of its conservation status.
