Horvathinia pelocoroides Montandon, 1911 was described as a new genus and species based on two specimens collected in Brazil, one from Minas Gerais deposited in the Naturhistoriska Riksmuseet (Stockholm) and the other from Rio Grande do Sul deposited in the Magyar Természettudományi Múzeum (Budapest) (Montandon 1911). Subsequently, nine additional species were described based on a single specimen each, collected at different localities in southern South America: H. doellojuradoi De Carlo, 1930; H. pelleranoi De Carlo, 1930; H. castilloi De Carlo, 1938; H. meyeri De Carlo, 1938; H. bollei De Carlo, 1958; H. lenti De Carlo, 1958; H. schubarti De Carlo, 1958; H. forsteri Lauck, 1958; and H. argemii Schnack, 1972 (Schnack & Estévez 2005).

Brasilochondria riograndensis gen. nov., sp. nov. (Copepoda, Chondracanthidae) a parasite of the flounder, Paralichthys orbignyanus (Valenciennes, 1839), is described. The new genus has a spherical head a post-mandibular "neck" and two pairs of modified biramous legs. In these respects, it resembles Argentinochondria patagonensis Etchegoin, Timi & Sardella, 2003. In the Argentine genus, however, the bulbous head has a medial constriction and the posterior of the female lacks the lateral extensions that are present in the new genus. Pseudolernentoma brasiliensis Luque & Alves, 2003, also resembles the new genus but it lacks the lateral extensions of the trunk and the latter is cylindrical rather than flat. The second leg of the new genus is small and the endopod is shorter than the exopod. The other two genera have large second legs with subequal rami.

Ditaxodon taeniatus is a striped, racer-like colubrid snake inhabiting grassland savannas in southern Brazil. This species was described as Philodryas taeniatus by the then curator of the Museum für Naturkunde der Humboldt-Universität zu Berlin (formerly Zoologisches Museum Berlin, ZMB), Wilhelm Peters, from a single specimen collected by Reinhold Hensel in Porto Alegre, Rio Grande do Sul. Peters’ description was published in a paper by Hensel (1868: 331) and, according to the International Code of Zoological Nomenclature (ICZN, 1999: Article 50.1, Recommendation 51E), the correct citation is Ditaxodon taeniatus (Peters in Hensel, 1868). Later, George A. Boulenger (1896: 124) transferred Philodryas taeniatus to the genus Conophis, and Alphonse R. Hoge (1958: 54) created for it the new genus Ditaxodon, which remains monotypic today.

A new genus and species of catshark is described based on a single specimen collected off Ambon in the Maluku Islands of eastern Indonesia. Akheilos suwartanai belongs to the subfamily Schroederichthyinae which differs from the other catsharks in a combination of: similar sized dorsal fins, supraorbital crests present, pseudosiphon present on claspers, broad subocular ridges under eyes, posterior nasal flaps present, tips of rostral cartilage fused into a rostral node. It represents the first record of this subfamily outside of the Americas. Akheilos differs from the other genus in the subfamily, Schroederichthys in a combination of: clasper groove not fused dorsally, ventral lobe of caudal fin produced, more intestinal valve turns, anal fin slightly larger than second dorsal fin, and in colour pattern.

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.

The new genus Neodrassex is proposed to include two new species of Gnaphosidae from Brazil. Neodrassex aureus sp. nov. is described from Amazonas, Paraná and Rio Grande do Sul states, and N. iguatemi sp. nov. is described from Paraná state. Neodrassex gen. nov. is characterized by small size, pale coloration, large anterior median eyes surrounded by black pigmentation, absence of a dorsal abdominal scutum in males and by the cheliceral dentition with 2-3 teeth on the promargin and 2-4 on the retromargin. The new genus is tentatively placed at the Leptodrassex group.

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.

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.
