Biota Neotropica é uma revista do Programa BIOTA/FAPESP-O Instituto Virtual da Biodiversidade, que publica resultados de pesquisa original, vinculada ou não ao programa, que abordem a temática caracterização, conservação e uso sustentável da biodiversidade na região Neotropical. Biota Neotropica is an electronic, peer-reviewed journal edited by the Program BIOTA/FAPESP: The Virtual Institute of Biodiversity. This journal's aim is to disseminate the results of original research work, associated or not to the program, concerned with characterization, conservation and sustainable use of biodiversity within the Neotropical region.

La Coronilla-Cerro verde has been proposed as the first marine protected area in Uruguay. As part of a detailed benthic biodiversity assessment at the reserve, we analyzed the ophiuroid fauna collected in the intertidal and shallow subtidal during 2005 and 2006. Three species of ophiuroids were identified: Amphioplus lucyae, Amphipholis squamata and Amphiodia sp. Only two species belonging to the genus Amphiodia (A. pulchella and A. planispina) have been previously mentioned for Uruguayan waters, indicating that the unidentified species found in this study constitutes a previously unreported species.
Shallow water Asteroidea and Ophiuroidea of Uruguay: composition and biogeography
Revista de Biología Tropical, 2008
Asteroidea (five species) and Ophiuroidea (18 species) recorded along the Uruguayan littoral (up to 50 m depth) are summarized and their distributional pattern are discussed. Species are gathered into four groups: 1) A. taxa distributed from North/South Carolina, or from the Caribbean Sea, to Southern Buenos Aires Province (Argentina), B. species ranging from North/South Carolina, Florida, São Paulo, to the mouth of Rio de la Plata, 2) species ranging from Rio de Janeiro south to the San Matias Gulf, 3) taxa recorded from Chile or from Antarctic/Subantarctic waters north to Uruguay, 4) a single cosmopolitan species. While ophiuroids are represented in each one of the mentioned groups, asteroids are restricted to the first one. As it happens with other elements of the Uruguayan fauna, this complex pattern is a consequence of the confluence of the warm Brazilian and the cold Malvinas (Falkland) currents, and of the discharge of fresh, muddy waters of the Rio de la Plata.

The family Anguidae contains three subfami-lies: Gerrhonotinae, Anguinae, and Diploglossinae. In Brazil, there are four described anguid species, all from the subfamily Diploglossinae. Herein, we present the first records of Diploglossus lessonae Peracca, 1890 from the state of Sergipe and new records for the states of Paraíba and Ceará. The records compiled here for the Caatinga can reveal a pattern of widely distributed species in the biome. Key words: lizards; Diploglossinae; Sergipe; Caatinga; Atlantic Forest
A new, but probably extinct, species of Cnemidophorus (Squamata, Teiidae) from Uruguay
The Herpetological Journal, 2009
A new species of Cnemidophorus related to the lacertoides group is described. The new taxon is distinguished from all other species of the genus by the following combination of character states: 81-98 granular dorsal scales across midbody; 201-206 dorsal scales along midline from nape to rump in males, 208-229 in females; 10 longitudinal rows of ventral scales in both sexes; 19-22 femoral pores in total; 13-15 subdigital lamellae under fourth finger, 20-25 lamellae under fourth toe; 3-4 supraoculars on each side; reduced expression of the "lacertoides pattern", which may be absent and replaced by a broad greenish mid-dorsal stripe on a brownish-grey background; ventral surfaces of head, body, limbs and tail pearly white, with the most lateral ventral scales of the body completely dark along the belly. The new species also exhibits some anatomical differences from its most closest related species, C. lacertoides. The hyobranchial apparatus of Cnemidophorus new sp. has a pair of short cartilaginous second ceratobranchials, articulated behind the basihyal-first ceratobranchial joint. This structure is absent in the hyobranchial apparatus of C. lacertoides sensu stricto which, moreover, has hypohyals that are relatively longer than in the new species. The new taxon is known only from the type locality, Cabo Polonio, Rocha Department, on the Atlantic coast of Uruguay, in a habitat of rocky grassland. Records of individuals are lacking from three decades to date and detailed field surveys in recent years in search of the lizard were unfruitful. We assume that this taxon is probably extinct. The pressure of increased human presence on the limited suitable habitat in the Cabo Polonio region could have caused its extinction.

Several new records of the harvestman Geraeocormobius sylvarum Holmberg (Opiliones, Gonyleptidae, Gonyleptinae) from the Argentinean provinces of Misiones, Corrientes, Chaco and Tucumán, and the Brazilian states of Paraná, Santa Catarina and Rio Grande do Sul are provided. Most known localities spread over the Paranense Biogeographic Province, while captures in northwestern Argentina represent a 640 km disjunction with the species core area (northeastern Argentina -southeastern Brazil). Some nomenclatural comments and a brief discussion on the causes of the disjunction are also given.
