Gonyostomus elinae is a new species collected from the Caboclos region of São Paulo, Brazil, extending the distribution of the genus south to the cavern environ- ment of the central Atlantic rainforest. The new species differs from the other three species in the genus in having a different colour pattern of the shell, a wider um- bilicus, smoother sculpture, and a wider aperture having a straight inner lip. The species can be already classified as endangered. Luiz Ricardo L.

Av. Benavides 5400, Surco. P.O. Box 18-131. Lima, Perú. Abstract: Peru is an ecologically diverse country, with 84 life zones in the Holdridge system and 18 ecological regions (including two marine). 1910 molluscan species have been recorded. The highest number corresponds to the sea: 570 gastropods, 370 bivalves, 36 cephalopods, 34 polyplacoforans, 3 monoplacophorans, 3 scaphopods and 2 aplacophorans (total 1018 species). The most diverse families are Veneridae (57spp.), Muricidae (47spp.), Collumbellidae (40 spp.) and Tellinidae (37 spp.). Biogeographically, 56 % of marine species are Panamic, 11 % Peruvian and the rest occurs in both provinces; 73 marine species are endemic to Peru. Land molluscs include 763 species, 2.54 % of the global estimate and 38 % of the South American esti- mate. The most biodiverse families are Bulimulidae with 424 spp., Clausiliidae with 75 spp. and Systrophiidae with 55 spp. In contrast, only 129 freshwater species have been reported, 35 endemics (mainly hydrobiids with 14 spp. The paper includes an overview of biogeography, ecology, use, history of research efforts and conser- vation; as well as indication of areas and species that are in greater need of study. -
Primer Registro Del Paleoceno En El Uruguay: Paleosuelos Calcareos Fosiliferos En La Cuenca De Santa Lucia
Revista Brasileira de Geociéncias 27(3):295-302, setembro de 1997 PRIMER REGISTRO DEL PALEOCENO EN EL URUGUAY: PALEOSUELOS CALCAREOS FOSILIFEROS EN LA CUENCA DE SANTA LUCIA SERGIO MARTÍNEZ ; GERARDO VEROSLAVSKY & MARIANO VERDE* ABSTRACT PALEOCENE FOSSILASSOCIATIONSIN CALCAREOUS PALEOSOLS FROM SANTA LUCIA BASIN (URUGUAY) For the first time, the Paleocene is recorded in Uruguay, developed at the central area of Santa Lucia Basin. It is represented by non depositional events, recognized as carbonatic paleosols, containing a characteristic fossil record. Up to date these carbonate deposits were included in the deposits known as "Calizas del Queguay" (Queguay Limestones), and considered as belonging to Mercedes Formation (Upper Cretaceous), interpreted as lacustrine facies laterally associated with sandstone and conglomérate fluvial facies. However, researches conducted by the authors have shown that these deposits are the product of calcretization processes that affected the Mercedes Formation clastic sedimentites. The calcareous, fossiliferous paleosols were developed overimposed at the top of the groundwater calcretes. The fossils found are: pulmonate gastropods (Eoborus charruanus), endocarps of Celtis santosi, rizoliths, and bee nests (Celliforma spp.). This association is typical of paleosols and the age of all the fossils is Tertiary. The gastropods have very similar representatives at the Paleocene of the São José de Itaboraí Basin (Rio de Janeiro, Brazil), being the Uruguayan and Brazilian representatives of Eoborus the only species known of this genus. The Celtis santosi endocarps are present only at these two basins. Then, a Paleocene age is postulated for the paleosols and for the event of calcretization, developed under a warm and arid environment. Key words: Paleocene, gastropods, ichnofossils, seeds, Queguay Limestones, Uruguay RESUMEN Por primera vez se reconocen registros del Paleoceno en el Uruguay, los que se desarrollan en la región central de la Cuenca de Santa Lucía. -

Os caracteres dos animais do nosso material coincidem em grande parte com os de Strophocheilus oblongus mus- culus Becquaert, 1948, subespécie até agora somente citada para a Argentina e Paraguai. Para o nosso estudo seguimos a monografia elaborada por Bec quaert (1948) sôbre a revisão da família Strophocheilidae. Dela nos servimos também para a discussão e comentários. Grande auxílio nos prestou a excelente coleção malacológica existente no Departamento de Zoologia da Secretaria de Agricultura de São Paulo, estudada pelo próprio Becquaert. Agradecemos ao Dr. Celso Paulo Jaeger o fornecimento de vários caracóis; ao Dr. Lindolpho Guimarães e ao Lic. José Luiz Moraes Le me também agradecemos pelas facilidades proporcionadas para a con sulta da coleção malacológica do Departamento de Zoologia da Se cretaria de Agricultura do Estado de São Paulo.

The genus Ferussac, 1814, occur (Ferussaciidae Bourguignat, 1883). most C. acicula is well-known common one, (O.F.

The nomenclature of the second, far more local species has been the subject of much dispute. This species has a shell similar to that of C. acicula, but and broader instead of larger relatively (5-7 x 1.9 mm 4.5-5.5 x 1.2 mm), and with the about half instead of about third of the total In aperture forming a height. addition, the columella is clearly more truncate at the base (figs 1-2; Kerney & Cameron, 1979: 149-150; Falkner, 1990: 169, figs 1, 5; Turner et al., 1998: 237-238).

Comparative Analysis of Chromosome Counts Infers Three Paleopolyploidies in the Mollusca
GBE Comparative Analysis of Chromosome Counts Infers Three Paleopolyploidies in the Mollusca Nathaniel M. Hallinan* and David R. Lindberg Department of Integrative Biology, University of California Berkeley *Corresponding author: E-mail: [email protected]. Accepted: 8 August 2011 Abstract The study of paleopolyploidies requires the comparison of multiple whole genome sequences. If the branches of a phylogeny on which a whole-genome duplication (WGD) occurred could be identified before genome sequencing, taxa could be selected that provided a better assessment of that genome duplication. Here, we describe a likelihood model in which the number of chromosomes in a genome evolves according to a Markov process with one rate of chromosome duplication and loss that is proportional to the number of chromosomes in the genome and another stochastic rate at which every chromosome in the genome could duplicate in a single event. We compare the maximum likelihoods of a model in which the genome duplication rate varies to one in which it is fixed at zero using the Akaike information criterion, to determine if a model with WGDs is a good fit for the data. Once it has been determined that the data does fit the WGD model, we infer the phylogenetic position of paleopolyploidies by calculating the posterior probability that a WGD occurred on each branch of the taxon tree. Here, we apply this model to a molluscan tree represented by 124 taxa and infer three putative WGD events. In the Gastropoda, we identify a single branch within the Hypsogastropoda and one of two branches at the base of the Stylommatophora. -
