None of the characters taken alone can s e r ve as a crite rion for the determination of the rank of a taxonomic category. Obj ective crite ria exist for the species only, due to the pres enc e of continuous variability within the species and in its absence b etween the species. " (B. A. Wainstein, Zool.

GENERAL INTRODUCTION The following systematic revisions of New Zealand taxa within the Arionacean subfamilies F l ammulininae Climo, 1969, Otoconchinae Cockerell, 1893 and Endodontinae Suter, 1913 (family Endodontidae Pilsbry, 1894) are based on quantitative reappraisals of shell morphology and studi es on radular and soft-part morphology. The last major revision of these New Zealand pulmonate taxa was presented by Suter (1 913) i n hi s Manual of the New Zealand Mollusca, and illustra ted in hi s Atlas of Plates which appeared in 1915. Suter' s work was, as were the great majority of earlier pulmonate systematic studies, based on studies of shell and radular morphology, and was the major contribution towards the erection of a systematic hierarchy which illustrated the indigenous nature of the New Zealand endodontid fauna.

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.

The malacological collection of the Universidade Federal de Santa Maria, curated by Dr. Carla B. Kotzian, has been recently donated to the Museu de Zoologia da Universidade de São Paulo (MZSP, Brazil). The collection is rich in well preserved specimens of terrestrial gastropods from central Rio Grande do Sul state, in southernmost Brazil. That region, centered in the municipality of Santa Maria, represents a transitional area between the Atlantic Rainforest and Pampas biomes and has been scarcely reported in the literature. Therefore, we present a taxonomical study of these specimens, complemented by historical material of the MZSP collection. Overall, we report 20 species, mostly belonging to the Stylommatophora, from which four represent new records for Rio Grande do Sul: Adelopoma brasiliense, Happia vitrina, Macrodontes gargantua, and Cyclodontina corderoi. The present report of C. corderoi is also the first from Brazil. Two introduced species were found in the studied material: Bradybaena similaris and Zonitoides sp. Key-Words. Diplommatinidae; Gastropoda; Helicinidae; Pulmonata; Stylommatophora. Resumo.

    Environmental factors affecting the distribution of land snails in the Atlantic Rain Forest of Ilha Grande, Angra dos Reis, RJ, Brazil Nunes, GKM.* and Santos, SB. Programa de Pós-Graduação em Ecologia e Evolução – PPGEE, Laboratório de Malacologia Límnica e Terrestre, Universidade do Estado do Rio de Janeiro – UERJ, Rua São Francisco Xavier, 524, PHLC, sala 224, CEP 20550-013, Rio de Janeiro, RJ, Brazil *e-mail: [email protected] Received November 30, 2010 – Accepted February 1, 2011 – Distributed February 29, 2012 (With 4 figures) Abstract The distribution and abundance of terrestrial molluscs are affected by environmental factors, but data are lacking for Brazilian land snails. The aim of this study was to understand the relationship between measured environmental factors and the land-snail species composition of two hillsides covered with Atlantic Rain Forest on Ilha Grande. On each hillside, five plots located at 100 m intervals between 100 to 500 m asl were chosen. Each plot was sampled by carrying out timed searches and collecting and sorting litter samples from ten quadrats of 25 × 75 cm. A range of environmental data was measured for each of the quadrats in a plot. A Cluster Analysis was carried out for the richness and abundance data. The environmental variables were analysed using a Pearson Correlation Matrix and Discriminant Analysis. Our results show that the two mountains are similar in species richness, but species composition and abundance are different, probably reflecting observed differences in environmental conditions. The environmental factors associated with compositional variation between the two mountains were: atmospheric temperature, soil temperature, litter depth, and relative air humidity.

We describe two new genera of land molluscs found under wet leaf litter in isolated fragments of a secondary native forest at the Hualpén Botanical Park (36º45´-36º49´ S, 73º9´-73º13´ W), University of Concepción, Chile. The new taxa are Pichikadi gen.n., of Punctidae, and Chellius gen.n., of Charopidae, with the following new species: Pichikadi hualpensis sp.n., and Chellius piramidalis sp.n. English diagnosis are presented for all taxa, together with an English identification key and English versions of figure captions and table headings. To facilitate subsequent studies and interpretations, we follow recent authors in using mainly shell characters, an approach that has favored the present taxonomic stability of the world’s land micromollusca. The diagnosis and observations are complemented with a key for the species of these families inhabiting continental Chile. Rev. Biol. Trop. 55 (2): 693-708. Epub 2007 June, 29. Key words: Charopidae, land snails, Punctidae, Pulmonata, Micromollusca, Stylommatophora. La importante diversidad que se está contando las especies dispersas en las grandes conociendo actualmente en los táxones de colecciones de los museos del mundo.
