ZooKeys 453: 1–17. doi: 10.3897/zookeys.453.8605 Abstract Two new species of the genus Zilchistrophia Weyrauch, 1960 are described from Eastern Ecuadorian rain forest: Zilchistrophia hilaryae sp. n. and Z. shiwiarorum sp. n. These two new species extend the distribu- tion of the genus considerably northwards, because congeners have been reported from Peru only. For the first time we present anatomical data (radula, buccal mass, morphology of the foot and the genital struc- ture) of Zilchistrophia species. According to these, the genus belongs to the family Scolodontidae, sub- family Scolodontinae (=“Systrophiini”). The previously assumed systematic relationship of Zilchistrophia with the Asian Corillidae and Plectopylidae based on the similarly looking palatal plicae is not supported.

Biodiversidad De Gasterópodos Terrestres (Mollusca) En El Parque Biológico Sierra De San Javier, Tucumán, Argentina
Biodiversidad de gasterópodos terrestres (Mollusca) en el Parque Biológico Sierra de San Javier, Tucumán, Argentina María José Miranda & María Gabriela Cuezzo CONICET-Facultad de Ciencias Naturales, Universidad Nacional de Tucumán, Miguel Lillo 251, 4000 Tucumán, Argentina; [email protected], [email protected] Recibido 08-III-2009. Corregido 12-III-2010. Aceptado 08-IV-2010. Abstract: Biodiversity of land gastropods (Mollusca) in Sierra de San Javier Park, Tucumán, Argentina. Studies related to land mollusk diversity in tropical and subtropical forests are scarce. To assess this, a study on land snail diversity of subtropical cloudforest (Yungas) and dry forest (Chaco) areas of Sierra de San Javier Park, Tucumán, Argentina, was carried out. Taxonomic identifications were performed to species level and built a species per stations data matrix to analyze diversity patterns on qualitative and quantitative samples processed from 10x10m quadrates in altitudinal transects. Non parametric analysis (ICE, ACE, Chao 1 and Chao 2) were used to estimate the true diversity of the area, as well as the degree of undersampling and spatial aggregation of the data. Diversity was also calculated using Shannon, Simpson, Whittaker and Jaccard indices. The richness of the San Javier Park was estimated to be 32 species distributed into 13 families and 21 genera. From the total number of species collected, a single one belongs to Caenogastropoda, while the rest of the species are classified into Pulmonata Stylommatophora and Systellommatophora. The most representative family was the micromol- lusc Charopidae, while the most relatively abundant species was another micromollusc snail, Adelopoma tucma. Richness and diversity were slightly more elevated in dry forest areas of the Chacoan Ecoregion than in cloud forest areas of Yungas. -

[Taxonomy of terrestrial gastropods from the Quaternary of Argentina.] Revista Española de Paleontología, 26 (2), 101-133. ISSN 0213-6937. ABSTRACT This systematic review synthesizes our updated knowledge of 33 species and subspecies of Stylomatophoran gastropods, which belong to the genera Gastrocopta, Succinea, Radiodiscus, Retidiscus, Rotadiscus, Cecilioides, Austroborus, Megalobulimus, Bulimulus, Discoleus, Naesiotus, Plagiodontes, Spixia, Scolodonta, Miradiscops and Epiphragmophora. We provide published and unpublished records of the terrestrial molluscan taxa and a critical review, including data from the most important collections deposited in institutions from Argentina and abroad. All the taxa described have modern representatives; only two, Succinea rosariensis and Scolodonta argentina, still require confirmation regarding their taxonomic validity. The genera with confirmed older than Quaternary records are Austroborus, Megalobulimus, Radiodiscus, Rotadiscus and Succinea, which occur since the Paleoge- ne. Regarding the modern geographical distribution, well known records involve part of Argentina (Subtropical and Pampean Dominia of the Guayanian-Brazilian Subregion and the Central Dominion of the Andean Subre- gion, both in the Neotropical Region). -

The specimens were found in the Argentine Precordillera (Quebrada San Isidro, Mendoza province, Argentina), at 2.000 m, near the typical locality of the species, here restricted to the Angostura or garganta (gullet) of Villa Vicencio and Casa de Piedra. It is the southernmost distribution of the genus. This snail has a shell of medium size, planispiral, with six whorls; radula with central plate tricuspid, and latero-marginal teeth aculeate, formula: 13 – C – 13; vagina short, spermathecal duct reaching the distal extreme of the vagina, near the atrium; penial sheath long, penis occupying most of the penial sheath, epiphallus with a retractor muscle adhered to its extreme, large and quadrangular gland attached to the penial sheath; atrium very short.

There are 42 taxa listed, of which the following species are recorded for the fi rst time from the island: Allopeas gracile (Hutt on, 1834), A. micra (d’Orbigny, 1835), Beckianum beckianum (L. Pfeiff er, 1846), Bulimulus diaphanus fraterculus (Potiez & Michaud, 1835), De- roceras laeve (Müller, 1774), Sarasinula marginata (Semper, 1885), Streptostele musaecola (Morelet, 1860) and Veronicella sloanii (Cuvier, 1817).

Reproductive System, Mating Behavior and Basic Ecology of an Extremely Rare Tropical Snail: Drymaeus Tripictus (Stylommatophora: Bulimulidae)
Reproductive system, mating behavior and basic ecology of an extremely rare tropical snail: Drymaeus tripictus (Stylommatophora: Bulimulidae) Zaidett Barrientos Laboratorio de Ecología Urbana, UNED, 2050 San José, Costa Rica; [email protected], [email protected] Received 06-IV-2015. Corrected 20-VIII-2015. Accepted 21-IX-2015. Abstract: Very little is known about the ecology and biology of Drymaeus tripictus, an extremely rare and endemic land snail species from Costa Rican highlands. I studied the ecology and reproductive biology of D. tri- pictus from April 2009 through June 2010 in an old forest, a young forest and a Cupressus lusitanica plantation in central Costa Rica. Every three months I visited each habitat and collected specimens in 20 random sampling plots (3x3 m2 each). I observed the snail’s activity and microhabitat preference in the field, and in the labora- tory I recorded high definition videos of its mating behavior and analyzed reproductive morphology with light microscopy. The snail is more abundant in the old forest (0.017 ind./m2) and prefers leaves with little epiphyllous cover (0-25 % cover, chi-square test, p <0.0001). During the dry season the snails become active between 20:00 pm and 8:00 am (chi-square = 22.65, df=3, p < 0.0001); they are inactive mainly during the afternoon (11:00 am to 16:59 pm). I found active individuals mostly on the upper side of leaves, where they feed (Chi-square =6.76, df=1, p = 0.0093). Mating is unilateral, by shell mounting, with cryptic phallus intromission and without role switching or multiple mating. -
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
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.
