A New Meghimatium Species from Vietnam (Gastropoda, Pulmonata, Philomycidae)
MALAKOLÓGIAI TÁJÉKOZTATÓ MALACOLOGICAL NEWSLETTER 2011 29: 51–54 A new Meghimatium species from Vietnam (Gastropoda, Pulmonata, Philomycidae) A. Varga Abstract: The author describes a new species of Philomycidae, from the rain forest of Northern Vietnam. Keywords: Gastropoda, Pulmonata, terrestrial slugs, Philomycidae, taxonomy, Vietnam. Introduction Coloration of live Meghimatium species is diverse and attractive (Schilthuizen, M. & Liew, T. S. 2008). The colour of alcohol-preserved specimens, however, fades and changes within a short period of time. Early authors have described numerous species of the genus found in Asia. These descriptions were based only on external characteristics, especially the coloration of pre- served slugs, leaving the examination of genitalia out of consideration (Collinge, 1901, 1903; Cockerell, 1890; Simroth, 1902). It was Hoffmann (1924) who critically revised and syn- onymized many of the described species.. Wiktor et al. (2000) followed the same principles. Meghimatium lucyenensis n. sp. (figs. 1–5) Material: Vietnam, Yên Bái Province, Luc Yen (Lu. c Yên) (Map. 1), fringe of the rain for- est next to a stream, from underneath stones, 05 December, 1971., leg. István Matskási & Map 1. Locality of Meghimatium lucyenensis n. sp. in Vietnam 51 György Topál. Holotype HNHM 92601/1, Paratype HNHM 92602/1 (Hungarian Natural History Museum, Budapest). Diagnosis: – Animal small-sized, genital system with large atrium, short and thick penis, short and thin vas deferens, short and thick-set vagina. Description (alcohol-preserved) (figs 1–2): The sexually mature slug is very small: the length of the preserved specimens are 23 (HT) and 22 (PT) mm. The colour of the body of the alcohol-preserved specimens is creamy. -

1. Field observation and laboratory observation We compiled all the data regarding the interaction between Plectostoma and its predators from our field observations conducted between October 2002 and January 2013 in Peninsular Malaysia and Sabah. Most of these observations were made during the day time. Whenever possible, field notes and photographs were taken when interactions between Plectostoma species and their predators were seen. We made five direct observations on the interactions between Plectostoma snails and their predators (Table S1). We found two Pteroptyx species larvae (Lampyridae) and an Atopos slug species (Rathouisiidae) attacking three Plectostoma species. Pteroptyx was seen to attack adult and juvenile Plectostoma snails by shell-apertural entry whereas Atopos were seen to attack adult Plectostoma snails by shell-drilling. Table S1.

Prólogo Uno de los objetivos fundamentales de la Alianza Centroamericana para el Desarrollo Sostenible, suscrita por los mandatarios de la región en el segundo semestre de 1994, lo constituye el dar un enfoque integrado para la construcción de un modelo de desarrollo sostenible a nivel regional, buscando un balance entre los aspectos políticos, económicos, sociales y ambientales, así como el fomentar espacios de participación para la sociedad civil en la construcción de estos procesos. La Comisión Centroamericana de Ambiente y Desarrollo (CCAD), como una de las principales organizaciones regionales de este marco estratégico, se enfoca hacia el cumplimiento de los compromisos ambientales de la Alianza y en la incorporación de los asuntos ambientales en las otras áreas contenidas en esta estrategia regional de desarrollo (política, económica y social). Una de las prioridades dentro de los compromisos en materia de ambiente y recursos naturales, lo constituye la conservación y manejo sostenible de la biodiversidad de la región, que por características muy particulares, como la posición geográfica en la región tropical del planeta, el ser un puente natural entre dos masas continentales, la ubicación entre dos océanos y en el mapa geológico, derivan para nuestra región una gran riqueza en biodiversidad, en un territorio relativamente pequeño. Nuestra obligación como centroamericanos, es el de conservar y hacer un uso inteligente de esta gran riqueza natural, respetando la capacidad de regeneración de nuestros ecosistemas y evitando la destrucción y agotamiento de los mismos, que también constituyen en el tiempo un derecho de las futuras generaciones. Valoramos profundamente lo que significa la extinción de una especie y sabemos que es para siempre, somos conscientes que hemos perdido en la región una diversidad muy grande de especies de flora y fauna, sobre las cuales poco o nada hemos aprendido, desaprovechando sus usos potenciales. -

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. -

David T. HOLYOAK1, Geraldine A. HOLYOAK1, Ricardo F. de LIMA2,3, Martina PANISI2 and Frazer SINCLAIR3,4 Recibidio el ... ABSTRACT Seven species of terrestrial Gastropoda are newly described from the island of São Tomé and six more from the island of Príncipe. The genera involved are Chondrocyclus (Cyclophoridae), Maizania and Thomeomaizania (Maizaniidae), Pseudoveronicella (Veronicellidae), Nothapalus (Achatinidae: subfamily undet.), Gulella and Streptostele (Streptaxidae), Truncatellina (Truncatellinidae), Afroconulus (Euconulidae), Principicochlea gen. nov., Principotrochoidea gen. nov., Thomithapsia gen. nov. and Thomitrochoidea gen. nov. (Urocyclidae). Most of these are from natural forest habitats and are likely to be single- island endemics. Apothapsia gen. nov. (Helicarionidae) is also described to accommodate two previously known species. Additional new island records are of ten species on São Tomé, one on Príncipe alone and two more on both islands. These include six species of "microgastropods" with wider ranges in tropical Africa that are likely to be hitherto overlooked parts of the indigenous fauna and six anthropogenic introductions; Pseudopeas crossei previously known only from Príncipe and Bioko is newly recorded on São Tomé.
