January 2004 Newsletter of Invertebrate Conservation & Information Network of South Asia & the Invertebrate Special Interest Group, CBSG, South Asia Vol. 7 No. 1, January 2004 Invertebrate Pollinator Network of South Asia The IUCN/SSC South Asian Invertebrate Specialist Group (S Asian ISG) announces the formation of its first network – The Invertebrate Pollinator Network of South Asia (IPNSA). The objectives of this network is: • To identify all field biologists in South Asia working on invertebrate pollinators and network them to promote conservation particularly through field studies • To plan and execute activities on invertebrate pollinators such as training programmes, workshops and meetings • To bring out publications related to invertebrate pollinators for better exchange of ideas and, • To educate policy makers and general public about pollinators and their conservation. The IUCN SSC South Asian Invertebrate Specialist Group (S Asian ISG) formed IN THIS ISSUE in 2002 and hosted by Zoo Outreach Organisation, works in conjunction with Invertebrate Conservation and Information Network of South Asia (ICINSA). The Invertebrate Pollinator main objective of the Specialist Group is to encourage, and assist individuals, Network of South Asia institutions and agencies in South Asia to conserve invertebrates.

In terms of utility, pollinating invertebrates may be one of the most and nutritional security for significant groups since 1) the survival of a multitude of other organisms human welfare.

MADHYASTHA* Malacology Centre, Poornaprajna College, Udupi-576 101, Karnataka, India E-mail: [email protected];[email protected]; sps [email protected] INTRODUCTION Molluscs fonn an important constituent of leaf litter and soil biota. They are an ideal group for monitoring site specific environmental impact assessment studies because of their limited migration patterns. Majority of them remain undiscovered or under described, partly because of insufficient exploration and partly because of their often minute sizes (Emberton, 1995). Unfortunately, for the last 75 years or so, in South India, no attention has been paid for this important group with exceptions of some localized reviews and publications [(Tonapi and Mulhekar, 1963; Tonapi 1971; Subba Rao and Mitra, 1979, 1986; Madhyastha et ai., 2003, 2005; Mavinkurve et ai., 2004a, (in press); Sandhya et ai., (submitted)]. The works of Ramanan (1900) and Sathyamurthi (1960) are the preliminary source for those interested in the terrestrial molluscs of Tamil Nadu. This work is in continuation of the checklist for the land snails of the southern states that is being fonnulated (Mavinkurve et al., 2004b). STUDY AREA Situated on the southeastern side of the Indian peninsula, the state of Tamil Nadu has an area of 130,058 sq Ian. The landmass of the state can be divided into two natural divisions: (i) The eastern coastal plain (ii) The hilly region along the north and the west. Along the whole length of the western part, at a distance from the sea varying from 80 to 160 km runs the Western Ghats range, a steep and rugged mass averaging 1220 metres above the sea level.

  • Camaenid Land Snails from Western and Central Australia (Mollusca: Pulmonata: Camaenidae) Iv Taxa from the Kimberley, Westrau'rachia Iredale, 1933 and Related Genera
    Rec. West. Aust. Mus., Suppl. no. 17,1984 CAMAENID LAND SNAILS FROM WESTERN AND CENTRAL AUSTRALIA (MOLLUSCA: PULMONATA: CAMAENIDAE) IV TAXA FROM THE KIMBERLEY, WESTRAU'RACHIA IREDALE, 1933 AND RELATED GENERA ALANSOLEM* [Received 9 February 1983. Accepted 22 July 1983. Published 30 June 1984.] INTRODUCTION This is the fourth report on the semi-arid zone dominant land snails of Western and central Australia, which belong to the Camaenidae, sensu lato. It reviews 29 species level taxa in five genera. Twenty-two species and three genera are new. Most belong to Westraltrachia Iredale, 1933, a genus restricted to the south fringes of the Kimberley in limestone hills between Hawkstone Creek, a western tributary of the Meda Riv:er, and the Lawford Ranges east ofFitzroy Crossing. Six of the 21 taxa were previously known and 15 are new. Several related genera from the East Kimberley and adjacent portions ofthe Northern Territory contain eight species. New taxa are Mouldingia (one species in the Napier Range, one near Lake Argyle); Ordtrachia (four species between Lake Argyle and Nicholson); and Prototrachia (one species from east of Timber Creek Police Station, Northern Territory). Exiligada negriensis (Iredale, 1933), lives on the southern edges of Lake Argyle and ranges south about to the level of Nicholson. A total of12,292 adult specimens were measured: 9,787 belong to Westraltrachia and 2,505 to the related genera. Several very large sets were not measured to save time, and thus more than 14,000 specimens were studied. Part I (Solem, 1979) ofthis series covered genera with trans-Australian distributions (Hadra Albers, 1860; Xanthomelon von Martens, 1860; Damochlora Iredale, 1938; Torresitrachia Iredale, 1939), plus related Chloritis-like genera from eastern Australia.

ZooKeys 682: 1–94. https://doi.org/10.3897/zookeys.682.12999 Abstract Limestone hills are now gaining global conservation attention as hotspots for short-range endemic species. Levels of land snail endemism can be high at limestone hills, especially at hill clusters that are geographically isolated. In the State of Perak, Peninsular Malaysia, limestone hills have been opportunistically surveyed for land snails in the past, but the majority have yet to be surveyed. To address this knowledge gap, we systematically surveyed the terrestrial malacofauna of 12 limestone hills that, based on our opinion, are a representation of the limestone land snail assemblages within the State.

ZooKeys 865: 137–154. https://doi.org/10.3897/zookeys.865.36296 Abstract The genus Bellatrachia Schileyko, 2018 was described based on a specimen identified as Helix (Chloritis) pseudomiara Bavay & Dautzenberg, 1909. We concluded that the examined specimen is not that spe- cies, but Helix condoriana Crosse & Fischer, 1863. Therefore, (1) the type species of Bellatrachia must be replaced with Helix condoriana; (2) the species Helix (Chloritis) pseudomiara must be re-allocated to the genus Trichochloritis; (3) the erroneous treatment of the genus Trichochloritis by Schileyko(2007) needs to be corrected through the description of a new genus, Dentichloritis gen. nov. based on Helix brevidens Sowerby I, 1841. In addition, Chloritis microtricha Möllendorff, 1898 is treated as a synonym ofHelix condoriana, and further information on the genitalia of Chloritis (?) bifoveata (Benson, 1856) is presented.
