Eleven species of Glessulinae belonging to the genera Glessula Martens, 1860 (three species) and Rishetia Godwin-Austen, 1920 (eight species) are reported from Nepal, six of which are new to science and are described here, viz., G. tamakoshi Budha & Backeljau, sp. n., R. kathmandica Budha & Backeljau, sp. n., R. nagarjunensis Budha & Naggs, sp. n., R. rishikeshi Budha & Naggs, sp. n., R. subulata Budha & Naggs and R. tribhuvana Budha, sp. n. and two are new records for Nepal viz. G. cf. hebetata and R. cf. mastersi. The relation between the shell height-width ratio and the structure of the proximal part of the male reproductive organs in Glessulinae is explored. Illustrations and a key for the identification of the Nepalese Glessulinae are provided, including the first record of a spermatophore in Rishetia. New taxa: Glessula tamakoshi n. sp. n., Rishetia kathmandica n. sp., Rishetia nagarjunensis n. sp., Rishetia rishikeshi n. sp., Rishetia subulata n. sp., Rishetia tribhuvana n. sp. 28 pp., 14 figs, gr. 8.

This is the very first checklist of the terrestrial gastropods of Nepal. It includes 138 species and six subspecies, of which 22 species are endemic and four are introduced.

The collection of land caenogastropod snails in the genus Cyclophorus Monfort, 1810 housed in the Natural History Museum, London (NHM), includes 52 type lots. Lectotypes have been designated for 43 available species-level names to stabilize existing nomenclature, two previously designated lectotype, two holotypes, one paratype, one syntype, one possible syntype and two paralectotypes are also listed. A complete catalogue of the Cyclophorus types in NHM, London is provided for the first time. 56 pp., 23 color pls, gr. 8 [16.3 x 23.7 cm].

All known taxa of the genus Endothyrella Zilch, 1960 (family Plectopylidae) are reviewed. Altogether 23 Endothyrella species are recognized. All species are illustrated and whenever possible, photographs of the available type specimens are provided. Five new species are described: E. angulata Budha & Páll-Gergely, sp. n., E. dolakhaensis Budha & Páll-Gergely, sp. n. and E. nepalica Budha & Páll-Gergely, sp. n. from Nepal, E. robustistriata Páll-Gergely, sp. n. from the Naga Hills, India, and E. inexpectata Páll-Gergely, sp. n. from Sichuan, China. Helix (Plectopylis) munipurensis Godwin-Austen, 1875 is synonymized with Helix (Plectopylis) serica Godwin-Austen, 1875, and Plectopylis (Endothyra) gregorsoni Gude, 1915 is synonymized with Helix (Plectopylis) macromphalus W. Blanford, 1870. Plectopylis plectostoma var. exerta Gude, 1901 is a synonym of Plectopylis plectostoma var. tricarinata Gude, 1896, which is a species in its own right. Five species of the genus Chersaecia viz. Plectopylis (Chersaecia) bedfordi Gude, 1915, Helix (Plectopylis) brahma Godwin-Austen, 1879, Helix (Plectopylis) Oglei Godwin-Austen, 1879, Helix (Plectopylis) serica Godwin-Austen, 1875, and Plectopylis (Endothyra) williamsoni Gude, 1915 are moved to Endothyrella. The holotype of Plectopylis hanleyi Godwin-Austen, 1879 seems to be lost; therefore, P. hanleyi is considered to be a nomen dubium. 70 pp., 26 figs, gr. 8.

Zustand: New. xiv, 294, 89 col plates. 270x195mm. HB. NEW. . The first major systematic review of this unique and highly-threatened fauna to appear in nearly a century. Full colour plates of snails - the first comprehensively illustrated work on the Western Ghats land snail fauna. This region includes the western coastline of the Indian peninsula and the lowlands and foothills surrounding the main mountain range. This revision considers 337 taxa (229 species, 38 'varieties', 64 genera, 23 families). This revision evaluates and clarifies the nomenclature and taxonomy of these snails within a modern systematic framework, designating lectotypes and neotypes where appropriate, and provides colour images and specimen data of type material for all the taxa together with distributional data.

Vietnamese species from the family Plectopylidae are revised based on the type specimens of all known taxa, more than 600 historical non-type museum lots, and almost 200 newly-collected samples. Altogether more than 7000 specimens were investigated. The revision has revealed that species diversity of the Vietnamese Plectopylidae was previously overestimated. Overall, thirteen species names (anterides Gude, 1909, bavayi Gude, 1901, congesta Gude, 1898, fallax Gude, 1909, gouldingi Gude, 1909, hirsuta Möllendorff, 1901, jovia Mabille, 1887, moellendorffi Gude, 1901, persimilis Gude, 1901, pilsbryana Gude, 1901, soror Gude, 1908, tenuis Gude, 1901, verecunda Gude, 1909) were synonymised with other species. In addition to these, Gudeodiscus hemmeni sp. n. and Gudeodiscus messageri raheemi ssp. n. are described from north-western Vietnam. Sixteen species and two subspecies are recognized from Vietnam. The reproductive anatomy of eight taxa is described. Based on anatomical information, Halongella gen. n. is erected to include Plectopylis schlumbergeri and Plectopylis fruhstorferi. Additionally, the genus Gudeodiscus is subdivided into two subgenera (Gudeodiscus and Veludiscus subgen. n.) on the basis of the morphology of the reproductive anatomy and the radula. The Chinese Gudeodiscus phlyarius werneri Páll-Gergely, 2013 is moved to synonymy of Gudeodiscus phlyarius. A spermatophore was found in the organ situated next to the gametolytic sac in one specimen. This suggests that this organ in the Plectopylidae is a diverticulum. Statistically significant evidence is presented for the presence of calcareous hook-like granules inside the penis being associated with the absence of embryos in the uterus in four genera. This suggests that these probably play a role in mating periods before disappearing when embryos develop. Sicradiscus mansuyi is reported from China for the first time. 118 pp., 45 figs, gr. 8.

A Systematic Revision of the Land Snails of the Western Ghats of India is the first, major systematic review of this unique and highly-threatened fauna to appear in nearly a century. With 89 full-page colour plates of snails, it breaks new ground by being the first comprehensively-illustrated work on the Western Ghats land-snail fauna. Defining the Western Ghats as including the western coastline of the Indian peninsula and the lowlands and foothills surrounding the main mountain range, this revision considers a total of 337 taxa (299 species and 38 so-called 'varieties' belonging to 64 genera in 23 familie). These taxa are mostly snails recorded from the Western Ghats (277 species and 29 'varieties' belonging to 64 genera in 23 families), but also included are a few taxa that probably occur in this region, but have yet to be detected. The new publication evaluates and clarifies the nomenclature and taxonomy of these snails within a modern systematic framework, designating lectotypes and neotypes where appropriate, and for the first time provides colour images and specimen data of type material for all the Western Ghats taxa, alongside distributional data from the original literature. It also includes a comprehensive geo-referenced index of localities for the taxa considered. Bangkok, Thailand. Chulalongkorn University Museum of Natural History. 294 pp., 95 color plates, hardcover 4 [19.7 x 26.7 cm].

The collection of the Southeast Asian tree snail genus Amphidromus Albers, 1850 at the Natural History Museum, London includes more than 100 lots of type specimens representing 85 name-bearing types, 9 paratypes and 6 paralectotypes, and one nomen nudum. Lectotypes are here designated for A. cambojiensis, A. perakensis globosus, A. columellaris gloriosa, A. maculiferus inflata, A. lepidus, A. sinistralis lutea, A. moniliferus, A. maculiferus obscura, A. sinistralis rosea and A. sinensi vicaria. In addition, the missing types of A.A. Gould were discovered and their type status is discussed. A complete catalogue of these types, including colour photographs is provided for the first time. After examining these type specimens, two new Amphidromus species, Amphidromus (Syndromus) globonevilli Sutcharit & Panha, sp. n. and Amphidromus (Syndromus) principalis Sutcharit & Panha, sp. n. were recognized and are described herein. 57 pp., 17 figs, gr. 8.
