The system of "Eastern Plectopylidae" (China, Vietnam, Taiwan and Japan) is revised (excl. Amphicoelina). Three genera are recognised: Gudeodiscus n. gen. Sicradiscus n. gen. and Sinicola Gude 1899. From Vietnam a new subspecies, Gudeodiscus emigrans quadrilamellatus n. ssp. is described. From China, 46 taxa (including 3 doubtful) are recognised and the following new species and subspecies are described as new to science: G. concavus n. sp., G. emigrans otanii n. ssp., G. eroessi n. sp., G. eroessi fuscus n. ssp., G. eroessi hemisculptus n. ssp., G. giardi oharai n. ssp., G. giardi szekeresi n. ssp., G. goliath n. sp., G. okuboi n. sp., G. phlyarius werneri n. ssp., G. pulvinaris robustus n. ssp., G. soosi n. sp., G. ursula n. sp., G. yanghaoi n. sp., G. yunnanensis n. sp., Sicradiscus feheri n. sp., Sic. transitus n. sp., Sinicola asamiana n. sp., Sin. schmackeri n. sp., Sin. stenomphala n. sp. The systematic position of two non-Chinese species (from Arunachal Pradesh, India) assigned to the genera Sinicola and Endoplon respectively, is discussed; Plectopylis (Endoplon) aborensis and Plectopylis (Sinicola) babbagei both belong to Endothyrella.©2013 E.

A middle-sized pupinid species was recently discovered in Vietnam and described here as Rhaphaulus tonkinensis n. sp. Its shell is characterized by a thick, rather flat outer tube which turns downwards along the peristome margin. This new species represents the first record of the species from Vietnam. A checklist of Rhaphaulus and Streptaulus taxa, photos of most known species (mainly type specimens) and a comprehensive map are presented. The taxonomic position of the genus Streptaulus is discussed. Source

Seven new species of Hypselostomatidae are described from the Chinese province Guangxi: Angustopila dominikae Páll-Gergely & Hunyadi, sp. n., A. fabella Páll-Gergely & Hunyadi, sp. n., A. subelevata Páll- Gergely & Hunyadi, sp. n., A. szekeresi Páll-Gergely & Hunyadi, sp. n., Hypselostoma socialis Páll-Gergely & Hunyadi, sp. n., H. lacrima Páll-Gergely & Hunyadi, sp. n. and Krobylos sinensis Páll-Gergely & Hunyadi, sp. n. The latter species is reported from three localities. All other new species are known only from the type locality. Specimens nearly identical to the type specimens of Angustopila huoyani Jochum, Slapnik & Páll-Gergely, 2014 were found in a cave in northern Guangxi, 500 km from the type locality. Adult individuals of Angustopila subelevata sp. n. (shell height = 0.83–0.91 mm, mean = 0.87 mm) and A. dominikae sp. n. (shell height of the holotype = 0.86 mm) represent the smallest known members of the Hypselostomatidae, and thus are amongst the smallest land snails ever reported. We note that Pyramidula laosensis Saurin, 1953 might also belong to Krobylos. Paraboysidia neglecta van Benthem Jutting, 1961, which was previously included in Angustopila, is classified in Hypselostoma. © Barna Páll-Gergely et al. Source

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 G. 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 P. 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 G. phlyarius werneri Páll-Gergely, 2013 is moved to synonymy of G. 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. © Barna Páll-Gergely. Source

The present paper revises all species that have been assigned to Pseudopomatias Möllendorff, 1885 and Nodopomatias Gude, 1921. The following new species are described: Pseudopomatias abletti Páll-Gergely, n. sp. (northeastern India), Pseudopomatias harli Páll-Gergely, n. sp. (northeastern India), Pseudopomatias linanprietoae Páll-Gergely n. sp. (Laos), Pseudopomatias maasseni Páll-Gergely & Hunyadi, n. sp. (Vietnam and China), Pseudopomatias nitens Páll-Gergely n. sp. (Vietnam), Pseudopomatias prestoni Páll-Gergely, n. sp. (northeastern India), Pseudopomatias reischuetzi Páll-Gergely, n. sp. (north-eastern India), Pseudopomatias shanensis Páll-Gergely n. sp. (Myanmar) and Pseudopomatias sophiae Páll-Gergely, n. sp. (Vietnam). Pseudopomatias fulvus is moved to the synonymy of P. amoenus. Csomapupa n. gen. is erected for Pseudopomatias grandis and P. luyorensis. Another new genus, Vargapupa is erected with two species, namely Vargapupa biheli Páll-Gergely, n. sp. (Vietnam) and V. oharai Páll-Gergely, n. sp. (Laos). Both new genera are probably closely related to Pseudopomatias and Nodopomatias. All the currently available type specimens of species in these groups are figured. Anatomical information of P. eos and DNA sequence data of two Pseudopomatias species indicate that the genus is a member of the family Pupinidae. The other pre-existing hypothesis, namely that Pseudopomatias is a member of the Cochlostomatidae, is not supported by our results. © 2015 Magnolia Press. Source
