Two new species of Clausiliidae (Gastropoda: Pulmonata) from Yunnan Province, southern China

Abstract

Formosana renzhigangi n. sp. and Serriphaedusa (Gibbophaedusa) gerberi n. sp. are described from Yunnan Province of southern China. Additionally, new occurrence records of Papilliphaedusa kunmingensis (Chen et Zhang, 1999) are provided. The composition and diversity of Yunnan's Clausiliidae fauna, its relation to those of the adjacent zoogeographic regions, and the taxonomic status of the native genera Formosana Boettger, 1877 and Papilliphaedusa Nordsieck, 2003 are discussed.

Two new Tropidauchenia species (Gastropoda: Clausiliidae: Garnieriinae) from Guangxi, China

“…Two new species of Tropidauchenia from Chongzuo, Western Guangxi, are described and illustrated here based on shell characters. T. sulcicollis Grego et Szekeres, 2017, the closest relative of the two new species, is re-described. Re-description (based on the new material).…”

“…Guangxi has a typical karstic topography, providing suitable habitats for numerous Clausiliidae, especially for the Garnieriinae. Approximately 83% of the Chinese garnieriine species have been recorded from Guangxi (NordsiecK 2012, 2016, GreGo & szeKeres 2017. Two genera of this subfamily are found in Guangxi, viz., Tropidauchenia and Grandinenia.…”

“…The shell nomenclature follows NordsiecK (2007) and partlyGreGo & szeKeres (2017). The studied specimens will be deposited at Mianyang Normal University, Sichuan, China (MYNU).…”

Within‐island diversification in the land snail genus Formosana (Gastropoda, Clausiliidae) in Taiwan

“…Formosana contains 37 species and is distributed in Taiwan, northern Vietnam, and southwestern China (Grego & Szekeres, 2011; Grego & Szekeres, 2017; Grego & Szekeres, 2019; Grego et al, 2014; Hunyadi & Szekeres, 2016; MolluscaBase, accessed, 2022; Nordsieck, 2007). According to recent checklists (Hsieh et al, 2013; Nordsieck, 2007), Taiwan harbours seven nominal species (Table 1) including the type species Clausilia swinhoei Pfeiffer, 1865.…”

A new species and new genus of Clausiliidae (Gastropoda: Stylommatophora) from south-eastern Hubei, China

“…In the past decades, quite a few authors have conducted research on the systematics of the Chinese Clausiliidae. Their research hotspots were mostly located in southern China, namely the provinces Sichuan, Chongqing, Guizhou, Yunnan, Guangxi and parts of Guangdong and Hubei, which have a rich malacofauna (gregO & sZeKeres 2011, 2017, 2019, 2020, hunYadi & sZeKeres 2016, nOrdsieCK 2001, 2003, 2005, 2006, 2007, 2012a. Other regions have been less intensively explored for the Clausiliidae.…”
