Title

Siamochlamys panhai, a new limestone karst-restricted terrestrial snail from Thailand (Eupulmonata: Helicarionidae)

Abstract

A new genus and new species of helicarionid snail, Siamochlamys panhai, is described from limestone outcrops in Thailand. This new genus differs from all helicarionid genera based on morphological characters of shell, radula, and genitalia. The diagnostic characters of Siamochlamys panhai gen. et sp. nov. are depressed shell, well-polished surface, umbilicus opened, and aperture less covered by reflection of columellar margin. The genitalia exhibit a straight epiphallic caecum and small flagellum but lack a dart apparatus; radula has tricuspid central and lateral teeth and bicuspid marginal teeth. The discovery of this karst-associated land snail increases the knowledge of endemic malacofauna in Thailand, and also suggests that many taxa remain undiscovered.
