Two land snail species of the Mekong Delta limestone hills (Cambodia, Vietnam): Aulacospira furtiva (Eupulmonata: Vertiginidae) and Georissa carinata (Neritimorpha: Hydrocenidae)

Abstract

We describe Aulacospira furtiva sp. n. (Pulmonata: Vertiginidae), and we expand on the protologue of Georissa carinata Sutcharit et Jirapatrasilp, 2020 (Neritomorpha: Hydrocenidae). Both species occur on limestone hills on the west flank of the Mekong delta, in Vietnam and Cambodia, and presumably are endemic to these hills.
