Abstract

Aulacospira depressus n. sp. and A. khaobote n. sp. (Pulmonata: Pupillidae: Gastrocoptinae) are described from limestone hills, Rayong and Srakeo Provinces, Thailand. This is the third report in total 6 species of this genus occurring in Thailand. Both species have the prominent sulci on the last two whorls. Shell narrowly umbilicated with incised sutures, slightly deflected tubas without apertural barrier. The shell of A. depressus is highly depressed. A broad distinct spiral sulcus above the extended peripheral angel begins from the penultimate whorl continuously to the apertural edge. The shell of A. khaobote is helicoid and has rounded whorls. The broad sulcus is distinct located continuously from penultimate whorl to apertural edge.
