Lectotypes are here designated for Amphidromuscambojiensis, Amphidromusperakensisglobosus, Amphidromuscolumellarisgloriosa, Amphidromusmaculiferusinflata, Amphidromuslepidus, Amphidromussinistralislutea, Amphidromusmoniliferus, Amphidromusmaculiferusobscura, Amphidromussinistralisrosea and Amphidromussinensivicaria. In addition, the missing types of A.A. Gould were discovered and their type status is discussed. A complete catalogue of these types, including colour photographs is provided for the first time. After examining these type specimens, two new Amphidromus species, Amphidromus (Syndromus) globonevilli Sutcharit & Panha, sp. n. and Amphidromus (Syndromus) principalis Sutcharit & Panha, sp. n. were recognized and are described herein.
