The microsnail genera <i>Clostophis</i> and <i>Acinolaemus</i> (Eupulmonata, Pupilloidea, Hypselostomatidae) from central Thailand, with description of three new species.

ABSTRACT: Hypselostomatid microsnails of the genera Clostophis and Acinolaemus from limestone hills in central Thailand were studied and three new species are described. Clostophis rhynchotes Tongkerd & Panha, sp. nov. is diagnosed by a conical spire, long and descending tuba, 14 spiral striations on the last whorl, and only a single parietal lamella. In addition, a previously known species, C. proboscideus, is redescribed, and variations in its apertural dentition are also documented. In the genus Acinolaemus, two new sympatric species that clearly differ in shell shape are described. Acinolaemus rhamphodontis Tongkerd & Panha, sp. nov. is characterised by a depressed conical spire with a long and descending tuba, and eight apertural dentition
