(Caenogastropoda, Cyclophoroidea, Diplommatinidae) from Myanmar, with a catalogue of recorded species and description of two new species. ZooKeys 1285: 71-124, DOI: 10.3897/zookeys.1285.186884
Abstract
All currently known microsnails of the genus Diplommatina s. l. from Myanmar are here listed and revised based on recently collected specimens. The specimens examined were obtained through the ‘ Conserving Myanmar’s Karst Biodiversity’ project, hosted by the Fauna & Flora International in collaboration with the Forest Department of Myanmar. In total, 31 nominal species are documented from the country. Among these, three species originally described from this region, namely D. carneola, D. scalaroidea, and D. richthofeni, were rediscovered and re-described. We also report on three new country records, D. akron, D. nimanandhi, and Pagodapalaina suratensis [formerly Diplommatina], previously known only from Thailand. In addition, two new species are described based on distinctive morphological characters: D. prolixa Tongkerd, sp. nov. from Kayin State and D. somsakpanhai Tongkerd, sp. nov. from the Tanintharyi Region. For twenty-nine taxa, we examined and illustrated name-bearing types and / or authenticated specimens whenever available, as these are critical for systematic revision. Overall, this study provides updated knowledge of the Diplommatina s. l. in Myanmar and offers a valuable foundation for future taxonomic and systematic research in Indochina. To stabilise nomenclature, D. stanisici Tongkerd, nom. nov., is herein proposed as replacement name for the Australian species Diplommatina angulata Stanisic, 2010, which is a junior primary homonym of D. angulata Theobald & Stoliczka, 1872 from Myanmar.
