Contributions on a small collection of the former Subulinidae Fischer & Crosse, 1877 (Eupulmonata, Achatinoidea) with catalogue of the Glessula and Rishetia species recorded from Myanmar

Abstract

The taxonomy of subulinid snails in Myanmar has been evaluated, resulting in the recognition of 40 species and subspecies across nine genera: Allopeas, Bacillum, Curvella, Glessula, Opeas, Paropeas, Rishetia, Tortaxis, and Zootecus. Nine species are re-described based on recently collected specimens, and two new species, Glessula mandalayensis Man & Panha, sp. nov. from Mandalay Region and Tortaxis cylindropsis Man & Panha, sp. nov. from Shan State are introduced. The genitalia and radula of Zootecus pullus was studied for the first time. This study also presents a comprehensive list of all subulinid species recorded to date from Myanmar. The type specimens and authenticated museum specimens have been illustrated with accompanying taxonomic remarks and nine species formerly assigned in Glessula are now placed in Rishetia: R. akouktoungensis, R. baculina, R. basseinensis, R. burrailensis maxwelli, R. kentungensis, R. limborgi, R. nathiana, R. pertenuis, and R. pertenuis major.
