The Tropical micro-landsnail of the genus Plectostoma exhibits a greater diversity in shell forms, largely due to the last whorl, which, in some species is coiled irregularly. The genus counts 79 species and occurs in Vietnam, Thailand, Peninsular Malaysia, Sumatra, and Borneo. Plectostoma can only be found in limestone outcrops, where the rock face is its major habitat. This work revises non-Borneo Plectostoma species, which are more diverse in their shell form than Bornean Plectostoma. As a result, 10 new Plectostoma species are described together with the existing 21 species, based on the redefined shell characters and genetic data. In addition, all the data of 31 species, namely, 62 references, 214 collections, 290 pictures, and 155 3D models, were simultaneously tagged and linked to each other. All the synthesised, semantic-tagged, and linked taxonomic information is made freely and publicly available online.
