Additions to the knowledge of the land snails of Sabah (Malaysia, Borneo), including 48 new species Author Vermeulen, Jaap J.

Remarks. The classification of this genus is still unresolved ( Solem 1964 ). We include the species below on account of the similarity of its shell to that of Trachia pudica Godwin Austen, 1891, a species native to Sabah. With its drawn-out peristome it would also fit in Planispira Beck, 1838, but all species included in this genus have an open umbilicus.
