Taxon classification Animalia Stylommatophora Camaenidae

Genus Trachia Albers, 1860

Trachia Albers in Albers & Von Martens, 1860: 160.

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.
