Remarks.

This species has previously been synonymised with Sulcospira schmidti (Martens, 1908), which was also originally described from Borneo ( Köhler and Glaubrecht 2001). Shells appear to be highly plastic, with material examined having shells with rounded or pointed basal lips, with or without raised ribs, and with or without spiral striae at the bottom of final body whorl. Other species of Sulcospira have previously been described from Borneo (see e.g., Köhler and Glaubrecht 2001, 2002, Köhler and Dames 2009), but pending further analysis and availability of fresh material for molecular sequencing, we tentatively consider all material conspecific.
