A common species found at 12 stations inland, previously known only from eastern Tanzania . The sculpture below the periphery is much less pronounced. Some of the shells are practically smooth basally. The shell illustrated here has a 0.69 h/w ratio. However, some other shells collected in the region are proportionally higher. An unfigured shell from station 17, for example, has similar proportions (17.0× 21.5 mm , h/ w 0.79) to the type ( h/ w 0.80). Another two similar Tanzanian species: T. usambarica Craven, 1880 and T. helicoides ( Boettger, 1913 ) do not have a sinuous lip.
