Trochomorpha sp. 3.

Material examined.

Specimens from Par-Houak limestone, Ban Vieng Swang village, Vieng Phoukha District, Luang Namtha Province (Fig. 34A).

Remarks.

These specimens are similar to Trochomorpha bicolor Martens, 1864, but the distinct characters are an elevated conical shell with flattening below the periphery, and a narrower and deep umbilicus.

The generic assignment of this species in Trochomorpha s.l. is still provisional, and additional anatomical studies are necessary to confirm the systematic position of this species.
