Scale represent 5 mm. Diagnosis. Shell very small, sinistral, brownish, with moderately wide umbilicus, almost flat dorsal surface (only the apex is elevated slightly), and rounded body whorl; callus strong, palatal plicae long, more or less straight horizontal, with dichotomously divided posterior ends and many small denticles at their posterior ends; lamella single, curved, in contact with a lower plica, which runs until the peristome. Measurements (in mm): D: 9.1, H: 4.9 (n = 1, type series). Differential diagnosis. Endothyrella bedfordi has a single curved parietal lamella with a long lower plica (which reaches the peristome) attached to it, and at the posterior ends of palatal plicae there are several small denticles. These features distinguish Endothyrella bedfordi from all congeners. See also Table 5. Distribution. The species is known from the type locality only (approximately 28°44'N , 94°56'E ) (Figure 10).
