Distribution
The distribution of Pachydrobiella brevis includes Khong Island in the Mekong River, southern Laos.[1] The type locality is Khong Island.[1] This species is probably endemic to the Khong Island region.[1]
Description
The shape of the shell is ovate-conic.[1] The shell is thick and smooth.[1] The smooth shell is unique in the tribe Jullieniini.[1] The outer lip is thick with growth lines.[1]
The width of the shell is 2.5 mm.[3] The height of the shell is 2.2–3.6 mm.[1]
Thiele (1928)[2] and Brandt (1970) made a drawing showing smooth teeth in the radula, but Davis (1979) showed multiserrate teeth in the radula.[1]
Ecology
Pachydrobiella brevis lives primarily in freshwater habitats that lack a current or have only a slight current.[1] However this species sometimes or rarely also lives also in places where the current is moderate or strong all the way to whitewater.[1]
