Sewellia
''Sewellia'' is a genus of fish in the family Balitoridae (River Loaches) found in Laos and Vietnam.Kottelat, M. (2012)Conspectus cobitidum: an inventory of the loaches of the world (Teleostei: Cypriniformes: Cobitoidei). ''Raffles Bulletin of Zoology, Suppl. No. 26: 1-199.'' According to Roberts (1998) a possible defining characteristic of the genus ''Sewellia'' is their posterior pelvic valve is highly complex and different from other rheophilic loaches (loaches adapted to fast flowing water), their posterior pelvic valve involves the overlapping of the second to last ventrally exposed rays. Adapted to high velocity streams ''Sewellia'' have depressed body shapes that are laterally expanded thus increasing their hydrodynamical properties and allowing them to better stay attached to rocks in swift current. ''Sewellia'' also have paired fins with a single simple ray and numerous branched rays allowing them to grip rocks in swift current. Distribution Fish in the genus ''Sewelli ...
