Bagrichthys obscurus, a new species of bagrid catfish from Indochina (Teleostei: Bagridae)
Abstract
Bagrichthys obscurus new species, is described from drainages in Indochina. It is morphologically similar to and has been previously identified as B. macropterus, but can be differentiated from that species in having a uniformly brown body without a pale midlateral stripe and without pale blotches on the sides of the body, a more slender body, a shorter adipose-fin base, and the genital papilla in males meeting the base of the first anal-fin ray.
