Akysis pulvinatus is a species of stream catfish.

It is known only from the western half of the Kra Isthmus (i.e. in streams flowing into the Andaman Sea), in southern Thailand.

[1][3] This is a small catfish, where none of the type specimens exceeding 30 mm standard length.

it is brown with yellowish patches but can be distinguished from its congeners by a combination of characters including a yellowish snout, an adipose fin with a long base, a relatively deep caudal peduncle and a forked caudal fin with the lower lobe longer than the upper.

[2] Not much is known about this species including the population, threats and conservation actions, except that it may be caught as a bycatch in artisanal fisheries.
