Schistura kaysonei, n. sp. is the first troglobitic nemacheiline fish discovered in the Laos PDR. It is distinguished by elongated nasal flaps, and by the absence of external eyes and colour pattern in adults. Juveniles or sub-adults have dark pigment on the dorsum when exposed to light in captivity. The new species was obtained some 600 m from the entrance of the Phu Tham Nam cave in the Khammouan karst formation.
