Leptobarbus hosii, the Sayan Barb, also locally called as Piam and Temopong, is a species of ray-finned fish in the genus Leptobarbus from freshwater habitats in northern Borneo in southeast Asia. However, a previously unknown population has been recorded in West Kalimantan. ^[2]

Named in honor of Charles Hose (1863–1929), British colonial administrator in Borneo, zoologist and ethnologist, who collected the type specimen. ^[3]

Description

Little is known of the species except for its appearance. ^[4] The fins are red to maroon, while near the gill plate and above the pelvic fin there is a black vertical spot. It does not have a black lateral line running along its body, unlike L. melanotaenia and L. rubripinna.

Maxing out at 8.5 cm, ^[5] it is possibly the smallest member of its genus.
