Nematabramis

Nematabramis alestes is a cyprinid from the southern Philippines, with records from Basilan, Mindanao, Palawan and Busuanga. The only member of the genus with barbels shorter than the head, its body has a pronounced ventral keel.

Nematabramis borneensis is a cyprinid endemic to the Malaysian state of Sabah in northern Borneo. It looks particularly similar to N. alestes, sharing a dark lateral stripe, but is told apart immediately by its barbels, which are longer than the head.

Nematabramis everetti is a cyprinid endemic to Borneo, known from Sarawak and Sabah plus East and North Kalimantan. It has a distinctive dark, vertically-elongate humeral marking, more prominent than in other Nematabramis species. Juveniles and subadults appear to favour fast-moving water, while adults are found in deeper, slower stretches of minor tributaries.

Nematabramis steindachnerii is a cyprinid endemic to northern and central Borneo, in Sarawak, Sabah, Brunei and North and East Kalimantan. It has barbels longer than the head but not reaching beyond the pectoral-fin base, and a relatively slender body with a short head.
