The banded surili (Presbytis femoralis), also known as the banded leaf monkey or banded langur, is a species of primate in the family Cercopithecidae. It is endemic to the Thai-Malay Peninsula and the Indonesia island of Sumatra. It is threatened by habitat loss.
Three subspecies, femoralis (nominate), robinsoni and percura, are currently recognized, but the taxonomy is complex and disputed, and it has also included P. natunae, P. siamensis and P. chrysomelas as subspecies, or alternatively all these (including P. femoralis) have been considered subspecies of P. melalophos. It is diurnal and eats fruit. Of the subspecies currently recognized, P. f. femoralis lives in Singapore and Johor in the southern Malay Peninsula, P. f. robinsoni lives in the northern Malay Peninsula, including southern Burma and Thailand, and P. f. percura lives in east-central Sumatra.
In the past, some scientists, such as Oates, Davies and Delson (1994), regarded P. femoralis as a subspecies of the Sumatran surili (Presbytis melalophos). Until 1984, the white-thighed surili (Presbytis siamensis) was considered a subspecies of the banded surili. This would have covered the Natuna Island surili (Presbytis natunae), which was only deemed to be separate from the white-thighed surili in 2001. The white-thighed surili has a range in Malaysia between the ranges of P. f. femoralis and P. f. robinsoni. In Thailand, individual white-thighed suurilis are sometimes found within the range of P. f. robinsoni. A 2010 genetic study by Vun, et al. suggested that P. f. robinsoni may be more closely related to the white-thighed surili than to P. f. femoralis.
