William Charles Linnaeus Martin (1798–1864) published the name Semnopithecus (now Presbytis) femoralis
based on several specimens at the Natural History Museum in London. One of these specimens was collected by Raffles from Singapore. Today known commonly as Raffles’s banded langur, this species was the first primate from Singapore to be given a scientific name. An illustration
of this monkey, possibly based on a taxidermised specimen, was published in the Zoological Researches of Java
and appeared in July 1822. This drawing lacks the diagnostic white fur on the chest and on the inside of its thighs.
The local context:
The species is endemic to Singapore and southern Peninsular Malaysia, and nearly went extinct in Singapore. Today, a population of about 60 to 70 individuals can be found in the central forests of the island. It remains critically endangered throughout its range.
