Proboscis monkey
species of mammal
The proboscis monkey or long-nosed monkey (Nasalis larvatus) is an arboreal Old World monkey with an unusually large nose (or proboscis), a reddish-brown skin color and a long tail. It is endemic to the Southeast Asian island of Borneo and is found mostly in mangrove forests and on the coastal areas of the island.
This species co-exists with the Bornean orangutan and monkeys such as the silvery lutung. It belongs in the monotypic genus Nasalis.
Taxonomy
The proboscis monkey belongs to the subfamily Colobinae of the Old World monkeys. The two subspecies are:
N. l. larvatus (Wurmb, 1787), which occupies the whole range of the species excluding northeast Kalimantan
N. l. orientalis (Chasen, 1940), restricted to north-east Kalimantan
However, the difference between the subspecies is small, and not all authorities recognise N. l. orientalis.
The genus name Nasalis comes from the Latin word nasus meaning "nose".
Begin with the source’s own compact description: “Proboscis monkey” is species of mammal. The dossier treats that line as a proposition to test through Proboscis, monkey and species, not as a finished interpretation.
Why this record matters
The phrase “species of mammal” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q192029. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1787 and 1940.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
