Source-derived summary

The southern pig-tailed macaque (Macaca nemestrina), also known as the Sundaland pig-tailed macaque and the Sunda pig-tailed macaque, is a medium-sized macaque that lives in Sundaland, southern Thailand, Malaysia, and Indonesia. It is known locally as beruk.

Etymology and taxonomy

The species epithet, nemestrina, is an adjective (derived from Latin Nemestrinus, meaning "the god of groves") modified to agree in gender with the feminine generic name. M. nemestrina formerly included the northern pig-tailed, Pagai Island, and Siberut macaques as subspecies. All four are now considered separate species.

In the 19th century, bruh was the native name used by Malays in Sumatra for the macaque.

Description

As with other Macaca species, males are larger than females; while males are measured at 50–58 cm (20–23 in) in length and 5–12 kg (11–26 lb) in weight, females are measured at 38–48 cm (15–19 in) in length and 4.5–6 kg (9.9–13.2 lb) in weight. This macaque has buff-brown fur, with a darker dorsal area and lighter ventral area. Its common name refers to the short tail held semi-erect, resembling the tail of a pig.

Behaviour and ecology

M. nemestrina is mainly terrestrial, but also a skilled climber.

Editorial summary

This brief starts where responsible research should: with the source description of “Southern pig-tailed macaque” as species of mammal. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 193-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Southern, pig-tailed and macaque can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of mammal. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 2, 2026. The linked authority identifier is Q618026. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
