The Philippine long-tailed macaque (M. f. philippensis) is listed as near threatened
This is outdated/incorrect taxonomy and status. IUCN says *M. f. philippinensis* is under dispute, and it has been tentatively removed as a separate Red List assessment and included with *M. f. fascicularis*.
Full reasoning
This statement is incorrect for two reasons.
- The name used here is not the accepted subspecies name. Standard references list the Philippine taxon as Macaca fascicularis philippinensis, not philippensis.
- IUCN does not currently treat it as a separately assessed Near Threatened subspecies. In the 2022 IUCN Red List assessment for Macaca fascicularis, the assessors state that M. f. philippinensis is under dispute and has been tentatively removed from Red List assessment, being included with M. f. fascicularis instead. The same assessment also lists “Macaca fascicularis ssp. philippensis (discarded)” among infra-specific taxa.
So the article is wrong to say that “M. f. philippensis” is a subspecies currently listed as Near Threatened.

- The IUCN Red List of Threatened Species: Macaca fascicularis (amended version of 2022 assessment)
Infra-specific Taxa Assessed: ... • Macaca fascicularis ssp. philippensis (discarded) ... The most eastern subspecies, M. f. philippinensis has come under dispute. Consequently, it has been tentatively removed from Red List assessment and is currently included with M. f. fascicularis.
- Primate Factsheets: Long-tailed macaque (Macaca fascicularis)
Subspecies: ... M. f. philippinensis ...
M. f. condorensis is vulnerable. All other subspecies are listed as data deficient and need further study
These Red List statuses are wrong. In the 2022 IUCN updates, *M. f. condorensis* was listed as Endangered, while several other subspecies were assessed as Vulnerable or Critically Endangered rather than Data Deficient.
Full reasoning
This sentence no longer matches the 2022 IUCN Red List subspecies assessments.
A 2022 summary table of the IUCN updates for Macaca fascicularis subspecies shows:
- M. f. condorensis: Endangered (EN), not Vulnerable.
- M. f. aurea: Vulnerable (VU).
- M. f. atriceps: Vulnerable (VU).
- M. f. fusca: Critically Endangered (CR).
- M. f. karimondjawae: Critically Endangered (CR).
- M. f. lasiae: Critically Endangered (CR).
- M. f. tua: Critically Endangered (CR).
- M. f. umbrosa: Vulnerable (VU).
So it is incorrect to say “All other subspecies are listed as data deficient.” A recent 2026 paper likewise refers to M. f. fusca, M. f. lasiae, M. f. tua, and M. f. karimondjawae as already having Critically Endangered status.

Table 1 lists 2022 categories as: Macaca fascicularis aurea — VU; M. f. atriceps — VU; M. f. condorensis — EN; M. f. fusca — CR; M. f. karimondjawae — CR; M. f. lasiae — CR; M. f. tua — CR; M. f. umbrosa — VU.
- Distribution and conservation status of four endemic long-tailed macaque subspecies in Indonesia
Population data for island-endemic subspecies of the long-tailed macaque remain scarce despite their Critically Endangered status... on Macaca fascicularis fusca, M. f. lasiae, M. f. tua, and M. f. karimondjawae.
