species of mammal

The black-fronted titi monkey (Callicebus nigrifrons) is a species of titi, a type of New World monkey.
The black-fronted titi is a small diurnal primate. The body of this primate is covered in grey to brown fur with black fur concentrated around the face, the tail is slightly orange in color. Body weight ranges from 1–2 kilograms (2.2–4.4 lb) and the head-body length is around 270–450 millimeters (11–18 in). This species does not exhibit sexual dimorphism. Members of this species can live up to 12 years of age in captivity.
Habitat and distribution
The black-fronted titi is endemic to the Atlantic forest region of Brazil and has a home range averaging 20 hectares (49 acres). The black-fronted titi is arboreal and prefers the middle to upper canopy of the forest. However, it will move to the forest floor at times to forage, travel, and play. Play behavior on the forest floor has been documented between black-fronted titis and marmosets in Brazil.

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.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 30, 2026. The linked authority identifier is Q1350681. None of the 0 selected statements returned an explicit reference.
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.
