Source-derived summary

The Rikbaktsa are an Indigenous group from the Mato Grosso region of Brazil.

Name

Rikbaktsa (Rikbaktsa rik, person + bak, human being + tsa [plural suffix]), the group's self-denomination, can be translated as "the human beings". Variant spellings include Ricbacta, Erikbaktsa, Erigpaktsa, Erigpagtsá, Erigpactsa, Erikbaktsá, Arikpaktsá, and Aripaktsá. Locally, they are also called Canoeiros (Canoe People), alluding to their aptitude in canoe use, or—more rarely—Orelhas de Pau (Wooden Ears), alluding to their practice of enlarging their earlobes with wooden plugs.

Location

The Rikbaktsa live in the Amazon rain forest of northwest Mato Grosso. Their traditional territory spanned 50,000 km² of Juruena River basin, stretching from the Papagaio River in the south to the Augusto Falls on the upper Tapajós River in the north. Their territory was bounded on the west by the Aripuanã River and on the east by the Arinos River, near the Peixes River.

Today, they have rights to three Indigenous Lands: Erikbaktsa (79,935 hectares, demarcated in 1968), Japuíra (152,509 hectares, demarcated in 1986), and Escondido (168,938 hectares, demarcated in 1998).

History

There are no pre-20th century historical references to the Rikbaktsa, and there have been no archeological studies to date their occupation of their traditional lands. However, oral histories, geographic references in their myths, and their detailed knowledge of nearby flora and fauna suggest that they have lived on the land for some time.

Editorial analysis

Why this record matters

“Rikbaktsa” is worth following because a concise public description often conceals a longer documentary argument. Here, Rikbaktsa, ethnic and group provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 22, 2026. The linked authority identifier is Q202511. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1968, 1986 and 1998.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
