Ethnologue

Ethnologue 26 lists the following languages of South America as unclassified:

• Awishira (Peru)
• Agavotaguerra (Brazil – unattested, apparently a dialect of Yawalapití)
• Aguano (Peru)
• Carabayo (Colombia)
• Himarimã (Brazil)
• Kaimbé (Brazil)
• Kambiwá (Brazil)
• Kapinawá (Brazil)
• Lule (Argentina)
• Mato Grosso Arára (Brazil)
• Pankararé (Brazil)
• Pijao (Colombia)
• Pumé (Yaruro, Venezuela)
• Shenenawa (Brazil)
• Tingui-Boto (Brazil)
• Tremembé (Brazil)
• Truká (Brazil)
• Wakoná (Brazil)
• Wasu (Brazil)

However, Glottolog states that Agavotaguerra is not unclassified, but unattested; the only reports are that the Agavotaguerra speak Yawalapiti.

In addition, Ethnologue classifies Aikanã, Uamué and Xukurú, all of Brazil as isolates, but they are too poorly attested to classify.
