Maxakalían languages
The Maxakalían languages (also Mashakalían) were first classified into the Jê languages. It was only in 1931 that Čestmír Loukotka separated them from the Jê family. Alfred Métraux and Curt Nimuendajú considered the Maxakalían family isolated from others. John Alden Mason suggests a connection with the Macro-Jê stock, confirmed by Aryon Rodrigues. Languages
Apart from extinct varieties generally seen as dialects of Maxakalí, Mason noted resemblances with a few other extinct languages of the area: Pataxó, Malalí and Coropó. However, Coropó is now thought to be a Purian language. Campbell (1997) therefore lists the Maxakalian languages as:

 Malalí (†)
 Pataxó (Patashó) (†) (retain some words)
 Maxakalí (Mashacalí) (1,270 speakers)

Glottolog (2016) restores Coropó (Koropó) as a Maxakalían language. Nikulin (2020)
Nikulin (2020) proposes the following internal classification of the Maxakalían languages:

Maxakalí
Malalí
Nuclear Maxakalí
Maxakalí
Ritual Maxakalí; Makoní
Pataxó; Pataxó-Hãhãhãe
Koropó

Maxakalí is a sister of Krenák and possibly also Kamakã. Together, they form a Trans-São Francisco branch within the Macro-Jê language phylum in Nikulin's (2020) classification. Ramirez (2015)
Internal classification of the Maxakali languages according to Ramirez, et al. (2015):

Malali
Maxakali-Pataxó
(?) Koropó
Maxakali proper
Maxakali
Old Machacari (including: Monoxó, Makoni, Kapoxó, Kumanaxó, Panhame, etc.) Pataxó of Wied
Pataxó-Hãhãhãe

Currently, Maxakali (excluding Old Machacari) is the only living language, while all other languages are extinct. Pataxó as documented by Prince Maximilian of Wied-Neuwied (1989: 510–511) in 1816 is distinct from Pataxó-Hãhãhãe. Pataxó-Hãhãhãe was spoken into the 20th century and has been documented by Meader (1978: 45–50), Loukotka (1963: 32–33), and Silva & Rodrigues (1982). Many Maxakalian varieties are attested only from 19th-century word lists, some of which are:
Mashacari (A.St-Hil, 2000: 274; Wied, 1989: 509–510) [collected in 1816–1817]
Kapoxó (Martius, 1863: 170–172) [collected in 1818]
Monoxó (Saint-Hilaire, 2000: 181) [collected in 1817]
Makoni (Saint-Hilaire, 2000: 212; Martius, 1863: 173–176; Wied, 1989: 512–513) [collected in 1816–1818]
Malali (Saint-Hilaire, 2000: 181; Martius, 1863: 207–208; Wied, 1989: 511–512) [collected in 1816–1818]
