The treatment at Ethnologue appears to be inconsistent. ISO codes are assigned to two languages, Arandai and Kemberano, also known as Arandai. They are said to have 85% lexical similarity, which would make them dialects of one language. However, the two dialects given for Arandai, also called Kemberano and Arandai (AKA Tomu and Dombano), are said to have only 71% lexical similarity, making them different languages. Dialects of Kemberano (Weriagar) are listed as Weriagar (Kemberano) and Barau.
Additional alternative names of Arandai/Kemberano (Dombano–Tomu) are given as Jaban / Yaban, Sebyar, Sumuri. Additional alternative name of Kemberano/Arandai (Barau–Weriagar) is given as Kalitami.
Linguasphere 2010 makes a more consistent distinction:
- 20-HDA Tomu–Arandai; includes Yaban, Sebyar
- 20-HDA-a Tomu
- 20-HDA-b Arandai (Dombano)
- 20-HDB Kemberano–Barau
- 20-HDB-a Kemberano (Kalitami)
- 20-HDB-b Weriagar
- 20-HDB-c Barau
