Dizi differs from the rest of the two languages somewhat more (Aklilu 2003), although Glottolog considers similarities between Sheko and Nayi to be due to retentions rather than evidence of subgrouping.
Güldemann (2018) accepts that Dizoid is more likely to be related to Ta-Ne ("North Omotic") than Mao and Aroid are, and observes loanword influence on Maji languages from the Gimira subgroup of Ta-Ne.[2]
