In Omotic languages especially it is expected that the five phonemic vowels will each have long counterparts.
I presented evidence of a twenty-three consonant phoneme system, including a three way voiced-ejective-voiceless contrast in the oral stops and sibilants--a well attested feature of Omotic languages. Also included was evidence of a nasalizing glottal phoneme /?/, which causes unmotivated (phonemic) nasality on preceding and following vowels and contrasts word medially with the oral glottal stop /?/.

Many other Omotic languages also lack [r] in the initial position, such as Sheko, Dizin, Bench ("Gimira", see Haywad 1990:1-67), as well as the neighbouring Nilo-Saharan language Gwama.
Originally it was used to refer to the language now known as Anfillo [myo], then classified as a Koman language of the Nilo-Saharan phylum but now determined to be an Omotic language of the Kefoid sub-group (Bender 2000:179).

In the eastern part of the survey area we find the Omotic languages Seze and Hozo (32), while the related Northern Mao is spoken around Bambasi north of our survey area and in the Didessa valley.
called Mao is spoken in the Begi and Ton-go areas (different from the Mao of Bambasi which belongs to a Mao group of Omotic languages [...].
Ahland, (2012:15f) refers to Bender (2003) who suggests a 2-way split from Proto-Omotic into Mao and all other Omotic languages72, and to Hayward (2000) who classifies the Mao languages as one member of a 3-way split from Proto-Omotic into Mao, South Omotic and North Omotic.73 Ahland further refers to Bender (2000) who states that the Mao languages are the most divergent in Omotic and supports a 2-way split solution lumping Omotic Mao in one group and all other Omotic languages in another branch.
This survey has no intention of interfering with the discussion about the internal classification of the Omotic languages. It merely intends to suggest the use of terms that are as clear and unambiguous as possible.
(2) Seze, Hozo, Northern Mao and Ganza are Omotic languages and may be called Omotic Mao.
This is regardless of whether Omotic Mao is classified as an independent second or third branch of the Omotic languages (Bender 2003; Hayward 2000) or as a branch of the North Omotic languages.
