Eastern Berber languages

The Eastern Berber languages are a group of Berber languages spoken in Libya and Egypt. They include Awjila, Sokna and Fezzan, Siwi and Ghadamès, though it is not clear that they form a valid genealogical group.
Eastern Berber is generally considered as part of the Zenatic Berber supergroup of Northern Berber.

Classification

divides them into two groups:

one consisting of Ghadamès and Awjila. These two languages are the only Berber languages to preserve proto-Berber *β as β; elsewhere in Berber it becomes h or disappears.
the other consisting of Nafusi, Sokna and Siwi. This shares some innovations with Zenati, and others with Northern Berber in general.

Blench lists the following as separate languages, with dialects in parentheses; like Ethnologue, he classifies Nafusi as Eastern Zenati.

The "Lingvarium Project" cites two additional languages, both located in Libya: the extinct language of Jaghbub and the still-spoken Berber language of Tmessa, an oasis located in the north of the Murzuq District. Blažek considers the language spoken in Tmessa as a dialect of Fezzan.
