According to Blench (2006) there are two sub-dialects: Shingani and Lower Shebelle.[1] As noted in recent work on the speech variety, Green & Jones (2016)[2]:
"What we hope to have illustrated in this talk is that while Marka (Af Ashraaf) may be similar in certain ways to both Northern Somali and Maay, it nonetheless boasts a number of unique properties, particularly in its morphology, that we believe merit its treatment not as a Somali or Maay dialect, but as a language variety of its own"
A similar level of skepticism towards the labelling of other Omo-Tana languages in Somalia (such as Maay, Dabarre, Jiddu) is expressed in Tosco (2012)[3]:
Tosco's model for classifying Omo-Tana, acknowledging both the sociolinguistic situation of Cushitic languages in Somalia labeled as "dialects" of Somali and their actual classification as languages apart from Somali
"It is well-known that the term 'dialects' may refer to different 'things'. Within Somalia, it is safe to say that all the Somali dialects are 'dialects' from a sociolinguistic point of view, that is, in terms of their social role, their general absence in written media, and the speakers' acceptance of Northern-Central Somali as a common medium. From a strictly linguistic point of view, however, mutual comprehension should be assessed and dialects labelled accordingly (as mutually understandable varieties of a language). No classification so far does that."
