According to these studies,
Pseudophoxinus species in Anatolia, except P. fahirae,
may be grouped in 3 lineages. P. fahirae living near
Tefenni-Burdur region is different from the other
Anatolian species in having the preoperculomandibular
canal (CPM) and infraorbital canal (CIO) interconnected.
One of these 3 lineages includes P. meandri and P.
egridiri, which share, in particular, a reduced type of
cephalic sensory canal system and a reduced number of
vertebrae. Three new species belonging to this group
have been recently described (Bogutskaya et al., 2007):
P. elizavetae, P. zekayi, and P. firati.
