brown with 4 vertical dark brown bars. They are diagnosed
(together with Chandramara) from other members
of the Bagridae in possessing large sensory pores
on the head, a narrow mental region, the transversely
elongated, bar-like entopterygoid, and the close contact
of the metapterygoid with the quadrate (Mo, 1991).
Batasio is distinguished from Chandramara
by the absence (vs. presence) of a pair of prominent
posterior processes on the anterior part of the vomer.
