Relevant Information:

The specimen pictured was collected in Goalpara District, Assam, India. Batasio species are small, laterally compressed bagrid catfishes generally found in fast-flowing hill streams throughout South Asia, Myanmar, the Salween and Mae Khlong drainages of Thailand and the northern Malay Peninsula. 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. Differs from B. affinis in having a shorter adipose fin 4.5 in standard length versus 2.9; shorter head, longer maxillary barbels and shorter head, longer maxillary barbels and snout and a smooth dorsal spine.
