Beta Mahatvaraj (5)

Description: 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. 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). Habitat: 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. Etymology: The genus name Batasio: from the local (Bengali) name of the fish (batasio or batashi). The specific name merianiensis: –ensis, suffix denoting place: presumably a variant spelling of Mariani, referring to Mariani Junction, Assam, India, type locality.
