<i>Batasio eugenius</i> , a new catfish from the <scp>Irrawaddy River</scp> drainage ( <scp>Siluriformes: Bagridae</scp> )

This study describes a new species of bagrid catfish, Batasio eugenius, from the upper Irrawaddy River drainage in Myanmar. Batasio eugenius is chiefly diagnosed from congeners by its short snout (32-33% head length [HL]), large eye (29-33% HL), very long nasal barbel reaching beyond posterior orbital margin and short adipose-fin base of about 13% standard length, in addition to a suite of other morphological characters. The taxonomic status of B. flavus is discussed and evidence is presented here to show that B. flavus is conspecific with B. travancoria.
