Fang, Fang
The three barredDanio species known from the Irrawaddy River drainage are redescribed. Two species are known from southwestern Yunnan:Danio interruptus in the Husa He and Longchuan, Jian watersheds, andD. apogon abundantly in the main river and tributaries of the Daying Jiang basin. The third species,D. shanensis, occurs in the Myitnge basin of northern Shan State, Myanmar.Danio interruptus differs from other barredDanio species by having a short, incomplete lateral line, a deeper head, and shorter thicker dark vertical bars or blotches anteriorly on the sides.Danio shanensis has the lateral line either complete or incomplete, lesser head depth, and a series of deeper narrower vertical bars.Danio apogon has no lateral line, narrow or indistinct dark vertical bars, and a wide, but indistinct, horizonatal P stripe.Danio choprae, previously considered, as a barredDanio species, is more closely related to theD. dangila species group.
