Description d'un nouveau Danio

Description of Danio flagrans, and redescription of D. choprae, two closely related species from the Ayeyarwaddy River drainage in northern Myanmar (Teleostei: Cyprinidae)

par Sven O. Kullander

Danio flagrans, new species, is described from headwaters of the Mali Hka River in the vicinity of Putao in north- ern Myanmar. It is distinguished from D. choprae by longer barbels, longer caudal peduncle, shorter anal-fin base, more caudal vertebrae, fewer anal-fin rays, short vs. usually absent lateral line, details of the colour pattern, and mitochondrial DNA sequences. The two species share a unique colour pattern combining dark vertical bars an- teriorly on the side with dark horizontal stripes postabdominally, and brilliant red or orange interstripes anteri- orly and posteriorly on the side. Pointed tubercles on the infraorbital bones are observed in both species, but were found to be mostly present and prominent in D. choprae and mostly absent in D. flagrans, and are considered as possibly being seasonal in expression. Danio choprae is known from three localities along the Mogaung Chaung southwest of Myitkyina.
