Daying

Dario dayingensis is a small badid from a tributary of the Daying River in the Irrawaddy drainage of Yunnan Province, China. Known for some years before its description, it was identified as Badis dario but is much closer to D. hysginon. It has been maintained by a handful of private collectors, and given its rarity the emphasis should be on captive reproduction, with the fish kept alone.

Devario apogon is a small devario from southwestern Yunnan, China, where all known localities lie in the Daying river watershed. Narrow, indistinct vertical bars on the front of the flank, a wide, tapering P stripe behind them, and no barbels or lateral line separate it from similar congeners. It is apparently abundant in rivers, streams and even ditches, in clear or turbid water.

Schistura polytaenia is a nemacheilid loach known only from its type locality, an Irrawaddy tributary in Tengchong County, Yunnan, China. It appears never to have been exported for the aquarium hobby. Normally listed in Nemacheilus, it appears under Schistura in Kottelat (2012), and the specimens shown on the profile were identified on the basis of collection locality.

Crossocheilus burmanicus is a cyprinid from Myanmar plus northeastern India and western Thailand, in rivers draining to the Irrawaddy and Salween. It lives in clear, flowing streams over boulders, pebbles, gravel and sand, browsing the biofilm on submerged surfaces. Its dark lateral stripe does not extend into the caudal fin, which separates it from the fish traded as 'Siamese algae eater' or 'SAE'.

Schistura yingjiangensis is a nemacheilid loach known only from the Daying River, an Irrawaddy tributary in Yingjiang County, Yunnan, China. It appears never to have been exported for the aquarium hobby. Normally listed in Nemacheilus, it appears under Schistura in Kottelat (2012), as it does in Chen & Neely (2012) and Endruweit (2014).

Garra bispinosa is a cyprinid known only from its type locality, the Daying Jiang in the Irrawaddy basin, Yunnan Province, China. It is distinguished from other Garra in Southeast Asia and China by a quadrate proboscis on the snout, each lobe tipped with a single large tubercle. Nothing specific is recorded of its habitat.

Garra rotundinasus is a cyprinid native to the Yiluowadi Jiang, the upper Irrawaddy river system, in Yunnan province, southern China. Before its description it was confused with a congener now accepted to occur only in the Salween and Manipur basins. Both have a weakly-developed proboscis, but G. rotundinasus has a broadly rounded snout and more lateral line scales. It grows to around 185 mm SL.
