Scientific name: Distoechodon macrophthalmus Zhao, Kullander, Kullander & Zhang, 2009

The Red-wing fish (Distoechodon macrophthalmus) is a freshwater fish of the family Cyprinidae. Native range: Asia, known only from the Chenhai Lake, Chang Jiang basin in Yunnan Province, China.

Biology

Dorsal soft rays (total): 10; Anal soft rays: 12. Differs from all its congeners in having the highest number of lateral line scales (78-85, mostly 82), more pre-dorsal scales (34-39, mostly 36), and relatively bigger eye, being 7.97% vs. 6.37-6.98% in SL. Similar to Distoechodon multispinnis in having higher lateral line and predorsal scale counts, but can be easily distinguished by having larger eyes at the same body size.
