Zygoneura sciarina Meigen, 1830: 305 .

Specimens examined. 1 Male, China, Heilongjiang province, Yichun, Wuying, Fenglin nature reserve, 68 xiaoban, 48°05΄N, 129°19΄E, 24.VII.2008, Yi-Ping Wang [SM00190]; 1 male, China, Heilongjiang province, MT. Maoershan nature reserve, 45°15΄N, 128°13΄E, 26.VII.2008, Su-Jiong Zhang [SM00157].

Remarks. This species belongs to the subgenus Zygoneura , first recorded from Germany and widely distributed in Europe ( Menzel & Mohrig 2000). It is newly recorded from China (Heilongjiang). It is distinguished by a bare posterior pronotum and three megasetae on the gonostylus, one arising from the apical forth and the other two from apical third. The materials examined show distinct intraspecies variation in body length. The Chinese specimens are 2.36–2.41 mm, much shorter than the European specimens, which are 2.7– 3.5 mm ( Menzel & Mohrig 2000).
