Zygoneura (Pharetratula) flavicornis ( Mamaev, 1968)

( Figs 7A–C )

Pharetratula flavicornis Mamaev, 1968 [ Mamaev (1968): 611; Mamaev (1976): 138; Gerbachevskaya-Pavluchenko (1986): 56; Mohrig et al. (1992): 32; Yagi & Sawada (2000): 37].

Zygoneura (Pharetratula) flavicornis (Mamaev) [ Menzel & Mohrig (2000): 582; Zhang et al. (2010): 41; Shin et al. (2014): 564].

Material examined. 2♂♂, China, Heilongjiang Province, Mt. Maoer nature reserve , 45°15’ N, 128°13’ E, 26.VII.2008, sweep net, leg. Sujiong Zhang [ SM00188 , SM00189 ] .

Remarks. The studied specimens (2♂♂: SM00188–00189) were earlier recorded mistakenly as Z. (Pharetratula) bidens (Mamaev) by Zhang et al. (2010), which are now identified correctly as Z. (Pharetratula) flavicornis (Mamaev) . This species resembles Z. (Pharetratula) disparilis Zhang & Wu in the appearance of gonostylus. However, it can easily be distinguished from the latter by the gonostylus with two megasetae parallel to each other and not overlapping in ventral view ( Fig. 7B ). This species is a new record to the Chinese checklist.

Distribution. China: Heilongjiang (this study), Korea (North and South), Russia ( Shin et al. 2014).
