Zygoneura (Pharetratula) divergens ( Mamaev, 1976)

( Figs 6A–D )

Pharetratula divergens Mamaev, 1976 [ Mamaev (1976): 138].

Zygoneura (Pharetratula) divergens (Mamaev) [ Menzel & Mohrig (2000): 582; Zhang et al. (2010): 41; Shin et al. (2014): 562].

Material examined. 2♂♂, China, Zhejiang Province, Anji, Mt. Longwang , 30°14’6’’ N, 119°14’42’’ E, 681 m a.s.l. 18.XI.2018, malaise trap, leg. Caixia Liu [ LW-XG832 , LW-XG451 ] ; 1♂, Zhejiang Province, Lin’an, Mt. Tianmu , 30°12’7.2’’ N, 119°15’18’’ E, 979 m a.s.l., 29.VII.2018, malaise trap, leg. Zuluan Chen [TMM-925-2] .

Remarks. This species greatly resembles Z. (Pharetratula) subdivergens (Mohrig &Mamaev) in the morphology of hypopygium. However, it can readily be differentiated from the latter in the ventral medial margin of gonocoxa without distinct lobes and gonostylus with two megasetae near the ventral side ( Fig. 6B ). This is the first record of this species from China.

Distribution. China: Zhejiang (this study), Russia ( Mamaev 1976; Menzel & Mohrig 2000).
