Zygoneura (Pharetratula) subdivergens

Zygoneura (Pharetratula) subdivergens (Mohrig & Mamaev, 1990) (Figs 11A–D) Pharetratula subdivergens Mohrig & Mamaev, 1990 [Mohrig et al. (1990): 227]. Zygoneura (Pharetratula) divergens (Mohrig & Mamaev) [Menzel & Mohrig (2000): 587; Zhang et al. (2010): 41; Shin et al. (2014): 562]. Material examined. China, Zhejiang Province, Anji, Mt. Longwang, 30°13’55.2’’ N, 119°14’38.4’’ E, 988 m a.s.l., malaise trap, coll. Caixia Liu: 1♂, 16.VII.2018 [LW-QMT382]; 1♂, 17.VII.2018 [LW-XG397]; 1♂, 16.X.2018 [LW-XG566-2]; 1♂, 18.XI.2018 [LW-XG806-2]. Remarks. This is the first report of this species from China. This species greatly resembles Z. (Pharetratula) longa Zhang & Wu in the subapical and sub-basal megasetae on the gonostylus. However, it can readily be differentiated from the latter in the stouter gonostylus rather than the more slender one (Fig. 11B). Z. (Pharetratula) subdivergens (Mohrig & Mamaev) also resembles Z. (Pharetratula) divergens (Mohrig & Mamaev) in the stout gonostylus with subapical and sub-basal megasetae. However, it can easily be distinguished by the pair of distinct lobes on the ventral medial margin of the gonocoxa (Fig. 11B). Distribution. China: Zhejiang (this study), Russia (Mohrig et al. 1990; Menzel & Mohrig 2000).
