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).
