Remarks. This species was described by Bernhauer (1943) from Sichuan. It was recorded from Shaanxi and Hubei by Shavrin (2018). Habitus as in Fig. 96 . Male abdominal tergite VIII as in Fig. 102 , and male abdominal sternite VIII as in Fig. 103. A comparison of the shapes of the aedeagi of G. szechwanensis from different localities shows insignificant variability of the apical portion of the median lobe and the parameres ( Figs. 104–111 ). The distribution of the species in China is shown in Fig. 112 . The species is here recorded from Henan and Ningxia Autonomous Region for the first time.
