Figs. 8–14 .

Material examined. One male, China: Heilongjiang Province, Harbin City, Alejin Island, Songhua River ( Fig. 14 ), 45.80 N, 126.64 E, 113 m, April 15, 2019, Rui-Hang Dong (ICJUST).

Remarks. Identity of this male specimen is undetermined. Additional material, especially the female and egg are needed for specific placement. This specimen is most similar to F. mongolica ( Klapálek, 1901) known from Mongolia, Russia, and Shaanxi Province of China ( DeWalt et al. 2019).
