Remarks.

Dicrotendipes flexus (Johannsen) closely resembles Dicrotendipes nervosus (Staeger) in the structure of hypopygium, but can be separated by the apparently disjunct distributions and fewer setae on R and R1, (21−26 in Dicrotendipes flexus , more than 35 in Dicrotendipes nervosus ). All examined Chinese specimens comply with the description of Johannsen (1932) and Hashimoto et al. (1981).

Distribution.

China (Hubei, Guangdong and Shandong Province); Australia; Japan; Indonesia.
