03CC6F22921C3B7BFF2C7DE2BD19A8FC.taxon	discussion	Remarks. The new species is somewhat similar to R. qinghaiense Yang, 1998 from Qinghai province of China, but may be separated from the latter by the length / width ratio of the first flagellomere, the bristles on the fore tarsomere 5 and the shape of the cercus. In R. qinghaiense, the first flagellomere is 5.9 times longer than wide; the bristles on fore tarsomere 5 are normal and the cercus is long, thinner onwards (Yang et al. 2011).	en	Tang, Chufei, Wang, Ning, Yang, Ding (2016): Rhaphium (Diptera: Dolichopodidae: Rhaphiinae) from China with six new species.
