[Kyerematen & Andersen (2002) used the phaselus group, which was an earlier division into species groups and is now included in the muscicola group.] The species is similar to R. subtilis Kyerematen & Andersen from Costa Rica and R. ramirezi Kyerematen & Andersen from Mexico, but differs from both by having a higher antennal ratio (0.7 – 0.8, as opposed to about 0.4), and having anal tergite bands of the V type as opposed to the H type.	en	Wang, Xinhua, Guo, Yuhong (2004): A review of the genus Rheotanytarsus Thienemann & Bause from China (Diptera: Chironomidae: Tanytarsini).
