Remarks. Rhyacophila manicata belongs to the R. gyamo Species Group. This species group now contains 7 species. Rhyacophila gyamo SCHMID 1970 was first recorded from India, and then was recognized from Thailand (BUNLUE et al. 2012; THAPANYA et al. 2004). Rhyacophila immaculata MEY 1996 and R. ranga OLÁH 1987 are Vietnamese endemics. Rhyacophila orientalis KIMMINS 1953 and R. suah MALICKY & CHANTARAMONGKOL 2009 (in Malicky 2009) are known exclusively from Myanmar and Thailand, respectively. Rhyacophila manicata, previously known from Myanmar (KIMMINS 1953), is now also known in China (Si-chuan); together with R. ligulula MALICKY & SUN 2002 (Si-chuan), the number of Chinese species in the R. gyamo Species Group is brought to 2.
