Remarks.

The genus Rhithrogena is the most diverse in the Holarctic, with numerous species also in the Palaearctic Asia. However, it seems to be under-representedinSoutheast Asia. Braasch and Boonsoong (2009) described Rhithrogena siamensis Braasch & Boonsoong, 2009 from northern Thailand, this species also occurs in the northeastern and western parts of Thailand. Only two further species of the genus can be found in this area: Rhithrogena parva Ulmer, 1939 from Taiwan ( Ulmer 1912) and Rhithrogena diehliana Braasch & Soldán, 1986 from Sumatra ( Braasch and Soldán 1986c).
