Remarks.

Epeorus is widely distributed in the Holarctic, northern portion of the Neotropical, Palaearctic, and Oriental regions ( Kluge 2004). In tropical Southeast Asia, species of this genus have been reported and described by Braasch (1990, 2011), Braasch and Boonsoong (2010), Braasch and Soldán (1979, 1984c), and Webb and McCafferty (2006). Nguyen and Bae (2004a) provided larval descriptions and a key to six species of Vietnamese Epeorus ; this was the first comprehensive taxonomic study of the larvae of Epeorus from tropical Southeast Asia. The first record of Epeorus in Thailand is of Epeorus aculeatus Braasch (1990) from Doi Inthanon National Park, Chiang Mai province. Recently, the first Thai imago of Epeorus aculeatus was described by Webb and McCafferty (2006) from Chiang Mai province. Originally, Epeorus unicornutus was recorded from Himalayas ( Braasch 2006b) although it had been already collected in Thailand December 1987/1998 from the river Nam Lang, Soppong / Pangmapa, Mae Hong Son province (Braasch, unpublished). Currently, seven species of Epeorus are known from Thailand ( Braasch and Boonsoong 2010).
