Remarks.

The heptageniid mayfly genus Compsoneuria was reviewed by Webb et al. (2006). Eleven species were revised from Afro-tropical and Oriental regions. Compsoneuria larvae were found abundantly in lowland rivers on mainland Southeast Asia. There are three species of Compsoneuria mayflies reported from Thailand (Braasch 1990; Braasch 2006a; Braasch and Boonsoong 2010). Compsoneuria larvae occur among submerged vascular plants or roots.
