Larva.

Braasch and Boonsoong (2010) have described new species sub nom. " Epeorus (Iron) longitibius  Nguyen & Bae, 2004 (questionable)": 20-22 (Figs 83-98). The deposition of the female larva is in ZMKU (80% alcohol).

Adult.

Unknown.

Eggs.

Unknown.

Distribution.

Region of Doi Inthanon (Chiang Mai province); alt 2000 m, III 1999; bottom sample (leg. R. Braasch).

Diagnosis.

In contrast tothe larva of Epeorus longitibius  with foretibiae 1.2 × length of forefemora, Epeorus thailandensis  has foretibia of equal length; forefemur of new species is with a small femoral spot, Epeorus longitibius  without such one; the gills 2-6 are quadrangular and gill 7 has a fold in Epeorus thailandensis  , but in Epeorus longitibius  gills 2-6 are elongated and gill 7 unfolded.

Habitat and biology.

The larvae of Epeorus thailandensis  live presumably in high mountain streams with high oxygen concentrations and a faster current where the substrate is mostly stony at an elevation of 2000 m.

Remarks.

Boonsoong and Braasch (2010) misidentified this species as Iron longitibius  Nguyen & Bae, 2004 (questionable). In this study, we have re-checked them and found , then we re-identified it as a new species, Epeorus (Iron) thailandensis  . The new species is different from the larva of Iron longitibius  by characters within length of foretibia, femoral spot, and gill shape of gills 2-7. In this observation, we propose as the new species.
