Distribution.

Khun Kon Waterfall (Chiang Rai province).

Diagnosis.

The larva of Epeorus martinus can be distinguished by the following characteristics: pairs of moderately long acute submedian spines on the abdominal terga 1-9, large but narrow gill 1 forming a sucking disc and gill 7 being unfolded.

Habitat and biology.

Epeorus martinus larvae are found in mountain streams with a moderate current, at an elevation of 300-2800 m (Nguyen and Bae 2004a).

Remarks.

Webb and McCafferty (2008) did not recognize the subgenera of Epeorus (e.g. Belovius, Iron). However, we hold on the validity of subgenus Belovius and Iron within genus Epeorus (Boonsoong & Braasch, 2010). Therefore, we propose Iron martinus Braasch & Soldán, 1984 = Epeorus (Iron) martinus Braasch & Soldán, 1984
