Remarks.

A brief comment on the appropriate placement of Compsoneuria (Siamoneuria) kovaci in Braasch and Boonsoong (2010) is required. Larval diagnosis of Compsoneuria(Siamoneuria) is in contradiction to that of Compsoneuria , namely in lacking the combination of long, sharply pointed supracoxal spurs, black spotting on the head capsule and femora, and narrow, apically pointed glossae. Siamoneuria cannot belong in the genus Compsoneuria but probably deserves its own status; it appears to be a morphospecies whose characters are not in accordance with other known genera. For a final definition, important missing details of mouthparts and eggs should be included. For now, we see it as a species as "INCERTAE SEDIS" ( Braasch and Boonsoong 2010). So, further studies and more specimens are needed to clear taxonomic of this species.

Larva. Braasch 2006a: 50-51, Figs 9-21.

Adult.

Braasch 2006a: 49-51, M, Figs 1-8.

Eggs.

Unknown.

Distribution.

Nam Lang river, Soppong, Mae Hong Son province,

Diagnosis.

Larva is conspicuous due to emarginations on gills 2-6, gill 7 being narrowly lanceolate, the head without markings, and the body with paired paramedian spots on tergites 5-8, large median spot on 9, and three distantly arranged small spots at anterior margin of tergite 10.

Habitat and biology.

The habitat of the single larva found was submerged roots of a tree standing at the river bank.
