Stonefly Genus Doroneuria (Golden Stones)

This less common western genus currently has only two species. Doroneuria theodora & Doroneuria baumanni (mostly coastal)

Calineuria and Doroneuria nymphs both lack anal gills and can be confused, but Doroneuria has a ridge of fine hairs running down the center of its body dorsally and is not as dramatically marked. The adults often have very short wings and also lack the striking head markings of Calineuria. The adult males have large quadrangular hammers that are almost twice as long as wide.
