NotesNearest confirmed specimens are from Idaho and northern Colorado. If we can find an adult, that would be a good range extension. R. tucula is very similar to R. alberta, of which adults have been found in our area.

They deleted R. tucula from their list because of a lack of adults.

R. alberta is discussed as R. tucula in a larval key.

Has the original description of R. tucula. Ross notes that R. alberta and R. tucula are very similar, possibly formed by speciation due to isolation during the last glacial advance. Perhaps the R. tucula in Peckarsky et al 1985 are really R. albertae.
