Clark (1917, p. 104) appears to have erected this genus on the premise that Studeria elegans (the type species of Studeria) does not appear to be congeneric with S. recens. However, Clark (1917) fails to give diagnostic characters by which to differentiate these genera. Kier (1962) reports that after studying Agassiz\'s figure he cannot identify characters of sufficient importance to warrant generic distinction. Having studied both type species we are in agreement with Kier, the type species are almost certainly congeneric and therefore Hypselolampas should be regarded as a subjective junior synonym of Studeria.
