Superficially resembes G. basalts (LeConte) but keys out to G. alternatus Pierce in his key to the species (1912, p. 160, 162). However, knullorum is much smaller and in no way resembles the latter. G. knullorum can be separated easily from basalts as the latter has the third tarsal segment much larger than second. G. knullorum is a link between the subgenera Gerstaeckeria Champion and Philopunta Pierce, having characters which link it to both groups. (Sleeper 1954)
