✦ Synopsis
Variation in horn and body size of both sexes of Xylotrupes gideon australicus is normally distributed with no evidence of dimorphism in either sex. This contrasts with that of X. gideon gideon, in which males are dimorphic for horn length, but horn size varies within morphs. Males of X. gideon australicus are generally larger than females, but the distributions of all characters, except tarsal length, overlap considerably. Males have longer legs, presumably to facilitate mating.
