The subfamily Dynastinae generally exhibits strong dimorphism among males. However, until recently, studies on dimorphism and allometry were limited to horns. Lycomedes is a neotropic genus that belongs to the subfamily Dynastinae and is restricted to the Andean region of Colombia, Ecuador, and Peru. Among the Colombian Lycomedes species, this study focuses on the L. reichei and allied species, which have been designated here as the L. reichei species group, that displays a dramatic allometry. Here, various morphological characteristics of the L. reichei species group were analyzed and an allometry was proven.
