Diagnosis:
Males. This species is separated from other Glyphoderus species
by the shape and placement of the pronotal horns and tubercles (see
illustration). Glyphoderus sterquilinus has the pronotum with
two horns in middle and two transversally elongated tubercles (sometimes
developed as horns) on basal half; horns on margin of central depression;
tubercles of basal half included in central depression; apical medial
horn with ‘‘arms’’ robust, with anteromedial
notch. Some specimens of G. sterquilinus have the posterior
pronotal tubercles on the central depression margin (observed particularly
in minor males), in this case, the shape of the medial horn will separate
this species from G. monticola. No morphological characters
were found to diagnose females of this species, females can be identified
only by association with males.
