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.
