Amongst mammals, femalebiased sexual size dimorphism (SSD) is rare and it occurs mostly in species where reduced male intrasexual competition is present. Reverse SSD has been reported for Old World porcupines Hystrix spp. We compared weight and six metric body measurements of 40 male and 42 female crested porcupines from Southern Tuscany, Italy. No significant difference was observed between sexes. The monogamous mating system of porcupines, sharing parental care, together with no evidence of territoriality, militate against previous claims of SSD presence, probably due to small sample size and inappropriate statistical analyses.

Abstract
Amongst mammals, femalebiased sexual size dimorphism (SSD) is rare and it occurs mostly in species where reduced male intrasexual competition is present. Reverse SSD has been reported for Old World porcupines Hystrix spp. We compared weight and six metric body measurements of 40 male and 42 female crested porcupines from Southern Tuscany, Italy. No significant difference was observed between sexes. The monogamous mating system of porcupines, sharing parental care, together with no evidence of territoriality, militate against previous claims of SSD presence, probably due to small sample size and inappropriate statistical analyses.
