Abstract EN
Sexual dimorphism is often observed in Crustaceans.
Considering the great diversity of this subphylum, only few reports are found in the literature and most are mainly based on traditional morphometry.
The present study uses geometric morphometrics analysis to identify sexual dimorphism by shape variation in the overexploited semiterrestrial crab Ucides cordatus, species with great social and economic importance in South America.
Comparative morphology analyses were performed by using the outer face of the propodus of major cheliped, dorsal and anterior region of carapace shape.
Significant differences in shape between sexes were detected in these body areas.
The causes of dimorphism presented in this species are not clear but, analogous to other possibly associated species, it may be inferred that the causes are with adaptations to body ability of reproductive potential (females), and of reproductive behaviour and agonistics encounters (males).
Additional analyseson courtship displays and other reproductive aspects should provide better comprehension of functionality of this morphological differentiation.
