Abstract: Sexual dimorphism is a widespread phenomenon throughout the animal kingdom and a key topic in evolutionary biology. In this study, we quantified patterns of sexual dimorphism in two hynobiid salamanders (Hynobius leechii and Salamandrella keyserlingii) from Chinese populations. Sexual size dimorphism did not occur in either species, despite differences in body shape traits. Likely related to fecundity selection, females have relatively longer trunks in both species. Female S. keyserlingii have larger heads likely due to reproductive investment and ecological selection, whereas larger forelimb and hindlimb width in male H. leechii may be related to reproductive behaviour.
Key words: Asian salamander, Hynobiidae, morphology, sexual size dimorphism
