Abstract

Twenty-three morphological features of 140 specimens of Ophisops elegans were analysed in order to identify sexual dimorphism in west and northwestern populations of Iran. Sexual dimorphism is significant (P<0.05) in nearly all metric features except for trunk length (TL) and length of widest part of belly (LWB), and in only two meristic characters, the number of dorsal scales around mid-body (DSN) and the number of femoral pores (FPN). Males have a relatively longer snout-vent length (SVL) than females and males have generally relatively larger heads compared to females.
