Abstract:In China, the rapid racerunner (Eremias velox) is considered to be restricted to Ejinaqi, Dunhuang Basin, and north areas of Xinjiang Uygur Autonomous Region. The scalation and their morphological traits were used to quantify the morphological variation and discuss the subspecific status of rapid racerunner in Xinjiang. A total of 287 adult specimens were collected and categorized into 5 geographical populations: Qoqek, Ili, Dzungarian Basin, Urumqi and Turpan Depression. The frequency and range of head scale (supralabial, infralabial, postmental, collars) and body scale (femoral, interfemoral, ventral scales and transverse rows of ventral scales) were measured. The coefficient of variation (CV) of scales was calculated. Finally, the scales could be divided into three categories according to the CV: (1) no variation (transverse rows of ventral scales); (2) occasional variation (supralabial, infralabial and postmentals) with CV less than 30%; and (3) continuous variation (femorals, interfemorals, collars and transverse rows of ventral scales) with CV more than 30%. Coefficient of Difference (CD) among the 5 geographical populations in 8 morphological and 7 scalation traits were calculated also, however, no significant morphological differentiation supported the subspecies divergence which had been occurred in these regions. Our results suggested that more comprehensive investigation should be conducted to determine the validity of the subspecies Eremias velox roborowski.
