The data indicates that the S. spindale population from Nepal and Bangladesh may be a separate species to the population from the rest of Southeast Asia as there is a high level of distance seen within the species as a whole yet when each population is analysed separately this level drops dramatically and the distance between the populations is comparatively high.
