The evolutionary relationship for the COX-1 gene of A. ceylanicum inferred using the Neighbour-Joining method. The evolutionary distances were computed using the Maximum Composite Likelihood method and are in the units of the number of base substitutions per site. There were a total of 257 positions in the final dataset. Evolutionary analyses were conducted in MEGA6
