Based on the DMR test, 18 members of the nasuta-albomicans complex of Drosophila are constructed into clusters and named in the hierarchical form from the lowest to the highest mean wing width. The members belonging to each cluster have insignificant differences. In males, (Fig. 2a), females (Fig. 2b) and both males and females together (Fig. 2c), 8, 6, and 4 clusters are made respectively. All the members are with overlapping clusters.
