Figure 3 in Phylogeography and distribution of the freshwater razor clams Novaculina myanmarensis and N. gangetica in Myanmar, with notes on two doubtful nominal taxa described as Novaculina members (Bivalvia: Pharidae)

Figure 3. Median joining networks of Novaculina spp. based on the COI gene fragment. (A) N. gangetica (N = 8). (B) N. myanmarensis (N = 15). The circle size is proportional to the number of available sequences belonging to the given haplotype (the smallest = 1). The red numbers near branches indicate the number of nucleotide substitutions between haplotypes. The color filling indicate river drainage basins.
