Speciation in Thaparocleidus (Monogenea: Dactylogyridae) Parasitizing Asian Pangasiid Catfishes

Figure 5

Morphometric variability of the parasite attachment organ estimated by the first axis of principal component analysis. The nonspecific parasites (i.e., generalists) differ significantly from specific parasites. The generalists show significant higher variance in haptor morphometry than specific parasites.
