Fig. 4. Posterior hook morphology of Raillietiella orientalis, collected from snakes in the Northern Territory of Australia. Barb length (AB) versus overall length (BC) of pentastomids measured from four snake species: Northern death adder (Acanthophis praelongus; black diamonds), lesser black whip snake (Demansia vestigiata; grey circles), keelback (Tropidonophis mairii; grey triangles), and water python (Liasis fuscus; dark grey squares). (a) Raw hook measurements uncorrected for pentastome body size, note potential species clusters; (b) Hook measurements corrected for pentastome body size (residual scores from a linear regression of hook measurements against pentastome body size), note that clusters now disappear.
