Fig. 4. A. Plot of principal component analysis on Oxyloma effusum (L. Pfeiffer, 1853) (n = 19) and O. salleanum (L. Pfeiffer, 1850) (n = 46) shells collected from the type localities. Landmarked types and original figures are included for each species. Convex hulls are drawn from non-type shells examined. The centroid means of each species shown with oversize symbol. Outline drawings represent the mean form of each nominal species compared to the overall mean shape. B. The outlines of the two nominal species superimposed with O. salleanum in black and O. effusum in gray. The heat map deformation grid shows the shape change from the mean form of O. effusum to the mean form of O. salleanum. Vectors on landmarks show the direction and magnitude of change.
