Male genitalia morphology of Leptidea sinapis reveals no significant intraspecific differences. One-way ANOVA for a. phallus length/vinculum width and b. saccus length/vinculum width. The sibling species L. reali is included as positive control. Only L. reali versus all L. sinapis groups is significantly different (p < 0.0001 for both analyses). The bars represent two standard errors. c. Canonical discriminant analysis based on phallus length, saccus length and vinculum width.
