FIGURE 4 in Like A Glove: Do The Dimensions Of Male Adanal Suckers And Tritonymphal Female Docking Papillae Correlate In The Proctophyllodidae (Astigmata: Analgoidea)?

FIGURE 4: Size distributions of Proctophyllodes troncatus adult females, adult males and nymphs with and without docking papillae. Body size was measured as the length of the idiosoma (µm) from the anterior margin of the prodorsum to the posterior region of the body excluding the terminal hyaline appendages in adult females and the opisthosomal lamellae in males. Nymphs were catego- rized as having docking papillae or lacking docking papillae. Adult females were significantly larger than adult males as indicated by an unpaired t-test (t38 = 22.6, P <0.001). Similarly, nymphs with docking papillae were larger on average than were those without docking papillae (t194 = 20.6, P <0.001).
