FIGURE 22. Cluster analysis of burrows produced by Mastigoproctus giganteus, Gorgyrella inermis, and Hogna lenta. Spider Clusters A, B, and C are maintained with the addition of morphologically similar whip scorpion burrows, and G6 forms a new cluster. Unique burrow architectures produced by M. giganteus form a separate cluster. Formatting and key is the same as in Figures 16 and 21. Mazeworks (MW), U-shaped burrows (US), and subvertical ramps (SR) are produced only by M. giganteus.
