Figures 106–109 in Review of Grosphus Simon 1880 with description of Teruelius gen n a new buthid genus from Madagascar (Scorpiones Buthidae)

Figures 106–109. Biometric scaling of spiracles of sternite IV in Grosphus, Neogrosphus and Teruelius gen. n. Figures 106–107. Logarithmic scatter plots showing scaling of spiracle length/ width vs. carapace length in males (106), and females (107) of Grosphus, Neogrosphus and Teruelius gen. n. Male plot: purple star shows spiracle L/W of outgroup taxon Pseudolychas ochraceus. Figures 108–109. Logarithmic scatter plots showing scaling of spiracle width/ carapace length vs. carapace length in males (108), and females (109) of Grosphus, Neogrosphus and Teruelius gen. n. Blue lines are least squares linear regression fits of scaling trends for Grosphus. R = Pearson correlation coefficient, and P value as indicated. Horizontal gray lines are proposed diagnostic thresholds.
