Figures 134–135: Morphometric analysis of scorpion telson shape. Bivariate scatter plots of principal component scores, PC1 vs. PC2 (134) and PC3 vs. PC4 (135) explaining 94.36% of the variance of telson lateral profiles parametrized by 7 variables (136): LV (vesicle length), LVA (anterior vesicle length), HV (vesicle depth), HA (aculeus height), SA (aculeus ventral curve length), BT (aculeus basal thickness), and AT (area of subaculear tubercle). First 6 variables normalized to telson length (TL), AT normalized to area of vesicle bounding box (LV.HV). Axis labels list associated variables with factor loadings> 50% (positive or negative). Sample: 2562 profiles; families: 20; genera, 224; species, 1866 (1858 extant, 8 extinct); sex, 1340 ♂ + 1213 ♀ + 9?. Data compilation as in Lowe et al, 2019.
