Figures 90–91: Scaling of relative size of median ocular tubercle with relative size of median eyes in the genus Leiurus. Ordinates of scatter plots are the ratio median ocular tubercle width/ carapace L, and abscissas are the ratio median eye diameter/ carapace L, in males (90) and females (91). Plotted symbols represent measurements from a single sample of each species, extracted or estimated from published images and data, or from our own material. Lines are least squares regression fits, and the corresponding correlation coeeficients R, and P-values are indicated. In both sexes, L. gubanensis sp. n. is well separated from other species in having the largest eyes in the genus.
