Figure 98 in A review of the genus Leiurus Ehrenberg, 1828 (Scorpiones: Buthidae) with description of four new species from the Arabian Peninsula
Figure 98: Selected morphometrics of Leiurus, Cicileiurus, Cicileus and Compsobuthus compared to other Buthus group scorpions. A–B. Scatter plots of the fraction of fixed finger length distal to db (A) and est (B) vs. the ratio of movable finger length to carapace length. Each point represents one sex of one species. Larger ordinate values correspond to more basal positions of the trichobothria, and larger abscissa values to longer pedipalp fingers. There was a significant inverse correlation between relative length of the portion of the fixed finger distal to db and est (R = -0.6534, -0.5488, respectively), and the relative length of the movable finger (the latter being a measure of elongation of both fixed and movable fingers). Highlighted symbols show that Leiurus (light magenta circles), Cicileiurus (red triangle), Cicileus (green squares) and Compsobuthus (yellow circles) are located in the lower right halves of the plots, i.e. all have relatively elongated fingers and more distal placement of both db and est. Gray circles are data from other Buthus group species. C. Scatter plot of the fraction of fixed finger length distal to db vs. the fraction distal to est. The strong positive correlation (R = 0.8052) indicates a tendency for db and est to move together towards more distal locations as the fixed finger becomes more elongated. Species above the diagonal (solid blue) have db proximal to est, and those below have db distal to est. Solid gray lines in A–C are fits by least squares regression through all points. D. Scatter plot of pedipalp femur L/W (a measure of pedipalp elongation) vs. carapace L (a measure of body size). These two variables were not significantly correlated (R = 0.094). Data were compiled from the literature and specimens in the authors collections for 38 genera and 203 species representing the majority of taxa in the Buthus group, including both males (N = 124) and females (N = 97).

Figure 95 in A review of the genus Leiurus Ehrenberg, 1828 (Scorpiones: Buthidae) with description of four new species from the Arabian Peninsula
Figure 95: Variation in key diagnostic biometrics of adult Leiurus spp. A. Cumulative distributions of position of trichobothrium db relative to est on pedipalp fixed finger for: L. abdullahbayrami (53), L. brachycentrus stat. n. (11), L. hebraeus stat. n. (38), L. macroctenus sp. n. (176), L. quinquestriatus (61), L. haenggii sp. n. (158), L. arabicus sp. n. (87) (number of fingers measured in parentheses). Data for males and females were pooled. The db–est distances were normalized to pedipalp movable finger length (chord length from finger tip to external articular condyle), with positive values indicating db distal to est, negative values indicating db proximal to est. Distributions of L. haenggii (µ = 0.06367) and L. arabicus sp. n. (µ = 0.06671) were not significantly different (P = 0.405148, t test), indicating a close relationship between these species. Distribution of L. quinquestriatus (µ = 0.047313) was significantly different from those of L. haenggii and L. arabicus (P = 0.000102 and 0.000030 respectively). B. Scatter plot of morphometric ratios of mid-pectine sensillar margin L (MPSM, indicated in inset) to metasoma I W, and to carapace L, showing differences in relative pectinal tooth size in females of nine species of Leiurus. C. A subset of the female data in Figure 95B, plotted as cumulative distributions of morphometric ratio of mid-pectine sensillar margin L to metasoma I W. Distributions of L. haenggii (µ = 0.102268) and L. arabicus (µ = 0.10432) were not significantly different (P> 0.1, K-S test). D. Scatter plot of morphometric ratios of mid-pectine sensillar margin L to metasoma I W (relative size of pectine teeth), and metasoma II L/W (slenderness of metasoma II) for females of nine species of Leiurus.

Figure 94 in A review of the genus Leiurus Ehrenberg, 1828 (Scorpiones: Buthidae) with description of four new species from the Arabian Peninsula
Figure 94: Comparative analysis of granulation on tergite III of female Leiurus. A. UV fluorescence image of tergite III medial intercarinal surface of L. quinquestriatus (Egypt). B. Mask of granulation pattern on medial intercarinal surface from image in Figure 94A. C. Enlarged view of tergite III granulation in rectangular area indicated in Figure 94A. Granules were identified as local maxima of fluorescence intensity with contour shadows cast by directional UV illumination, and were modeled by elliptical regions-of-interest (ROIs). Parameters of granule ROIs were measured in ImageJ 1.44 (Rasband, 1997–2011). Area of granulometric analysis was restricted to surfaces bounded by the lateral and posterior marginal carinae, and a line passing through oblique, anterior transverse rows of enlarged granules (granules along carinae and bounding lines were omitted). D. Scatter plot of mean granule diameter vs. total granule area for 4 species of Leiurus (L. arabicus sp. n., L. haenggii sp. n., L. hebraeus stat. n. and L. quinquestriatus). Each point represents granulometric data derived from tergite III of one scorpion specimen (bilaterally, as shown in Figure 94B). Data were extracted from 18,423 ROIs from 36 scorpions. For each specimen, total granule area (a measure of density of granulation) was computed as sum of areas of all ROIs, and mean ROI diameter (a measure of coarseness of granulation) as the mean value of the maximum diameters of all granule ROIs. For comparative analysis, images from different size scorpions were resampled to equalize the distance between left and right posterior marginal granules of the lateral carinae (arbitrarily set to 4,000 units or pixels; linear dimensions expressed as [pixel], areas as [pixel2]). The total granule area separated the species into 2 groups: i.e. sparsely granulated (L. arabicus, L. haenggii) and densely granulated (L. hebraeus, L. quinquestriatus). In contrast, the distributions of ROI diameter were broadly overlapping. E. To obtain a more sensitive comparison of the coarseness of granulation, normalized cumulative distributions of single ROI areas for 3 species of Leiurus were computed (inset indicates number of scorpions analyzed). Relative horizontal positions of these curves indicated increasing coarseness of granulation, in rank order: L. haenggii
