Figures 265–268. Analysis of distal pectinal tooth shape and pedipalp chela manus basal trichobothriotaxy in microcharmids and buthids. Figure 265. Bivariate scatter plot of outer curvature angle Θ of distal pectinal tooth vs. carapace L in buthids (black and gray symbols; n = 267; 142 ♂, 125 ♀; 61 genera) and microcharmids (green symbols: n = 9; 3 ♂, 6 ♀; 2 genera). All four main clades of buthids represented: 'Buthus', 'Ananteris/ Isometrus', 'Charmus/ Uroplectes' and 'Tityus' groups. Members of 'Buthus' group are plotted as black symbols. Males plotted as triangles, females as circles. Intersecting lines subtending Θ are tangent on the outer (distal) margin at 1/3 and 2/3 along the longitudinal axis of the tooth. Gray line: linear least squares regression (R = –0.44, P <0.0001). Abscissa with logarithmic scale. Figure 266. Ranked vertical bar plot of data for outer curvature angle Θ in Fig. 265,. Color codes as in Fig. 265. Silhouettes are examples of distal tooth profiles. Figures 267–268. Distributions of configurations of basal trichobothria (Eb 1, Eb 2 and Eb 3) on pedipalp chela manus among four main clades of buthids. Relative position of Eb 1 and Eb 2 along proximal-distal axis of manus (267), and direction of opening of non-reflex angle formed by (Eb 1, Eb 2, Eb ) triad (268). Data from n = 604 buthids, and n = 3 microcharmids (classified under 'Charmus/ Uroplectes' group).
