Figures 77–81 in Revision of genus-group taxa in the family Scorpiopidae Kraepelin, 1905, with description of 15 new species (Arachnida Scorpiones)

Figures 77–81: Variation in positions of trichobothria db and eb on the fixed finger of the pedipalp chela of scorpiopids. Figure 77. Bivariate scatter plot of normalized distal positions of db vs. eb referred to trichobothrium Et5 on the distal chela manus (a proxy landmark for base of fixed finger) for males (triangles, 57 species) and females (circles, 57 species). Biometrics and symbol color indicating trichobothrial generic assignments according to old trichobothrial diagnoses, in upper right page inset. Trichobothrium db is level with eb along the black diagonal line, distal to it above the line, and proximal to it below the line. Figures 78–79. Relation of distal positioning of db vs. eb to manus elongation. Scatter plots of distal position of db relative to eb vs. L/D ratio of manus for 58 male (78) and 54 female (79) adult scorpiopids. Abscissa scale is logarithmic. Gray lines are least squares regressions, showing correlation is weak for males and strong for females. Figures 80–81. Relation of distal positioning of db vs. eb to positions of trichobothria Dt and Eb 3 on manus. Scatter plots of distal position of db relative to eb vs. normalized position of Dt (80) and Eb 3 (81) for males (triangles, 56 and 57 species) and females (circles, 54 and 52 species). Least squares regression lines are shown for each sex (males, dark gray; females, light gray). Arrows in Figs. 77, 79–81 indicate "Alloscorpiops" citadelle with more proximal db and Eb , separated from other "Alloscorpiops" with distal db. R=Pearson´s correlation coefficient.
