Figures 91–92 in Description of the adult male Scorpiops tongtongi Tang, 2022, with further comments on the genus Scorpiops Peters, 1861 in China (Scorpiones: Scorpiopidae)

Figures 91–92. Scorpiops atomatus, female from Gyaca County, Shannan, Tibet, right chela in dorsal aspect. Figure 91. Comparison of "axis" and "baseline" methods. Red curves: rough fitting of chela outline; blue line: axis (chela-L in this paper); cyan line: maximal distance and orthogonal to axis; green lines: orthogonal to axis and passing the apexes of both arcs; purple line: connection between to apexes; pink line: baseline of the inner arc; yellow lines: orthogonal to baseline and passing the apexes of both arcs. Figure 92. "Squeezing method"; red rectangle confined the chela using four points. The left side of this rectangle is determined by P in (chela-W) (or P te (chela-L)) and P te (chela-W); its right side is a parallel line tangential to the outer arc.
