Figures 93–96 in Description of the adult male Scorpiops tongtongi Tang, 2022, with further comments on the genus Scorpiops Peters, 1861 in China (Scorpiones: Scorpiopidae)

Figures 93–96. Application of "condyle method" upon a modified caliper (93–95) using the right chela of an adult male S. xui as the example, and pinned specimens of S. tongtongi (96). In reality, to avoid the deviation caused by the curvature of chelal fingers, the chela needs to be positioned in a vertical direction (Fig. 94); this obviously depends on the width of the L-shaped plate. The chela does not have to be orthogonal to a horizontal plane since the rotation around the pitch axis does not affect the width measured, as long as the roll and yaw axes are fixed (thus defining a 2D plane) based on the rod (however, this could be difficult by manual measurement).
