Figures 8–9 in Etudes on iurids, I. The orthobothriotaxic pattern of Iuridae, with observations on neobothriotaxy in genus Iurus (Scorpiones: Iuroidea)

Figures 8–9: Positional differences in chelal trichobothria between Calchas and Iurus. 8. Trichobothrium esb is not positioned inline with the other external trichobothria in Calchas, whereas in Iurus, esb is inline with these trichobothria; trichobothrium db is positioned significantly more basal, at fixed finger base, in Calchas, whereas in Iurus db is positioned distally, midfinger. 9. Trichobothrium Db is positioned more distal and dorsal (i.e., left in the figure) of the external carina (E) in Calchas, whereas in Iurus Db is positioned considerably basal and ventral of the E carina (i.e., right in figure).
