Body malformations in a few Iranian scorpions

Body malformations and anomalies in scorpions are reported from time to time. One of the most famous cases was Pepe - The two-tailed scorpion (a Centruroides excilicauda with two tails).

Jahanifard and co-workers have now reported cases of pedipalp and telson anomalies in a few Iranian scorpions.

The developmental anomalies are reported in this study. The first and second abnormally are presented in right pedipalps of Paraorthochirus and Orthochirus (Buthidae) while Paraorthochirus pedipalp just includes coxa, trochanter and without other parts (femur, patella, movable and fixed finger). The right pedipalp of Orthochirus specimen has abnormally too; it has all parts of pedipalp except complete fixed finger. In both of scorpions, the left pedipalp is normal. Another case is present in venom vesicle of Hemiscourpius (Hemiscorpiidae). Pictures and morphometric measurements for three specimens are given.
