Introduction and Adaptation of Isometrus maculatus (DeGeer, 1778) (Scorpiones, Buthidae) in Arid and Desert Formations

摘要

Isometrus (Isometrus) maculatus is the most widely distributed scorpion species in the world. Its distribution has an anthropogenic background, probably going back to the great naval voyages of the 16th century. I. (I.) maculatus is found in most tropical and subtropical coastal regions of the world, and the question concerning its original area of distribution has been addressed often. Lourenco & Huber (2002) suggested that the original area of distribution of I. (I.) maculatus could be Sri Lanka since this is the only region in the world in which I. (I.) maculatus is found under really wild conditions inland.
