Character variation in the scorpion Parabuthus villosus (Peters) (Scorpiones, Buthidae): A case of intermediate Zones
The scorpion Parabuthus villosus (Peters) shows variation in leg colors over its range. The distributions o f the color morphs are parapatric. A fairly narrow intermediate zone is found where the yellow and black legged morphs meet. A similar zone is present at the parapatric interface between P. villosus and P. brachystylus. Using multivariate morphometries the morphological variation was found to be insignificant between the color morphs, but intermediates between P. villosus and P. brachystylus show morphology in-between that of the presumed parental forms. Factors that may be involved in the maintenance of the step lines are also suggested. Finally, P. brachystylus is given subspecific status.
