A scorpion with four pectines and other anomalies

Morphological anomalies of scorpions are rare, but a few case have been reported. In a recent papers, Rolando Teruel and José Guadalupe Baldazo-Monsivaiz report of a specimen of Mesomexovis punctatus (Karsch, 1879) (Vaejovidae) from Mexico with a combination of hermaphroditism, gynandromorphism, and pectinal duplication (i.e., presence of four pectines).

Abstract:
In the present note, we describe in detail an aberrant anomalous specimen of the scorpion Mesomexovis punctatus (Karsch, 1879) (Vaejovidae). This strange individual is an adult and exhibits a combination of hermaphroditism, gynandromorphism, and pectinal duplication (i.e., presence of four pectines); the latter represents the first report ever made of such teratology. It was collected by the authors in northeastern Guerrero State, Mexico.

Thanks to Rolando for sharing this very special discovery with me a few weeks ago!
