Genus Heteroscorpion Birula, 1903

Diagnosis. Scorpions of large size, with female adults reaching 60 to 145 mm and male adults 100 to 187 mm. Sexual dimorphism strongly marked, mainly by the allometric growth shown in males. Two pairs of lateral eyes. Metasomal segments I to IV very flattened laterally with single ventral median carina. Telson weakly elongated in both sexes. Dentate margin on fingers with numerous granules arranged on their basal twothirds, and forming two parallel series of granules on its distal portion; a few stronger accessory granules may be present. Trichobothriotaxy of type C, neobothriotaxic majorante (+), plethotaxic in one species ( H. magnus ) on the patella and chela (chela + fixed finger). Hemispermatophore (see figures 4–5 in Lourenço & Goodman 2002). Venom glands presumed to be simple.

Geographic distribution: both the family and genus are endemic to Madagascar.
