A small family, which consists only of 1 genus and 6 species [Updated 20.02.14]. The family is endemic to Madagascar.

Lourenco (1996) elevated Heteroscorpionidae Kraepelin, 1905 to family rank based on Stockwell's (1989) phylogeny. Soleglad and Fet (2003) relegated Heteroscorpionidae to a subfamily of Urodacidae Pocock, 1893 and later to Hemiscorpiidae. Prendini and Wheeler (2005) rejected these changes, and reinstated Heteroscorpionidae. The Scorpion Files has so far followed Soleglad & Fet (2003), but after Monod and Prendini's (2014) analysis of most taxa inclued in Hemiscorpiidae and the revalidation of Hormuridae, I have chosen to reinstall Heteroscorpionidae as a valid family in The scorpion Files as proposed by Prendini and Wheeler (2005) and Monod and Prendini (2014). See Hormuridae for more details.

Scorpions in this family are probably not kept in captivity.

No data have been found, but the scorpions in this family are probably not medically important.

SPECIES FILES: This list of genera and species is based on Fet et al.(2000). Subspecies is not included in the list. I try to update the list as additions and changes are published. * denotes changes after Fet et al. (2000). I will be grateful for information about new development in the taxonomy of this family. For information about synonyms and bibliographies, see Fet et al. (2000)
