UROCTONIDAE
Mello-Leitao, 1934

This family consists of one genus and three species [Updated 26.06.26]. The taxa in this family have been trasnferred from Chactidae.
Before this, the genus Uroctonus was placed in the family Vaejovidae.

Sharma et al., 2019 have reassed the relationships of Vaejovidae and the high-level classification of Scorpiones and one conclusion from this study is that the status of Uroctonus Thorell, 1876 is incertae sedis, meaning that it doesnt belong to either Vaejovidae or Chactidae. More studies are necessary before its family placement can be decided. But see current status below.

SPECIES FILES:
This list of genera and species is based on Prendini (2026) and will be updated with new taxonomic decisions as soon as possible. The list was originally created from Fet et al.(2000). September 2019: Subspecies are 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)
