The family Urodacidae was abolished by Soleglad, Fet & Kovarik in April 2005, and Heteroscorpion was
transfered to the new family Hemiscorpiidae and Urodacus was transfered to Scorpioniddae.|
This family consists only of 2
genera with 24 species [Updated 26.08.04].
The genus Urodacus was originally placed in the
Scorpionidae (subfamily Urodacinae), but was recently elevated
to family status by Lorenzo Prendini (This is not reported in
Fet et al. (2000), but the family status is recognized by Dr.
Fet (pers. comm.)). The elevation to family status was based
on a cladistic study of the superfamily Scorpionoidea. See
Prendini's publication for details (see below).
In a major revision of higher scorpion systematics by Soleglad & Fet (2003), the genus Heteroscorpion
was also included in Urodacidae. This genus was previously placed in Heteroscorpionidae, which is abolished (and before that, Ischnuridae), and
is endemic for Madagascar. Urodacus is endemic for Australia.
Some scorpions in this family are kept in captivity in Australia (not Heteroscorpion).
No medical data have been found, but the members of this
family are probably of minor or no medical significance.

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)
