Urodacus manicatus, commonly known as the black rock scorpion, is a species of scorpion belonging to the subfamily Urodacinae (family Scorpionidae). It is native to eastern Australia. The black rock scorpion was described by Swedish naturalist Tamerlan Thorell in 1876 as Ioctonus manicatus. The type locality was described as "New Holland". In 1888 Reginald Innes Pocock, an assistant at the Natural History Museum in London, was cataloging specimens of the genus and described what he thought was a new species—naming it U. abruptus— from two dried female specimens, one from Adelaide and the other labelled "New Holland". German naturalist Karl Kraepelin concluded that Thorell's I. manicatus was the same species as U. abruptus and U. novaehollandiae. It was also collected from Cooma by William
