Ahead of DNA Examination, the taxonomy with the widow spider genus Latrodectus had been unclear—variations in the quantity of species mirror the difficulty of working with morphology to determine subdivisions in the genus.[10] Substantial interest inside their systematics was most probably prompted with the professional medical significance of these venomous spiders.[10] Swedish arachnologist Tamerlan Thorell described the redback spider in 1870[eleven] from specimens gathered in Rockhampton and Bowen in central Queensland.
