Abstract
The genus Therea Billberg, 1820 is redefined as a monophyletic taxon b elonging to the group Ergaula + Eucorydia + Therea + Cryptocercus in t he subfamily Polyphaginae Kirby, 1904. Three new species, T. regularis , T. defranceschii, and T. hyperguttata, are described as well as T. p etiveriana (Linnaeus, 1758) and T nuptialis (Gerstaecker, 1861). The k nown distribution of the genus in India extends from dry deciduous for ests to more humid formations (between latitudes 19 and 10-degrees N). The species live in areas with mean annual rainfall ranging from 500 to 3800 mm.
