Achilus is the type genus of planthoppers of the family Achilidae. This may be a monotypic genus containing the type species Achilus flammeus.<small>Kirby, 1818</small>: which is the "red fingernail bug" and found in Australia. The placement of A. cixioides <small>Spinola</small> from Chile, is uncertain, but it may belong in Mnemosyne <small>StÃÂ¥l, 1866</small> (Cixiinae}. The genus described by William Kirby in 1819.
