Takagi, S. 2021 Further forms of Rutherfordia, with particular reference to the second-instar males (Sternorrhyncha: Coccoidea: Diaspididae).. Insecta Matsumurana (New Series) 77: 17-65

Notes: Ten new forms or species of scale insects are described from Malaysia as members of the genus Rutherfordia MacGillivray. Five of them are formally named, and the other five are treated under temporary names. They are referred to the genus on account of their possession of two unusual characters in the adult females. They are far from uniform in other characters of the adult females, and are diverse also in the second-instar males and even in the first-instar nymphs.
