Takagi, S. 1995a An approach to the Rugaspidiotini-problem [Homoptera: Coccoidea: Diaspididae].. Insecta Matsumurana (New Series) 52: 21-79.

Notes: Five genera and six species of armoured scale insects were examined in connection with a pending problem concerning the composition of the tribe Rugaspidiotini; emphasis on characters of the first instar; the results strengthen a previous supposition that the tribe is an assemblage of unrelated genera; Nimbaspis molardi and Natalaspis are revised; Anaimalaia scabra, new sp., new gen, is described from South India as occurring on Pterospermum and Amphisoma erectum; Galeomytilus obesus, new gen., new sp. is described from Palawan Is., the Philippines, on Colona.
