Two new species of Cameronaspis, C. dilleniae occurring on Dillenia sp. and C. ilicis on Ilex revoluta, are described from high altitudes on Mt. Kinabalu, Sabah (Borneo Is.), Malaysia, and C. adinandrae is recorded from Sabah and Nepal and from Adinandra sp., Vernonia arborea, and Eurya acuminata. The known species of Cameronaspis are revised, and their status as species is discussed. Two new genera are proposed, based on two new species: Kuchingaspis hopeae occurring on Hopea sp. at Kuching, Sarawak (Borneo Is.), and Larutaspis lithocarpi associated with Lithocarpus wallichianus on Bukit Larut, Malaya. Pinnaspis megaloba Takahashi, 1942, is transferred to Larutaspis on the basis of the original description. Another species was collected in association with Kuchingaspis hopeae, and is tentatively placed in Chionandaspis, but it is not formally named. All the genera treated in this paper belong to the subtribe Chionaspidina, and are similar in the median trullae prominent and set close, appressed together, or fused together and the second trullae reduced to very small pointed processes in the adult female. They distinctly differ in some other details, and may not be closely related to each other in spite of the similarlty, which should involve convergence and/or parallelism.
