The aspidiotine scale insect genus Morganella, which has been composed of some species from separate parts of the world in addition to the widely distributed type species, is revised and restricted to three species: M. longispina, the type species; M. polyctena, a species recently described from the Philippines; and M. barbatissima, sp. nov., found on Cyathostemma excelsa in Malaya. Thus recomposed, the genus is native to eastern Asia, and the type species should have originated in this region. Suluaspis rhizophorae, gen. et sp. nov., associated with the mangrove Rhizophora apiculata, and Acanthaspidiotus hibisci, sp. nov., associated with the littoral plant Hibiscus tiliaceus, are described from the Philippines. Both Suluaspis and Acanthaspidiotus are similar to Morganella in having thickened marginal setae on the pygidium. Suluaspis possibly has some relationship to Morganella, whereas Acanthaspidiotus may not be closely related to Morganella.
