Ulucoccus gombakensis and U. danumensis are recorded from Sarawak and Luzon, respectively. Some characters are variable in the adult female of U. danumensis and local forms are recognized. The two species are remarkably different in the first instar in spite of the similar adult females. The significance of Ulucoccus, a supposedly primitive relict, is mentioned in connection with polymorphism of the second instar larva of the family Diaspididae.
