Abstract - The findings reported here contribute to what is currently known about the geographical distribution, host range and reproduction of the ectoparasitic mite, Varroa underwoodi. Female V underwoodi and their nymphal offspring were collected from sealed drone cells in Apis cerana colonies in Papua New Guinea (PNG), the Indonesian provinces of Java, Sulawesi and Irian Jaya, and the Indonesian islands of Biak and Yapen. Gravid female V underwoodi were also collected from newly capped drone cells in A nigrocincta colonies in Sulawesi. Adult female V underwoodi, showing no signs of reproduction, were collected from capped worker cells in A mellifera colonies in PNG. On the basis of morphological structures, the adult female V underwoodi specimens from PNG and Indonesia were indistinguishable from V underwoodi specimens described from other localities.
