Abstract
Myrmozercon burwelli sp. nov. is described from arboreal nests of Polyrhachis flavibasis (Formicidae) from rainforests in southeast Queensland, Australia. Myrmozercon beardae sp. nov. is described from unknown ants from South Australia. New specimens with host species data are recorded for Myrmozercon iainkayi Walter, and its protonymph and deutonymph are described. Supplementary notes are provided for the North American M. rotundiscutum Rosario & Hunter. The genus diagnosis is modified and its limits discussed. A revised key to Australian Myrmozercon is provided. Parabisternalis and Laelaspulus are synonymised with Myrmozercon. Laelaps flexuosa Michael is confirmed as a species of Myrmozercon.References
