Abstract
A new, peculiar genus and species, Capillantennatus mirabilis gen. et sp. nov., is described and illustrated based on a series of four males collected in Kai Besar Island, Maluku, Indonesia. To our knowledge it is the first known genus of Clavigeritae with antennae that bear trichomes for myrmecophily. The antennal morphology and biogeography of Clavigeritae in the Indo-Australian Archipelago are briefly discussed. A list of all known species from the Indo-Australian Archipelago is provided.
