Review of the seven new species of Isometopinae (Heteroptera: Miridae) in Australia and discussion of distribution and host plant associations of the subfamily on a worldwide basis

The Isometopinae are a poorly known subfamily of Miridae (Heteroptera) with 42 genera and 239 described species worldwide. Prior to this study, the subfamily was represented in Australia by a single species, Eurocrypha thanatochlamus. In this work, three isometopine genera, Jozefus, Paratopus and Myiomma, are reported from Australia for the first time, and Australotopus gen. nov. is described as new to science. The following seven new species are described: Australotopus cooperensis sp. nov., Jozefus brunetus sp. nov., Jozefus monteithi sp. nov., Myiomma albalata sp. nov., Myiomma basseti sp. nov., Paratopus brunocapitus sp. nov. and Paratopus flavocapitus sp. nov. Habitus images, scanning electron micrographs, measurements and illustration of male and female genitalia are provided to support the diagnoses of the above taxa. The distribution and plant associations of the subfamily Isometopinae are discussed.
