Australian millipede assassins (Heteroptera: Reduviidae): Malingeus tumidus gen. et sp. nov. and Yaramayahus rufescens gen. et sp. nov., with new generic synonyms and an updated key

Malingeus tumidus gen. et sp. nov., a new millipede assassin from Queensland, and Yaramayahus rufescens gen. et sp. nov., a new millipede assassin from New South Wales, are herein described from the tribe Ectrichodiini (Ectrichodiinae). Additionally, Caloundranius formosus Miller, 1957, syn. nov. is here considered a junior synonym of Mendola puellula Breddin, 1900, which relegates the genus Caloundranius Miller, 1957, syn. nov. to a junior synonym of Mendola Breddin, 1900. The previously proposed status of Tasmanocoris evansi Miller, 1952, as a junior synonym of Nebriscus pupus Bergroth, 1895, is corroborated. Brisbanocoris fuscipennis Miller, 1957, syn. nov. is here considered a junior synonym of Lyramna vigil Breddin, 1900, which relegates the genus Brisbanocoris Miller, 1957, syn. nov. to a junior synonym of Lyramna Breddin, 1900. Finally, an updated generic key to the ectrichodiine genera of Australia is presented.
