First records of the gall midge genus <i>Pseudasphondylia</i> Monzen, 1955 (Diptera: Cecidomyiidae) from Australia

Abstract Two new species of Pseudasphondylia Monzen, 1955 are described and are the first records of this genus in Australia and for the plant families Myrtaceae and Chenopodiaceae. Pseudasphondylia melanopileus sp. nov. forms inconspicuous galls on the fruits of Melaleuca ericifolia (Myrtaceae) in southern Victoria. Pseudasphondylia nitrariaceia sp. nov. causes semi‐woody galls on the inflorescences of Chenopodium nitrariaceum (Chenopodiaceae) and is widespread in low‐rainfall regions of south‐eastern Australia. Descriptions of adults and immature stages and DNA sequences of the cytochrome oxidase unit I mitochondrial gene segment are given for each of the new species.
