A new species of Mycetophilidae, Cordyla australica sp. n., is described from continental Australia and
Tasmania, representing the first Cordyla record in the region. A detailed description of its morphology
with illustrations of male and female terminalia and a map of the collecting localities are provided. According
to the structure of male terminalia, C. australica sp. n. belongs to the C. murina species-group
that has 13 species worldwide. Within the group C. australica sp. n. resembles C. murina but has a unique
outline of the hypoproct and medial branch of the gonostylus. The observed distributional pattern is
restricted to the rainforest of eastern Australia and Tasmania.
