Following extensive fieldwork over two decades, detailed studies of both Australian and European herbaria and consideration of both crucial contributions by citizen scientists and social media observations, nine species of the <i>D. microphylla</i> complex are here described and illustrated, including four new species: <i>D. atrata</i>, <i>D. hortiorum</i>, <i>D. koikyennuruff</i>, and <i>D. reflexa</i>.
