Abstract: Howickia Richards is the largest and most commonly collected genus of sphaerocerid fly in Australia, including a total of 44 described and undescribed species. Almost half of these species are wingless, with many originally placed in separate, often monotypic genera. However, these genera were described based on autapomorphies, which do not provide information regarding their relationships to other taxa. Examination of the genitalia of these species shows a unique synapomorphy with the other known species of Howickia, and therefore the genera Apterobiroina Papp, Australimosina Papp, Bentrovata Richards, Monteithiana Richards, Popondetta Richards, and Otwayia Richards are treated here as new synonyms of Howickia. Redescriptions for all 23 described species in Howickia and the newly synonymized genera, as well as descriptions of 21 new species are presented. A morphological phylogeny for the genus is also provided.
