Bottom Line: Three new species of Pipinnipons are described, increasing the total number of species to five: Pipinnipons chauncyvallissp. n., Pipinnipons fascipennis (Kröber), Pipinnipons kampmeieraesp. n., Pipinnipons kroeberi Winterton, and P. sphecodasp. n.Pipinnipons and Acupalpa are rediagnosed in light of the new species presented herein and revised keys to species are included.A dichotomous key to genera of Australasian Therevidae is included.As an empirical example of cybertaxonomy, taxonomic descriptions were composed using a character matrix developed in Lucid Builder (in Structured Descriptive Data (SDD) format) to generate natural language descriptions supplemented by online specimen and image databases.

ABSTRACT
Australian stiletto flies of the sister-genera Acupalpa Kröber, 1912 and Pipinnipons Winterton, 2001 (Diptera: Therevidae: Agapophytinae) are revised. Twelve new species of Acupalpa are described, while Acupalpa imitans (White, 1915), comb. n. is transferred from Pipinnipons and Acupalpa albimanis (Kröber, 1914), comb. n. is transferred from Ectinorhynchus Macquart as a senior synonym of Acupalpa pollinosa Mann. The total number of species of Acupalpa is therefore increased to 19: Acupalpa albimanis (Kröber), comb. n., Acupalpa albitarsa Mann, Acupalpa bohartisp. n., Acupalpa divisa (Walker), Acupalpa dolichorhynchasp. n., Acupalpa glossasp. n., Acupalpa imitans (White), comb. n., Acupalpa irwini Winterton, Acupalpa melanophaeossp. n.,Acupalpa miaboolyasp. n., Acupalpa minutasp. n., Acupalpa minutoidessp. n., Acupalpa notomelassp. n., Acupalpa novayamarnasp. n., Acupalpa rostrata Kröber, Acupalpa semirufa Mann, Acupalpa westralicasp. n., Acupalpa yalgoosp. n. and Acupalpa yanchepsp. n. Three new species of Pipinnipons are described, increasing the total number of species to five: Pipinnipons chauncyvallissp. n., Pipinnipons fascipennis (Kröber), Pipinnipons kampmeieraesp. n., Pipinnipons kroeberi Winterton, and P. sphecodasp. n.Pipinnipons and Acupalpa are rediagnosed in light of the new species presented herein and revised keys to species are included. A dichotomous key to genera of Australasian Therevidae is included. As an empirical example of cybertaxonomy, taxonomic descriptions were composed using a character matrix developed in Lucid Builder (in Structured Descriptive Data (SDD) format) to generate natural language descriptions supplemented by online specimen and image databases. Web resources are provided throughout the document including: a) links to high resolution colour images of all species on Morphbank, b) registration of authors, publications, taxon names and other nomenclatural acts in Zoobank, with assignment of Life Science Identifiers (LSIDs) for each, c) links to Genbank accession records for DNA sequences, and d) assignment of LSIDs to specimen records with links to respective records in an online Therevidae specimen database.
