B33CB310FF883E51FF51FC59FB496227.taxon	discussion	Discussion: This species is known from only two female specimens, one collected in Kuranda QLD (Queensland), and one from Lamington National Park QLD. This widely disjunct distribution suggests that the species is present but rare across the east coast of Australia. Although no male has been collected, the holotype was successfully DNA barcoded, so if a male is collected in the future it can be confidently matched to the holotype using DNA evidence. The barcode data extracted from the holotype is publicly available on the BOLD website (process ID: SYCNC 805 - 18) and on Genbank (MK 073252), as detailed above in the Material and methods section.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FF8D3E54FF51FF54FD93637B.taxon	discussion	Discussion: This western species has been collected hilltopping on Mount Barker. The hilltop is dominated by dry sclerophyll forest and has a communications tower on it. The habitat around the hilltop is largely agricultural. Psilota alexanderi sp. nov. adults were all on an elevated rise just west of the communications array. This summit of the rise is rocky and open with Eucalyptus trees around the clearing. The flies were hovering about 3 – 4 m above the rocks along the edge of this clearing.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FF8D3E5AFF51F990FC5B61D3.taxon	etymology	Etymology: The specific epithet ‘ apiformis ’ consists of api-, which is the Latin for bee (‘ apis’), and - formis, the Latin for “ shape, figure, form, or appearance ” (‘ forma, - ae’). This is in reference to the bee-like appearance of Psilota apiformis, which may grant it some measure of protection from predators.

B33CB310FF863E5CFF51F968FBC563EB.taxon	etymology	Etymology: The specific epithet ‘ auripila ’ consists of auri -, derived from the Latin for “ gold ” or “ lustre ” (‘ aurum’), and - pila, derived from the scientific term “ pile ”, which refers to the hair-like structures covering some tergites in Syrphidae. This is in reference to the bright, pale pile on the face of Psilota auripila sp. nov. that distinguishes it from similar species, Psilota spathistyla sp. nov. and Psilota nigripila sp. nov.

B33CB310FFBB3E60FF51FAACFB1D6147.taxon	discussion	Discussion: This species was originally described from a female specimen collected in the Aru Islands Regency (Maluku Province, Indonesia). This lectotype female is in the BMNH and is labelled “ Orthonevra basalis, wlk ”, “ basalis ”, “ Holotype [red circular label] ”, “ Aru ”, and “ Jeff Skevington Specimen # 45632 ”. The last label as added by the author ADY as a unique identifier for databasing purposes. This specimen is herewith designated lectotype and has been so labelled. The above description is the first of the male of this species and the first record of this species in Australia. This male is assumed to be the conspecific with the Indonesian female lectotype due to the distinct brown vitta on the wing and the faint metallic blue markings on the abdomen, which match the lectotype very well.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FFB23E69FF51FAF5FB8F6323.taxon	discussion	Discussion: Lectotype female in MNHN and labeled: “ HOLOTYPE ” [red label], “ 13 / 44 ” [circular label], “ MNHN, Paris / ED 9367, ” and “ Psilota / coerulea / n. sp. Macq. ” Only a fragment remains in a microvial, along with a badly dermestid eaten remnant on the pin. The original species description of Psilota coerulea does not list a holotype or syntype series but appears to be based on a female specimen described as “ De le Tasmanie. Muséum. ”. A specimen in the Paris Muséum National d’Histoire Naturelle bears labels reading “ HOLOTYPE ” [red label], “ 13 / 44 ” [circular label], “ MNHN, Paris / ED 9367, ” and “ Psilota / coerulea / n. sp. Macq. ”, and appears to be the specimen that Macquart originally described. This specimen is herewith designated lectotype and has so been labeled. The specimen has been badly eaten by dermestids, with only parts of the thorax and a fragment in a genitalia vial remaining. Likewise, the original description of Merodon muscaeformis is based on a female in BMNH and labeled “ Type ” [green circular label], “ Muscae, ” “ VDL [Van Dieman’s Land] ” and “ Merodon / muscaeformis / Wlk ” [in E. E. Austen’s handwriting]. This specimen is herewith designated lectotype and has been so labeled.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FFB03E6DFF51F968FDEE6289.taxon	discussion	Discussion: Psilota cuprea doubtlessly encompasses multiple species as described here. Initial DNA barcode analysis indicates that at least nine species are represented (Figure 43). Further DNA barcoding and male genitalia dissection are required to adequately separate the full range of specimens into species and will be tackled in a future revision. Furthermore, there are several other species of Psilota described from Australia that may or may not be synonyms of P. cuprea, including P. erythrogaster, P. rubra, and P. rubriventris (See ‘ species not here recognized’ below). Because it is impossible to tell what name should properly be assigned to different barcode clusters without a full revision of this complex, these species have not been treated individually. As mentioned in the introduction, an individual from this complex was reared from the “ rotten caudex of Xanthorrhoea resinosa ”. The holotype of this species was not available for study.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FFAA3E71FF51FB38FC5162AF.taxon	discussion	Discussion: Psilota femoralis displays more divergence in COI sequences than other Psilota and may represent a species complex. However, no morphological characters could be found to distinguish specimens that were more similar based on COI than others, and it was therefore treated as a single species. This species has been collected on Leptospermum blossoms. The holotype of this species was unavailable for study but identified material from various collections from across Australia match the original description well.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FFA43E7DFF51FF54FE476060.taxon	etymology	Etymology: The specific epithet ‘ nigripila ’ consists of nigri -, derived from the Latin for “ black ” or “ dark ” (‘ niger’), and - pila, derived from the scientific term “ pile ”, which refers to the hair-like structures covering some tergites in Syrphidae. This is in reference to the dark pile on the face of Psilota nigripila sp. nov. that distinguishes it and Psilota spathistyla sp. nov. from Psilota nitida.

This specimen is herewith designated lectotype and has so been labeled. Psilota nitida displays more divergence on COI than other Psilota and may represent a species complex. However, no morphological characters could be found to distinguish specimens that were more similar on COI than others, and it was therefore treated as a single species.

B33CB310FFDB3E06FF51F8DCFAD464DF.taxon	etymology	Etymology: The specific epithet pollinosa derives from “ pollinosity ”, the scientific term for the microtrichose hairs covering the cuticle of some body parts of Syrphidae. This is in reference to the pollinose pleuron of Psilota pollinosa sp. nov., which distinguishes it from Psilota coerulea, Psilota smaragdina sp. nov., and Psilota alexanderi sp. nov.

B33CB310FFDF3E06FF51FDCCFED462A9.taxon	discussion	Discussion: This species possesses several characters unusual for Psilota, including the hook-shaped inner lobe of the male surstylus, the tubercle on tergite 3, and the bare face. Preliminary evidence based on COI suggests that it is simply a highly apomorphic species of Psilota. This can be tested in future using multiple genes if fresh material is obtained.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FFD23E09FF51FAF5FD446783.taxon	discussion	Discussion: This species has been collected on Leptospermum (Myrtaceae) blossoms. A female specimen was observed ovipositing on the trunk of a Fraxinus angustifolia subsp. oxycarpa (Claret or Caucasian Ash) in Tasmania (Fig. 67). As this tree species is not native to Australia, it likely indicates that P. solata is not species-specific in its larval habitat. However, without successfully rearing larvae out of the tree, it is impossible to say for certain that the larvae can successfully develop in Fraxinus.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FFD43E15FF51FF54FA5061B7.taxon	discussion	Discussion: Psilota tristis doubtlessly encompasses multiple species as described here. Initial DNA barcode analysis indicate that at least 23 species are represented. Further DNA barcoding and male genitalia dissection is required to adequately separate the full range of specimens into species and will be discussed in a future revision. Furthermore, there are several other species of Psilota described from Australia that may or may not be synonyms of P. tristis, including Psilota hirta, Psilota shannoni, and Psilota queenslandica (see ‘ species not here recognized’ below). Finally, the type specimens of P. tristis, P. queenslandica, and P. hirta were deposited in Venezuela and were unavailable for study at the time of this publication. Because it is impossible to tell what name should properly be assigned to different Barcode identities without a full revision of this complex, these species have not been treated individually.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FFC23E18FF51FE74FC57619B.taxon	discussion	Discussion: There are five specimens labeled as syntypes in the Macquart collection of the MNHN but none of these specimens actually are syntypes, as Macquart clearly stated in his original description that it was based upon female (s) in the Bigot collection. Today there is a single female in Oxford from the Bigot collection labeled: “ Psilota / viridis / n. sp. Macq. / ♀ / Nov. Holl. / D. exot. nov. / Holotype / P. viridis EX COLL. BIGOT / Jeff _ Skevington _ Specimen 45697 ”. This label is of the standard kind used by Bigot (see for example, figure 7 in Thompson (1988 )), with the final three labels later added by curators and the author ADY as a unique identifier label for databasing purposes. This specimen is herewith designated lectotype and has so been labeled.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.

B33CB310FFC13E1EFF51FAF0FC396433.taxon	etymology	Etymology: The specific epithet ‘ xanthostoma ’ consists of xantho, derived from the Latin “ xanthous ”, meaning “ yellow ”, and stoma, meaning “ hole ”, or mouth. This is in reference to the yellow face, gena, and “ mouth ” area of P. xanthostoma sp. nov.

B33CB310FFC13E1EFF51FAF0FC396433.taxon	discussion	Discussion: This species is known from a single female specimen, collected on Mt. Moffat in Carnarvon National park, Queensland. Although no male has been collected, a fragment of the DNA barcode was successfully obtained from the holotype, so if a male is collected in the future it can be confidently matched to the holotype using DNA evidence. The barcode data extracted from the holotype is publicly available on the BOLD website (Process ID: SYRAU 381 - 18), as detailed above in the Materials and methods section.	en	Young, Andrew D., Skevington, Jeffrey H., Steenis, Wouter Van (2020): Revision of the Psilota Meigen, 1822 flower flies (Diptera: Syrphidae) of Australia.
