03FF4B47FFB8FF8EFF2EFAD8FEAD6E9C.taxon	materials_examined	Type material: Holotype. ♂ (VAIC # 085802, Figs 1 A, B), Australia, Victoria, Watsonia, 09 - V- 2024, ex Dahlia sp. (Asteraceae), coll. Janice Wong. Paratypes. 4 ♂♂ (VAIC # 085803 – 085806) and 4 ♀♀ (VAIC # 085809 - 085812), same data as holotype; 4 ♂♂ and 2 ♀♀ (NWAFU), same locality data as holotype, 29 - III- 2024. Additionally, over 400 adult and nymphal specimens collected from the same location and individual Dahlia sp. plant at different times; 29 - III- 2024, 02 - IV- 2024, and 01 - V- 2024 (in VAIC). Molecular data: Seven specimens were used to obtain COI barcodes following Eow et al. (2023): four specimens destructively DNA extracted (2 x nymphs and 2 x females), and three non-destructively DNA extracted (males). We found five different haplotypes which diverged by up to 0.8 % (GenBank accession numbers: PV 138852 - 138856). The COI barcode sequences were compared to barcode sequences from the BOLD database (Barcode of Life Data System), and seven reference sequences with> 97 % similarity matches were found. Five of these records have publicly available collection details, indicating the same taxon has also been found in Madang, Papua New Guinea in 2016 (GMNGZ 125 - 16), South Australia, Australia in 2022 (ASMIJ 22720 - 24), and Queensland, Australia from 2012 - 2024 (HEQT 1099 - 12, GCQT 574 - 17, AUCGP 278 - 24, AUCGP 279 - 24). The host plant information is not known for these records.	en	Wang, Ran, Selleck, Cait, Zhang, Yalin, Cao, Yanghui (2025): Taxonomy of the leafhopper genus Distantasca (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini) with description of a new species from Australia.

03FF4B47FFB8FF8EFF2EFAD8FEAD6E9C.taxon	etymology	Etymology. The species epithet is derived from the combination of “ para- ” and “ smithi ” which refers to the similarity of this new species to D. smithi (Fletcher & Donaldson, 1992).	en	Wang, Ran, Selleck, Cait, Zhang, Yalin, Cao, Yanghui (2025): Taxonomy of the leafhopper genus Distantasca (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini) with description of a new species from Australia. Zootaxa 5666 (4): 594-600, DOI: 10.11646/zootaxa.5666.4.10, URL: http://dx.doi.org/10.11646/zootaxa.5360.3.8
03FF4B47FFB8FF8EFF2EFAD8FEAD6E9C.taxon	discussion	Remarks. This new species is similar to D. smithi (Fletcher & Donaldson) in the structures of pygofer ventral appendages, subgenital plate and anal tube appendages. However, it can be distinguished from D. smithi by the feature that the aedeagus has only one basal process (D. smithi has a pair of aedeagal processes). Additionally, D. parasmithi is currently only recorded from Dahlia, while D. smithi is a known pest of citrus in Australia.	en	Wang, Ran, Selleck, Cait, Zhang, Yalin, Cao, Yanghui (2025): Taxonomy of the leafhopper genus Distantasca (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini) with description of a new species from Australia.
