Abstract
The pseudoscorpion genus Indohya Beier, 1974 is known to occur in three Gondwanan fragments around the Indian Ocean – southern India, Madagascar and north-western Australia – suggesting that the genus had evolved prior to the breakup of Gondwana and was present on each landmass as they rifted apart during the Mesozoic. The Australian fauna is the most diverse, with nine species previously described from Cape Range and the Kimberley region of north-western Australia. The present study documents the genus Indohya in Australia using a combination of morphology and DNA sequence data. We found a total of 36 species, including 27 new species. The majority of the Pilbara fauna consist of blind troglobites collected from subterranean ecosystems, with an additional three eyed species from epigean habitats. The new species consist of one from Cape Range (I. anastomosa Harvey & Burger, n. sp.), 21 from the Pilbara (I. adlardi Harvey & Burger, n. sp., I. alexanderi Harvey & Burger, n. sp., I. aphana Harvey & Burger, n. sp., I. aquila Harvey & Burger, n. sp., I. arcana Harvey & Burger, n. sp., I. arnoldstrongi Harvey & Burger, n. sp., I. boltoni Harvey & Burger, n. sp., I. cardo Harvey & Burger, n. sp., I. catherineae Harvey & Burger, n. sp., I. cockingi Harvey & Burger, n. sp., I. cribbi Harvey & Burger, n. sp., I. draconis Harvey & Burger, n. sp., I. furtiva Harvey & Burger, n. sp., I. incomperta Harvey & Burger, n. sp., I. jessicae Harvey & Burger, n. sp., I. lynbeazlyeae Harvey & Burger, n. sp., I. morganstrongi Harvey & Burger, n. sp., I. rixi Harvey & Burger, n. sp., I. sagmata Harvey & Burger, n. sp., I. scanloni Harvey & Burger, n. sp. and I. silenda Harvey & Burger, n. sp.) and five from the Kimberley (I. currani Harvey & Burger, n. sp., I. finitima Harvey & Burger, n. sp., I. julianneae Harvey & Burger, n. sp., I. karenae Harvey & Burger, n. sp. and I. sachsei Harvey & Burger, n. sp.). The study is augmented with sequence data from 29 species of Indohya, including all of the 24 species recorded from the Pilbara and Cape Range, and five of the 12 known Kimberley species. Seven clades recovered during the molecular analysis are only represented by nymphs, but we used COI sequence data to diagnose these species in the absence of adult morphological data.

Description of the data and file structure
This dataset is associated with Harvey et al. 2023 (https://doi.org/10.11646/zootaxa.5342.1). The three FASTA files contain DNA sequence data for different genetic markers used in molecular biology and phylogenetics.
It contains four items.
Table_S1__COI.fasta
Table_S2__18S.fasta
Table_S3__28S.fasta
Table_S4__COI_pairwise.xlsx
The first three are Alignment files for the molecular markers COI, 18S, and 28S, which were used to generate the molecular phylogeny for the study.
The fourth is a COI pairwise distance table for the mitochondrial gene COI.
The alignment files were aligned using the MAFFT version 7.490 (Katoh et al. 2002; Katoh & Standley 2013) plug-in withinthe Geneious software package (Biomatters Ltd; https://www.geneious.com/, accessed June 2021 with the default settings.
COI (Cytochrome c oxidase subunit I) is a mitochondrial gene widely used in DNA barcoding because it evolves relatively quickly and helps distinguish closely related species.
18S rRNA and 28S rRNA are nuclear ribosomal RNA genes that evolve more slowly, making them useful for studying deeper evolutionary relationships among species and higher taxonomic groups.
Table_S4__COI_pairwise.xlsx
- Each row and column represents a specimen (identified by its WAMT registration number) belonging to a taxon (e.g., Hya minuta).
- The numbers (e.g., 99.7, 80.1, 75.6) show the percentage similarity between two DNA sequences.
