Despite the importance of clearly assessing the distribution boundaries of species, it is not possible for scientists to acquire genetic information and conduct molecular analysis for all populations. Consequently, citizen science is of increasing importance for large scale data collection. In this study, we described the range boundaries of the four Hynobius species occurring in Korea based on genetic identification and refined their distribution through citizen science data. The genetic identification of individuals was extracted from the literature, while the citizen science data were extracted from iNaturalist through GBIF. Distribution boundary lines were drawn from the genetic data and consistency with citizen science datapoints was assessed through a comparative analysis with the points found beyond the established boundary lines. Depending on the species, 1.43 to 25.00% of the observations extracted from the citizen science data were located beyond the boundaries suggested by the molecular analyses, with average distances ranging from 3.51 ± 2.97 to 51.47 ± 30.87 km (mean ± SD). We considered these variations negligible in the view of the whole distribution of these species. In general, the distributions extracted from iNaturalist were accurate and adequately representative of the distribution of the species, with the exception of the recently split H. quelpaertensis. Additionally, citizen science data highlighted the absence of gaps in the distribution of these species. In conclusion, given the good accuracy of citizen science data, we recommend the publication of molecular based data so that citizen science platforms could help define accurately the range of species for which data is missing or outdated.

Funding Information:
The data collected for this project was downloaded from, an open-access database, such as defined in the Memorandum of Understanding on GBIF, paragraph 8. Data were not downloaded from iNatural-ist directly as it does not provide a DOI for the dataset, unlike GBIF. This work was supported by a research grant from the Rural Development Administration (PJ012285) to YJ, and by a grant from the National Research Foundation of Korea (NRF) funded by the Ministry of Education (NRF-2016R1D1A1B03934071) to MSM.
