New occurrence records and updated global distribution of Limnias novemceras (Rotifera: Flosculariaceae) using citizen-contributed and published data

We report new occurrence records and an updated global distribution of Limnias novemceras Meksuwan, Jaturapruek & Maiphae, 2018 (Rotifera: Flosculariaceae) based on citizen-science observations and published data. Twenty-two records were compiled, 19 from social media, extending the species range from its presumed endemic area in southern Thailand to Nearctic, Neotropical, Afrotropical, Palearctic, Sino-Japanese, and Oriental realms. Morphological features were consistent across populations, while minor corona variation and ecological traits indicate behavioral flexibility.
