Data from ‘Arthropod-associated leeches (Annelida: Hirudinida) of the World: Diversity, taxonomic reappraisal, ecological classification of host associations, and convergent evolution’

This dataset contains datasets from our review paper entitled “Arthropod-associated leeches (Annelida: Hirudinida) of the World: Diversity, taxonomic reappraisal, ecological classification of host associations, and convergent evolution” (Ecologica Montenegrina 89: 38-87 (2025); https://doi.org/10.37828/em.2025.89.3). Dataset S1. Taxonomic diversity and hosts of arthropod-associated leeches of the World (only non-predatory interactions were included). Dataset S2. Georeferenced occurrences of leech-arthropod associations in the World. Dataset S3. Records of leeches in the genera Paraclepsis Harding, 1924 and Palaemobdella gen. nov. (Glossiphoniidae). Dataset S4. Measurements and DNA/iDNA sequence numbers of the type series of Paraclepsis dongnaiensis sp. nov.
