Despite long years of taxonomic research on Eulimidae in Japan, their local species richness remains to be investigated, and few studies have focused on a eulimid fauna of a certain echinoderm taxon, even if it is a common species. Here, we conducted a comprehensive sampling of Melanella species parasitizing the black sea cucumber Holothuria leucospilota in Shirahama, Wakayama, central Japan. The data used in this study were partly obtained during a summer education program of the Seto Marine Biological Laboratory, Kyoto University. Melanella kuronamako and M. spina parasitized the external surface, and two unidentified species were found inside the host's body cavity. This study represents the first record of M. spina in Japanese waters and eulimids exploiting the internal habitat of H. leucospilota. Morphological and molecular comparisons between the present four species and other Japanese Melanella specimens suggested that they generally exhibit wide geographic distributions and low host specificity. Additionally, the two species from the body cavity were probably seldom observed in central Japan, as inferred from the accumulated results of the dissection of H. leucospilota through a long-running, annual education program at Shirahama.<\/jats:p>","DOI":"10.2108\/zs250003","type":"journal-article","created":{"date-parts":[[2025,6,17]],"date-time":"2025-06-17T03:41:07Z","timestamp":1750131667000},"page":"417-424","source":"Crossref","is-referenced-by-count":1,"title":["Co-Occurrence
