Background:
Hainan Island serves as an important reservoir of molluscan biodiversity in China. However, the documented molluscan fauna is predominantly composed of macromolluscan species, while micromolluscan diversity remains critically understudied.
New Information:
In this study, we document four marine microgastropod species belonging to the family Zebinidae Coan, 1964 from Hainan Island, China: Schwartziella triticea (Pease, 1861), Pandalosia subfirmata (O. Boettger, 1887), Zebina tridentata (Michaud, 1830) and Stosicia annulata (Dunker, 1860). Scanning electron microscopy (SEM) was employed to examine shell morphology. Amongst these, Stosicia annulata (Dunker, 1860) represent a new record for China, suggesting that more extensive sampling along Hainan Island's coastline will likely yield additional discoveries.
