Abstract

Background: The genus Conotalopia Iredale, 1929 consisting of marine trochids, primarily inhabits the intertidal zone. Globally, eight recent species have been documented, all of which occur in the Pacific Region. The genus has not previously been recorded from Chinese seas.

New information: This study fills a knowledge gap by reporting, for the first time, the presence of the trochid genus Conotalopia Iredale, 1929 in China. Specifically, Conotalopiasematensis (Oyama, 1942) was detailed using morphological characteristics derived from the shell (Fig. 1A-F and H-I), operculum (Fig. 1G) and radula (Fig. 1J-L). Additionally, this study introduces comprehensive scanning electron microscope illustrations and molecular data, contributing valuable taxonomic information for the first time.

Keywords: micromolluscs; morphology; new record; systematics.
