Description of two new species of the genus <i>Trochus</i> Linnaeus, 1758 (Gastropoda, Trochidae) from the South China Sea.

ABSTRACT: Two new species of the gastropod family Trochidae, Trochus nanhai sp. nov. and Trochus parvus sp. nov., are described from the South China Sea. Morphological comparisons and species delimitation analyses based on molecular phylogeny support the distinctiveness of the two species. Trochus nanhai sp. nov. exhibits substantial variation in shell morphology, which increases the difficulty of morphological characterization. Nevertheless, it can be distinguished by diagnostic characters such as the presence and arrangement of pustules along the suture of each whorl. Additionally, multiple species delimitation methods (ASAP, ABGD, bPTP and GMYC) revealed potential taxonomic inconsistencies within previously identified Trochus species. To assist vis
