摘要： The genus Siphonaria is a group of limpet-shaped pulmonates living on intertidal rocks along the Chinese coast. Due to the fluctuating intertidal environment, the morphological characteristics of Siphonaria shells are reshaped, resulting in morphologically divergent evolution within species and inaccuracy of taxonomic identification without molecular evidence. Large-scale identifications on Siphonaria animals combining morphological and molecular evidence are considerably absent. In this study, we sampled 245 Siphonaria specimens along the coast of China (from Guangxi to Shandong) and conducted the identification based on morphological characteristics and DNA barcoding data including 16S ribosomal RNA, 12S ribosomal RNA, Cytochrome c oxidase subunit I, and Histone 3. The results indicated five Siphonaria species, i.e., Siphonaria japonica Donovan, 1824; Siphonaria sirius Pilsbry, 1894; Siphonaria atra Quoy & Gaimard, 1833; and two new species (Siphonaria petasus sp. nov. and Siphonaria floslamellosa sp. nov., Zang, Ma & Wang). We conducted a detailed comparison of these species and found many morphological differences, with the most distinctive differences being the radial ribs and siphonal ridge. We created a new identification key based on these features, providing new insights into the phylogeny and taxonomy of the genus Siphonaria. In addition, the divergence time indicated that species of the Siphonaria genus underwent rapid diversification during the late Pliocene to Pleistocene (3.46-1.53 Mya), with climate likely being an important driver of this diversification.
