Correction on: Feng Leyuan, Zhang Shiyan, Tao Ming, Sun Ting*, Wang Antai. Two new species of Plagiostomum (Prolecithophora, Plagiostomidae) from China with its morphology, phylogeny, and reproductive strategy. Frontiers in Marine Science, 2025Science, , 12: 1520497. doi: 10.3389/fmars.2025.1520497 .1520497 There was a mistake in figure 6 as published. In the phylogenetic tree, the original species names Plagiostomum nanhaiensis and Plagiostomum plagae should be changed to Plagiostomum nanhaiense and Plagiostomum plagum. The corrected figure 6 appears below. Corrected the species names.In the abstract, [Morphologically, Plagiostomum nanhaiensis sp. nov. can be distinguished from congeneric species by its three dark brown dorsal stripes, pear-shaped vesicula seminalis located ventrally to the intestine, and the testes surrounding the ovaries and bead-like sperm. Additionally, Plagiostomum plagae sp. nov. can be distinguished from P. nanhaiensis sp. nov. and other congeneric species by its two connected dorsal stripes, multiple spherical testes arranged along the ventral midline, a hemispherical vesicula seminalis located on the right ventral side, and grain-shaped sperm. Kimura's two-parameter distance and phylogenetic analyses further support the recognition of these two new species, showing that the three specimens of P. nanhaiensis sp. nov. and P. plagae sp. nov. form two separate clades within Plagiostomum with solid support.] This has been corrected to read:[Morphologically, Plagiostomum nanhaiense Feng, Sun & Wang, sp. nov. can be distinguished from congeneric species by its three dark brown dorsal stripes, pear-shaped vesicula seminalis located ventrally to the intestine, and the testes surrounding the ovaries and bead-like sperm. Additionally, Plagiostomum plagum Feng, Sun & Wang, sp. nov. can be distinguished from P. nanhaiense sp. nov. and other congeneric species by its two connected dorsal stripes, multiple spherical testes arranged along the ventral midline, a hemispherical vesicula seminalis located on the right ventral side, and grain-shaped sperm. Kimura's two-parameter distance and phylogenetic analyses further support the recognition of these two new species, showing that the three specimens of P. nanhaiense sp. A correction has been made to the section [2 Materials and methods, 2.5 Sex allocation experiment and paraffin sections, Paragraph 1]: "[To study the reproduction of the new species, 12 single-individual cultured groups, 10 three-individual cultured groups, and a population cultured group were established. Mature flatworms (larger than 600 μm in length) in the single-individual cultures were reared in six-well cell culture plates (well diameter 35 mm). The three individual cultured groups were conducted on a small scale in 90-mm glass evaporation dishes, while the population cultured group consisted of 200-300 mature flatworms in a 10-cm-diameter round buckle box. Habitat water and food were supplied daily. Flatworms at different cultured stages were fixed using Bouin's fluid and then washed and soaked in 75% ethanol until the epidermis was transparent and the shadow of the copulatory apparatus was visible. The presence or absence of male copulatory apparatus was examined under an Olympus SZX16 stereomicroscope. Paraffin tissue sections were then prepared to observe the changes in the copulatory apparatus according to Yang et al. (2020). Additionally, 60 sexually mature flatworms freshly collected from the habitat were used as controls. All type specimens were deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS).]" A correction has been made to the section [3 Results, 3.1.2 Plagiostomum plagae sp. nov., Paragraph 3]: "[Etymology. The epithet "plagum" is derived from the Latin word "plaga", meaning "stripe", which refers to the two prominent stripes on the dorsal surface of this species.]" In addition to the modifications listed above, the only remaining changes needed are to update the names of two species throughout the article: replace Plagiostomum nanhaiensis (or P. nanhaiensis) with Plagiostomum nanhaiense (or P. nanhaiense), and Plagiostomum plagae (or P. plagae) with Plagiostomum plagum (or P. plagum). Since these names appear in nearly every paragraph, listing each instance would be unnecessarily tedious. For efficiency, you may perform a global search to replace 'nanhaiensis' with 'nanhaiense,' and likewise replace 'plagae' with 'plagum'. However, if you would prefer a detailed line-by-line revision, please let me know, and I will provide it.
