Limnichthys koreanus, a new species of creediid fish from South Korea (Teleostei: Acropomatiformes: Creediidae)
Body elongated; cylindrical and posteriorly compressed. Head to body slope almost flat; Eyes on dorsal of head, large, and bulging. Snout terminal; upper jaw projects more than lower jaw; upper and lower jaws with a single row of minute conical teeth; a pair of filament-like antennas on anterior upper jaw (or absent); cirri on lower jaw; lips fleshy; vomer with well-developed conical teeth; palatine teeth absent; pharyngeal teeth present; tongue slender and pointed. A single of median interorbital sensory pore; Dorsal fin rays 25–27; anterior of dorsal fin remaining of 3–4th anal fin ray; posterior of dorsal and anal fin reaching precaudal (free from caudal). Anus behind half of body. Anal fin rays 26–28; anal fin length uniform. Caudal peduncle length very short. All fin rays not branched (only caudal fin branched). Lateral line scales 42–46; lateral line scales trilobed.

Project Data
Limnichthys koreanus sp. nov. is described on the basis of the holotype and eleven paratypes from subtidal waters of Seogwipo, Jeju Island, Korea. The new species has previously been regarded as the Northern Hemisphere population of the anti-equatorial species L. fasciatus, but molecular analyses of mitochondrial COI and 16S recovers deep genetic divergences of 9.4% and 15.0% between both the new species and topotypical specimens of L. fasciatus respectively. Limnichthys koreanus sp. nov. is distinguished from all other species of Limnichthys based on the following combination of colouration and morphological characteristics: vertebrae 38–40; 0–6 dorsal saddles joining mid-lateral stripe; small infraorbital sensory pores; a single median interorbital pore; and well developed vomerine teeth. Summary characters for comparative congeneric species are provided.

Sampling Methods
using scoop net
| Study Extent | Twelve specimens of the new species (35.8–45.3 mm TL, 33.4–40.0 mm SL) were collected from subtidal zones at depths between 1–5m in Seogwipo, Jeju Island, Korea between July 2022 and December 2023.Tissue samples were taken from the right side of the body, preserved in 99% ethanol, and deposited in the in the Marine Fish Resource Bank of Korea (MFRBK). We followed the immersion specimen production manual of the Marine Fish Resource Bank of Korea (MFRBK), under the National Institute of Marine Biological Resources (MABIK) of the Ministry of Oceans and Fisheries (MOF). |

Method step description:
- Methods for counting measuring follow Waite (1904), Nelson (1978), and Yoshino et al. (1999). Images of specimens were taken using a digital camera (D750; Nikon, Japan). Detailed morphological characteristics were examined with a stereomicroscope (SZX-16; Olympus, Tokyo, Japan). Osteological details were determined from X-ray images, cleared and stained specimens, and micro-CT data. Micro-CT scans were taken using Phoenix V-Tome-X C450 Volume Graphics® VGSTUDIO Max software and handled using Volume Graphics® myVGL viewer. Mitochondrial cytochrome c oxidase subunit I (COI) and 16S ribosomal RNA (16S) were amplified from extracted gDNA. Sequences were read by BigDye Terminator v3.1 cycle sequencing kits (Applied Biosystems, Foster City, CA, USA) with an ABI PRISM 3730XL analyzer (96 capillary type; Applied Biosystems).
