9A42C28026715596A5BB6E2E6434C524.taxon	diagnosis	Diagnosis. A new Cirrhimuraena species with the combination of following characteristics: pectoral fin very small, only 15.2 % of head length (HL) (in congeners> 21 % HL); HK 9.7 % of TL dorsal fin originates 1 ½ pectoral-fin length behind gill opening; tooth pattern unique, with only a single row of mandibular teeth; cirri on upper jaw 11; vertebrae 150, vertebral formula 13 - 53 - 150.	en	Lin, Yen-Ting, Lin, Yu-Hsiang, Han, Yu-San (2025): Cirrhimuraena taiwanensis sp. nov., a new species of cirri-bearing eel (Anguilliformes, Ophichthidae) from Yilan, northeastern Taiwan.

9A42C28026715596A5BB6E2E6434C524.taxon	description	Description. The morphometric and meristic measurements of the holotype are shown in Table 2. Body very elongate, cylindrical; body height is almost consistent from gill opening to anus, with depth at gill opening of 2.2 % of TL and depth at anus of 2.3 % of TL. Head moderate, with head length (HL) 9.7 % of TL. Tail longer than trunk, 63.6 % of TL. Anal fin low, situated right after anus, with pre-anal length 36.8 % of TL. Dorsal fin also low, originating far behind gill opening and pectoral fin; pre-dorsal length 13.2 % of TL. Pectoral fin very small, 15.2 % of HL, 1.5 % of TL; pectoral-fin base positioned at same vertical as gill opening; gill opening positioned on latero-ventral side, length 16.4 % of HL. Eye relatively large, positioned nearer to snout tip than rictus; eye diameter 8.9 % of HL; interorbital space slightly wider; interorbital length 6.1 % of HL. Anterior nostril tubular, positioned at snout tip, while posterior nostril lies slightly behind orbit. Snout long, pointed, 19.1 % of HL. Upper jaw longer than lower jaw, 35.7 % and 26.9 % of HL, respectively. Five small cirri on edge of upper jaw between anterior and posterior nostrils; 6 cirri behind posterior nostril. No cirri on lower jaw and tip of jaw in front of nostrils. Dentition pattern illustrated in Fig. 3. Teeth numerous, closely arranged in a band, and primarily small and pointed, with slightly larger teeth at ends. Vomerine teeth in 1 – 3 rows, extending to posterior of maxilla; 5 teeth form a small patch at prevomer. Maxillary teeth in 2 – 6 rows of small, conical teeth; mandibular teeth band in only a single row on both sides. Pre-dorsal vertebrae 13, pre-anal vertebrae 53, and total vertebral 150. Head pores tiny and indistinct, with supraorbital pores 1 + 3, infraorbital pores 3 + 2, preoperculomandibular pores 7 + 4, and supra-temporal pores 1 (Fig. 4). Lateral line pores before pectoral fin / gill opening 12, before dorsal-fin origin 16, and before anus 48. Dorsal surface of body grayish, with numerous tiny black spots; some melanophores concentrated at tip of snout. Ventral side whitish. Dorsal and anal fins translucent; pectoral fin whitish.	en	Lin, Yen-Ting, Lin, Yu-Hsiang, Han, Yu-San (2025): Cirrhimuraena taiwanensis sp. nov., a new species of cirri-bearing eel (Anguilliformes, Ophichthidae) from Yilan, northeastern Taiwan.
