29DCCB12F4F85E91AFC577CE36A02436.taxon	diagnosis	Diagnosis. Lefua nishimurai sp. nov. can distinguished from all other species of Lefua by combing following features: absence of rhomboid or triangular dark blotches on middle of caudal fin base; absence of black longitudinal stripe on both body sides in mature males; absence of dusky cross bars on dorsal area of body; absence of dusky bar beside dorsal fin base; eyes located dorsally on head; narrow conspicuous longitudinal mark between base of outer rostral barbel and eye; small dorsal fin; small orbit diameter (6.3 – 11.2 % of head length); small value of interorbital width relative to body width (28.1 – 39.4 %); dark spots dorsally and ventrally on caudal fin base; small dark brown spots from snout to caudal peduncle; small dark spots on dorsal and caudal fins (approximately same size as eyes).	en	Katayama, Yuta, Sawada, Naoto (2024): Integrative taxonomy revealed a new species of Lefua (Teleostei, Nemacheilidae) from Fukui Prefecture, Japan.

29DCCB12F4F85E91AFC577CE36A02436.taxon	description	Description. Measurements and counts listed in Table 4. Body elongated and cylindrical, slightly longitudinally flattened, and caudal peduncle laterally flattened. Dorsal and ventral sides of caudal peduncle keeled, and depth of caudal peduncle, including keel, about same as body depth. Head small (less than one-fourth of SL), slightly dorsoventrally compressed. Snout relatively long, comprising 38.7 % in holotype (32.3 – 46.4 % in paratypes and additional specimens) of head length, with tip rounded in dorsal view. Eyes positioned on dorsolateral surface of head (Figs 6 – 8), very small. Interorbital width comprises 51.5 % (42.9 – 59.0 %) of body width, and orbit diameter comprises 6.6 % (6.3 – 11.2 %) of head length (Figs 6 – 8). Mouth subterminal; small and inferior, slightly arched. Upper and lower lips fleshly and smooth (Figs 7, 8). No median incision in upper lip. One median notch in lower lip. Three pairs of barbels, two pairs of rostral barbels, and one pair of maxillary barbels. Inner rostral barbel relatively short, reaching to or slightly past vertical through anterior margin of eye when extended horizontally, outer rostral barbel longest, slightly past vertical through posterior margin of eye when extended horizontally, maxillary barbel past vertical through posterior margin of eye when extended horizontally. Nostrils separated from each other, anterior nostril formed as 1 long nasal barbel, posterior nostril larger than anterior nostril, anterior nostril at anterior side of 1 nasal barbel, close to base. Nasal barbel extended horizontally past posterior border of eye. Dorsal and ventral keels on caudal peduncle; dorsal keel starting slightly posterior to extremity of dorsal fin base, ventral keel starting posterior to extremity of anal fin base. Length of caudal peduncle 1.0 (1.0 – 1.3) times depth of caudal peduncle (depth including keel). Scales embedded on body. Lateral line absent. Dorsal fin rounded. Origins of dorsal fin nearer to caudal fin base than to tip of snout. Pectoral fin horizontal. Pelvic fin anterior to dorsal fin. Anal fin rounded. Anus positioned slightly anterior to anal fin. Caudal fin rounded. Dorsal fin with 4 (3 – 4) simple and 5 (5 – 6) branched rays. Second branched ray longest. Anal fin with 4 (3 – 4) simple and 5 (5 – 6) branched rays. Pectoral fin with 1 simple and 11 (10 – 11) branched rays. Second branched ray longest. Pelvic fin with 1 simple and 5 branched rays. No pelvic axillary lobe. Caudal fin with 2 (1 – 2) simple, 6 (5 – 7) branched, 7 (6 – 7) branched and 1 (1 – 2) simple principal rays. Total vertebrae 41 (39 – 43); abdominal vertebrae 23 (21 – 23), caudal vertebrae 18 (16 – 21).	en	Katayama, Yuta, Sawada, Naoto (2024): Integrative taxonomy revealed a new species of Lefua (Teleostei, Nemacheilidae) from Fukui Prefecture, Japan.
