03C087C455105F64FF1DAB3FF78D558E.taxon	diagnosis	Diagnosis Rhinogobius sexistriatus can be well distinguished from all other congeners by the unique combination of the following features: (1) fins rays: second dorsal fin rays I / 8; anal fin rays I / 7; pectoral fin rays 17; (2) squamation: longitudinal scale series 26 – 28 (modally 27); perdorsal scales 4 – 5 (modally 5); (3) vertebral count 27; and (4) specific colouration: Cheek with six parallel black stripes on lower side in male. Branchiostegal membrane light blue and spotless in male. First dorsal fin bright orange on more than 1 / 2 dorsal region in male. Second dorsal fin brownish yellow with 3 longitudinal rows of brown spots and a distal yellow margin in male. Pectoral fin base greyish with a large, wide oblique black mark and an orange spot behind in male. Caudal fin greyish with 5 vertical rows of brown spots in male.	en	Chen, I-Shiung, Wang, Shen-Chih (2025): A new freshwater gobiid species of Rhinogobius Gill, 1859 (Teleostei: Gobiidae) from the hillstream of Julongjiang basin, Fujian Province, southeastern China.

03C087C455105F64FF1DAB3FF78D558E.taxon	description	Description Body proportions in Table 1. Body cylindrical anteriorly, compressed posteriorly. Head rather large, somewhat depressed in male. Eye large, dorsolateral. Snout pointed. Cheek fleshy in male. Lips thick. Mouth oblique, rear edge reaching to midline between anterior edge of orbit and anterior margin of pupil in male, but not reaching the vertical in female. Both jaws with 3 – 4 rows of conical teeth, outer jaws enlarged. Tongue margin rounded. Anterior nostril in short tube and posterior nostril round. Gill opening restricted, extending ventrally near but not reaching vertical midline of opercle. Vertebral count 11 + 16 = 27 (in all 3 specimens). Values in parenthese are the average. Fins. D 1 VI, D 2 I / 8; A I / 7; P 17; V I / 5 + I / 5 (distribution frequency in Table 2). D 1 rounded, 3 rd rays slightly longest, with rear tip while depressed extending just to D 2 origin in male, but not reaching the point in female. Origin of A inserted below second branched rays of D 2. The rear tips of D 2 and A rays when depressed fall well short of procurrent rays of C. P moderate large and oblong, its rear tip near reaching vertical line through anus. V rounded, spinous rays with somewhat pointed membrane lobe. C elliptical, rear edge rounded. Scales. Body with rather large ctenoid scales, anterior region of predorsal area naked; posterior dorsal area and belly cycloid. LR 26 – 28 (modally 27); TR 8; PreD 4 – 5 (modally 5); and SDP 6 – 7. Head and prepelvic region naked. Anterior edge of midpredorsal squamation near the midline of upper end of gellopening. ...... continued below TABLE 3.
