Climate: Subtropical

Description. D. iii, 8-9; A. iii, 5; P. xi-xiii, 13-15; V. vi-x, 15-17; l. lat. 50-53; predorsal scales 16-17. Vertebrae 32. Dorsal fin with 3 simple and 8-9 branched rays (mode 8). Anal fin with 2 simple and 5 branched rays. Pectoral fin with 10-13 simple (mode 11) and 13-15 branched rays (mode 14) (total 24-27; usually 25-26). Ventral fin with 6-10 simple (mode 7) and 15-17 branched rays (mode 16) (total 21-25, mode 23). Body and head very strongly dorso-ventrally compressed as anteriorly 2/3 region. Caudal very short, stout and compressed. Ventral profile completely flat. Head strongly dorso-ventrally compressed and rounded in dorsal view. Dorsal half of head densely covered with tiny sharp papillae. Upper lip with a single series of 14-17 small rounded papillae, with no distinct papillae on lower lip. Four rostral barbels and two barbels at both corners of mouth. Origin of dorsal fin slightly behind origin of pelvic fin. Pectoral fin very large, length longer than head length.  Ventral fin base close together and with complete connecting membrane as a suckig disc. Posterior margin of ventral fin extending beyond dorsal-fin origin and beyond anus and even beyond anal-fin origin in some adults. Caudal fin forked, lower lobe slightly longer than upper one. Dorsal part of body with small cycloid scales, ventral region between pectoral and pelvic fins naked. Body uniformly olive brown; predorsal region of dorsum uniform in adults, with irregularly rounded dark brown blotches in smaller sub-adults, dorsal side with irregularly rounded dark brown blotches. Pectoral fin brown without any dark marks. Caudal fin greyish black with two vertically light grey stripes.

Distribution: Asia: Kaoping and Tzengwen River basins (including Chiaryi, Tainan, Kaohsiung and Pingtung counties)  in southern Taiwan.

EcologySinogastromyzon nantaiensis occurs in very swift current of middle and lower reaches of river basins and can tolerate the slightly higher water temperature. Is always found in riffles at altitudes below 500 m. The body shape is well adapted to torrential flow in the riffles and runs among rocky substratum. It feeds mainly on tiny aquatic invertebrates, sedimentary detritus or fragile organic debris and prefers very clear water with low tolerance to the increased sediment load in waters.

Remarks. This endemic species, just described recently (Chen et al., 2002). In Taiwan, Sinogastromyzon nantaiensis is differentiated from the closely related S. puliensis by having fewer lateral-line scales (49-53, vs. 60-65), fewer predorsal scales (16-17, vs. 23-25), and pectoral fin base unmarked (vs. with many brown spots). This species generally distinguished from S. puliensis by their small adult size (mean 35.1-44.2 cm SL).

Material examined: Holotype. NMMBP 00465, 44.7 mm SL; Taiwan: Pingtung County: Liukuei, Darjin, Kaoping basin,  Laonon River; Aug. 1994, I-S. Chen et al.

Anal short, reaching (♀) or not reaching (♂) the rudimentary ray caudal. Caudal forked. Color in formalin: Upper body grayish black, lower pale, whole body with black round spots.

The present species is a carnivorous fish in Yamdrok Tso, it feeds on young fish and other aquatic animals. It spawns in the later half of May. Its digestive canal is 2.2 times as long as its body length. Air-bladder in 2 chambers, the posterior one twice the length of the anterior. This new fish closely resembles Gymnocypris maculatus Herz. (Herzenstein, 1888, p. 253—257, pl. XII, fig. 1, specimen No. 7333, collected from Chuanche ÜtfñJ), but differs from the latter in having: (1) 2nd dorsal ray slender and weak, not coarse and hard; (2) anterior end of mouth above the level of the lower edge of eye, not at the level of the lower edge of eye; (3) commencement of ventral opposed to 4 — 5th branched ray of dorsal, not opposed to 2nd dorsal branched ray.

Scales minute, distinct, more or less imbricate, presenmt on the whole body and cheeks and also covering the bases of the caudal rays.

Color of the type, in alcohol, pale brownish, dusky on side of body which is rendered by each of the scales endorned with a dark spot. Three broad transverse blackish bands on back before dorsal origin, with the interspaces 1/5 in its width, the first one invading the posterior portion of head and bordered in front and sides with pale edges. About 3 distinct, or rather indistinct, dark bands on back behind and 2 below dorsal fin. A vertical, indistinct, dark band at caudal base. Head invaded by anterior portion of the first band on the back, a transverse band between the posterior half of the orbit. Dorsal and upper half of side of snout, cheek and opercle also more or less dark. Dorsal fin with a basal blackish band, one narrow subterminal series of dots forming stripes and a broad one immediately below it. Ventral with about 2 stripes. Caudal with about 4 series of bands at its terminal 1/2 fin length, while these becoming indistinct and paler gradually foreward. Dorsal surfaces of pectoral and ventral rays dark, about forming two bands which are even visible from the from the ventrals view. from the ventrals view. Ventral side of head and body before ventrals pale. In the co-type (Tchang’s specimen) the coloration and markings is almost the same, but paler. The interorbital band extends foreward and not well differentiated from that anterior to it. The paired fins nearly uniform on the dorsal sides.

Distribution — Mountainous streams of Chekiang.

Remarks — The present species is named after Dr. T. L. Tchang, curator of Zoology at the Fan Memorial Institute of Biology and Lecturer in Zoology at the National University of Peking.
