lived in the cave and a thick layer of bat dung was found on the ground. Groundwater extended into the cave, and the water rushed outside the cave in the case of heavy rain. So far, no other fish, shrimps, or aquatic animals were found in the cave. The subterranean river belonged to the Dagou river system, and was the main river of the Libo County, which runs through the whole county, enters Guangxi from the Laocun Xiang, and was the major tributary of the Duliu River system (Figure 2).

The species has a large head, and the width of the head is larger than its depth. The frontal torso is nearly cylindrical, the backend gradually compresses, and the head is slightly flattened. There is a short distance between the anterior and posterior nostrils, and the anterior nostril forms a short and tubular structure, which is truncated backward. The pectoral fin extends backward to or beyond the starting point of the pelvic fin. The body is naked. The eyes are completely degraded; and eye socket was filled in fat tissue and without any outside remnant indicating their presence. The superior and inferior caudal peduncles have well-developed soft finfolds. No carneous

flaps are present in the pelvic fin axilla. The air bladder is wrapped in a bony capsule, and the posterior chamber of the air bladder is developed into a membranous chamber, which is separated from the abdominal cavity and connected to the anterior chamber by a short duct. The whole body is white and transparent, when they are alive, they look a little red because the blood inside, and is unlikely to become black when it is fed in sunlight for a long term.

are shown in Table 2. The head is slightly flattened, lips are rounded, eyes vestigial. Anterior and posterior nostrils well separated. Anterior nostril forms short tubular and posterior nostrils elliptical. The fish has an inferior mouth, and the upper and lower lips are connected at the corner of the mouth. The upper jaw is curved and the lower jaw is spoon shaped. The mouth aperture is U-shaped, and its rear end reaches the bottom part of the posterior edge of the naris. It has three pairs of slim barbels, and one pair each of inner rostral barbels, outer rostral barbels, and mouth corner barbels. The inner rostral barbels are shorter, and the outer rostral barbels extend backward to exceed the rear edge of the posterior naris, while the maxillary barbels extend backward and their ends are appropriate at the center of the rear edge of the opercular bone. The superior and inferior sides of the caudal peduncle have well-developed ridge-like fatty soft fin folds; especially, the soft

folds between the superior caudal peduncle and the dorsal fin are more apparent than those in the inferior caudal peduncle, where its front end reaches the upper part of the anal fin. The superior soft fin folds originate from the rear edge of the dorsal fin base to one third of the front edge of the caudal fin base, where compressing the dorsal fin backward can reach the origin of the soft fin folds. The inferior soft fin folds originate from the rear edge of the anal fin base to one third of the front edge of the caudal fin base.

The rear end of the dorsal fin can be compressed to reach the soft fin fold origin. The fish has a long pectoral fin, which extends backward to or beyond the pelvic fin base. Also, the pectoral fin has a very special morphology, which does not have branched fin rays. The first and second fin rays are very long, forming a spoke-like shape. The ventral fin originates at a place opposite to the origin of the dorsal fin, and it extends backward to cover the anus and close to the origin of the anal fin. The distance from the anus to the anal fin origin is about 1 mm. The anal fin extends to its base to half of the caudal fin base. The posterior edge of the caudal fin is forked, and the upper lobe is slightly longer than the lower lobe.</paragraph>

The fish is naked, and the intact lateral line is superficially subcutaneously buried, which is flattened from the upper angle of the gill cover and extends backward to the center of the caudal fin base. Sensory tubes are present in the head connecting to the lateral

at the upper part of the posterior edge of the gill cover, and bifurcate into two lateral lines toward the head. These tubes travel from the supraorbital bone to the inner side of the anterior nostrils and from the infraorbital bone to the outer side of the nostrils, and connect to the two lateral lines via a transverse lateral line at the parietal bone. The whole body is colorless, and the living fish is translucent, where the internal organs are visible. The stomach is U-shaped, and the intestine is in its rear part, which is slightly curved and extends to the anus. The anterior bladder chamber is completely coated by the bony bladder sac, which has a bony posterior wall and no opening. However, the posterior bladder is a well-developed membranous chamber, which is separated from the abdominal cavity and connected to the anterior chamber by a short tube. An oval transparent area exists in the posterior branchial aperture, which is inset in both sides of the body.
