Dzihunia pseudoamudarjensis, a new nemacheilid loach from the Syr Darya drainage (Teleostei: Nemacheilidae).

Dzihunia pseudoamudarjensis, new species, is described from the middle portion of the Great Fergana Canal in the Fergana Valley. The new species is distinguished from its congeners by having a complete lateral line with 84-86 pores, a slenderer caudal peduncle, a smaller dorsal and anal fin depth, and a wider interorbital distance. A key to Dzihunia species is provided.

, a new nemacheilid loach species (Teleostei, Nemacheilidae) from the Syr Darya River basin, Central Asia.

, new species, is described from the Sokh River, a former tributary of Syr Darya that today fails to reach the river, in the Sokh District, an exclave of Uzbekistan, surrounded by Kyrgyzstan. is distinguished from other species of in Central Asia by a truncate caudal fin with 13 or 14 branched rays, body without obvious mottling, dorsal-fin origin opposite to pelvic-fin insertion, and absence of the posterior chamber of the air bladder. Molecular data suggest that is closely related to from the Shakhimardan stream, a small tributary of Syr Darya in the Yordon village, another exclave of Uzbekistan in Kyrgyzstan.

Molecular diversity of Uzbekistan's fishes assessed with DNA barcoding.

Uzbekistan is one of two doubly landlocked countries in the world, where all rivers are endorheic basins. Although fish diversity is relatively poor in Uzbekistan, the fish fauna of the region has not yet been fully studied. The aim of this study was to establish a reliable barcoding reference database for fish in Uzbekistan.

Triplophysa ferganaensis, a new loach species from Fergana Valley in Central Asia (Teleostei: Nemacheilidae).

Triplophysa ferganaensis sp. nov. is described from the Shakhimardan stream, a small tributary of the Syr Darya, which does not reach the river in Fergana Valley.

, a new species of cave-dwelling loach (Teleostei, Nemacheilidae) from Chongqing, Southwest China.

We describe a new species of cave-dwelling loach, , based on specimens collected in a subterranean pool in a cave in Wulong County, Chongqing, Southwest China. The pool is connected to the Wujiang River drainage. differs from its congeners by the following combination of characters: eyes present, caudal fin with 18 branched rays; posterior chamber of the air bladder degenerate; stomach U-shaped; intestine without bends or loops immediately posterior to stomach; body smooth and scaleless, and lateral line complete.
