7F2B87EA3358A645D8CAFC1050DA3E07.taxon	diagnosis	Diagnosis. Barbatula restricta is distinguished from all other species of Barbatula in Asia by its body depth continuously increasing between the nape and the dorsal-fin origin (vs. uniform in depth at least between the vertical through the mid-length of the adpressed pectoral fin and the dorsal-fin origin), and from all species except B. markakulensis by the tips of the paired fins being always formed by the 1 st and 2 nd branched rays (vs. 2 nd or 2 nd and 3 rd). Barbatula restricta is also distinguished from B. markakulensis by the absence of well-defined saddles on the back (vs. presence) and in somewhat higher vertebral count (42 – 45, usually 44 vs. 41 – 43, usually 42).	en	Prokofiev, Artem M.

7F2B87EA3358A645D8CAFC1050DA3E07.taxon	description	Description. For general appearance see Fig. 1; morphometric data are provided in Table 1. Body elongate, cylindrical in front of dorsal-fin origin and laterally compressed behind dorsal-fin base; dorsal contour straight, increasing continuously in depth between nape and dorsal-fin origin. Caudal peduncle compressed, shorter than head, 2.0 – 2.3 times longer than deep. Head depressed; snout obtuse, not compressed laterally, equal to or greater than postorbital head length; eyes situated dorsolaterally; space between anterior and posterior nostril 1.0 – 1.5 times in length of posterior nostril. Mouth (Fig. 2) inferior, strongly arched; processus dentiformis small, notch on lower jaw absent; lips moderately furrowed; upper lip with a short median incision; lower lip with small, oval, posteriorly pointing mental lobes, without lateral expansions. Inner and outer rostral barbels reaching a level of anterior and posterior nostrils, respectively; maxillary barbel reaching to vertical through posterior eye margin. Lateral line complete, with 70 – 80 pores, reaching to caudal-fin base. Supraorbital canal complete, not confluent with infraorbital canal; supratemporal commissure confluent with infraorbital canal. Pores in cephalic sensory canal system: 7 – 8 in supraorbital canal, 10 – 12 in infraorbital canal, 7 – 9 in preoperculomandibular canal, 3 in supratemporal commissure. Dorsal fin with 3 – 4 (usually 3) unbranched and 7 branched rays, with a straight distal margin, its origin closer to caudal-fin base than to tip of snout. Anal fin with 2 – 3 (usually 2) unbranched and 5 branched rays, with a straight to slightly convex distal margin. Pectoral fin with 1 unbranched and 10 – 12 (usually 12) branched rays; pelvic fin with 1 unbranched and 6 – 8 (usually 7) branched rays. Tips of paired fins formed by 1 st and 2 nd branched rays. Pectoral fin 1.2 times longer than pelvic fin, pectoral fin not reaching halfway to pelvic-fin origin when pressed to flank. Pelvic-fin origin below dorsal-fin origin or slightly behind it, not reaching to anus. Caudal fin emarginate, upper lobe as long as lower one. Branched caudal-fin rays 8 + 8. Flank and back behind dorsal-fin origin covered by scales. Scales with a small eccentric to moderately large subcentral focal zone (Fig. 3). Flank and back in front of dorsal-fin base without scales or with few isolated scales between the pectoral-fin tip and dorsal-fin origin. Intestine forming a small coil, not touching ventral margin of stomach (Fig. 4). Anus situated about one eye diameter in front of anal-fin origin. Free portion of gas bladder absent. Osteology. Sphenotic contacting epiotic, lateral fontanelle absent. Supraethmoid-ethmoid fused with prevomer. Urohyal elongate (length: height ratio 2.3 – 2.6), with deeply indented posterior margin. Basibranchial – 4 absent; two pharyngobranchials. Distal margin of neural complex flat, slightly concave in posterior third. Posterior processes of gas-bladder capsule very weak. Vertebrae 42 – 45 (mean 44, n = 14). Five hypurals. See details in Prokofiev (2007: Fig. 14). Coloration in preservative. Background colour pale-yellowish to whitish with brownish-gray to dark-brown pattern. Dorsal and lateral parts of head and body mottled with small irregular dark-brown blotches sometimes extending onto belly, sometimes larger and more pronounced on back; no dorsal saddles; ventral surface of head and body pale-yellowish or whitish without colour pattern, a mottled belly in some individuals. All fin rays marked with pronounced brownish-gray blotches forming irregular transverse streaks. Peritoneum pale-whitish, with scattered black melanophores more densely set along vertebral column.	en	Prokofiev, Artem M.

7F2B87EA3358A645D8CAFC1050DA3E07.taxon	etymology	Etymology. The specific epithet is made from the Latin word “ restrictus ” (restricted) referring to a narrow distribution of this species. An adjective.	en	Prokofiev, Artem M. (2015): A new species of Barbatula from the Russian Altai (Teleostei: Nemacheilidae). Zootaxa 4052 (4): 457-464, DOI: 10.11646/zootaxa.4052.4.3
7F2B87EA3358A645D8CAFC1050DA3E07.taxon	distribution	Distribution and conservation. Barbatula restricta is only known from the Lake Saldan-Kol (= Dlinnoye) basin, which drains to the Builyukem River. The Builyukem River flows to the upper Chuya, a headwater river of the Ob in south-western Siberia (Fig. 5). It was found to be quite abundant in the lake and its tributaries, mostly in the lowermost part of small creeks flowing into lake (A. S. Golubtsov, personal communication, 2001). The Builyukem River basin has not been searched for this species. It was not found in the main channel of the Chuya River. This is a species with a very small known range (about 30 km 2) and it might be sensitive to pollution and the destruction of habitats. Currently, the species seems not to be threatened.	en	Prokofiev, Artem M. (2015): A new species of Barbatula from the Russian Altai (Teleostei: Nemacheilidae).

7F2B87EA3358A645D8CAFC1050DA3E07.taxon	discussion	Remarks. Twelve species of Barbatula are currently recognized as valid in Asia. Three additional nominal species (B. cobdonensis, B. compressirostris and B. shansi) are very poorly studied though they might represent valid species (Table 2).	en	Prokofiev, Artem M.
