Type species: Abbottina psegma Jordan &amp; Fowler, 1903, by monotypy.</p><p>Pseudogobiops Berg, 1914: 499 (as a subgenus of Pseudogobio Bleeker, 1860). Type species: Gobio rivularis Basilewsky, 1855 (appearance of the type species is shown in Fig. 2).</p><p>Diagnosis.</p><p>The genus Abbottina can be distinguished from all other genera in the family Gobionidae by the combination of the following characteristic: mouth inferior; lips thick, relatively smooth, with small less-developed papillae or shallow grooves; lower lip with anterior fold, medial pad on lower lip forming two oval-shaped fleshy protuberances; jaws concealed beneath lips, without horny margin; barbel one pair (Fig. 3 A). The last unbranched dorsal-fin ray thin and soft; anal fin with five branched rays. Pharyngeal teeth in one row. Air-bladder moderately large, with two soft chambers (Fig. 4 A).</p><p>Description.</p><p>Body elongated, oblong, abdomen rounded; caudal peduncle short, compressed laterally. Lateral ethmoid broad, triangular in shape. Lachrymal and jugal superiorly contacted with lateral ethmoid, junction length on dorsal margin of jugal three-quarters in total length of dorsal margin, the third infraorbital narrow than the jugal (Fig. 5 A). Mouth inferior, lips thick, relatively smooth, with small less-developed papillae or shallow grooves; lower lip possessing one medial pad and two lateral lobes, the medial pad forming two oval-shaped fleshy protuberances, two lateral lobes connected with each other anterior from the medial lobe, forming the anterior fold. Jaws concealed beneath lips, without horny sheathed edge. Body covered with moderately small cycloid scales. Lateral line complete, almost straight. Breast scaleless, ventral region covered with scales. Anus slightly anteriorly positioned from the mid-point of pelvic-fin insertion and anal-fin base. Lateral-line scales 36–39; scales above lateral line 5.5–6.5; scales below lateral line 3–4.5; predorsal scales 11–14, small and irregularly arranged; circumpeduncular scales 12–16. Dorsal fin with seven branched rays, pectoral fin with 10–12 branched rays, pelvic fin with six or seven branched rays, anal fin with five branched rays. The last unbranched dorsal-fin ray thin and soft. Pharyngeal teeth “ 5–5, ” in one row. Air-bladder moderately large, total length slightly larger than half of thorax-anal distance, processing two chambers; anterior chamber rounded, encapsulated in thin soft membrane; posterior chamber larger than anterior chamber, oval-shaped (Table 1). Dorsal and caudal fins with several narrow dark stripe.</p><p>Distribution.</p><p>This genus is naturally distributed in East Asia, including Russia, Japan, Korea, and China (Fig. 6). The northernmost distribution is the Heilongjiang (Amur) River basin, and the southernmost distribution is the north tributaries of the Pearl River basin, including upstream of the Dongjiang, Beijiang, and Guijiang rivers (Lin 1981; Jin 1990). In the Yellow River basin, it is naturally distributed downstream of Hequ County of Shanxi Province (Li 1981). In the Yangtze River basin, it is naturally distributed to the east of Chengdu Plain, including Chengdu Plain (Zhang et al. 2019; Guo et al. 2021). In Japan, it is only naturally distributed in Honshu and Kyushu Islands (Jang-Liaw et al. 2019).</p></div>	https://treatment.plazi.org/id/DBC4CD0B396C5A55BF14BFADC0D72803	Public Domain	No known copyright restrictions apply.
