Etymology: Rhinogobius:Greek, rhinos = nose + Latin, gobius = gudgeon (Ref. 45335); sudoccidentalis:Name from Latin words 'sud' meaning 'south' and 'occidentalis' for 'western', for this species was discovered in Chongqing and Guizhou Province in the southwestern region of China.

خارهاي باله پشتي (کل) : 7 - 8; شعاع نرم باله پشتي (کل) : 8 - 9; خارهاي باله مخرجي: 1; شعاع نرم باله مخرجي: 6 - 7; مهره ها: 29. This species can be distinguished from its congeners by the following characters: D1 VI-VII, D2 I,8-9; longitudinal scale series usually 22-24 (most commonly 23), while the transverse scale series typically comprises 7-8 scales (most commonly 8); predorsal scale series absent; total vertebrae 12 + 17 = 29; a black line stripe beneath the eye that extends to the mandible (Ref. 132591). Cross section: oval.
Occurs mainly in areas characterized by large cobblestone substrates and slow-flowing water at depths ranging from approximately 30-50 cm. This species utilizes the cobblestone bottom as an egg deposition site, with eggs characterized as large (size 1.6-2.1 mm). During periods of high water levels in the creek, individuals aggregate near the shore to seek refuge from the rapids (Ref. 132591).
