簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 12 - 15; 背的軟條 (總數) : 9 - 11; 臀棘: 3; 臀鰭軟條: 7 - 9. This species is distinguished from its congeners, except G. labiatus, by having a thick, extremely well developed lips, with the lower lip deeply notched medially; differs from labiatus by the presence of a dark band extending posteroventrally from the dorsal-fin origin (vs. absent), and by the dorsal, anal and caudal-fin color patterns, where fins are partially or completely covered with well-defined circular dots (vs. small longitudinal stripes) (Ref. 118066).
Cross section: compressed.
This species is found exclusively in stone bottom habitats, covered with all sizes of stones and rocks along the rio Quaraí and its tributaries (Ref. 118066).
