背的软条 (总数) : 15 - 23; 臀鳍软条: 17 - 25; 脊椎骨: 28 - 29. Diagnosis: Austrolebias bagual differs from all other species of Austrolebias by the unique colour pattern on the body and dorsal fin in males; usually consists of an overall light brown to dark brown coloration with 3-6 dark grey, narrow vertical bars, bars becoming gradually shorter and fainter towards caudal peduncle (vs. never similar colour patterns); dorsal fin light bluish-green, with 5-7 black vertical bars extending from the base to the medial portion of the fin (vs. absence of a such pattern in the remaining Austrolebias; females lack the pair of black spots arranged vertically in close proximity on the posterior portion of the caudal peduncle, sometimes coalescing to form an 8-shaped blotch, typical of most of the A. adloffi species group (except A. arachan and A. viarius) (Ref. 118216).
Body shape (shape guide): elongated; Cross section: compressed.
