背鰭 (合計) : 15 - 25; 臀鰭: 19 - 24; 脊つい: 29 - 30. Distinguished from all members of Hypsolebias flavicaudatus complex by having a series of light golden to light blue short lines between the sub-distal portion of the dorsal-fin rays in males (vs. never a similar color pattern). The following combination of characters can be useful to diagnose from other members of the complex: 4-6 dorsal fin filaments, tips in much surpassing posterior margin of caudal fin; a triangular bluish white spot on the anterior portion of the dorsal-fin base in males; largest spot on the centre of the flank in females about equal to eye in size; pre-pelvic length 44.3-47.7% SL in males and 49.5-54.9% SL in females; anal-fin base in males 36.9-41.4% SL; head length in males 29.2-31.4% SL; body depth in males 37.9-40.4% SL; caudal peduncle depth in males 13.6-15.4% SL (Ref. 89836).
Occurs in seasonal swamps (Ref. 89836).
