Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 14; Anal spines: 0; Anal soft rays: 9; Vertebrae: 28 - 29. Distal part of gonopodium blade ray 3 bluntly pointed; three quarters of the caudal fin with fine red stripes; claw of tip of gonopodium ray 5 greatly enlarged; height/length ratios of tip of blade 5.6-6.3; dark pigmentation of the midlateral band continuous with the dark dorsal pigmentation of the sword in male. Caudal fin in males ray 5-8 forming a long sword; pelvic fin in females reaching to anal-fin base, in males to middle of gonopodium, second ray extremely prolonged and split, middle region thickened (Ref. 42936).
Collected in an area where the water is gray and substratum consists predominantly of large black boulders, gravel and mud; aquatic vegetation mainly with reeds and Vallisneria (Ref. 42936).
