Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical
South America: Madeira River drainage of the Amazon basin. Mostly found in the upper reaches in Guaporé and Mamoré rivers.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 15.9 cm SL male/unsexed; (Ref. 79512)
Dorsal spines (total): 1; Dorsal soft rays (total): 5; Anal soft rays: 10; Vertebrae: 38 - 39. Diagnosed from all congeners by having the following characters: a short cranial fontanel, with the opening restricted to the frontals; a genital papilla with thick flap of skin around the deferent duct in males; and a notched anal fin in adult males. Differs further from other species of the genus by having nasal bone partially sutured to lateral margin of mesethmoid; 7-8 branched rays on anal fin; 10-11 ribs; and 38-39 post-Weberian vertebrae. Other distinguishing characters include: third nuchal plate well projected laterally with curved tip; and caudal-fin lobes of mature females similar in length, but mature males with slightly elongated upper lobe (Ref. 79512).
Body shape (shape guide): elongated.
Reaches sexual maturity above 8.0 cm SL (Ref. 79512).
