पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 1; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 8. This species is distinguished by the following characters: with extremely narrow frontal bone, its width conspicuously smaller than half of its entire length; anterior portion of infraorbital 1 with strongly reduced laminar expansion, not reaching or at same level as posterior margin of nasal capsule; presence of dorsal-fin spinelet (Ref. 129024).
Body shape (shape guide): elongated; Cross section: oval.
Facultative air-breathing (Ref. 126274); Inhabits highly transparent brownish water (tea colored), up to one meter depth, with moderate current, and substrate composed of sand, gravel and larger rocks (typical at the rio Capivara, a tributary to the rio Paraguaçu basin). Found in syntopy with Characidium clistenesi, and both species were observed to forage next to each other, with no conspicuous interactions (Ref. 129024).
