Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 11; गुदा कांटा: 4 - 5; ऐनल सौफट रेज़: 41 - 43; जानवरों की रीड़ का जोड़: 37 - 40. This species is distinguished from R. molossus by having fewer branched anal-fin rays (41-43, versus 43-47). It differs from R. itupiranga by having more anal-fin rays (41-43, versus 38-41), fewer scale rows between lateral line and anal-fin origin (15-16, versus 18-19) and fewer scale rows around caudal peduncle(27-28, versus 30-31).
