Könsmognad: Lm ?  range ? - ? cm
Max length : 12.5 cm SL hane/ej könsbestämd; (Ref. 2801)
Mjukstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i analfenan: 13 - 15. Diagnosis: body depth 3.8-4.8x and head length 3.5-4.0x SL; eye diameter 2.8-3.8x head length; scale formula 7.5/39-43/4.5; 7.5 scales between lateral line and dorsal fin origin; 39-43 scales in longitudinal series; 14 scales around caudal peduncle; 8 dorsal-fin branched rays; 10-12 anal-fin branched rays (Ref. 2940, 81282).
Body shape (shape guide): elongated; Cross section: compressed.
Affinities: meristic characters close to R. nigeriensis (with more number of branched rays; shorter head length and mouth). Maximum TL was recorded at 15.5 cm (Ref. 2801).
