Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 6. Differs from all other species of the genus Rhinodoras by the following combination of characters: pale, largely absence of dark pigmentation on ventral surfaces; anterior midlateral plates shallow to moderately deep, depth of fifth plate 16.6-26.2% of corresponding body depth; dorsal and ventral wings of anterior plates about equal in depth; midlateral plates anterior to vertical through pelvic-fin origin usually five; tympanal portion of lateral-line canal weakly ossified with two or three emergent plates, posterior-most largest with low medial ridge or procumbent thorn; postcleithral process moderately long and narrow, depth 23.9-34.5% of length; adipose eyelid moderate to large, horizontal diameter 10.9-14.6% of HL; pectoral fin rays usually eight; one-part gas bladder with terminal diverticula small and fused (Ref. 75166).
Body shape (shape guide): elongated.
