توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل) : 10; شعاع نرم باله مخرجي: 9; مهره ها: 28 - 29. Rasboroides pallidus differs from R. vaterifloris and R. nigromarginatus by having dorsal-fin origin 3 (vs. 1) scale-widths behind pelvic-fin origin and body depth of 34.3-37.5 % SL in males, 33.0-36.7 in females (vs. 31.1-32.8 in males and 31.0-31.7 in females of R. vaterifloris, and 28.2-33.0 in males and 26.9-29.1 in females of R. nigromarginatus). It can be differentiated from male R. rohani by having a smaller size of up to 24.6 mm SL (vs. up to 35.5 mm SL), having 1/2 6 1/2 or 1/2 7 1/2 (vs. 1/2 8 1/2) scales in transverse line on body, 20-24 (vs. 25-28) scales in lateral series on body, and 2 (vs. 1) lateral processes to the kinethmoid. Female R. pallidus differs from female R. rohani by possessing a greater eye diameter (39-40 % HL, vs. 29-34) and a greater interorbital width (33-36 % HL, vs. 25- 28) (Ref. 94541).
Found in shallow, slow-flowing, densely shaded lowland rain-forested streams with a sandy-silt
substrate (Ref. 94541).
