Issue
Differences with B. bynni occidentalis are: higher body, inferior lip reduced and without mental lobe and the number of scales. Compared to B. wurtzi the barbels are slightly longer, but many characteristics are similar.

背的軟條 (總數) : 13; 臀鰭軟條: 8. Diagnosis: last simple ray partly ossified at base (no strong spine) and distinctly longer than head; lower lip poorly developed, not forming a mental lobe, sometimes rubber-lipped; 10 dorsal fin branched rays; scale formula 4.5/24/3.5; 2 scales between lateral line and pelvic-fin base; 12 scales around caudal peduncle (Ref. 2940, 81282).
種已知只來自 23 公分 SL 的類型了。 BD/SL=40%. 用 B. wurtzi 的像那一樣的下巴葉的大寬的圓月. 最後的背部單一的鰭鰭條部分鈣化了但是不會形成棘。 它是清楚長度超過頭長,第一鰭條是第一初期的分枝鰭條。 清澈的從顏色。
