The dorsolateral and lateral surfaces of the body are dark brown with spots on the dorsolateral surface extending from the predorsal area to the base of the caudal fin. The adipose ridge is light brown. In "B. cessator" and "B. insignis", a small patch of light brown is occasionally present on the predorsal area. The belly, chest, and ventral surface of the head is cream or light brown, with a few scattered brown spots in "B. insignis". In "B. cessator", the dorsal and pectoral fins are cream with numerous brown spots scattered throughout and the pelvic and anal fins are cream with one or two dark-brown bands, one present occasionally at the base of the fins and another in the distal half of the fins; in "B. hypselurus" and "B. insignis", the dorsal, pectoral, pelvic, and anal fins are cream with a dark-brown band in the distal half of the fins. The caudal fin is cream with a dark brown band in the distal half and with a narrow midlateral prolongation. The barbels and pectoral spines are cream or light brown, with dark-brown spots, only present sometimes on the dorsal surfaces in "B. cessator" and "B. insignis".
