Dentary pores 1-2; infraorbital pores 3-4; lachrymal pores 2; extrascapular pore 1. Caudal fin base with a prominent dark spot at the center, surrounded by a light ring. Differs from B. pyema in having a deeper body, depth 32.5-39.4% (versus 26.3-32.7); fewer lateral line scales, 25-26 (versus 27-28); fewer vertebrae, 26-29 (versus 28-29); and color pattern. Males are overall dark with a brown spot on each scale on sides. No dark blotch on cleithrum, opercular margin, nor on dorsolateral side of caudal peduncle (Ref. 46238). |
