脊椎骨: 31. Distinguished from congeners by the following combination of characters: body very slender, depth 18.4-23.4% SL: head length 20.6-26.6% SL; snout length 8.1-10.8% SL; upper jaw length 4.3-7.2% SL; mouth subterminal; all fins and lower portion of the head cherry red in adults; caudal fin with broadly blackened distal margin; upper jaw darkly pigmented, appearing as a mustache; lateral stripe, when present, from opercle margin to tip of middle caudal rays; anal fin rays 11(one specimen with 10); lateral line scales 36-41; scales above lateral line 4-5; scales below lateral line 4 (one specimen with 5); premaxillary teeth 4 (one specimen with 3); and dentary teeth 3-4 (Ref. 30270).
与同类区分了藉由跟随组合特征: 身体非常细长的, 深度 18.4-23.4% SL: 头长 20.6-26.6% SL; 吻的长度 8.1-10.8% SL; 上颌长度 4.3-7.2% SL; 嘴接近端位的; 当成鱼时的所有鳍与头部樱桃红色的低部分; 宽广地尾鳍有变黑的末梢部的边缘; 上颌暗有颜色,呈现髭; 侧面的斑纹，当存在时, 从鳃盖边缘到中央尾部的鳍条的顶端; 臀鳍棘条 11;(一件标本具有 10) 侧线鳞片 36-41; 鳞片在侧线上面 4-5; 鳞片在侧线下 4;(一件标本 5) 上颌骨前的齒 4;(一件標本有三個) 而且齒骨齒 3-4.(參考文獻 30270)
