背棘 (总数) : 0; 背的软条 (总数) : 62 - 77; 臀鳍软条: 52 - 57. Diagnosis: long and narrow, "knife-shaped" frontal fontanel (Ref. 248, 81644), 2.5-3.0 times as long as wide (Ref. 81644). Tooth plates remarkably broad; median vomerine tooth plate length strikingly shorter than premaxillary length (Ref. 248). Vomerine tooth band very short, length 2.0-5.0% HL (mean 3.3), clearly shorter than premaxillary tooth band (Ref. 81644). Head rectangular in dorsal outline (Ref. 248), relatively large (HL 25.3-27.6% SL, mean 26.4) and wide (width 18.6-20.9% SL, mean 19.8)(Ref. 81644). Supraorbital and "dermosphenotic" never sutured; reduced suprabranchial organ (Ref. 248). Pectoral spine serrate only along anterior margin; flank neuromasts arranged in a regular pattern; postorbital bones not in contact; eyes laterally positioned, interorbital width 44.5-49.0% HL, mean 47.3; 14-16 rakers on 1st gill arch (Ref. 81644).
Coloration: preserved specimens dark reddish brown on back and flanks; ventrum and lower parts of paired fins pale (Ref. 81644).
特徵为它的刀状' 额骨囱门与用它的犁骨齿碟长度以平均长度显着短于上颌骨前的长度。 头部背面的矩形轮廓。 眶上的与皮蝶骨的' 从不缝合了。 齿板显着宽。 缩小的鳃前器官了。
Facultative air-breathing (Ref. 126274); Lacustrine species living in deeper as well as in shallow waters (Ref. 248, 78218). Larger specimens feed mainly on fish, especially Cichlidae; small specimens feed on insect larvae, Chironomids-Odonata (Ref. 248, 78218).
更深地被生活于的湖泊种以及在浅水区中。 较大的标本主要捕食鱼, 尤其慈鲷科鱼类; 小的标本吃昆虫幼生，宝刀鱼-蜻蛉.(参考文献 248)
