简单描述
型态特徵 | 形态测量图
背的软条 (总数): 11-12; 臀鳍软条: 9; 脊椎骨: 36. Is uniquely diagnosed by the presence of 10 to 14 oblique bars on the sides of the body, extending posteroventrally from the lateral line and independent of the 8 or 9 dorsal transverse bars which are usually present in species of Characidium. Is also distinguished from other species of Characidium from southern Brazil, except C. pterostictum, by the spotted caudal fin. From C. pterostictum, it is easily distinguished by the number (12) of series scales around the caudal peduncle (14 in C. pterostictum). Fourth ray of pectoral fin ray longest, not reaching or just reaching to pelvic fin origin. Third or fourth ray of pelvic fin longest, reaching area between anal opening and anal fin origin (Ref. 27672).
独特地被鉴定藉由有 10 到 14个斜纹在身体侧边上, 腹面后方地延伸从侧线与 8 或者 9 的中立派背部的横跨横带通常那是出现在 Characidium 的种. 除了 C. pterostictum 以外，也被与来自巴西南部的其他种的 Characidium 区分, 藉由有斑点的尾鳍。 从 C. pterostictum ，它尾梗的周围是藉着容易地区别的系列鳞片的数字 (12) 。 (14 在 C. pterostictum 中) 胸鳍鳍条的第四鳍条长的, 不达到或正好延伸到腹鳍起点。 腹鳍的第三或第四鳍条长的, 达到在肛门开口与臀鳍起源之间的区域.(参考文献 27672)
All specimens collected were from middle courses of medium-sized rivers with rocky and muddy bottoms and moderate to strong water current (Ref. 27672).
收集的所有的标本来自中等大小河的中央路线有岩石的与泥底部与平稳或强烈的水流.(参考文献 27672)
