简单描述

背棘 (总数) : 1; 背的软条 (总数) : 6 - 7; 臀棘: 1; 臀鳍软条: 4; 脊椎骨: 33 - 34. Distinguished from all other species of Crossoloricaria by having more teeth (4-8 premaxillary and 8-11 mandibular teeth); more coalescing plates (17-20); maxillary barbel longer (68-109 % HL), reaching middle or proximal third of pectoral fin; barbels of lower lip more developed (16-27% HL); interorbital width greater (16-21% HL); and first ray of dorsal, pectoral and pelvic fins produced beyond branched fin rays. Furthermore, it is distinguished from C. rhami by these osteological features: tip of first dorsal-fin pterygiophore passes between paired neural spines of 8th centrum and contacts posterior border of transverse process of 7th centrum; pectoral fin reaches anterior half of pelvic fin; pelvic skeleton with ischiac process of basipterygia elongated, longer than in C. rhami; and last pterygiophore of anal fin bears a bifid posterior process, ending at the middle of haemal spine of 18th centrum.
与所有的其他种的 Crossoloricaria 藉着具有更多的齿区分了;(4-8 上颌骨前的与 8-11个下颚齿) 多合并碟;(17-20) 上颌骨触须更长的 (68-109% HL), 达到中央或近端的胸鳍中的第三; 下唇更多发展的 (16-27% HL) 的触须; 眼间骨宽度比较大的 (16-21% HL); 而且第一个鳍条背部的, 胸鳍与腹鳍生产超过分枝的鳍条。 此外，它被这些骨学的特徵与 C. rhami 区分: 第一背鳍支鳍骨的顶端在第 8个椎体与第 7个椎体的横跨突起的接触在一起后缘的成对髓棘之间经过; 胸鳍达到前半部的腹鳍; 有着被延长的 basipterygia 的坐骨突起的腹鳍骨骼, 长度超过在 C. rhami 中; 而且臀鳍的最后支鳍骨有被终点在第 18个椎体的脉棘的中央的一个两裂的在后部的突起。
Occurs in the main river and major tributaries, always over sandy beaches. Stomach contents include larvae of aquatic insects, small seeds and debris. The holotype (male, 11.59 cm SL) carried 53 fertilized eggs (3.2-3.4 mm diameter) on its lips and another specimen was carrying 31 unfertilized eggs (3.1-3.4 mm diameter).
出现于主要的河与主要的支流, 总是在沙滩之上。 胃内含物包括水生昆虫幼生，小的种子与残砾。 holotype(雄鱼,11.59 公分 SL) 孕有 53 个受精卵 (3.2-3.4 mm 直径) 在它的唇，而且另一件标本正在携带 31个未受精的卵 (3.1-3.4 mm 直径) 。
