简单描述 型态特徵 | 形态测量图

背的软条 (总数): 12; 臀鳍软条: 8. Is uniquely diagnosed by the W-shaped lateral marks on the body, which are formed by a concentration of melanophores in three scales of the lateral and two adjacent scales of the series situated immediately below. Is also distinguished from other species of Characidium from southern Brazil in having 12 series of scales around the caudal peduncle (14 in C. pterostictum), complete lateral line (incomplete in C. rachovii), 37-38 lateral scales (36 or fewer in C. orientale and C. occidentale); and lack of oblique bars below lateral line (10-14 such bars present in C. serrano).
独特地在身体上被鉴定藉由 W 形的侧面标志, 那是在侧部与被位于的系列的二个毗连鳞片的三个鳞片中由黑色素细胞的集中形成吗紧邻。下方 也被与来自巴西南部的其他种的 Characidium 区分尾梗 (14 在 C. pterostictum 中) 的周围有 12个成列的鳞片, 侧线完整 (不完全的在 C. rachovii 中),37-38个侧面的鳞片;(36 或比较少的在 中 C. orientaleC. occidentale) 而且缺乏斜纹在侧线下.(10-14条如此的横带出现在 C. serrano)

生物学特性     字汇 (例如 epibenthic)

Occurs in diverse habitats including large sandy beaches of wide, open lagoon systems to smaller muddy or rocky streams with slow current or even swampy environments (Ref. 27672).

出现于包括对比较小的泥泞或岩石的溪流且水流和缓的地方或甚至沼泽的环境宽又开放泻湖系统的大沙滩的不同的栖息地。 (参考文献 27672)
