简单描述
型态特徵 | 形态测量图
脊椎骨: 38 - 44. The only member of the subfamily Anostominae with a single longitudinal stripe. It also lacks transverse bars across the dorsum. Resembles P. gracilis but is distinguished by the following characters: a dark horizontal stripe along the lower half of the lateral-line scale row and the upper half of the row adjoining; four branchiostegal rays; two pores on the sensory canal of the nasal bone between its anterior and posterior openings; four pores associated with the sensory canal of infraorbital one and arranged in an approximate square; nearly complete closure of the metapterygoid/quadrate fenestra; absence of a posterior process of the ectopterygoid running ventral to the palatine in lateral view; presence of a dorsal process of the mesopterygoid that wraps around the posterior of the palatine; and a palatine with a high arch and thick, blocklike morphology (Ref. 55429).
亚科 Anostominae 的唯一成员具有一个单一纵向的斑纹。 它也缺乏横过背面的横跨的横带。 与 P. gracilis 相似但是被借着下列的特征区别: 一条深色的水平斑纹沿着侧线鳞片列与列的上半部的下半部邻接的; 四个鳃条骨; 在它的前面与后面开口之间的鼻骨的知觉管上的二个孔; 四个孔伴随着眶下的知觉管而且排列成一个大约的正方形了; 几乎完成 metapterygoid/方骨窝窗的终止; 在侧面中缺乏外翼状流动的腹到颚骨的一个在后部突起; 有颚骨的后面的周围包装的中翼骨的一个背部突起; 而且一個顎骨具有一個高的弓與厚的, blocklike 形態學.(參考文獻 55429)
描述: 背鰭典型地有三條不分枝的鰭條與 10 分枝了而且片段了鰭條; 臀鰭典型地有三條不分枝的鰭條與八分枝了而且片段了鰭條; 胸鰭有 13-17個鰭條; 腹鰭典型地以9個鰭條，三件標本 8 鰭條.(參考文獻 55429)。
Adults are found in deep and clearwater pool (Ref. 55429). Stomach contents contain sand, woody debris and a fibrous plant material (Ref. 55429). Distinct pairs breed on densely grown weedy places (Ref. 205).
发现于深的而且水干净的水池了。 (参考文献 55429) 胃内含物包含沙子，植物残砾与一个纤维的植物。 (参考文献 55429)
