簡短描述
型態特徵 | 形態測量圖
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).
亞科 Anostominae 的唯一成員具有一個單一縱向的斑紋。 它也缺乏橫過背面的橫跨的橫帶。 與 P. gracilis 相似但是被藉著下列的特徵區別: 一條深色的水平斑紋沿著側線鱗片列與列的上半部的下半部鄰接的; 四個鰓條骨; 在它的前面與後面開口之間的鼻骨的知覺管上的二個孔; 四個孔伴隨著眶下的知覺管而且排列成一個大約的正方形了; 幾乎完成 metapterygoid/方骨窩窗的終止; 在側面中缺乏外翼狀流動的腹到顎骨的一個在後部突起; 有顎骨的後面的周圍包裝的中翼骨的一個背部突起; 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個分枝與分段的鰭條; 臀鰭典型地有三條不分枝的鰭條與八個分枝與分段的鰭條; 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).
發現於深的而且水乾淨的水池了。 (參考文獻 55429) 胃內含物包含沙子，植物殘礫與一個纖維的植物。 (參考文獻 55429)
