背棘 (總數): 0; 背的軟條 (總數): 10-12. Similar to females of P. latipinna but lacks rows of brown spots on side (may have row of dusky black spots).
類似 P. latipinna 的雌性但是在側邊上的缺乏列的褐色斑點.(可能有暗色黑色的斑點的列)
In backwaters and quiet pools of streams, sloughs, and ditches, usually over mud. This is an all-female species thought to have originated as a result of hybridization between P. latipinna and P. sphenops. Gynogenesis reproduction is triggered by copulation and stimulation by sperm from males of other species in the genus, either P. latipinna, P. mexicana, P. latipunctata, or rarely P. sphenops.
在溪流，泥坑與溝渠的滯水區與靜止的水潭中, 通常在泥上面。 這是被認為是在 P. latipinna 與 P. sphenops 之間的一個雜交的結果的一個全部雌性的種。 孤雌生殖繁殖被連結與刺激引起被來自任一親種的精液。

Reproduces gynogenetically (Refs. 8601, 8602, 8605, 5723, 125602), meaning once the sperm has penetrated the egg membrane, it takes no further part in the development of the embryo. Eggs develop following copulation and stimulation by sperm from males of other species in the genus, either P. latipinna, P. mexicana, P. latipunctata, or rarely P. sphenops. Viviparous (Ref. 8601), but there is no nutritional contribution by the mother during embryonic development to compensate for the depletion of stored reserves in the egg as embryos develop (Ref. 8606).北美洲: Nueces 河 (在哪裡可能地引入) 下游與 Rio Grande 下游，極端的德克薩斯南部, 對在墨西哥中的非拉克斯州。 在聖安東尼奧與桑河 Marcos ，德克薩斯的外來族群。
