类似 P. latipinna 的雌性但是在侧边上的缺乏列的褐色斑点.(可能有暗色黑色的斑点的列)
Adults are found 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，泥坑与沟渠的滞水区与静止的水潭中, 通常在泥上面。 这是被认为是在 P. latipinna 与 P. sphenops 之间的一个杂交的结果的一个全部雌性的种。 孤雌生殖繁殖被连结与刺激引起被来自任一亲种的精液。

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。
