Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 1012. Similar to females of P. latipinna but lacks rows of brown spots on side (may have row of dusky black spots).

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. Parthenogenesis reproduction is triggered by copulation and stimulation by sperm from either parental species.
