Description

Species of the genus Paraba have a slender body with nearly parallel margins while creeping. The largest specimens may reach about 8 cm in length. Both sides of the body are slightly convex. The pharynx is cylindrical and the prostatic vesicle is extrabulbar. The copulatory apparatus has a permanent, protrusible, conical penis occupying the entire male cavity, which is unfolded, and the female cavity is rounded and filled with a multilayered epithelium.

Paraba means multicolored in the Tupi language and alludes to the name of the type-species, Paraba multicolor.
