Description

The snout-vent length of males is between 34.8 and 45.8 mm and that of females is between 38.2 and 49.8 mm. R. okaloossae is characterized by an unspotted dorsum, distinct dorsolateral folds that do not reach the groin, and reduced webbing of the feet, with at least three phalanges of the 4th toe being free of webbing and at least two phalanges of all other toes being free. In males, vocal sacs are internal.
R. okaloossae has an advertisement call made up of a series of 3-21 guttural "chucks" issued at approximately 5 notes per second, but slowing at the end of the call. Between calls, males periodically issue single softer notes, especially as a response to the presence of other males calling nearby.
