Espinas dorsales (total) : 17 - 19; Radios blandos dorsales (total) : 8 - 10; Espinas anales: 8 - 9; Radios blandos anales: 7 - 9. This species has spots on sides smaller than scales, aligned in about 15 regular series (vs. not clearly aligned); abdomen predominantly whitish or greyish in life (similar to R. gemmata, vs. reddish in R. ocotal; ventral angle of articular is acute (vs. right); the first neural spine oriented rostrad (vs. caudad); circumpeduncular scales as few as 17 (vs. always more than 19); distance from the caudal esophageal loop in gut to esophagus always greater than 24% gut length (vs. less than 16%) (Ref. 74403).
There are no unique autapomorphies. Body shape (shape guide): short and / or deep.
Adults occur in swampy areas with warm, murky water. They are found in weedy, mud-bottomed and sand-bottomed canals and drainage ditches (Ref. 5723).
