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). They prefer coastal plains and slow moving waters of the lower river valleys (Ref. 7335). Food consists of worms, crustaceans, insects and fish (Ref. 7020).
