Limnophys helonotus is a large member of the genus, the maximum SVL ranges from 60-70 mm. This species can be differentiated from its congeners based on the following combination of characters: the frontoparietals have low parasagittal cranial crests; prevomerine dentigerous processes are arch-like and extend laterally to outer edge of choanae; dorsal skin lacks osteoderms; dorsal skin is tuberculate and bears large flattened warts; the upper eyelid lacks elongate tubercles; and no tarsal fold. The head is as broad or broader than the body, head width 49.5-51% SVL. Snout is round when viewed dorsally and truncate when viewed laterally. Eye-nostril distance is 93.8-96.1% eye length. Supratympanic fold is present and indistinct while the tympanum is prominent, higher than wide, and separated from the eye by a distance 1.5-2 times width of tympanum. There is a pair of indistinct canthal folds present and no enlarged “horn-like” tubercles on eyelids. Fingers have weak lateral fingers; tips of fingers are rounded and lack pads. There are two metatarsal tubercles, the inner is weakly compressed and twice as long as wide. Coloration in preservative follows: brown above with a large amount of black or dark brown markings on the tubercles and folds. Broad brown labial bars divided by cream colored lines. Ventral coloration is cream with dark brown blotches. Groin is a dark brown and lacks a pattern.
Limnophys helonotus was originally described in Lynch (1975) as Amblyphrynus helonotus, Amblyphrynus later became synonymous with Eleutherodactylus, after which the genus name was changed to Limnophys.
