Description[3]
R. rhodopus is a smallish tree frog with a pointed snout and body length of about 31–55 mm when adult, with females being larger than males. Its back is reddish-, pinkish-, or yellowich-brown without any green hues in living animals; in preserved specimens this becomes purplish brown. There are many darker spots all over the back, usually forming an X-shaped pattern behind the head and sometimes stripes across the lower back. Sometimes, there are a few large white spots on the back, also.[4] The hind legs and the upper sides of the arms are for the most part or entirely the color of the back; there are usually dark bands across the upperside of arms and hind legs. The sides, belly and toes are dark yellow, becoming dark pink in preserved specimens. Behind the arms, there is almost always a conspicuous large black spot on the flanks. The well-developed webbing of the toes is bright orange-red and not spotted. The eyes are light brown.
It can be distinguished from R. bipunctatus, with which it was long confused, by the smaller size (R. bipunctatus has a body length of about 37–60 mm) and spotted brown back without any green or olive (R. bipunctatus has a bright green to brownish green back without darker spotting). In individuals of similar size, R. bipunctatus has a much larger head.

Taxonomy[3]
R. rhodopus was described in 1960, based on specimens from
In 1999,
The mystery was unravelled when the type specimens of R. bipunctatus and R. namdaphaensis were finally examined and compared with other specimens from southeastern Asia in 2007. –, and R. namdaphaensis a junior synonym of R. rhodopus, a species that ranges widely from eastern India to the east and south and also occurs in lower-lying regions.
Thus, it seems that the 1999 study compared only specimens of R. rhodopus with other specimens of R. rhodopus, and therefore its conclusion that these constituted just one species was indeed correct. The mistake was rather the failure to compare even a single individual of the actual R. bipunctatus with the frogs from Thailand and Vietnam. Indeed, the authors of the 1999 study stated,
"[Liu and Hu] assumed that [R. bipunctatus] was green, possibly because Boulenger (1882) reported that it resembled R. reinwardtii.";[4]
but that it usually does have a green back was confirmed both by the description of R. htunwini and by examination of the
