[1][3] The generic name refers to streams, the breeding habitat of this frog (from Greek rheos meaning 'stream' combined with Hylas).

[6] This genus was erected in 2016 to accommodate former Ecnomiohyla miotympanum;[2] AmphibiaWeb still uses this earlier classification.

[2][6] The tympanum is distinct but dorsally obscured by the well-develop supratympanic fold.

Although the overall population is estimated to be stable, this species is facing some threats, most importantly habitat loss and degradation caused by small-scale agricultural development and logging.

Other potential threats are collecting for human consumption, pet trade, chytridiomycosis, and pesticides.
