Related to Limnonectes kuhlii according to the original publication. Matsui, Panha, Khonsue, and Kuraishi, 2010, Zootaxa, 2615: 1-22, suggested that the population from Loei, Thailand, is likely a distinct species. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 68–69, provided a photograph and brief account for eastern Thailand, and (p.136), detailed the range in Thailand. Niyomwan, Srisom, and Pawangkhanant, 2019, Field Guide Amph. Thailand: 274–275, provided a brief account (photographs, habitat, and range) for Thailand (in Thai).
