Comment

Redescribed as new by Ray, 1999, Mem. Zool. Surv. India, 18: 18. Chanda, 2002, Handb. Indian Amph.: 201, provided a brief account. Das and Dutta, 2007, Hamadryad, 31: 154–181, noted no larval descriptions in the literature. In the Amolops monticola group of Jiang, Ren, Lyu, Wang, Wang, Lv, Wu, and Li, 2021, Zool. Res., Kunming, 42: 574–591. Prasad, Gautam, Singh , Badola, Shrivastava, Dinesh, and Borzée, 2026, J. Threatened Taxa, 18: 29098–29105, found the species extirpated from the type locality (the only known locality) but presented a map of the potential range of the species.
