Dubois and Ohler, 1999, J. South Asian Nat. Hist., 4: 166, suggested that this taxon is a likely synonym of Bufo parietalis and they placed it in their Bufo scaber group. Chanda, 2002, Handb. Indian Amph.: 27, provided a brief account. Das and Dutta, 2007, Hamadryad, 31: 154–181, noted no larval descriptions in the literature (as Bufo silentvalleyensis). Subramanian, Dinesh, and Radhakrishnan, 2013, Atlas of Endemic Amph. W. Ghats: 35, provided a very brief characterization, photograph, and dot map.
