Das, 2007, Herpetol. Rev., 38: 291–292, noted several publications dealing with adult and larval morphology of this species long prior to its naming. Radhakrishnan, Gopi, and Palot, 2007, Curr. Sci., Bangalore, 92: 213–216, provided range extensions in Tamil Nadu and Kerala in the Western Ghats and discussed specific localities. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 467, who suggested that this name covers unnamed species. Das and Dutta, 2007, Hamadryad, 31: 154–181, noted several larval descriptions in the literature. Zachariah, Abraham, Das, Jayan, and Altig, 2012, Zootaxa, 3510: 53–64, reported on life history and larval development. Raj, Vasudevan, Deepak, Sharma, Singh, Aggarwal, and Dutta, 2012, Zootaxa, 3510: 65–76, reported on larval morphology and ontogeny. A very brief characterization, photograph, and dot map provided by Subramanian, Dinesh, and Radhakrishnan, 2013, Atlas of Endemic Amph. W. Ghats: 76. Sivaprasad, 2013, Common Amph. Kerala: 106–107, provided a brief account, photograph, and dot map for Kerala, India. Jobin, Deepak, and Nameer, 2012, Frog Leg, 18: 3–9, provided a range map and commented on larval morphology. Thomas, Suyesh, Biju, and Bee, 2014, PLoS One, 9 (2: e84809): 1–12, reported on vocal behavior. Senevirathne, Thomas, Kerney, Hanken, Biju, and Meegaskumbura, 2016, PLoS One, 11(3: e0151114): 1–23, described larval ontogeny. Janani, Vasudevan, Prendini, Dutta, and Aggarwal, 2017, Alytes, 34: 1–19, compared this species to Nasikabatrachus bhupathi in morphology, advertisement call, and molecular markers. Raj, Vasudevan, Aggarwal, Dutta, Sahoo, Mahapatra, Sharma, Janani, Kar, and Dubois, 2023, Alytes, 39–40: 69–71, reported on larval morphology.
