Bengal, 1870: 67; syntypes are ZSIC 2776-78 according to Chanda, Das, and Dubois, 2001 "2000", Hamadryad, 25: 109, although Sclater, 1892, List Batr.

Comment

The name Rana flavescens Jerdon, 1853, was considered a junior synonym of Rana kuhlii by Theobald, 1868, J. Asiat. Soc. Bengal, 37: 80, subsequently considered a possible synonym of Rana temporalis by Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 63. This tentative synonymy was continued by Boulenger, 1890, Fauna Brit. India, Rept. Batr.: 459; Boulenger, 1920, Rec. Indian Mus., 20: 159; and Chanda, Das, and Dubois, 2001 "2000", Hamadryad, 25: 109, although no author ever used this name as a senior synonym of Hylorana temporalis.  Biju, Garg, Mahony, Wijayathilaka, Senevirathne, and Meegaskumbura, 2014, Contr. Zool., Amsterdam, 83: 303, recognized the species as distinct, placed it in their Hylarana flavescens group, and revised the species and its relatives.
