Pyxicephalus khasianus Anderson, 1871 and Rana laticeps Boulenger, 1882 (Dicroglossidae, Anura, Amphibia) are synonyms

The study of publications and of museum specimens allows unequivocal identification of the type specimens of Pyxicephalus khasianus Anderson, 1871. These specimens were collected by Thomas Jerdon at the same time as the type specimens of Rana laticeps Boulenger, 1882 and belong to the same biological species. We describe and figure the lectotypes of Pyxicephalus khasianus and of Rana laticeps and give measurements of the other specimens seen by the authors of the original descriptions of both taxa. Thus, both names having been regularly used in literature, the valid name of this species is Limnonectes khasianus (Anderson, 1871), and Rana laticeps Boulenger, 1882 is its junior subjective synonym.
