Distribution

Known from two disjunct populations; the eastern population is found from the Ri Bhoi district of Meghalaya state and the adjoining southern Kamrup district of Assam state (Garbhanga Reserve Forest and Mayeng Hill Reserve Forest ) between 90 and 145 m elevation; the western population is found from Tura municipality in the West Garo Hills district of Meghalaya state at 675 m and possibly as high as 875 m elevation, India.

Comment

Kharkongor, Saikia, and Deb, 2018, Rec. Zool. Surv. India, 118: 45, briefly summarized the range in India. See account by Mahony, Kamei, Teeling, and Biju, 2020, J. Nat. Hist., London, 54: 154–157, who corrected much of the literature and the range, noted that it was widely previously confused with Megophrys parva, and placed it in their Megophrys (Xenophrys) megacephala species group. In the Xenophrys megacephala group of Lyu, Zeng, Wang, Liu, Huang, Li, and Wang, 2021, Zootaxa, 4927: 9–40.
