Leptobrachium sylheticum Al-Razi, Maria, and Poyarkov, 2021

Class: Amphibia > Order: Anura > Family: Megophryidae > Subfamily: Leptobrachiinae > Genus: Leptobrachium > Species: Leptobrachium sylheticum

Leptobrachium sylheticum Al-Razi, Maria, and Poyarkov, 2021, J. Nat. Hist., London, 55: 98. Holotype: JnUZool-A0120, by original designation. Type locality: "lowland mixed evergreen forest of Lawachara National Park, Moulvibazar District, Sylhet Division in the northeast of Bangladesh (24.325061° N, 91.786152° E; elevation 56 m a.s.l.)".

Common Names

Sylhet Litter Toad (Dinesh, Radhakrishnan, Deepak, and Kulkarni, 2023, Fauna India Checklist, vers. 5.0 : 5).

Sylhet Slender Armed Frog (Sarmah, Garg, Tajo, Upadhyaya K., Hanken, and Biju, 2026, PeerJ, 14(e20397): 42).

Distribution

Southern Khasi Hills region of Meghalaya, India, and nearby areas adjoining Bangladesh, as well as from the states of Manipur, Mizoram, and Tripura; likely in adjacent areas of southern Assam, including the Barak Valley and the Karbi Anglong Hills; also likely to occur in the Indian state of Nagaland.

Geographic Occurrence

Natural Resident: Bangladesh, India

Comment

External morphology, advertisement call, and molecular markers discussed in the original publication, where this species was placed in the Leptobrachium smithi complex along with Leptobrachium tenasserimense, Leptobrachium rakhinense, and Leptobrachium smithi, and also noted to have been confused in part with Leptobrachium hasseltii, Leptobrachium smithi, and Leptobrachium rakhinense in previous literature, which they detailed. Sarmah, Garg, Tajo, Upadhyaya K., Hanken, and Biju, 2026, PeerJ, 14(e20397): 1–62, reviewed the species, assigned it to their Leptobrachium smithi group, described cranial osteology as well as adult morphology, advertisement call, natural history, and provided a dot map of the distribution; they also noted that earlier records from southern Assam identified as Leptobrachium smithi are likely assignable to Leptobrachium sylheticum.
