Leptobrachium (Leptobrachium) abbotti — Dubois and Ohler, 1998, Dumerilia, 4: 22. Delorme, Dubois, Grosjean, and Ohler, 2006, Alytes, 24: 12.
Lowland Litter Frog (Das, Jankowski, Makmor, and Haas, 2007, Mitt. Hamburg. Zool. Mus. Inst., 104: 154; Das, 2007, Amph. Rept. Brunei: 33).

Removed from the synonymy of Leptobrachium hasseltii by Inger, Stuebing, and Tan, 1995, Raffles Bull. Zool., 43: 125, where it had been placed by Inger, 1966, Fieldiana, Zool., 52: 29. See identification table by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 68-69, to compare this species with other megophryids in the Sunda Shelf region. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 91-93, provided an account. Das, Jankowski, Makmor, and Haas, 2007, Mitt. Hamburg. Zool. Mus. Inst., 104: 154, provided a brief description. Das, 2007, Amph. Rept. Brunei: 33, provided a photograph and a brief account. Hamidy, Matsui, Shimada, Nishikawa, Yambun, Sudin, Kusrini, and Kurniati, 2011, Mol. Phylogenet. Evol., 61: 904-913, suggested that this name covers at least 4 lineages, phylogenetically interdigitated with other species; the one from eastern Kalimantan likely taking the existing name (this one forming the sister taxon of one of the lineages of Leptobrachium montanum), other lineages are: (2) one from Sarawak, (3) one from Kinabalu, Sarawak, and (4) another in Sarawak as well.
