Comment
See accounts by Bourret, 1942, Batr. Indochine: 206-207; Inger, 1966, Fieldiana, Zool., 52: 24-28; Berry, 1975, Amph. Fauna Peninsular Malaysia: 32-33, and Inger, Stuebing, and Tan, 1995, Raffles Bull. Zool., 43: 121-122. Matsui, 1997, Copeia, 1997: 158–165, reported on advertisement call. 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. Das, Jankowski, Makmor, and Haas, 2007, Mitt. Hamburg. Zool. Mus. Inst., 104: 154, provided a brief description. See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 625. Das, 2007, Amph. Rept. Brunei: 36, provided a photograph and a brief account. Dehling, 2012, Zootaxa, 3328: 20-34, reviewed and rediagnosed the systematics of the species, and concluded that Leptolalax gracilis proper is restricted to Borneo and that Malay Peninsula populations represent two unnamed species (on now named Leptobrachella platycephala) conflated with Leptobrachella gracilis. Matsui, 2006, Zool. Sci., Tokyo, 23: 821-830, noted that the isolated record in western Thailand (Thong Pha Phum Forest, Kanchanaburi Province) by Chan-ard, 2003, Photograph. Guide Amph. Thailand: 78-79, is likely referable to Leptobrachella melanoleuca. The Gunung Benom population is now recognized as Leptobrachella platycephala. The Gunung Tahan population previously referred to this species remains unnamed.
