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. 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 Leptolalax platycephalus) conflated with Leptolalax gracilis. Matsui, 2006, Zool. Sci., Tokyo, 22: 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 referrable to Leptolalax melanoleucus. The Gunung Benom population is now recognized as Leptolalax platycephalus. The Gunung Tahan population previously referred to this species remains unnamed.
