The white-lipped horned toad, Megophrys major, is a common and widely spread species found from Northeastern India, Myanmar and southern China south through northwestern Thailand, northeastern Cambodia, and the Laos and Viet Nam highlands. It is found between 250-2500 m asl (van Dijk et al. 2004; Tran et al. 2008).
Megophrys major is a brown, smooth-skinned frog with dark coloration on its breast and upper belly, and a snout-vent length of about 7-8 cm. It has a dark triangle on the top of its head, between its eyes and barred legs.Its mottled brown dorsal pattern lends it excellent camouflage on the forest floor.Characteristic of the species is the thin white line on its upper lip (Humtsoe et al., 2008) to its armpit.Also called Anderson’s eyebrow frog, its names refer to the small fleshy projection above its eyes (Halliday 2016; Tran et al. 2010).
It exclusively inhabits the floors of evergreen forest areas, in monsoon and perennial rain climates, breeding in clear, swift-flowing streams (van Dijk et al. 2004).Eggs are reported in ovary at 2mm in diameter (Daniel 1962).Its tadpoles feed from the surface of the water, using funnel-like oral discs which points up, typical of the genus (Halliday 2016, Lathrop 1997).
While abundant through its large range, the white-lipped horned toad is susceptible to water pollution and deforestation.It is eaten in some parts of China and probably elsewhere across its range (van Dijk et al. 2004; Tran et al. 2010).
A species with a complex taxonomy, M. major (also Megalophrys major, Xenophrys major and originally Xenophrys gigas), been confused with and lumped with Leptolalax lateralis from the time of its first description (Boulenger 1908) and only just recently resolved as probably distinct species (Humtsoe et al. 2008).Sexual dimorphism and juvenile sizing has augmented this confusion.
Xenophrys major is a species of toad found in northeastern India, Burma, Thailand, Cambodia, Laos, Vietnam, and southern China.[2] It has recently been reported also from Bhutan.[3]
