Incilius leucomyos

Adult males measure 51–68 mm (2.0–2.7 in) and females 55–96 mm (2.2–3.8 in) in snout–vent length. The body is robust and the head is slightly wider than it is long. The snout is nearly rounded but has a protruding tip in dorsal view. The tympanum is distinct but comparatively small. The canthal, supra-orbital, post-orbital, supra-tympanic, and parietal crests are all well-developed. The parotoid glands are sub-triangular. The limbs are relatively long. The fingers are long and slender and without enlarged tips and webbing. The toes are also long and slender but have some webbing. Skin is dorsally rugose and ventrally granular to strongly granular. The dorsal coloration is mostly yellow ocher but with buff mid-dorsal area. There is a rust-brown inter-ocular bar, rust-colored crests, and pale rust-colored post-ocular blotches.[3]

Its natural habitats are lowland moist forests as well as premontane and lower montane wet forests; its altitudinal range is from near sea level to 1,600 m (5,200 ft) above sea level. The tadpoles develop in streams. It is threatened by habitat loss caused by landslides (impacting streams) as well as from farming, logging, and human settlements. It occurs in some protected areas, including the La Muralla and Pico Bonito National Parks.[1]
