Description

edit

The adult male frog measures 16.2–19.0 mm in snout-vent length and the adult female frog 17.1-23.6 mm. This frog has no webbed skin on any of its four feet. The skin of the dorsum is mottled with lighter marks. Some frogs also have black marks. There is a black line from the shoulder to the cloaca. Larger males have darker bellies than smaller males, and older females have more spots on their throats than younger females. Female frogs have white bellies. The male frog's testicles are white in color.[4]

Etymology

edit

Scientists gave this frog the Latin name anthracinus for the coal-black color of its stripes.[4][2]

Young

edit

Scientists think that the female frog lays eggs on the ground and that the adult male frogs carry the tadpoles to streams.<ref name="iucn status 16 November 2021">

Habitat

edit

Its natural habitats are páramo, very humid montane forest, and lower humid montane forest. It appears to have declined dramatically, possibly due to chytridiomycosis. It is also threatened by habitat loss, which scientists attribute to agriculture, development, human transportation routes, and pyroclastic events.[1]

The frog's range includes some protected parks, for example Parque Nacional Sangay, Parque Nacional Rio Negro Sopladora, Parque Nacional Cajas, and Siete Iglesias Municipal Ecological Conservation Area.[1]
