Comprehensive DescriptionRead full entry
Atelopus andinus are slender toads with type male of this species reach 28 mm and type female 34.9 mm in terms of total length. The head is approximately as long as it is wide. Total leg length is slightly shorter than snout vent length. And the foot is about a third of the snout vent length. Their skin is highly granular with a spiny texture that is concentrated on their eyelids, dorsolatera area, and posterior end. The limbs are less granular. Otherwise the description is similar to that of Atelopus spumarius (Rivero 1968).
Atelopus andinuscan be differentiated from other Atelopus species by its grandular skin and color pattern. Specifically, Atelopus andinus is differentiated from Atelopus spumarius by having more dense tubercles, especially on the eyelid, dorsolateral area, and posterior end. Additionally, the dorsolateral band and dorsal spots are tan instead of ranging from green to green-yellow in Atelopus spumarius (Rivero 1968).
Atelopus andinus has a black dorsum with a tan dorsolateral band and tan dorsal spots (Rivero 1968). They exhibit bright colors, which serve as visual warnings that these frogs do secrete toxins in their skin (Lotters 2003).
