Description

Megaelosia lutzae are relatively large frogs: two males in the type series measure 88–93 mm (3.5–3.7 in) and a female 90 mm (3.5 in) in snout–vent length. Dorsolateral skin has many large granules. The snout acuminate in dorsal view and rounded in profile. Canthus rostralis is evident and straight.[4]

A single tadpole in Gosner stage 42 (towards the completion of metamorphosis) measured 130 mm (5.1 in) in total length.[4]

Habitat and conservation

The species' natural habitats are streams in primary forest. During daytime these frogs are found on emergent rocks in shallow places in streams. They lay the eggs under large rocks in moderately-sized forest streams.[1]

The Itatiaia National Park is well protected, and there are no known significant threats to this species.[1]
