Ameerega simulans is a small to medium-sized species of poison dart frog that lives in Peru in Puno described in 1998.

[2][3][4] It can be found at an elevation of 400–600 m.[4][1] Females with average size of 23.6–27 mm are slightly larger than males that measure on average 18.9–22.4 mm (a sign of sexual dimorphism).

[4] This frog lives in lowland and submontane rainforests, where it has been observed on the leaf litter.

After the eggs hatch, the male frog carries the tadpoles to water.

It suffers from localized habitat loss in some parts of its range, usually associated with agriculture and livestock cultivation.
