Xenohyla eugenioi is a species of tree frog in the Hylidae family native to northeastern Brazil in ecotones between the Atlantic Forest and caatingas.

It has been found in the Brazilian states of Bahia[2] and Sergipe,[3] approximately 1,000 km away from the other species in its genus, Xenohyla truncata.

Like its relative, this frog spends the day hiding in bromeliads, emerging at night to hunt and forage.

[1] This frog is not endangered, but scientists note that there may be some threat from the collection of bromeliad plants and habitat loss associated with agriculture, livestock grazing, and logging.

Additionally, the species prefers to inhabit agrestes, and breeds in temporary pools formed by rainwater.
