Description
Hyloxalus are small to moderate-size frogs, ranging from about 19 to 33 mm (0.7 to 1.3 in) in snout–vent length. Most species have cryptic, brown, gray, or black dorsal coloration, but some have conspicuous, bright colors (e.g., Hyloxalus azureiventris). A pale oblique lateral stripe is always present. Toe webbing is absent in most species but is present in some species and can even be extensive. Fingers bear narrow to moderately expanded discs.

Reproduction
Most species deposits their eggs in terrestrial nests and transport the tadpoles to pools on the forest floor or in backwaters of streams. Hyloxalus chlorocraspedus uses pools formed in fallen trees.
