The type series consists of an adult male measuring 20 mm (0.79 in) and an adult female measuring 24 mm (0.94 in) in snout–vent length.[2] Another set of three males and three females shows a size range of 18.0–21.5 mm (0.71–0.85 in) for males and 21.4–23.5 mm (0.84–0.93 in) for females.[4] The head is triangular. The tympanum is absent. The canthus rostralis is marked. The limbs are slender with reduced webbing. The dorsum is granulose with small, scattered tubercles. The coloration is cryptic; the scapular area has an X-mark. The belly is immaculate.[2] The external margin of upper eyelid varies from weakly prominent to prominent.[4]
Its natural habitat humid rainforests at elevations of 80–1,100 m (260–3,610 ft) above sea level.[1][4] It occurs in leaf litter. It reproduces in bromeliads where the tadpoles develop. Dendrophryniscus berthalutzae is an uncommon species but continues to be collected on regular basis (notice though some specimens first reported as D. berthalutzae actually belong to Dendrophryniscus krausaedescribed in 2008[4]). It is threatened by habitat loss (deforestation).[1]
