[4][5] The species' Latin name refers to F. Carlos Lehmann V.[6] The female frog lays eggs in the leaf litter and the male frog carries the tadpoles to streams with slow-flowing water for further development.

[6] Its natural habitats are very humid montane forest, but it has also been found in open fields and very modified areas.

[4] The frog's range includes several protected parks, including Parque Nacional Sumaco Napo-Galeras, Reserva Ecológica Cayambe-Coca, and Reserva Natural Comunitaria El Manantial Florencia.

[1][6] Hyloxalus lehmanni is common in Colombia, but has dramatically declined in Ecuador, possibly due to chytridiomycosis.

Also habitat loss, introduction of alien predatory fish, and pollution are threats.
