Chiasmocleis magnova was described with only two female individuals from the Allpahuayo Mishana National Reserve and surroundings in the Loreto region, Peru. The presence of large eggs in the holotype led the descriptors to assume that this species reproduces with direct development. After the description, records emerged to the north and south of the Amazon River; however, these records lacked photographs and most also lacked population information. This motivated us to learn more about their reproduction, distribution, and abundance by habitats. To this end, we captured and placed a pair of C. magnova in an aquaterrarium to assess their eggs and tadpoles. In parallel, we assessed bromeliads in transects in search of reproductive pairs to evaluate their oviposition. We recorded visual encounters for 460 hours in white sand forests, low hill, middle, and low terrace forests in order to e...
