Cycloramphus boraceiensis is an endemic frog of the Atlantic Forest of southeastern Brazil. Although relatively easy to find and distributed over a well-sampled region in southeast Brazil, little is known about its natural history, breeding activity, and vocal repertoire. In the present study, we provide new information on pre-and post-hatching larval development, describe new traits of their advertisement calls, describe its aggressive call for the first time, and provide new data about adults’ and tadpoles’ defensive strategies. We found individuals on rocks on cascaded streams or within rocky crevices along streams inside forested habitats. Males concentrated their calling activity between 03:00 and 5:00 h and between 19:00 and 23:00 h. The aggressive call is shorter than the advertisement call and has greater variation in the number of pulses and emission rate. The eggs hatched at Gosner’s stage 25, after seven and eleven days of oviposition, and tadpoles took between eight and ten days to complete metamorphosis. This study contributes to the knowledge of the Flattened Waterfall Frog by filling natural history gaps that can be useful for species conservation and bringing attention to traits that still need further investigation, such as color plasticity and microhabitat selection. 

Cycloramphus boraceiensis es una rana endémica del Bosque Atlántico del sureste de Brasil. A pesar de que es relativamente fácil de encontrar y se distribuye en una región bien muestreada en el sureste de Brasil, se sabe poco sobre su historia natural, actividad reproductiva y repertorio vocal. En el presente estudio, estudiamos una población de C. boraceiensis y proporcionamos nueva información sobre el desarrollo larvario antes y después de la eclosión. Describimos también nuevos rasgos de sus vocalizaciones de anuncio, además realizamos por primera vez la descripción de su vocalización agresiva el cual aporta nuevos datos sobre el mecanismo de defensa de adultos y renacuajos. Encontramos individuos sobre rocas en arroyos en cascada y dentro de grietas rocosas. Los machos concentraron su actividad de canto entre las 03:00 y las 5:00 h, y entre las 19:00 y las 23:00 h. La vocalización agresiva es más corta que la vocalización de anuncio y tiene una mayor variación en el número de pulsos y en la tasa de emisión. Los huevos eclosionaron en la etapa 25 de Gosner, después de siete y doce días de la oviposición, y los renacuajos tardaron entre ocho y diez días en completar la metamorfosis. Este estudio contribuye al conocimiento de la rana de cascada aplanada al llenar los vacíos de la historia natural que pueden ser útiles para la conservación de especies y llamar la atención sobre los rasgos que aún necesitan atención, como la plasticidad del color y la selección del hábitat.
