Both the known specimens of this species were captured using Winkler extractors. Both came from an Atlantic forest region, classified as Cfb on Köppen climate classification, with annual rainfall of 1,550 mm and average temperature of 17°C through the year (Alvares et al., 2014). According to IBGE (2019), these areas are defined as Floresta Ombrófila Densa Montana in association with secondary vegetation. This vegetation is found in altitudes ranging from 400 to 1.000 meters and generally has a thin soil layer, bearing trees of 20 meters height on average, with small leaves and thin trunks.
