The distribution of the freshwater crab Fredius reflexifrons (Ortmann, 1897) (Brachyura, Pseudothelphusidae) in an Environmental Protection Area of the Planalto da Ibiapaba, Northeastern Brazil

An observational record of Kingsleya attenboroughi Pinheiro & Santana, 2016 (Decapoda, Pseudothelphusidae), an endemic species from the Chapada do Araripe, southern Ceará, Brazil

“…Due to the scarcity of distributional, biological, and ecological data on K. attenboroughi, the conservation status of this species cannot yet be assessed using IUCN criteria, and it is Data Deficient (Acevedo-Alonso and Cumberlidge 2021). Santos et al (2020b) suggested that the channeling of water resources is partial in the areas where F. ibiapaba occurs in the Ibiapaba plateau. However, in Gameleira stream, K. attenboroughi is subjected to an almost complete channeling of its flow for domestic and agricultural use.…”

“…We used the active search method to collect the crabs, from 7:00 pm to 1:00 am, always with four researchers. In addition, we used traps made from PET bottles, which we distributed along the streams (adapted from Santos et al 2020b).…”
