Two juvenile specimens of Charinus were found in two Brazilian States: Charinus sp. 1 from Tocantins (Porto Nacional, Luzimangue) and Charinus sp. 2 from Ceará (Gruta Ubajara) ( Fig. 13 ). They could not be identified at species level, but we will try to capture adult individuals in future expeditions.
