Key to the Brazilian species of Charinus  (adapted from Miranda & Giupponi (2011) and Giupponi & Miranda (2016)) 

List of the described Brazilian species of Charinus  : C. brasilianus Weygoldt, 1972  ; C. montanus Weygoldt, 1972  ; C. asturius  Pinto-da-Rocha, Machado & Weygoldt, 2002; C. acaraje  Pinto-da-Rocha, Machado & Weygoldt, 2002; C. mysticus Giupponi & Kury, 2002  ; C. troglobius Baptista & Giupponi, 2002  ; C. eleonorae Baptista & Giupponi, 2003  ; C. vulgaris  Miranda & Giupponi, 2011; C. potiguar Vasconcelos, Giupponi & Ferreira, 2013  ; C. jibaossu Vasconcelos, Giupponi & Ferreira, 2014  ; C. caatingae Vasconcelos & Ferreira, 2016  ; C. iuiu Vasconcelos & Ferreira, 2016  ; C. brescoviti Giupponi  & Miranda, 2016; C. ricardoi Giupponi  & Miranda, 2016; C. bonaldoi Giupponi  & Miranda, 2016; C. guto Giupponi  & Miranda, 2016; C. carajas Giupponi  & Miranda, 2016; C. orientalis Giupponi  & Miranda, 2016; C. ferreus Giupponi  & Miranda, 2016; C. bichuetteae Giupponi  & Miranda, 2016; C. taboa Vasconcelos, Giupponi & Ferreira, 2016  ; and C. ruschii  Miranda et al. 2016. C. schirchii  (Mello- Leitão, 1931) is presently a species inquirenda, so it is not considered in the identification key and distribution map ( Fig. 31View FIGURE 31) ( Pinto-da-Rocha et al. 2002).
