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. 31 ) ( Pinto-da-Rocha et al. 2002).
