Type material. Female holotype from Parque Nacional da Serra do Cipó [19°12'31.53"S 43°46'59.87"W], Minas Gerais, Brazil, II.1987, deposited in MNRJ (1775). Paratype. Brazil. Minas Gerais: (Parque Nacional da Serra do Cipó), [19°12'31.53"S 43°46'59.87"W], 1 female, II.1987 ( MNRJ 1775).

Etymology. The specific name is a patronym honoring our friend and colleague, arachnologist Regiane Saturnino, nicknamed “Regi”.

Diagnosis. Females of Corinna regii n. sp. resemble those C. loiolai n. sp. by the copulatory opening delimited both anteriorly and posteriorly by well defined margins, but differ by the secondary spermathecae touching each other and by the posterior margin of copulatory opening procurve ( Fig. 107 ).
