Type material. Female holotype from Rio Grande, São Paulo, Brazil, 30.V.1951, V. Saar, deposited in IBSP (4083).

Diagnosis. Females of Corinna loiolai n. sp. are similar to those of C. regii n. sp. by the copulatory opening delimited both anteriorly and posteriorly by well defined margins, but differ by the secondary spermathecae separated from each other and by the posterior margin of copulatory opening nearly straight ( Fig. 105 ).
