São Paulo: Barueri [23°30'40.69"S 46°52'36.39"W], 1 female, 16.I.1966, K. Lenko, ( MZUSP 5591); 1 male, 06.XII.1964, K. Lenko ( MZUSP 3821); Osasco [23°31'54.09"S 46°47'23.72"W], 1 male and 1 female, 15.IV.1938, F.Lane ( MZUSP 12525); São Paulo [23°32'56.19"S 46°38'19.74"W], 1 female, 11.VII.1937, J.R. Mattos, ( IBSP); 1 male, I.1960 ( IBSP 1480).

Etymology. The specific name is a noun in apposition referring to the classic hick character “Jeca Tatu”, created by the Brazilian writer Monteiro Lobato for his masterpiece “Urupês”, first published in 1918. The character was based on the countrymen from the countryside of state of São Paulo and was intended to denounce the poor living conditions of those Brazilians.

Diagnosis. Males of Corinna jecatatu n. sp. resemble C. aechmea n. sp. and C. zecarioca n. sp. by presenting the RTA bifurcated, with a large median process in the prolateral suface; differ from those of C. aechmae n. sp. by the absence of a rounded tegular apical projection and from those of C. zecarioca n. sp. by the longer RTA median process ( Figs. 54–55 View FIGURES 50 – 57 ); females differ from those of other species with secondary spermathecae separated by less than one diameter and copulatory opening median by posterior margin of copulatory opening straight ( Figs. 56–57 View FIGURES 50 – 57 ).
