Corinna zecarioca n. sp.

Figs. 58–62

Type material. Male from Gávea [22°59'10.35"S 43°14'42.60"W], Rio de Janeiro, Rio de Janeiro, Brazil, Wenskoski, E.H., deposited in MNRJ (06447). Paratype: Brazil. Rio de Janeiro: Petrópolis [22°30'16.70"S 43°10'56.38"W] (Estação Rio, 850m), 1 female, 2.XI.1945, H. Sick ( AMNH).

Etymology. The specific name is a noun in apposition referring to Walt Disney’s character “José Carioca” or, shortly, “Zé Carioca”, created in 1942. The green parrot Zé Carioca is a friend of Donald Duck and the comic books are still popular among Brazilian kids, especially those born in the city of Rio de Janeiro, the Cariocas.

Diagnosis. Males of Corinna zecarioca n. sp. resemble those of C. aechmea n. sp. and C. jecatatu n. sp. by the bifurcated RTA, but can be recognized by the stout, sub-squared median process in the prolateral surface of RTA and by the tegular process positioned at the base of embolus ( Figs. 58–59 ); females of Corinna zecarioca n. sp. resemble those of C. tranquilla n. sp. by secondary spermathecae separated from each other by more than its diameter, but differ by these spermathecae being globular instead of ovoid ( Figs. 60–61 ).
