2012 - A new species of Oecanthus and Oecanthus lineolatus Saussure, 1897 from Southern Brazil: species description, including phallic sclerites, metanotal glands and calling song (Orthoptera: Gryllid

We characterized and compared taxonomic features of two species of tree crickets Oecanthus in tobacco plantation and adjacent native trees and bushes at Southern Brazil. The marked differences between species included Oecanthus n. sp. with palegreen body, pale-yellow head, greenish-white eyes, file teeth number 32.8±1.2 (31–34, n = 6) and hindwings caudate. Oecanthus lineolatus is slightly darker as pale-green, with pale-green head, yellow eyes, hind femur variegated with translucent and pale-green, file teeth number 47±2.2 (42–51, n = 18) and hindwings non caudate. Both species also differ in calling song dominant frequency and temporal parameters, as well as in the morphology of metanotal gland.
