A new subfamily of the planthopper family Ricaniidae Amyot et Serville (Homoptera, Fulgoroidea)

摘要

Pharsalinae subfam. n. is erected in the family Ricaniidae Amyot et Serville for two monotypical genera Pharsalus Melichar, 1906 and Silvanana Metcalf, 1947 distributed in South America. The members of the new subfamily are characterized by the submacroptery, simple radius and anterior cubitus of the fore wing, the style capitulum bearing a lateral tooth, and the subrectangular (in lateral view) gonoplacs with partly separated third lobes and without marginal teeth. Pharsalus repandus Melichar, 1906 is recorded from Uruguay for the first time.
