A new species of Ripipteryx from the Ecuadorian Andes (Orthoptera: Tridactyloidea: Ripipterygidae)

A new species of Ripipteryx Newman (Orthoptera: Tridactyloidea: Ripipterygidae) is described from a fragment of primary Andean forest on the slopes of the extinct Pasochoa volcano in Pichincha Province, northern Ecuador. Ripipteryx pasochoensis sp. nov. is distinguished from congeners by the morphology of the male terminalia, particularly the structure of the subgenital plate. Based on colouration, modification of the subgenital plate and structure of the phallic complex, the new species is assigned to the Forceps Group and appears most closely related to Ripipteryx processata Günther. Keys to the species groups of Ripipteryx and to the species of the Forceps Group are provided, and a preliminary subgeneric classification appended.
