title: Three new species of the genus Ripipteryx from Colombia (Orthoptera, Ripipterygidae).
abstract: Three new species of Ripipteryx Newman (Orthoptera: Tridactyloidea: Ripipterygidae) are described from Colombia; namely Ripipteryxdiegoi sp. n. (Forceps Group) and Ripipteryxguacharoensis sp. n. (Marginipennis Group) from Parque Nacional Natural Cueva de los Guacharos in Huila, and Ripipteryxgorgonaensis sp. n. (Crassicornis Group) from Parque Nacional Natural Gorgona in Cauca. Ripipteryxdiegoi sp. n. is characterized by the antennae black with white spots on flagellomeres 3-7, male subgenital plate with median ridge forming a bilobed setose process, epiproct produced laterally near its base and phallic complex with virga thickened distally and not reaching beyond the membrane. Ripipteryxguacharoensis sp. n. is characterized by the antennae thick with white spots present dorsally on flagellomeres 1-4 and 8, epiproct narrow and triangular, uncus reduced and lacking a distal hook, phallic complex with a concave ventral plate and a dorsal elevation in the middle extended to the virga, and the virga itself with two small projections basally. Ripipteryxgorgonaensis sp. n. is characterized by the epiproct with a lateral notch, antennae with a white dorsal spot on flagellomere 1 and flagellomeres 4-7 entirely white. The antennal color pattern of Ripipteryxgorgonaensis sp. n. strongly resembles that of Ripipteryxatra but differs from the latter in the absence of any significant morphological modification of the flagellomeres.
