Abstract The monotypic genus Pilobaloderes Kulzer (Pimeliinae: Praociini), endemic to Peruvian Andes, is revised. Based on examination of recently collected specimens, we describe the female of the type species and a new species, Pilobaloderes aquilonarius sp. nov., emphasizing dimorphic and diagnostic characters of the protibiae. A redescription of the genus and its species, with remarks about sexual dimorphism are included. Habitus photographs, illustrations of protibiae, genital features, and a distribution map are also presented. Pimeliinae (Pimeliinae Praociini, Praociini , Praociini) Andes revised specimens sp nov nov. protibiae included photographs features presented

Abstract The predation capacity of protonymphs and adults of E. emanus on eggs, larvae, protonymphs and adults of O. beeri was evaluated under controlled conditions of temperature and humidity. According to the tests, the adult females had a higher predation capacity (mean = 23.18 larvae) than the protonymphs (mean = 11.15 larvae) and the adult males (mean = 8.05 larvae). Both stages of development of E. emanus consumed higher amounts of larvae and protonymphs, while their consumption of eggs was minimal.

Resumen Se evaluó la capacidad de predación de protoninfas y adultos de E. emanus sobre huevos, larvas, protoninfas y adultos de O. beeri en condiciones controladas de temperatura y humedad. De acuerdo a los ensayos, las hembras adultas tuvieron mayor capacidad de predación (media = 23.18 larvas) que las protoninfas (media = 11.15 larvas) y los machos adultos (media = 8.05 larvas). Ambos estados de desarrollo de E. emanus consumieron mayores cantidades de larvas y protoninfas, el consumo de adultos machos fue menor, mientras que el consumo de huevos fue mínimo.

Abstract: The distribution of Epitragini tribe in Peru is updated from the review of Peruvian entomological collections and the compilation of previously published records. New records and habitat preferences for eight species of the genera Epitragopsis, Parepitragus and Phytophilus are presented. Also available records for five species not found in Peruvian collections and distribution maps are provided.

Resumen: La distribución de la tribu Epitragini en Perú se actualiza a partir de la revisión de colecciones entomológicas peruanas y la recopilación de registros previamente publicados. Se presentan nuevos registros y preferencias de hábitat para ocho especies de los géneros Epitragopsis, Parepitragus y Phytophilus. También se proporcionan registros disponibles para cinco especies que no han sido halladas en colecciones peruanas y mapas de distribución.
