Abstract

A faunal study for the order Phasmatodea of the Chicaque Natural Park is presented, including a list of species found, descriptions, redescriptions, and biological notes. A total of nine species were found and studied; two new genera: Ramandeun new genus, Nubilophasma new genus, and four new species: Atrato¬morpha jorgei new species, Isagoras franciscoverai new species, Nubilophasma chicaquensis new genus and new species, and Ramandeum coronatum new genus and new species are described. The description of the eggs of the new taxa, of the previously unknown eggs of Paraceroys quadrispinosus (Redtenbacher, 1906), and the redescription of the eggs of Libethra rabdota Stål, 1875, and Libethra inchoata Brunner von Wattenwyl, 1907 are provided. Additional comments on the ecology and morphological variation of the reviewed taxa are included. Finally, further studies on the stick insect fauna of the Colombian Andes are discussed and recommended to provide more information to broaden the understanding of the species that inhabit this complex mountain system.

Resumen

Se presenta un estudio faunístico para el orden Phasmatodea del Parque Natural Chicaque, inclu¬yendo un listado de especies halladas, descripciones, redescripciones, huevos y notas biológicas. Un total de nueve especies fueron halladas y estudiadas, dos géneros nuevos son descritos: Ramandeun nuevo genero y Nubilophasma nuevo genero y cuatro nuevas especies: Atratomorpha jorgei nueva especie, Isagoras francis¬coverai nueva especie, Nubilophasma chicaquensis nuevo genero y nueva especie y Ramandeun coronatum nuevo genero y nueva especie. La descripción de los huevos de los nuevos taxones, y los huevos desconoci¬dos de Paraceroys quadrispinosus (Redtenbacher, 1906), y la redescripción de los huevos de Libethra rabdota Stål, 1875, and Libethra inchoata Brunner von Wattenwyl, 1907 son proporcionados. Se incluyen comenta¬rios adicionales sobre la ecología y variación morfológica de los taxones revisados. Finalmente, se discute y sugieren más estudios sobre la fauna de insectos palo de los Andes colombianos que proporcionen mayor información para ampliar la comprensión de las especies que habitan este complejo sistema montañoso.
