A new species of Coelosis is described from the Macuira Mountains, Guajira Peninsula, northern Colombia. A character comparison between this new and other previously known Colombian species in the genus is presented. A key for the identification and distributional map for Colombian species of Coelosis is provided, as well as a key for the genera included in the tribe Oryctini in Colombia.
Una nueva especie de Coelosis es descrita de la Serranía de la Macuira en la Peninsula de la Guajira
en el extremo norte de Colombia. Se ilustran los caracteres diagnósticos y se compara la nueva especie con las especies previamente reportadas para Colombia. Se provee una clave para la identificación y un mapa de distribución de las especies de Coelosis en el país al igual que una clave para los géneros de la tribu Oryctini en Colombia.

The genus Coelosis is a Neotropical dynastine group of mainly nocturnal forest beetles that can be collected at lights (
The purpose of this work is to describe a new species of Coelosis from a tropical dry forest in the protected area of Macuira, Guajira Pensinsula, to provide new biological data and distribution records for other species Coelosis, and to provide diagnostic characters and illustrations for all three Colombian species in the genus Coelosis as well as a key to the genera of Oryctini from Colombia.
Internal and external morphological characters were studied using a dissecting microscope (6.5–40.0×). For measurements, an ocular micrometer was used. Internal sclerotized structures were dissected after relaxing the specimen in hot (75 °C) water. Heavily sclerotized parts were soaked in a 15 % solution of potassium hydroxide and neutralized in a 15 % solution of acetic acid. Genitalia were card-mounted or placed in a glycerin‒filled vial beneath the specimen.
Specimens were characterized using body length, puncture density, setation, and color as described in
138 specimens were reviewed and label data were obtained from the following Colombian collections except where noted otherwise (curators in brackets):

(3). Holotype labeled “Colombia, La Guajira, Uribia, PNN La/Macuira Corregimiento Nazareth/Kajashiwoü, 12°11'37.9”N; 71°21'30.1”/W. WGS84, 70 m. Manual.19.ix.2014/C. Medina” [
Coelosis wayuorum sp. n. can be separated from the other Colombian Coelosis by the following characters: maxilla with lateral sclerite pronounced (Fig.
Holotype male (Fig.
(Fig.
Paratype (1). Similar to allotype except for the following: body length 25.5 mm; width 13.0 mm.
The specific epithet wayuorum refers to the Wayuu indigenous group inhabiting the Guajira Peninsula.
Coelosis wayuorum sp. n. is known only from one locality in Macuira National Park, Colombia (Fig.
Three specimens collected in September 2014, during the dry season.
The type material was collected at night with lights during the dry season.

We thank Hernando García and Roy González from the Alexander von Humboldt Biological Resources Institute, and Robinson Díaz from National Natural Parks, for the organization of the expedition to Macuira. For their warm welcome in their land, we thank Alberto González and all the people from Kajashiwoü indigenous reserve within the Macuira National Natural Park. John W. Miles (Center for Tropical Agriculture Forage Breeder) was of great help with language editing and proofreading.
