Two new species of Golofa Hope, 1837 (Coleoptera : Melolonthidae : Dynastinae) from the colombian andes, south America.

Objective: To describe two new species of the genus Golofa. Scope: To expand the list of species of the tribe Dynastini for Colombia. Methodology: We reviewed the specimens of the genus Golofa deposited in the Colección Familia Pardo-Locarno CFPL-COL, establishing differences between the species already identified and the specimens type used for the description of the two new species reviewed in this manuscript. Main results: We described two new species of Golofa Hope, 1837, showing photographic records with diagnostic value. The number of species for Colombia is increased to nine, thus, the synopsis of species is formed as follows: Golofa aegeon Drury, 1773, Golofa antiqua Arrow, 1911, Golofa claviger Linnaeus, 1771, Golofa eacus Burmeister, 1847, Golofa paradoxa Dechambre, 1975, Golofa pelagon Burmeister, 1847, Golofa porteri Hope, 1837, Golofa farallonensis n. sp. Pardo-Locarno & Villalobos-Moreno y Golofa veliae n. sp. Pardo-Locarno & Villalobos-Moreno. Conclusions: These records ratify the Tropandean distribution of the group, evidencing the little biological and biogeographic knowledge of this group in Colombia. The results indicate a great diversity of the genus in the country, so that, the study of species distribution is recommended.
