This study aims to expand the knowledge of angel insects in Colombia. A new species of Centrozoros Kukalová-Peck & Peck, 1993 (Zoraptera: Spiralizoridae) from a high elevation area of Colombia is described. Centrozoros mesenia Lima, Oliveira & Rafael sp. nov. was collected from Andean cloud forest at the Mesenia-Paramillo Nature Reserve. The new species is described based on a male specimen and is characterized mainly by the presence of a leaf-like sclerotized projection at the base of the aedeagus. We present digital images of the new species and a distribution map of the species of Zoraptera registered for Colombia until now.

A new species of Lusius Tosquinet, 1903 (Hymenoptera: Ichneumonidae: Phaeogenini) is described from the northwestern Andes of Colombia, and additionally, the geographic distribution of Lusius ferrugineus Graf, 2000 is expanded to Bahia and Rio Grande do Sul states, Brazil. New comparative diagnoses, distribution maps, and an illustrated key to Neotropical species are also provided.
