Abstract: *Dryinus* Latreille is the most diverse genus of the subfamily Dryininae (Hymenoptera: Dryinidae), comprising approximately 300 described species worldwide (Martins & Melo, 2024). Of these, 111 species have been recorded from the Neotropical region, although this number is likely underestimated due to limited sampling efforts and the taxonomic complexity of the group (Martins & Perioto, 2021; Olmi & Virla, 2014). Species of *Dryinus* are parasitoids of Auchenorrhyncha (Hemiptera) (Guglielmino et al. 2013) and are important natural enemies in agricultural ecosystems, given the damage their hosts can cause to various crops (Virla et al. 2023; Martins et al. 2024). In Colombia, 11 species have been reported, with records concentrated mainly in the Amazonian and Andean regions (Olmi & Virla, 2014). The only species whose host has been identified is *Dryinus poecilopterae* (Richards) on *Poekilloptera phalaenoides* (L.) (Flatidae) (Guglielmino et al. 2013). Despite the country's high environmental heterogeneity and strategic position within the tropical Andes, knowledge of Dryinidae remains limited, and large areas remain poorly sampled. Consequently, the distribution of many species is still incompletely known. *Dryinus harpax* Olmi, 1993 is a Neotropical species previously known only from Costa Rica, herein, we provide the first confirmed record from Colombia, in the humid forests of Chocó-Darién in the Western Cordillera of the Andes, extending its known geographic distribution and contributing to the knowledge of Colombian Dryinidae.
