In recent years, the study of wild silkmoths (Lepidoptera: Saturniidae) has increased exponentially due to the intense sampling effort and the use of molecular evidence for species delimitation, which led to the description of numerous new taxa especially from the Neotropic. Given these rapid advances, the checklist of the Colombian Saturniidae needs to be updated to cover the taxonomy, distribution, and diversity of these moths in the country. After an extensive review of literature, data repositories, and collections, an updated and comprehensive list of Saturniidae from Colombia is presented, including their occurrence status in each Colombian department. The checklist includes 7 subfamilies, 55 genera, and 790 taxa (766 in species rank) of Saturniidae in Colombia. Current distribution data show that the genusWinbrechlinia, the subgenus Darylesia, 379 species, and 18 subspecies are endemic to Colombia. Moreover, a dichotomic key to the Colombian subfamilies is provided. A few taxonomic changes are proposed based on a thorough taxonomic revision of the Colombian taxa. This revision also addresses the issue of outdated species names reported in the first checklist of Colombian Saturniidae (Amarillo-Suárez 2000) and excludes old records of taxa that are considered dubious for Colombia based on new evidence. By presenting an updated list of Colombian species, including the newly described taxa, this study aims at eliminating confusion stemming from outdated names and provides a useful resource for researching and conservating Saturniidae in Colombia. We wish to offer a common reference for future studies on the biodiversity and biogeography of moths in the Neotropical realm.
