Based on literature review, curatorial work in national and international collections, information available on online databases, and field work conducted from 2017 to 2022, we provide the first checklist for the family Notodontidae in Colombia. A total of 515 species (51 endemics), 122 genera, 7 subfamilies as well as 108 new records for Colombia are presented. These data position Colombia as the country with the third highest diversity of prominent moths in the world, based on current knowledge. Furthermore, 239 known hostplants are listed for 91 species. The distribution map of the family shows the highest concentration of national records in the Andean and Pacific regions. Future surveys in less explored zones, long-term monitoring, expansion and maintenance of biological collections, and working collaboratively with communities will surely increase the known diversity as well as the conservation of prominent moths in Colombia.

A new species of the genus Polypoetes Druce, 1885, Polypoetes milleri spec. nov. from Colombia is described. We provide diagnostic characters for the species, photographs of the adults and genital structures of both sexes. Additionally, we confirm a new host plant for the subfamily Dioptinae, Quararibea cordata (Malvaceae), commonly known as “zapote”.

We present the first list focused on Mimallonidae from a Colombian biological collection, the Museo Javeriano de Historia Natural “Lorenzo Uribe, S.J.” (MPUJ) of the Pontificia Universidad Javeriana in Bogotá. We report nine species and seven genera, and we highlight the museum’s hidden treasures: the first known female of Bedosiallo moengus (Schaus, 1928) and a new species, Gonogramma faguai nov. sp.

Based on the review of literature and biological collections, information retrieved from public online databases, and from fieldwork conducted between 2015 and 2020, we provide more than 3500 occurrence records and an updated checklist of Colombian Saturniidae, annotated with distribution data for all species. In the first checklist of Colombian saturniids published two decades ago, a total of 184 species were cited; in the current update the number has risen to 653 species/subspecies classified in 55 genera, representing all six recognized Neotropical subfamilies. The Andean and Pacific regions are the richest, accounting for about three quarters of all species listed herein. We call attention to the fact that for most speciose saturniid genera in the Neotropics, there remains a significant need for further taxonomic and systematic research with objective and integrative approaches. Likewise, it is necessary to continue the study of Saturniidae moths in Colombia, strategically increasing the sampling efforts in specific under-sampled natural regions to further document the diversity of this family in the country.

Se presenta una lista anotada de especies de las familias Bombycidae, Saturniidae y Sphingidae recolectadas en el Parque Nacional Natural Utría, Chocó, Colombia. El muestreo se realizó en cuatro hábitats del parque durante 31 días, utilizando una trampa de luz con un bombillo de vapor de mercurio. Se registraron 35 especies: 19 Saturniidae, 15 Sphingidae y 1 Bombycidae. Por primera vez para el departamento del Chocó se registran 18 especies. Se resaltan los registros de las especies Syssphinx chocoensis, endémica del Chocó colombiano, Manduca dalica dalica depositada por primera vez en una colección colombiana y el quinto instar de Isognathus scyron. El número de individuos recolectados concuerda con la hipótesis de la fobia lunar. El presente trabajo es la primera aproximación a la diversidad de estas familias para el Parque Nacional Natural Utría.
