RESUMEN
Darwin wasps (Hymenoptera: Ichneumonidae) are parasitoids and a natural enemy of a wide range of holometabolous insects and spiders and are considered one of the largest families in the animal kingdom. Unfortunately, there are great gaps in the knowledge of this family in Colombia. This study aims to expand the knowledge of Darwin wasps in Colombia, through new records for the country and especially the department of Antioquia. We present the diagnosis and digital images of the recorded species, and we describe for the first time the males of three species of Dolichomitus Smith, 1877: D. mariajosae Araujo & Pádua, 2020; D. menai Araujo & Pádua, 2020; D. orejuelai Araujo & Pádua, 2020.

Two new Darwin wasp species of Eiphosoma Cresson, 1865 (E. nigroandinum Fernandes sp. nov. and E. merceae Fernandes sp. nov.) are described from the northwestern Andes of Colombia. Furthermore, we propose the establishment of a new species-group, E. nigroandinum species-group, to encompass these newly described species. Additionally, we expand the geographical distribution of Eiphosoma vitticolle Cresson, 1865, and complement the findings with a map and digital images.

Dolichomitus Smith is a widely distributed pimpline genus with more than seventy known species. There are eight species previously reported from South America: D. annulicornis (Cameron), D. bivittatus Townes, D. hypermeces Townes, D. jatai Loffredo & Penteado-Dias, D. longicauda Smith, D. megalourus (Morley), D. moacyri Loffredo & Penteado-Dias and D. zonatus (Cresson). In this paper, we describe five new species: D. mariajosae Araujo & Pádua, sp. nov., D. menai Araujo & Pádua, sp. nov., D. orejuelai Araujo & Pádua, sp. nov., D. pimmi Araujo & Pádua, sp. nov., and D. rendoni Araujo & Pádua, sp. nov. All have been collected in cloud forests in the Colombian tropical Andes. An illustrated key to the South American species of the genus is also provided.
RESUMEN
Pimpla Fabricius is one of the largest genera within the subfamily Pimplinae, whose species are idiobiont endoparasitoids of Lepidoptera pupae and prepupae. A total of 13 species are known from Colombia, but they are difficult to identify because of their morphological complexity. Herein we record for the first time in Colombia the following species: P. albomarginata Cameron, P. caerulea Brullé and P. sumichrasti Cresson. Furthermore, we present the first identification key to female and male of the Colombian species, along with diagnoses, biological notes and images in vivo.
