The Neotropical Anomaloninae is one of the poorly studied groups within Ichneumonidae, currently with 17 genera occurring on this biogeographical region (^{Fernandes and Diaz, 2019}) of which just Podogaster^{Brullé, 1846} has species recorded to Colombia (^{Gauld and Bradshaw, 1997}; ^{Yu et al., 2016}). Herein we report for the first time to Colombia the genera Aphanistes^{Förster, 1869} and Habronyx Förster, 1869; we also report Castrosion Gauld & Bradshaw, 1997 and Ophiopterus Brullé, 1846 to Peru; and Anomalon^{Panzer, 1804} to Trinidad and Tobago, besides the first record of three species of Anomalon to Brazil, Peru, and Trinidad and Tobago.

The Colombian specimens examined in this study were collected using manual collection and entomological nets during an inventory carried out in the Colombian Andes, more specifically at the Mesenia-Paramillo nature reserve, department of Antioquia, Colombia (5°29'46.1"N and 75°53'20.5"W) in February, March, April and December 2019. These specimens were deposited in the Universidad de los Andes (UNIANDES) entomological collection (curator: Emilio Rialpe) in Bogota under ANLA collection permit 1177 of specimens of the biological diversity. New distribution records for Brazil, Peru, and Trinidad and Tobago have been incorporated to this manuscript from the observation of specimens belonging to the following institutions (curators in parentheses): MUSM: Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Perú (Gerardo Lamas), RMNH: Naturalis Biodiversity Center, Leiden, Netherlands (Frederique Bakker) and LRRP: Instituto Biológico, Ribeirão Preto, São Paulo, Brazil (Nelson W. Perioto).

The information contained in the "Examined material" sections corresponding to the specimen label is organized by country and major geographic regions (regions, states, departments, district, commune, parish or provinces, according to each country). Different collecting events are separated with semicolons. Label data was rearranged, including only the information provided, in the following order: locality, coordinates in sexagesimal degrees, elevation, date, collecting method, collector, and any other information included. Abbreviations were completed; and, if other language than English was employed, it was translated. New distribution records are indicated by an asterisk (*). General morphological terminology follows ^{Broad et al. (2018)}. Photographs were prepared using a Canon EOS 5D Mark IV and Canon EF 100mm f/2.8 IS USM macro lens for the Colombian specimens, and Canon EOS T3 and Canon EF-S 60 mm macro lens for the Peruvian specimens. All images were later prepared with Adobe Photoshop® (v. 20.0.5).

Comment. This is the first record of the genus Anomalon as well as the species A. sinuatum to Trinidad and Tobago. In Peru, A. sinuatum was only recorded from Ica and Lima departments (^{Alvarado et al., 2014}), at the center of the Pacific coastline; herein is recorded to Tumbes, the northernmost department of Peru, and found in Pacific tropical and Equatorial dry forest. In Brazil, A. sinuatum was only recorded to Amazonas state (^{Fernandes et al., 2020}), and this is the first record for São Paulo state.
