Abstract
SHARKEY, Michael-J. et al. Minimalist revision of Mesochorus Gravenhorst, 1829 (Hymenoptera: Ichneumonidae: Mesochorinae) from Área de Conservación Guanacaste, Costa Rica, with 158 new species and host records for 129 species. Rev. biol. trop [online]. 2023, vol.71, suppl.2, e53316. ISSN 0034-7744. http://dx.doi.org/10.15517/rev.biol.trop..v71is2.56316.
Introduction:
Species of Mesochorus are found worldwide and members of this genus are primarily hyperparasitoids of Ichneumonoidea and Tachinidae.
Objectives:
To describe species of Costa Rican Mesochorus reared from caterpillars and to a lesser extent Malaise-trapped.
Methods:
The species are diagnosed by COI mtDNA barcodes, morphological inspection, and host data. A suite of images and host data (plant, caterpillar, and primary parasitoid) are provided for each species.
Results:
A total of 158 new species of Mesochorus. Sharkey is the taxonomic authority for all.
Conclusions:
This demonstrates a practical application of DNA barcoding that can be applied to the masses of undescribed neotropical insect species in hyperdiverse groups.
