03FE7019EB14C826C3C8FAC91A40ADA7.taxon	distribution	Distribution. The specimen was collected on the cargo ship S. S. Miraflores in the port of Galveston (Texas, USA). This vessel usually docked in this port carrying fruit shipments from Mexico, Central America, and the Caribbean Islands, therefore, the specimen could possibly have originated from any of these regions (Bordera et al. 2014). Furthermore, the black and orange coloration pattern with extensive white markings is more consistent with the pattern of Neotropical species than with that of Nearctic species. To date, no additional specimens of this species have been found.	en	Bordera, Santiago, Palacio, Edgard, Herrera-Flórez, Andrés Fabián (2025): The Neotropical species of Clistopyga (Hymenoptera, Ichneumonidae, Pimplinae).

03FE7019EB2DC81FC3C8FAF119BFAEBB.taxon	discussion	Remarks. This species was reported by Padua & Nunes (2017) from Sa ̃ o Paulo State (Brazil). In the diagnosis they mention, based in Graf (1985), that the occipital carina is raised and forming a dorso medial flange. This is a distinctive character of the C. chaconi species group, and this is clearly a mistake, since it does not appear in Graf’s description, nor can it be seen in the image provided in the work. This species lacks the raised occipital carina (Figs 24 D, 25 A).	en	Bordera, Santiago, Palacio, Edgard, Herrera-Flórez, Andrés Fabián (2025): The Neotropical species of Clistopyga (Hymenoptera, Ichneumonidae, Pimplinae).
