(Figs. 1 A-G; 2A-F; 3)
Creagrura nigripes Townes, 1971: 7 [original description]; Gauld, 2000: 45 [taxonomic review]. Female holotype, Brazil (EMUS) [Entomology Museum, Utah State University, Logan, Utah, USA].
Diagnosis: This species can be distinguished by the combination of the following characters: mandible slightly twisted, with a wide ventral flap; scutellum with strongly raised lateral longitudinal carinae (Fig.1C);female with ovipositor very short, strongly curved downwards, being approximately 0.3 times as shorter as the hind tibia (Fig. 1A).

Geographical records: Brazil (Acre *, Amapá *, Amazonas*, Pará*, Rio de Janeiro, Roraima *), Costa Rica, Ecuador, Peru, Suriname (Fig. 3).
Remarks: The males and females of Creagrura nigripes analyzed showed differences in size and color patterns (Figs. 1 A-G; 2A-F), with variation in the spots on the propodeum (Figs. 1 C-G; 2C-F) and on the hind coxae (Figs. 1 A-B; 2A-B). In addition, the median longitudinal carinae (Figs. 1G; 2F) behind the posterior transverse carina (Figs. 1D; 2D) are strongly marked in the propodeum of some specimens (Figs. 1 C-G; 2C-F). The variations of these characteristics had already been mentioned by Gauld (2000), who analyzed 87 specimens from Costa Rica, and we also treat them here as intraspecific variations. However, these differences deserve to be evaluated more in-depth in the future, using also molecular data as they can reveal the presence of cryptic species. In addition, a broader sampling of specimens in other environments and biomes is needed to characterize these variations more robustly.
