This female looks like a pretty good match with the description and illustrations of Cremnops vulgaris in the genus revision by Tucker et al (2015): the vertical length of face and malar space are longer than any other of the species they included, its antennae have 35 (or 36?) articles (definitely less than 38 or more) the posterior end of the hind tibia has numerous small spines and the hind femur is closer to cylindrical than to the more swollen shape seen in other species.

However, the wings of this female are too dark to be able to compare forewing venation with that shown for C. vulgaris by Tucker et al, its red versus black surfaces are arranged a bit differently and I didn't catch any sight of the pattern of its propodeal dorsal sculpting or manage to reveal whether it had/lacked any scutal flanges.

If its identity as C. vulgaris can be confirmed by BG members with braconid expertise, than the species page for that could be added here. If it is that species, then I also strongly suspect a number of other recent submissions here are C. vulgaris as well, where the shape of both face and hind femur is clearly visible too: for example this male from TX shown by Victor Engel as well as the female from WA contributed by Nathaniel Green and Larry Reis' female from IA.

Exact location: the earliest flowering Isocoma pluriflora plant in the Isocoma patch just S of Dunes Drive at 2500ft E from the gravel driveway of the Dune Life Nature Trail parking area in White Sands National Park.
