Looks like a "velvet ant" (Hymenoptera: Mutillidae).
Identification by: "...the lack of petiole nodes, which are present on all ant species. In addition, the mesosomatic (thoracic) segments are completely fused and have at most two segments. The metasoma (abdomen) contains six visible terga (dorsal surface of any body segment) and a "felt line" of dense, closely appressed hairs is located laterally on the second metasomatic tergum" (from: http://entnemdept.ufl.edu/creatures/misc/wasps/mutillidae.htm)
Picture not perfect, but closely resembles Timulla sp. (Hymenoptera: Mutillidae). By the way, Velvet Ants are not true ants. They are wasps. Hope this helps, and try not to handle them.
If you are studying ants and found this specimen in your collection please remove it because it is not an ant. Refer to features of Family Formicidae for more information.
Yes, this is a mutillid female. When you ask identification of insects, please attach the locality where the specimens were collected so that we have some possibility to identify the at genus level.
