DIAGNOSIS A very small, yellow member of the flavens group whose major is marked by its strongly curved propodeal spine (as though the tip had “melted” backward); long scapes, which reach the occipital corners; all of the sculpturing on the anterior half of the head consisting of longitudinal carinulae, with the posterior half smooth and shiny; and pronotal humerus in dorsal-oblique view rounded. Similar to onyx, but in the major, citrina has a more curved propodeal spine, far less carinulation on the dorsal head surface, and longer scapes, among other differences.
