Pheidole citrina  HNS  new species

Types Mus. Comp. Zool. Harvard.

Etymology L citrina  HNS  , of citron, referring to yellow body color.

Diagnosis A very small, yellow member of the flavens  HNS  group whose major is marked by its strongly curved propodeal spine (as though the tip had "melted" backward); long scapes, which reach the occipital comers; 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  HNS  , but in the major, citrina  HNS  has a more curved propodeal spine, far less carinulation on the dorsal head surface, and longer scapes, among other differences. See also the less similar grex  HNS  and humida  HNS  .
