Myrmica williamsi

Nothing is known about the biology of .

Identification
M. williamsi was described from a single holotype worker because this specimen so well differs from any other Myrmica species that have antennal scapes weakly curved at their base and frontal carinae that curve outwards to merge with the rugae which surround antennal sockets. The main distinguishing features are the very short, dentiform but sharp propodeal spines and unusual sculpture of the alitrunk: the promesonotal dorsum is coarsely reticulate and very finely punctated, sides of the pronotum are sinuously rugulose; while the remaining parts of the alitrunk, petiole and postpetiole have no rugae but are densely punctated.
