Pheidole hoplitica new species

Types Mus. Comp. Zool. Harvard.

etymology Gr hoplitica , referring to the hoplite, a heavily armed soldier of ancient Greece.

diagnosis A member of the " pilifera complex" of the larger pilifera group, comprising calens , californica , carrolli , cavigenis , clementensis , creightoni , hoplitica , littoralis , micula , pilifera , rugulosa , senex , soritis , tepicana , and torosa , which complex is characterized by the following traits. Major: dorsal head surface extensively sculptured; occipital lobes horizontally rugulose (or, in carrolli smooth, in littoralis foveate, and in micula and soritis carinulate); postpetiole from above diamond-shaped, trapezoidal, or spinose. Minor: eye medium-sized to large.

P. hoplitica is distinguished within the complex, including cavigenis , which it most resembles, by the following combination of traits. Major: posterior dorsal profde of head markedly concave; occiput partly rugoreticulate; carinulae that originate from around frontal triangle turn outward near the center of the head toward the occipital corners; promesonotum strongly convex, almost semicircular in profde; postpetiolar node in side view wide and broadly rounded, not narrow and abruptly rounded.

Minor: head and sides of pronotum smooth and shining, not densely sculptured and opaque; some of the hairs of the promesonotal dorsal surface clavate.
