Pheidole glyphoderma   HNS new species

Types Mus. Comp. Zool. Harvard.

Etymology Gr glyphoderma   HNS , engraved skin, referring to the elaborate sculpturing of the major.

diagnosis A distinctive member of the tristis   HNS group, characterized by the following traits.

Major: in side view, frontal lobe projects forward to form a conspicuous triangle; parallel transverse carinulae encircle the posterior half of the dorsal surface of the head, curving downward along the genae to reach the anterior margin of the head capsule; each frontal lobe gives rise to parallel carinulae which curve outward on the posterior half of the head and reach the occipital lobes; pronotum and mesonotum (but not the mesopleuron or propodeum) covered by carinulae. Minor: occiput broad, shallowly concave, and lacking nuchal collar; pronotum and mesothorax foveolate and opaque but lacking carinulae.

Close to arietans   HNS , also of Costa Rica, but differing in many features of body form and sculpturing, as illustrated.
