Pheidole diana Forel 1908   HNS c: 51.

Types Mus. Hist. Nat. Geneve.

etymology No allusion given; presumably after Diana, the Roman goddess of nature, fertility and conception, and the Moon.

diagnosis A medium-sized member of the diligens   HNS group, and inhabitant of high montane forests, similar to alfaroi   HNS , laelaps   HNS , riveti   HNS , seligmanni   HNS , and tepuicola   HNS , somewhat less so to laticornis   HNS and strigosa   HNS , and distinguished from these and other Pheidole   HNS species by the following combination of traits.

Major: sculpturing confined to carinulae on margins of frontal lobes, anterior third of the head capsule, and entire surface of the propodeum, with the rest of the body smooth and shiny; propodeal spines reduced to denticles; postpetiole from above diamond-shaped.

Minor: sculpturing confined to circular carinulae of antennal fossae and transverse carinulae of dorsal propodeal surface, with the rest of the body smooth and shiny; propodeal spines absent; basal and declivitous faces of propodeum meet in an obtuse angle; nuchal collar absent.

Measurements (mm) Lectotype major: HW 1.40, HL 1.44, SL 0.90, EL 0.22, PW 0.72. Paralectotype minor: HW 0.66, HL 0.76, SL 0.72, EL 0.12, PW 0.44.

Color Major: appendages and most of body medium reddish yellow; gaster a slightly darker shade of plain light brown. Minor: body concolorous plain light brown; appendages a slightly contrasting lighter shade.

Range Upper elevations of Cordillera Central and Cordillera de Tilaran, Costa Rica, including the Braulio Carrillo National Park, Penas Blancas Valley, and Monteverde (Longino 1997).

biology An arboreal species that nests under epiphyte mats in the canopy of cloud forest and montane wet forest; some colonies are very large (Longino 1997).
