Description
From Wilson (2003): A medium-sized member of the diligens group, and inhabitant of high montane forests, similar to Pheidole alfaroi, Pheidole laelaps, Pheidole riveti, Pheidole seligmanni and Pheidole tepuicola, somewhat less so to Pheidole vafra and Pheidole strigosa, and distinguished from these and other Pheidole 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.
Figure. Upper: lectotype, major. Lower: paralectotype, minor. Scale bars = 1 mm.
Type Material
COSTA RICA: Las Palmas, near Bajo la Hondura, Braulio Carrillo National Park. Musee d'Histoire Naturelle Genève - as reported in Wilson (2003)
Etymology
No allusion given; presumably after Diana, the Roman goddess of nature, fertility and conception, and the Moon. (Wilson 2003)
