Pheidole kukrana

In Costa Rica, kukrana is very adaptable, occurring in seasonal dry forest, and mature and secondary lowland rainforest, and nesting opportunistically in small cavities both on the ground and in the canopy; it occasionally builds carton walls (Longino 1997).

Identification
See the description in the nomenclature section.

Distribution
From Wilson (2003): Known from the type locality, from both the Atlantic and Pacific lowlands of Costa Rica (J. T. Longino), and from Venezuela (4 km northeast of Biscucuy, Portuguesa, 670 m; W. L. Brown and J. Lattke).

This taxon was described from Nicaragua.

Dorsal and lateral surfaces of head coated with dense, long, subdecumbent yellowish hairs.

Minor: occiput drawn into neck, with nuchal collar; propodeal spines reduced to denticles; anterior strip of pronotal dorsum foveolate and opaque.
