Fernández (2011) - With the general habitus of ''[[Pheidole fiorii]]'' in the [[Key to Pheidole fallax group|''Pheidole fallax'' group]]. Minor worker: head smooth and shining versus foveolated and opaque / subopaque (''fiorii''); side of propodeum smooth and shining versus with some foveolated (''fiorii''); metanotal groove deeply impressed ''versus'' shallowly impressed (''fiorii''). Major worker: dorsal surface of mandible flat to weakly convex versus with broad concavity covering basal half of dorsal surface (''[[Pheidole fossimandibula]]''); clypeus with large setal tufts in the form of pompons ''versus'' smooth and flat (''[[Pheidole vestita]]'') or with weak gibbosities (''fossimandibula''), setae sparse to abundant but not in form of pompons (''fossimandibula'', ''vestita''); face between frontal carinae with large hemispherical concavity versus simple, typically convex (''fossimandibula'', ''vestita'').

The smooth and shining head, well developed occipital carinae, and long, downturned propodeal spines differentiate the minor worker of this species of any other in the genus and ''fallax'' group. ''P. fiorii'' is near to this species, but with clear differences (see above), including setae (shorter in ''iceni'') and color (light brown in ''iceni'') and smooth and shining pronotum, sides of petiole (variably foveolated in ''fiorii'').

Paratype Specimen Label

The type workers were collected during the day in lowland rainforest.

Identification

Fernández (2011) - With the general habitus of Pheidole fiorii in the Pheidole fallax group. Minor worker: head smooth and shining versus foveolated and opaque / subopaque (fiorii); side of propodeum smooth and shining versus with some foveolated (fiorii); metanotal groove deeply impressed versus shallowly impressed (fiorii). Major worker: dorsal surface of mandible flat to weakly convex versus with broad concavity covering basal half of dorsal surface (Pheidole fossimandibula); clypeus with large setal tufts in the form of pompons versus smooth and flat (Pheidole vestita) or with weak gibbosities (fossimandibula), setae sparse to abundant but not in form of pompons (fossimandibula, vestita); face between frontal carinae with large hemispherical concavity versus simple, typically convex (fossimandibula, vestita).

The smooth and shining head, well developed occipital carinae, and long, downturned propodeal spines differentiate the minor worker of this species of any other in the genus and fallax group. P. fiorii is near to this species, but with clear differences (see above), including setae (shorter in iceni) and color (light brown in iceni) and smooth and shining pronotum, sides of petiole (variably foveolated in fiorii).

Distribution
