Taxonomic history

Distribution:

Mexico south to Colombia, Venezuela, Trinidad, Puerto Rico.

Biology:

This species occurs in various habitats, including highly disturbed areas (city parks), seasonal dry forest, mature lowland rainforest, and second growth rainforest. It can occur on the ground or in the canopy. Workers readily recruit to baits, and major workers often recruit along with minor workers. Nests are in small cavities and appear to be somewhat opportunistically inhabited.

Comments:

Although Wilson (2003) illustrated a "Lectotype major worker," no lectotype label was found among the type material of P. susannae at MHNG.

The syntypes of P. susannae and P. obscurior are very similar in all respects but color. The syntypes of P. susannae are yellow; those of P. obscurior are dark brown. The key in Wilson separates the species on relative scape length in the major, with P. obscurior purported to have relatively longer scapes. However, measurements of the types reveal that the lectotype of P. obscurior has a SI that is actually lower than that of syntypes of P. susannae.

Pheidole susannae is a relatively common species found in disturbed habitats throughout the Neotropics. It appears quite uniform in morphology across its range. Most specimens are dark red brown. The types from Guatemala and a few collections from El Salvador and Nicaragua are yellow.
