Pheidole gulo

Pheidole gulo Wilson, 2003: 295 . Holotype major worker: Nicaragua, Rio Kukra (Ivette Perfecto) [MCZC, examined]. Pheidole JTL197: morphospecies code previously used on AntWeb.

In most populations of P. gulo, the minor worker has a fully foveolate face and mesosoma. Specimens from Los Tuxtlas Biological Station in Veracruz, Mexico, and from the slopes of Volcán Atitlán in Guatemala have the face and parts of the pronotum smooth and shining. There is no known site of sympatry of the two forms. The morphospecies code JTL197 was used for the shiny form of P. gulo . In Economo et al. (2019) a shiny specimen from Volcán Atitlán is genetically close to a foveolate specimen from Nicaragua. Pending further evidence, I treat this as one species with geographic variation.
