Geographic range. Guatemala . Diagnosis. Minor : face foveolate, overlain with faint reticulate rugulae; promesonotum box-like, promesonotal groove weakly impressed; entire mesosoma foveolate, dorsal pronotum overlain with reticulate rugulae; propodeal spines about one half length of posterior face of propodeum; gaster smooth and shining; mesosomal dorsum and gaster with abundant, flexuous setae; tibiae with abundant, short, suberect setae (not differentiated into appressed pubescence and standing setae); color dark red brown. Major : inner hypostomal teeth distinct, closely-spaced; scape base terete; face entirely foveolate, overlain throughout with weak reticulate rugulae; propodeal spines about one third length of posterior face of propodeum; gastral dorsum smooth and shining; sides of head with abundant erect setae, other pilosity similar to minor worker.

This species is known from one locality, in mature cloud forest on the slopes of Volcán Atitlán, between 1500-2100 m elevation. Workers occur at ground baits and in Winkler samples of sifted litter and rotten wood. A dealate queen was collected in a Winkler sample. Comments . Pheidole atitlana is part of a clade that contains P. rectitrudis , P. beloceps , and others ( Economo et al. 2019 , as JTL195). Etymology : From the type locality.
