This species is known from one locality, in mature cloud forest on the slopes of Volcán Atitlán, Guatemala, 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.
Identification
Longino (2019) - 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.
Measurements, minor worker: HW 0.55, HL 0.60, SL 0.55, EL 0.11, WL 0.73, PSL 0.08, PTW 0.10, PPW 0.18, CI 92, SI 99, PSLI 14, PPI 175 (n=5).
Measurements, major worker: HW 1.17, HL 1.24, SL 0.62, EL 0.15, WL 1.00, PSL 0.09, PTW 0.17, PPW 0.42, CI 95, SI 53, PSLI 8, PPI 251 (n=2).
Measurements, queen: HW 1.09, HL 0.93, SL 0.60, EL 0.29, WL 1.54, PSL 0.10, PTW 0.26, PPW 0.61, CI 118, SI 55, PSLI 9, PPI 237 (n=1).
Pheidole atitlana is part of a clade that contains P. rectitrudis, P. beloceps, and others (Economo et al. 2019, as JTL195).
