From Wilson (2003): In Costa Rica Longino (1997) found gauthieri in mature wet forest, nesting in dead wood in the low arboreal zone and foraging in the leaf litter and at extrafloral nectaries. A winged queen was present in a nest on Barro Colorado Island, Panama, 27 June (W. M. Wheeler).

Description
From Wilson (2003): DIAGNOSIS Similar to Pheidole antillana, Pheidole coveri, Pheidole fullerae, Pheidole hetschkoi, Pheidole heyeri and Pheidole napoensis in various traits but easily distinguished as follows.
Major: propodeal spines as long as basal face of propodeum; occiput smooth and shiny; smaller patch of rugoreticulum present laterad to each antennal fossa; loose rugoreticulum present on anterior half of pronotal dorsum but absent on posterior half; postpetiole spinose.
Minor: occiput, sides of head, and entire dorsum of mesosoma rugoreticulate, and almost all of remainder of head and mesosoma variously rugulose or carinulate; propodeal spines as long as basal face of propodeum; occiput narrowed but lacking a nuchal collar.
MEASUREMENTS (mm) Major (Panama): HW 2.04, HL 2.12, SL 0.86, EL 0.20, PW 0.94. Lectotype minor: HW 0.80, HL 0.81, SL 0.86, EL 0.16, PW 0.54.
COLOR Major: concolorous light reddish brown.
Minor: head and meso soma light reddish yellow; waist, gaster, and appendages clear dark yellow.
Figure. Upper: syntype, major of synonymous gauthieri var. oxymora (Panama). Lower: lectotype, minor (road from Dibulla to San Antonio, Guajira, Colombia). Scale bars = 1 mm.
Type Material
Panama. Musee d'Histoire Naturelle Genève - as reported in Wilson (2003)
Etymology
Named after A. and C. Gauthier of Colombia, who assisted Forel in his itinerary. (Wilson 2003)
