Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
DIAGNOSIS Major: virtually identical with Pheidole subarmata major except for its much smaller size (HW about 0.8 mm versus more than 0.9 mm in subarmata) and strikingly different color (see below). Stefan Cover, who has examined this species and subarmata in detail, reports that the head of the triplex major is also slightly narrower.
Minor: virtually identical with Pheidole subarmata minor except for its strikingly different color (see below). Another possible difference is habitat: the triplex types were collected in mature mountain rainforest, while subarmata prefers open, even disturbed habitats.
MEASUREMENTS (mm) Holotype major: HW 0.80, HL 1.06, SL 0.44, EL 0.12, PW 0.46. Paratype minor: HW 0.42, HL 0.46, SL 0.42, EL 0.09, PW 0.28.
COLOR Major: strongly tricolorous, with head and mandibles uniformly medium brown; mesosoma, waist, and appendages yellow; and gaster light brown.
Minor: concolorous clear light yellow.
