Description
Similar to Pheidole micridris but distinguished from it and other Pheidole species as follows.
Major: head in full-face view quadrate, with Head Width equaling Head Length; eyes set well forward on head; pilosity sparse, especially so on mesosomal dorsum, where it comprises widely and evenly spaced pairs of setae; mesonotal convexity low but well developed in side view; propodeal spines as long as half the propodeal basal face and directed backward; postpetiole oval from above; carinulae limited to eye level on head and anterior to it; all of head, mesosoma, and petiole foveolate.
Minor: eye set far forward on head; posterior half of ventral head profile weakly concave; pilosity sparse, and on mesosomal dorsum comprising widely and evenly spaced pairs of setae; all of head, mesosoma, and petiole foveolate.
MEASUREMENTS (mm) Holotype major: HW 0.92, HL 0.92, SL 0.58, EL 0.12, PW 0.42. Paratype minor (Tinlandia, Ecuador): HW 0.40, HL 0.44, SL 0.42, EL 0.06, PW 0.24.
COLOR Major: body dark brown, mandibles medium brown, other appendages brownish yellow. Minor: body yellowish brown, appendages dark yellow.

Type Material
Holotype, major: 20–30 km east-northeast of Alluriquin on Chiriboga Road, Pichincha, Ecuador, 1400–1800 m. Paratype, minor: Tinlandia, 16 km southeast of Santo Domingo de Los Colorados, Pichincha, Ecuador, 520 m. Museum of Comparative Zoology
Etymology
L geminata, pair, twinned, referring to the paired mesosomal setae.
