Phylogeny
Varela-Hernández & Riquelme (2024), Fig. 3. The phylogenetic status of Pheidole praehistorica among fossil and extant congeners inferred from the list of characters (Supp. file 1: Table S1) and the data matrix (Supp. file 1: Table S2), shows the twenty-eight morphological characters to construct the most parsimonious tree. The numbers above the white and black dots represent morphological characters, and the numbers below represent the character encoding. Black dots represent synapomorphies, and white dots represent homoplasies. † represents fossil species from Dominican and Mexican amber. Consistency index = 0.52; retention index = 0.65.

Description
DIAGNOSIS A member of the “bicarinata complex” of the larger pilifera group, comprising Pheidole agricola, Pheidole aurea, Pheidole barbata, Pheidole bicarinata, Pheidole centeotl, Pheidole cerebrosior, Pheidole defecta, Pheidole gilvescens, Pheidole macclendoni, Pheidole macrops, Pheidole marcidula, Pheidole paiute, Pheidole pinealis, Pheidole xerophila, Pheidole yaqui and Pheidole yucatana, which complex is characterized by the large to very large, forward-set eyes in both castes; and, in the major, the occipital lobes lacking any sculpturing (except in aurea); the posterior half of the head capsule almost entirely smooth and shiny; and the postpetiolar node seen from above oval, elliptical, or laterally subangular (cornulate in cerebrosior).
P. yucatana is distinguished by the following combination of traits.
Major: in side view, promesonotal juncture subangulate; propodeal spines reduced to right angles; occiput sprinkled with sparse but coarse foveae; faint carinulae extend from behind eye to occipital corners; postpetiolar node from above laterally subangulate.
Minor: in side view propodeal spines reduced to right angles.
MEASUREMENTS (mm) Holotype major: HW 1.04, HL 1.20, SL 0.58, EL 0.10, PW 0.48.
Paratype minor: HW 0.52, HL 0.60, SL 0.54, EL 0.14, PW 0.32.
COLOR Major: body medium reddish brown, appendages light reddish brown.
Minor: body light plain brown, tarsi and tibiae yellow, rest of appendages brownish yellow.
Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
Type Material
MEXICO: 11 km south of Progreso, col. E. O. Wilson. Museum of Comparative Zoology
Etymology
L yucatana, from the Mexican region of the type locality.
