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 Pheidole morelosana is similar in various traits to Pheidole bilimeki, Pheidole floridana, Pheidole goeldii, Pheidole grex and Pheidole rectispina, distinguished as follows.
Major: dark yellow; occiput broad and deep; pilosity dense and very long, many hairs much longer than Eye Length; humerus subangulate in dorsal-oblique view; propodeal spines long, nearly vertical to propodeal basal face in dorsal-oblique view; promesonotal profile flat in side view; postpetiolar node very low in side view and spinose from above; mesosoma entirely foveolate and opaque.
Minor: eye small, oval; all of head and mesosoma foveolate and opaque; petiolar node broad and rounded at apex; postpetiolar node low; occiput broad, its margin concave.
MEASUREMENTS (mm) Holotype major: HW 0.78, HL 0.88, SL 0.42, EL 0.08, PW 0.44. Paratype minor: HW 0.44, HL 0.50, SL 0.42, EL 0.06, PW 0.28.
COLOR Major: concolorous dark yellow except for antennae and tarsi, which are pale yellow. Minor: concolorous medium yellow except for tarsi, which are pale yellow.
Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
