Taxonomic History (provided by Barry Bolton, 2017)

Pheidole albipes Wilson, 2003A: 367, figs. (s.w.) MEXICO. AntCat AntWiki HOL

Distribution:


Neotropical Region: Alta Verapaz, Chiapas, Guatemala, Honduras, Izabal, Petén, Veracruz

Comments:

J. Longino, 25 Apr 2014: Very similar to P. orbica in the Antilles. Pheidole albipes and P. ceibana are very similar morphologically. They appear to be a parapatric species pair across the Motagua fault. DNA barcoding supports the split. Pheidole albipes minor workers have brown coxae, contrasting with the ivory femur. Pheidole ceibana has lighter colored coxae that do not contrast strongly with the femora.

Pheidole albipesHNS new species

Types Mus. Comp. Zool. Harvard.

Etymology L albipesHNS, white-footed.

diagnosis A small, strikingly colored species of the flavensHNS group, similar in various traits to alticolaHNS, chalcaHNS, ebeninaHNS, euryscopaHNS, hedlundorumHNS, lustrataHNS, monteverdensisHNS, palenquensisHNS, and serviliaHNS, differing as follows.

Major: reddish brown with strongly contrasting pale yellow tibiae and tarsi, and head bicolorous; region between eye and occipital border irregularly rugoreticulate, occipital margins and center of clypeus smooth and shiny, and rest of dorsal surface of head carinulate; almost all of mesosoma smooth and shiny; humerus subangulate in dorsal-oblique view; postpetiole diamond-shaped from above.

Minor: almost all of head and body smooth and shiny; occiput broad and strongly concave; humerus subdenticulate in dorsal-oblique view.

Measurements (mm) Holotype major: HW 0.60, HL 0.64, SL 0.38, EL 0.10, PW 0.34. Paratype minor: HW 0.38, HL 0.40, SL 0.36, EL 0.06, PW 0.24.

Color Major: body, coxae, and femora medium reddish brown; head anterior to eyes yellow; antennae, tibiae, and tarsi pale yellow. Minor: head and body medium brown; coxae and femora light brown; antennae, tibiae, and tarsi very pale yellow, almost white.

Range Southern Mexico: known from several lowland forested localities in Veracruz, and from forest 7 km south of Valle Nacional, Oaxaca, at 450 m.

biology At the type locality, in degraded lowland forest, I found two colonies nesting in small rotting tree branches in the ground leaf litter, and another colony under the bark of a large rotten log.

Figure Upper: holotype, major. Lower: paratype, minor. MEXICO: Pueblo Nuevo, near Tetzonapa, Veracruz (E. O. Wilson). Scale bars = 1 mm.
