Nomenclature
The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.
- alpinensis. Pheidole emeryi var. alpinensis Forel, 1912f: 231 (s.w.q.) BRAZIL. Subspecies of tristis: Bolton, 1995b: 316. Raised to species: Wilson, 2003: 650.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Description
From Wilson (2003): DIAGNOSIS A large, reddish brown (major) or reddish yellow (minor) member of the tristis group with very prominent subangulate humeri, large subangulate postpetiolar node, small subpetiolar process, and weakly shagreened first gastral tergite, in both major and minor.
Close to Pheidole tristis, and less similar to Pheidole exarata, Pheidole excubitor, Pheidole germaini, Pheidole obrima, Pheidole rogeri, Pheidole stulta and Pheidole zoster, differing in many details of body form, sculpturing, and pilosity, as illustrated, as well as in color. .
MEASUREMENTS (mrn) Lectotype major: HW 1.74, HL 2.00, SL 0.84, EL 0.20, PW 0.86. Paralectotype minor: HW 0.76, HL 0.84, SL 0.80, EL 0.14, PW 0.48.
COLOR Major: concolorous reddish brown. Minor: concolorous reddish yellow.
Figure. Upper: lectotype, major. Lower: paralectotype minor. Scale bars = 1 mm.
Type Material
BRAZIL: Colonia Alpina, Teresiopolis, Rio de Janeiro. Musee d'Histoire Naturelle Genève - as reported in Wilson (2003)
