Type Material

BRAZIL: Mato Grosso. Museo Civico di Storia Naturale, Genoa - as reported in Wilson (2003)

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.


From Wilson (2003): DIAGNOSIS A medium-sized reddish brown member of the tristis group whose major has a large, laterally subangulate postpetiolar node, moderately protuberant and rounded subpostpetiolar process, very prominent lobose humerus, swollen hind femora, and weak transverse carinulae covering the entire promesonotum.

Minor: dorsal pilosity consists of sparse, short hairs, some of which are clavate or spatulate; occiput narrow, with nuchal collar; propodeal spine erect. Similar to Pheidole alpinensis, Pheidole exarata, Pheidole excubitor, Pheidole grandinodus, Pheidole grantae {=Pheidole exarata), Pheidole obrima, Pheidole rogeri, Pheidole stulta, Pheidole tristis and Pheidole zoster, differing in many details of body form, sculpturing, and pilosity, as illustrated, and in color.

MEASUREMENTS (mm) Lectotype major: HW 1.56, HL 1.80, SL 0.86, EL 0.20, PW 0.80. Paralectotype minor: HW 0.66, HL 0.72, SL 0.74, EL 0.12, PW 0.46.

COLOR Major: head and appendages rich medium reddish brown, rest of body dark reddish brown.

Minor: body very dark reddish brown, appendages a contrasting light reddish brown.
