  • laevifrons. Pheidole laevifrons Mayr, 1887: 598 (s.) BRAZIL. See also: Wilson, 2003: 199.

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


From Wilson (2003): A small, yellow member of the diligens group, distinguished as follows.

Major: cephalic sculpturing limited to the anterior third of the head, level with and anterior to the eyes; moderately abundant pilosity; relatively short propodeal spines. Close to Pheidole peregrina, but major with much shallower occipital cleft in frontal view, thinner petiolar peduncle and node in side view, and more mesad placement of cephalic rugoreticulum.

Minor: thicker propodeal spines and longer scapes. Also similar to Pheidole triconstricta but with much denser pilosity, shallower occipital cleft, and bilobous as opposed to trilobous promesonotal profile in dorsal-oblique view.

See also the less similar Pheidole coffeicola, Pheidole pubiventris, Pheidole seeldrayersi and [[Pheidole variegata.

MEASUREMENTS (mm) Lectotype major: HW 1.08, HL 1.06, SL 0.86, EL 0.20, PW 0.54. Paralectotype minor: HW 0.60, HL 0.70, SL 0.82, EL 0.14, PW 0.36.

COLOR Major and minor: concolorous yellow.
