Description

DIAGNOSIS From Wilson (2003): Similar in various respects but not close to Pheidole bellatrix, Pheidole bison, Pheidole napoensis, Pheidole pullula, and members of the gertrudae group.

Major: in side view the mesonotum descends in a vertical face to the metanotum, which may bear a very small convexity; head anterior to posterior margin of eye partly carinulate and rest of body smooth and shiny; humerus in dorsal-oblique view rounded or subangulate; propodeal spines equilaterally triangular.

Minor: head and body almost completely smooth and shiny; promesonotal profile almost perfectly semicircular; propodeal spines reduced to denticles; postpetiolar node from side low, and from above oval.

MEASUREMENTS (mm) Lectotype major: HW 1.52, HL 1.56, SL 0.90, EL 0.22, PW 0.70. Paralectotype minor: HW 0.66, HL 0.74, SL 0.78, EL 0.12, PW 0.44.

COLOR Major and minor: concolorous brownish yellow.

Type Material

New Grenada,” Greater Colombia. Naturhistorisches Museum Wien, Vienna - as reported in Wilson (2003)

Etymology

L incisa, cut into, probably alluding to the sharp descent of the mesonotum. (Wilson 2003)
