Small ants (1-3 mm) are reddish-brown in color with characteristic large-headed soldiers. Anterior margin of pronotum with keeled, humeral tubercles developed. There are spikes on the propodeum. The antennae of workers and females are 12-segmented (13 in males) with a 3-segmented mace. The width of the head of large workers (HW) is 1.16 mm (the length of the head is 1.18 mm). The width of the head of small workers is 0.56 mm (the length of the head is 0.58 mm). The scape of the antennae of the soldiers is short, 2 times shorter than the length of the head. The whole body of small workers is opaque; the head of a soldier is reticulate. The stalk between the breast and the abdomen consists of two segments: the petiolus and postpetiolus (the latter is clearly separated from the abdomen) [1] .
A case is known in Argentina in the nest of P. obtusopilosa of ants Oxyepoecus bruchi [2] .
The species was first described in 1887 by Austrian worldmecologist Gustav Mayr for workers and soldiers and named obtusopilosa by the presence of coarse bristles on the body [3] . Males were first described in 1917, and females in 1926 by the Italian worldmecologist Felix Sanchi (F. Santschi) [4] [5] . Pheidole obtusopilosa belongs to the species group Pheidole flavens Group and is similar to the species Pheidole heterothrix [1] .
