The worker (minor) of this Pheidole species at 1.2 mm makes it just 0.2 mm longer than a typical Oligomyrmex worker. The queen is very dark brown to almost black in color. The majority of Pheidole species are monogynous but there are quite a number that are polygnous. Most Pheidole species are also dimorphic but there are some exceptions.
Size comparison. Center is an 0.8 mm Oligomyrmex worker, top a very common small Pheidole species sp1, bottom a typical size Pheidole worker at 2.9 mm and left Pheidole sp7 worker at 1.2 mm.
The ant in the center is an Oligomyrmex minor worker, one of the tiniest of ant at 0.8 mm. Top - the most common small Pheidole species which is found all over Malaysia and S'pore is 1.8 mm. There are several other similar size species but most are larger. Bottom, this is the 'typical' size Pheidole worker 2.9 mm. It is around the size of the worker of Pheidologeton diversus. The one on the left is the currently discussed species at 1.2 mm. I had to 'freeze' these specimens in order to photograph them together. They all soon recovered and went their separate ways. But you can't do this with termites.
