Pentastruma sauteri Forel, 1912a, Pyramica sauteri (Forel): Bolton, 1999,

Total length of workers around 2 mm. Body color yellowish brown. Very similar to Pyramica canina but with the following differences: smaller size; shorter mandibles, which have the teeth on their masticatory margins almost even in size; anterior corners of clypeus more rounded and anterior clypeus margin more deeply concave.

This species was first described from Pilam, Taiwan. In the original description Forel counted 5 antennal segments are in fact 6, as demonstrated by Brown & Boisvert (1979). The first Japanese record of P. sauteri was from Mt. Yonaha-dake, Okinawa, by Terayama (1985). P. sauteri is also present in the Ishigaki Islands (Ogata, unpublished). A rare species found on the floor of broadleaf forests.
