Description
|
|
Total length of workers around 1.5 mm. Body color yellowish brown. Head generally somewhat elongate. Clypeus distinctly longer than broad, anterior margin projecting, without fringing spatulate hairs. Eyes small. Promesonotum not raised. Body hairs abundant, those on head and mesosoma long and flagellate.

Remarks
|
|
The species is similar to the Smithistruma species S. japonica, S. leptothrix and S. benten, but easily distinguished from them by the smaller eyes, elongate head, and distinctive pilosity. It is very rare and is found on the floor of broadleaf forest, nesting in the soil. Pyramica masukoi corresponds to S. sp. 7 of the Myrmecological Society of Japan Editorial Committee (1992).
