Description
|
|
Total length of workers around 1.5 mm. Clypeus broad, not fringed with spatulate hairs; anterior margin projecting. Promesonotum not raised.
|
Remarks
|
|
This species is similar to Pyramica benten, but distinguished by its pilosity: the hairs of P. leptothrix are simple, longer and more dense than in P. benten, and those on the head and mesosoma, in particular, are erect. P. leptothrix is found on the floor of broadleaf forests. It was originally described from Funkiko, Taiwan. It corresponds to "Weberistruma sp." of Onoyama (1976) and "Smithistruma sp. 5" of the Myrmecological Society of Japan Editorial Committee (1988).
