Description
|
|
Total length of workers around 3 - 3.5 mm. Body color reddish brown. Similar to P. itoi, but the frontal carinae are narrower and overhang the antennal insertions more vertically than in P. itoi. Anterodorsal paired projections of petiole prominent; in dorsal view the margination between them dark-colored. Subpetiolar process larger than in P. itoi, with the tip usually acutely pointed (though variable).

Remarks
|
|
This recently named species corresponds to P. sp. 4 of Myrmecological Society of Japan Editonal Committee (1988). Sometimes formerly reported as P. itoi. For example, Sonobe's (1974) figure of "P. itoi" in fact depicts P. morisitai. The distribution overlaps that of P. itoi, but morisitai is more sporadic. Rare.
