Description
|
|
Total length of workers around 3.5 - 4 mm. Body color yellowish brown to reddish brown. Mandibles each with 8 teeth, the apical 4 larger than the others. Dorsal outline of clypeus distinctly produced, forming a right-angle in lateral view. Petiolar node thick; subpetiolar process present on anterior portion, forming a small rounded projection; the remaining ventral margin of petiole straight.

Remarks
|
|
This species resembles C. sauteri, but is easily distinguished by the configuration of the clypeus, petiolar node, and subpetiolar process. Cryptopone sp. of Onoyama (1976) and C. sp. 2 in Myrmecological Society of Japan Editorial Committee (1989) correspond to this species. It is distributed on Amami-oshima Island and southwards, and nests in the leaf litter and soil in forests. Relatively common in the Nansei Islands.
