Language:	Japanese

Nests are found under stones or rotting wood, or in forest leaf-litter. They include only a few tens of workers. When nests are breached the workers disperse rapidly, so it is difficult to census colonies. Reproductive females are ergatoid. Males are winged and typically ponerine in habitus, but with pectinate tarsal claws. (Japanese Ant Image Database)
