These ants are native to Japan and Korea. These ants are dimorphic, and the length of the workers is mostly 1.5, the antennae is pretty short. These ants like to steal brood of Solenopsis Molesta and other species by having various tunnels connected to the other species nests, so they can get brood as they please without the other ants noticing as they are polygonous.  know that they like their nests moderately moist, but still a part of it dry. I also know that they will accept brood of any other Solenopsis species in the area, so that can be used as a brood boost. It was hard to find information for this species and this is the most we could get.
