I'm not good with Utricularia either, so I can't help with identification...basically, you'll want to keep the plant in an undrained container in a peat based mix with the water level around the soil line (it can fluctuate, which will actually mimic the plant's natural habitat). As usual, full sun will be appreciated. During the growing season, keeping it with your U. sandersonii might be fine. During winter, these plants are accustomed to dormancy very similar to the dormancy that you would give Sarracenia and Dionaea. My North American Utricularia seem to freeze solid every year, and they always bounce back. They can be grown without dormancy, but they'll be less likely to flower without their seasonal cues (except for annoying U. subulata which always produces those unsightly cleistogamous flowers).
