This bacterial species isn't newly discovered but it's been known by other names. It's been in the genus Flavobacterium and in Chryseobacterium previously. It's been associated with soft tissue infections, even among immunocompetent individuals (but hey, all kinds of species can become opportunistic under the right conditions).
Here's that mosquito paper:
