Rhinotermitidae in the context of Rhinotermitinae

Rhinotermitidae sensu novo are a family of Neoisopteran termites formerly represented by taxa known as Subterranean termites (Heterotermitidae, Psammotermitidae, etc...) but is now only represented by genera within the historical subfamily Rhinotermitinae. The soldiers of Rhinotermitidae notably possess a labral brush, a highly modified projection of the labrum which channels the fontanellar fluid onto a hairy tip, which is used to smear threats. The Rhinotermitidae have a wide distribution, being found from the Neotropics to the Indomalayan, Afrotropical, Australasian, and Palearctic (Sino-Japanese) realms.
