In 1965 Brian published a major paper dealing with the Rhagionidae he collected during his two expeditions to Madagascar (Stuckenberg 1965).
In 1973 Brian helped sort out the heterogeneous muddle of diverse brachyceran flies that at that time represented the Rhagionidae (Stuckenberg 1973).
1 Later Brian provided additional examples of rostrum elongation as a notable adaptation in various families of Diptera, including the Rhagionidae, Tanyderidae, Sciaridae and Ceratopogonidae that are principally associated with the specialised flora of the Cape region of South Africa (Kirk-Spriggs & Stuckenberg 2009: 158-159).

The adults differ from the Rhagionidae
in having the wings more narrowed at the base and in having apical spurs on the front tibiae (Triplehorn et al.
