What is "hyliidae"

Not to be confused with Hylidae, a family of amphibians.

Hyliidae is a proposed family of passeriform birds which would include the green hylia (Hylia prasina) and the tit hylia (Pholidornis rushiae). Physiological similarities and recent mitochondrial DNA evidence strongly support the creation of this family. Currently the tit hylia is usually placed in Cettiidae (typical bush warblers), while the placement of the green hylia is uncertain but most often also assigned to Cettiidae.

Hylias are small, insectivorous songbirds found in tropical Africa. They frequent the understory of wet tropical forests.
