The Australasian wrens are a family, Maluridae, of small, insectivorous passerine birds endemic to Australia and New Guinea. While commonly known as wrens, they are unrelated to the true wrens of the Northern Hemisphere. The family comprises 29 species (including fifteen fairywrens, three emu-wrens, and eleven grasswrens) in six genera.
As with many other Australian creatures, and perhaps more than most, the species making up this family were comprehensively misunderstood by early researchers. They were variously classified as Old World flycatchers, Old World warblers, and Old World babblers. In the late 1960s morphological studies began to suggest that the Australo-Papuan fairywrens, the grasswrens, emu-wrens and two monotypic wren-like genera from New Guinea were related and, following Charles Sibley's pioneering work on egg-white proteins in the mid-1970s, Australian researchers adopted the family name Maluridae in 1975.
With further morphological work and the great strides made in DNA analysis towards the end of the 20th century, their position became clear: the Maluridae are one of the many families to have emerged from the great corvid radiation in Australasia. Their closest relatives are the honeyeaters (Meliphagidae), and the pardalotes (Pardalotidae). Their obvious similarity to the wrens of Europe and America is not genetic, but simply the consequence of convergent evolution between more-or-less unrelated species that share the same ecological niche.
A 2011 analysis of mitochondrial and nuclear DNA found the broad-billed fairywren and Campbell's fairywren, both formerly lumped together in the genus Malurus, to lie in a clade with the two other monospecific New Guinea genera and as such, they were later re-classifed as separate species within the genus Chenorhamphus.
