, but they and related genera are now considered sufficiently distinctive to be separated from that group as the bush-shrike family Malaconotidae. This is an African group of species which are found in scrub or open woodland. They are similar in habits to shrikes, hunting insects and other small prey from a perch on a bush. Although similar in build to the shrikes, these tend to be either colourful species or largely black. Some species are also quite secretive.

Taxonomy and systematics

The genus ''Laniarius'' was introduced by the French ornithologist

Louis Pierre Vieillot Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected ...

type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ...

. The closest relatives of the genus appear to be the genus '' Chlorophoneus''. Previously, members of the genus ''Laniarius'' had been classified on the basis of plumage. However, a 2008 molecular study found that the species had developed different colours and patterns in plumage independently and similar-coloured species were often unrelated. The authors hypothesized that the ancestor of the genus may have been dark-coloured. There are 22 recognised

species A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), ...

: Formerly, some authorities also considered the following species (or subspecies) as species within the genus ''Laniarius'': * Rufous whistler (as ''Laniarius rubrigaster'')
