Taxonomy and systematics
Phylogeny
The genus ''Ploceus'' was introduced by the French naturalist
Georges Cuvier in 1816. The
type species
In 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 species that contains the biological type specime ...
was subsequently designated as the
baya weaver
The baya weaver (''Ploceus philippinus'') is a weaverbird found across the Indian Subcontinent and Southeast Asia. of these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for their hanging ret ...
. The genus name is from
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic p ...
πλοκευς ''plokeus'' meaning "weaver", and is derived from the Greek word πλεκω ''plekō'' "to entwine".
Based on recent
DNA-analysis, the genus ''Ploceus'' is almost certainly
polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of conver ...
. If all species currently included in the genus would remain and the genus would be made monophyletic, it would have to encompass the entire subfamily Ploceinae. The Ploceinae can be divided into two groups. In the first group, the widowbirds and bishops (genus ''
Euplectes'') are sister to a clade in which the genera ''Foudia'' and ''Quelea'' are closest relatives and which further includes the Asiatic species of ''Ploceus'', i.e. ''P. manyar'', ''P. philippinus'', ''P. benghalensis'', ''P. megarhynchus'', (and ''P. hypoxanthus'', although untested). Since
Georges Cuvier picked ''P. philippinus'' as the
type species
In 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 species that contains the biological type specime ...
, these five species would logically remain assigned to the genus ''Ploceus''.
Basic to the second group is a clade consisting of both species so far included in ''Ploceus'' that live on Madagascar, ''P. nelicourvi'' and ''P. sakalava'', and these are morphologically very distinct from the remaining species. These two species could in future be assigned to the genus ''Nelicurvius'' that was erected by
Charles Lucien Bonaparte in 1850, but which was merged with ''Ploceus'' later on. This second group further contains the genera ''
Malimbus
''Malimbus'' is a genus of birds in the family Ploceidae. It was erected by the French ornithologist Louis Jean Pierre Vieillot in 1805.

Anaplectes

'', and all remaining ''Ploceus'' species. As ''Malimbus'' is the earlier name, erected by Vieillot et al. in 1805, the remaining species of ''Ploceus'', as well as ''Anaplectes rubiceps'', could in future be assigned to ''Malimbus''. These changes are largely corroborated by morphological revisions.
Provided that the other genera that have not been proposed to be merged into an extended "''Malimbus''" are monophyletic, the following (incomplete) tree expresses current insights.
Species list
The genus contains 65 species.
