Nylanderia
''Nylanderia'' is a large genus of ants in the subfamily Formicinae. The genus has a nearly cosmopolitan distribution with species inhabiting a wide array of habitats in almost all geographic regions. ''Nylanderia'', currently containing over 110 species, is an ecologically important genus, with some species reported as being invasive. The ants are small to medium in size and range in color from pale yellow to black.
==Taxonomy==
The genus was first described as a subgenus of ''Prenolepis'' by Emery (1906), a status he revised a couple of years later when he placed it as subgenus of ''Paratrechina'' (Emery, 1925).〔〔 Wheeler (1936) raised ''Nylanderia'' to genus, where it remained until Brown (1973) provisionally placed it as a junior synonym of ''Paratrechina'', a status which was later confirmed by Trager (1984).〔〔〔 ''Nylanderia'' was finally revived from synonymy and restored at the rank of genus by LaPolla, Brady & Shattuck (2010).〔
Until 2010, most ''Nylanderia'' species were placed in the genus ''Paratrechina'', but molecular phylogenic studies and reassessment of morphological characters prompted resurrection of ''Nylanderia'' as a valid genus.〔〔 The genus currently comprises over 108 extant species and two fossil species:〔 ''N. pygmaea'' from Eocene age Baltic amber and ''N. vetula'' from Miocene age Dominican amber.〔〔
