Nylanderia flavipes

(Smith, 1874)

Yellow-footed Ant

Nylanderia flavipes is a small in the Formicinae, to Asia and to the Nearctic region including the United States. It was previously classified under the Paratrechina before taxonomic revision. The species serves as a documented for the Gollumiella buffingtoni, with showing unusual and active assistance toward the parasitoid's development. It is one of at least five introduced Nylanderia species established in the Nearctic region.

Identification

Identification to level typically requires examination of male specimens, as of Nylanderia flavipes are morphologically similar to other Nylanderia species. The species was historically classified as Paratrechina flavipes; taxonomic revision moved it to Nylanderia. In the Nearctic region, it is distinguished from Nylanderia species by its status. Molecular or detailed morphological analysis may be necessary for definitive identification where workers of multiple introduced and native species co-occur.

Appearance

Small with yellowish legs, consistent with the specific epithet 'flavipes' meaning -footed. possess the general typical of Nylanderia: small size, hairs on body, and relatively long . Detailed morphological descriptions require examination of or specialized taxonomic literature.

Habitat

Forest edge environments in range, with nests located under stones. In range, specific preferences are less documented but likely include disturbed and natural habitats suitable for small Formicine .

Distribution

to Asia (Japan, and likely broader Asian distribution based on historical records as Paratrechina flavipes). to the Nearctic region, including the conterminous United States. Records from Germany, Spain, United Arab Emirates, and Iran suggest additional introduced or broader native range.

Host Associations

Gollumiella buffingtoni - ; attach to larvae and enter their bodies; naked are tolerated and transported by N. flavipes

Behavior

exhibit phoretic transport of on their . Workers tolerate and actively transport naked of the parasitoid Gollumiella buffingtoni within the nest. Workers assist with parasitoid by removing pupal exuvium. Newly emerged parasitoid remain motionless before exiting the nest, suggesting behavioral that may reduce aggression from .

Ecological Role

Documented for , contributing to understanding of ant-parasitoid evolutionary and chemical . As an in the Nearctic, its ecological impacts on ant are not well documented.

Human Relevance

One of several Nylanderia in the Nearctic region; not noted as a significant pest or species in available sources. Taxonomic importance due to historical confusion with related species.

Taxonomic History

Previously classified as Paratrechina flavipes (Smith, 1874); transferred to Nylanderia following taxonomic revision of the . References to Paratrechina flavipes in older literature (e.g., Ichinose 1986, 1987) refer to this .

Parasitoid Relationship

The association with Gollumiella buffingtoni represents a well-documented case of - integration. The high of N. flavipes toward the parasitoid, including active assistance during , suggests chemical or other mechanisms of social integration. This system has been studied in Central Japan.
