Sciadocerini

Sciadocerini is a tribe of ants belonging to the subfamily Formicinae. The tribe currently contains only one described genus, Sciadoceros, with two known species. Sciadoceros is a monotypic genus, meaning it contains only one species, Sciadoceros ishi. This species is found in Japan. The other species in the tribe, Sciadoceros kishimii, was formerly placed in the genus Formica and later moved to Sciadoceros.

The ants in Sciadoceros are small and have a peculiar morphology. They possess a single, large, dorsal eye spot, which gives them their name. This eye spot is a distinctive feature and sets them apart from other ants. The function of this eye spot is not fully understood, but it is hypothesized to be involved in light detection or orientation.

Sciadocerini ants are known to inhabit forest environments. Their nests are typically found in soil or under leaf litter. Information regarding their diet and social structure is limited due to their rarity and elusive nature. Further research is needed to fully understand the biology and ecological role of this interesting ant tribe. The classification of Sciadoceros within Formicinae is based on morphological characteristics, and phylogenetic studies are ongoing to confirm its precise placement within the ant family tree.
