Biology:Uwari
Uwari is a monotypic genus of Camponotine ant distributed in East Asia, mainly Japan. It was established by Ward et al. 2025, its species being previously classified under Camponotus subgenus Myrmentoma.
Taxonomy
The genus was described in 2025 by Ward et al.[1] The type species is Uwari keihitoi, originally named Camponotus keihitoi by Auguste Forel in 1913. The generic name is derived from the Japanese words uwa ("wow") and ari ("ant").[1]
Distribution
The genus is distributed in East Asia. Uwari occurs mainly in Japan, with records also from China and Korea. Colonies are arboreal, typically nesting in twigs and dead wood within forest and forest-edge habitats.[2]
Description
Workers show limited size variation and are characterized by mandibles with five teeth, a broadly convex clypeal margin without indentation, and a clypeus that is wider than long and lacks a median carina. The frontal carinae expand posteriorly, and the antennal scapes are relatively short. The mesosoma is somewhat flattened, with a weakly raised metanotum and a rounded junction to the propodeum. The petiole is slender and scale-like, tapering to a point at the top. Standing hairs are sparse, absent from the mesosoma and petiole, and present only in small numbers on the head and gaster. The body is lightly sculptured, shiny, and blackish brown with lighter appendages.[2]
Species
Uwari is a monotypic genus, as defined by Ward et al. 2025. U. teranishii and U. tokyoensis were added to the genus but synonymized under U. keihitoi.
