Seevers, 1958
Vatesini is a tribe of () established by Seevers in 1958, classified within the Tachyporinae. The tribe comprises ten extant and extinct , including Cilea, Coproporus, Vatesus, and the fossil genus †Procileoporus. Members are small to -sized with the characteristic of Staphylinidae.

Identification
Vatesini can be distinguished from other Tachyporinae tribes by combinations of characters including antennal structure, tarsal formula, and male . The Vatesus is notably associated with (Ecitoninae), exhibiting behavioral and morphological for . Cileoporus and Tachinoporus share reduced and compact body forms. Accurate identification to genus level requires examination of structure and detailed mouthpart morphology.

Distribution
The tribe has a distribution with occurring across multiple continents. Cilea and Coproporus are widespread in the Palearctic and Nearctic regions. Vatesus are found in the Neotropics where they inhabit colonies. Termitoplus occurs in association with nests. The fossil genus †Procileoporus is known from Eocene Baltic amber, indicating ancient presence in Europe.
Host Associations
- Ecitoninae - myrmecophileVatesus are obligate associates of colonies
- Termitidae - Termitoplus inhabit nests
Behavior
Vatesus exhibit obligate , living within colonies of (Eciton) where they likely feed on or regurgitations. These possess that secrete substances attractive to ants, facilitating integration into colonies. Termitoplus species are termitophilous, inhabiting nests with poorly understood ecological roles. Other such as Coproporus and Cilea are generally found in decaying matter including and compost.
Ecological Role
Members of Vatesini function as commensals or in colonies. Vatesus are considered obligate myrmecophiles with potential kleptoparasitic or predatory roles on . Coproporus and related contribute to in decomposing substrates. The ecological function of Termitoplus within colonies remains insufficiently documented.

Fossil record
The extinct †Procileoporus, described from Eocene Baltic amber by Yamamoto in 2016, represents the only described fossil member of the tribe and provides age constraints for Vatesini diversification.
Taxonomic history
The tribe was established by Seevers in 1958, with subsequent revisions by Campbell (1994) adding Cileoporus and Yamamoto (2016) describing the fossil . Generic boundaries remain actively studied.
