A New Species Of Mexican Tinotus From The Refuse Piles Of Atta Ants, Including An Annotated World Catalog Of Tinotus (Coleoptera: Staphylinidae: Aleocharinae: Aleocharini)

Tinotus refusus, new species, is described based on specimens collected from refuse piles of Atta ants from San Luis Potosi, Mexico. This is the second recorded instance of Tinotus collected from Atta refuse piles and likely represents a species specific to this habitat. An annotated world catalog of Tinotus is also presented with lectotype designations for T. binarius Casey, T. brunneus Casey, T. carnivorus (Cameron), T. castaneus Cameron, T. caviceps Casey, T. cavicollis Sharp, T. coelebs Casey, T. densissimus Bernhauer, T. densiventris Casey, T. flavescens Sharp, T. fusinus Casey, T. imbricatus Casey, T. indicus Cameron, T. kashmiricus Cameron, T. pallidus Casey, T. paratus Casey, T. parvicornis Casey, T. pectinellus Casey, T. rufipennis Cameron, T. texanus Casey, and T. trisectus Casey.

Tinotus is transferred from the Hoplandriini to the Aleocharini based on numerous shared characters that likely represent synapomorphies for the Aleocharini.
