Reinstatement of Eschatoporiini Blaisdell, 1906, a unique tribe of blind cavernicolous Tenebrionidae from California, with a new species from Napa County (Coleoptera, Tenebrionidae, Lagriinae).

The tribe Eschatoporini Blaisdell, 1906 is reinstated, based on molecular and morphological data, and the spelling corrected as Eschatoporiini. The tribe currently includes only the cave-dwelling genus Eschatoporis Blaisdell, 1906 from California, which is associated with underground aquifers. A second species of Eschatoporis is described from a cave in Napa County, California. The phylogenetic placement of Eschatoporiini within the Lagriinae is examined, and notes on the biology of Eschatoporis are provided.
