Holoparamecus Curtis, 1833: 185 .

Type species: Holoparamecus depressus Curtis, 1833 .

This genus is distributed throughout the world ( Tomaszewska 2000). In the United States 6 species are known, primarily collected from forest litter or with flight intercept traps ( Skelley & Leschen 2001). Holoparamecus gabrielae Rücker was found in bat guano inside a cave in Veracruz State ( Rücker 2003). Rojas (1989) reported an unidentified species of Holoparamecus as associated with the debris of Atta mexicana (Smith) in an arid zone of Querétaro. Navarrete-Heredia (2001), however, considers that the occurence of these beetles in this particular habitat is accidental so this association needs to be fully investigated. There is no updated work that could help in identification of the Mexican species. In Tomaszewska (2000) a detailed generic description is presented. Four species are known from México.
