The previously monotypic genus Laccoproctus Schoenherr is revised. In addition to the one known Mexican species, Laccoproctus acalloides Boheman, nine new species are described as follows: Laccoproctus anneae Anderson and O'Brien, new species (Mexico: Guerrero, Hidalgo, Puebla, San Luis Potosí, Veracruz); Laccoproctus burkei Anderson and O'Brien, new species (Mexico: Veracruz, Chiapas); Laccoproctus chiapanecus Anderson and O'Brien, new species (Mexico: Chiapas); Laccoproctus elegantulus Anderson and O'Brien, new species (Mexico: Hidalgo); Laccoproctus nigrinus Anderson and O'Brien, new species (Guatemala); Laccoproctus occidentalis Anderson and O'Brien, new species (Mexico: Colima); Laccoproctus similis Anderson and O'Brien, new species (Mexico: Puebla); Laccoproctus truncatus Anderson and O'Brien, new species (Mexico: Estado de México); and Laccoproctus zunilensis Anderson and O'Brien, new species (Guatemala). A key to the now 10 known species is presented. The genus is proposed as closely related to Aenesias Champion, Lepilius Champion, Enomides Champion, and Plumolepilius Barrios-Izas and Anderson and placed in Molytinae, Conotrachelini (new placement). No detailed information on natural history is available. Specimens of L. elegantulus were collected on trailside ferns at night; specimens of L. chiapanecus were associated with Cedrela odorata L. (‘cedro’); and specimens of other species were collected under bark, on wood, on oak stumps, and on fence posts.
