Revision of the Genus Laccoproctus Schoenherr (Coleoptera: Curculionidae: Molytinae: Conotrachelini), with New Species from Mexico and Guatemala

Abstract

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 Potosi, 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 Mexico); 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.
