Reclassification of four South American species of Laemophloeus Dejean, 1835 into Charaphloeus Casey, 1916 (Coleoptera, Laemophloeidae)

The generic placement of four South American species currently assigned to the lined flat bark beetle genus Laemophloeus Dejean ( sensu lato ) (Cucujoidea, Laemophloeidae) is re-assessed based on the examination of type material. As a result, the following species are hereby transferred to the genus Charaphloeus Casey: Charaphloeus aeneus (Grouvelle, 1876), comb. nov. ; C. deletus (Grouvelle, 1896), comb. nov. ; C. gounellei (Grouvelle, 1896), comb. nov. ; and C. pilatei (Grouvelle, 1876), comb. nov. Taxonomic and nomenclatural notes are provided and lectotypes are designated for all four species. Distributional data are also synthesised. Based on the type and additional material, C. pilatei is re-described and illustrated in detail including diagnostic characters of the mouthparts and genitalic structures and its known distribution is expanded.
