Morphological evidence and information from collection labels suggest that these beetles are predators of wood-infesting insects. Some show bark-like cryptic coloration and a body form that implies involvement in Batesian mimicry with Lampyridae. Pelonium species are thought to have originated from South American ancestors that eventually generated 15 lines of evolution as indicated via a computer generated phylogeny. This treatise includes a morphological analysis, review of natural history, key to species, discussion of species-group evolution, 199 line drawings, 8 electron micrographs, 8 Auto Montage morphological illustrations, 89 figures of male terminalia, 18 distribution maps, and 105 habitus photographs. K e y w o r d s : Checkered beetles, evolution, systematics, phylogeny, natural history, key to species.

Lectotype-Designation für Juniorsynonyme: Opilus auripennis HOPE, Enoplium fulvicornis LUCAS, Pelonium atronotatum PIC, Pelonium corporaali PIC, Pelonium lateapicale PIC, Pelonium praeustum SPINOLA, Pelonium multinotatum PIC, Pelonium separatum PIC, Pelonium tarsale SCHENKLING, und Pelonium unipunctatum PIC. Morphologische Belege sowie die Informationen der Fundortetiketten weisen darauf hin, dass die Käfer Räuber holzbewohnender Insekten sind. Einige zeigen eine borkenähnliche, kryptische Färbung und eine Körperform, die auf Bates'sches Mimikry mit Lampyridae hindeutet. Man kann davon ausgehen, dass Pelonium-Arten sich aus südamerikanischen Vorfahren entwickelt und möglicherweise 15 evolutive Linien hervorgebracht haben, wie anhand der computer-basierten Phylogenie angedeutet wird. Diese Bearbeitung beinhaltet eine morphologische Analyse, eine Übersicht zur Natur- geschichte, einen Bestimmungsschlüssel der Arten, eine Diskussion zur Evolution der Artengruppen, 199 Zeichnungen, 8 elektronenmikroskopische Aufnahmen, 8 morpholo- gische Automontage-Illustrationen, 89 Abbildungen männlicher Geschlechtsorgane, 18 Verbreitungskarten und 105 Habitusfotos.
