Abstract

Within the suborder Calymenina, the classification of several Ordovician trilobite genera is discussed. Neseuretus, Calymenella and Platycoryphe are regarded as belonging to the family Calymenidae, while Kerfornella, Plaesiacomia and Brongniartella (subfamily Kerfornellinae) areattributed to the family Homalonotidae. Post-Ordovician homalonotids may have derived from the kerfornellines through Brongniartella or a similar form. The author's opinion is mainly based on the morphology ofthe occipital ring and thoracic rachis, and on the morphology of the thoracic pleurae. The well-developed articulating bosses and the corresponding sockets on the thoracic pleurae of calymenids clearly separate them from homalonotid trilobites (Henry 1980a).
