Calosoma aethiops (Jeannel, 1940) as a new synonym of Calosoma imbricatum hottentotum Chaudoir, 1852, a new status of Calosoma roeschkei Breuning, 1927, and a revision of the Calosoma senegalense group sensu Häckel, 2012 (Coleoptera: Carabidae: Carabini). Conducted is a taxonomic revision of the Calosoma senegalense group sensu Häckel, 2012. Placed in the group sensu stricto are four species: Calosoma planicolle Chaudoir, 1869, Calosoma scabrosum Chaudoir, 1843, Calosoma senegalense Dejean, 1831, and Ctenosta strandi Breuning, 1934. Calosoma aethiops Jeannel, 1940 is synonymized with Calosoma imbricatum hottentotum Chaudoir, 1852, and Calosoma roeschkei Breuning, 1927 is newly regarded as a subspecies of Calosoma scabrosum. The taxonomic conclusions are based on morphometry of the holotypes and 10 male and 10 female specimens of each taxon, and on morphology of the aedeagus including inflated endophalus.

The giant ground beetle genus Calosoma (Coleoptera, Carabidae) comprises ca. 120 species distributed worldwide. About half of the species in this genus are flightless due to a process of wing reduction likely resulting from the colonization of remote habitats such as oceanic islands, highlands, and deserts.

Yet, whether these deterministic evolutionary trajectories within islands are driven by an initial, singular divergence and the subsequent exchange of individuals and adaptive genetic variation between islands remains unclear. Here, we study a gradual, repeated evolution of low-dispersive highland ecotypes from a dispersive lowland ecotype of beetles along the island progression of the Galápagos.

Calosoma maximoviczi, a predatory pest beetle, poses a significant threat to wild silk farm production due to its predation on wild silkworms. Given the coexistence of this species with beneficial silkworms in the farm orchards, chemical pesticides are not an ideal solution for controlling its population. In this study, we employed a comprehensive multi-target RNA interference (RNAi) approach to disrupt the olfactory perception of C.

Background: The black carabid beetle Calosoma maximoviczi is a successful predator that serves as both a beneficial insect and a severe threat to economic herbivores. Its hunting technique relies heavily on olfaction, but the underlying mechanism has not been studied. Here, we report the electrophysiological, ecological and molecular traits of bioactive components identified from a comprehensive panel of natural odorants in the beetle-prey-plant system.
