First Documented Record for a Species of Concern, Rhadine caudata (LeConte) (Coleoptera: Carabidae: Platynini), from North Carolina, USA

摘要

Within the genus Rhadine LeConte (Coleoptera: Carabidae: Platynini), there are 60 species, the majority subterranean. Almost all of the species are located in the western United States, with Rhadine caudata (LeConte, 1863) one of only two eastern species. Rhadine caudata is a medium-sized (8–10 mm), brachypterous (incapable of flight) species easily identified by its spined elytra. It has been previously characterized as troglophilic, preying on the eggs of common cave crickets (Barr 1985).
