Five species of Haltichella Spinola are recognized in the Nearctic region: H. onatas (Walker), H. ornaticornis Cameron, H. perpulcra (Walsh), H. rhyacionia Gahan, and H. xanticles (Walker). The females and males of each species are diagnosed. A neotype is designated for H. perpulcra . The males of H. onatas, H. ornaticornis, H. perpulcra , and H. xanticles were previously undescribed; voucher specimens of each are designated. Biological and distributional information is summarized for each species. A key to the Nearctic species and characters to distinguish Haltichella from other Nearctic Chalcididae are presented.
