A new fossil species of the crabronid wasp genus Tracheliodes (Hymenoptera: Crabronidae) from Dominican amber

ABSTRACT The first fossil species of the wasp genus Tracheliodes from Dominican amber is described. Tracheliodes grimaldii sp. nov. is based on a single female specimen exhibiting a somewhat generalized morphology compared to the extant fauna. While the new species resembles the Neotropical species in a few characters, it does not possess the many specialized features exhibited by this species group, especially those related to the female legs. This is the 4th genus and the 7th species of apoid wasps described from Dominican amber.
