Interpretive Summary: Islands are known to be poor in bee diversity. The Galapagos Islands are no exception. Only one species has been thought to occupy the islands, a carpenter bee. Recently a carder bee was found on the islands. Now a third species, the leafcutter bee Megachile timberlakei¸ previously known only from the Hawaiian Islands, is documented. Its presence is thought to be due to an accidental introduction. Characters to separate this adventive bee from other leafcutter bees is provided.
Technical Abstract:
The Galapagos Archipelago has been thought to be extremely depauperate in bees, with only one species known, Xylocopa darwini. Recently a second species, Anthidium vigintiduopunctatum, was detected. Here we document a third species, Megachile timberlakei. We provide floral records as well as a diagnosis and comparative comments that will assist bee researchers to easily recognize this species from other native and adventive Megachile Latreille to the Americas. We also discuss the possible routes to the Galapagos.
