Parataruma, a New Genus of Neotropical Crabronini (Hymenoptera, Sphecidae)

Crabronini are a diverse group of wasps that are found world wide.Typical members of this tribe can be recognized by the single forewing submarginal cell, large cuboidal head and ventrally con- verging eyes.The new genus, Parataruma, is found in lowland neotropical forest in widely separated localities.This distribution can probably be explained in several ways.Most of the neotropical lowland forest has been poorly collected, and much of it has been destroyed.In addition, these wasps are small and darkly colored, making them difficult to observe.
