The Labeninae is a subfamily within the parasitoid wasp family Ichneumonidae. The family is divided into 12 extant genera grouped within four tribes.
Distribution
Labeninae are predominantly found in Australia and South America. A few species of Labena and Grotea are found in North America. Research suggests that the family originated on Gondwana before the break-off of Australia.
Biology
Some species from the tribe Labenini have been reared from wood-boring beetles of the Coleopteran families Buprestidae, Cerambycidae, and Curculionidae. Members of the tribe Groteini parasitize solitary bees; Labium wasps are known to parasitise ground-nesting, solitary bees, while Grotea are known parasitoids of cavity-nesting, solitary bees. Species of Poecilocryptus are thought to be phytophagous, due to adaptations of the larval head capsule. However, as with much of the Ichneumonidae, knowledge of many labenine species' ecology, biology, and evolution is extremely limited or completely lacking.
