Labeninae

The Labeninae is a subfamily within the parasitoid wasp family Ichneumonidae. The family is divided into 12 extant genera grouped within four tribes.^[1]

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.^[1]

Biology

Some species from the tribe Labenini have been reared from wood-boring beetles of the Coleopteran families Buprestidae, Cerambycidae, and Curculionidae.^[1][2] Members of the tribe Groteini parasitize solitary bees; Labium wasps are known to parasitise ground-nesting, solitary bees,^[3][4] while Grotea are known parasitoids of cavity-nesting, solitary bees.^[1][5] Species of Poecilocryptus are thought to be phytophagous, due to adaptations of the larval head capsule.^[6] However, as with much of the Ichneumonidae, knowledge of many labenine species' ecology, biology, and evolution is extremely limited or completely lacking.^{[citation needed]}
