Labeninae


The Labeninae is a subfamily within the parasitic wasp family Ichneumonidae. There are 12 extant genera, grouped within four tribes, that exhibit a predominantly Gondwanan distribution - most genera and species are found in Australia and South America. A few species of Labena and Grotea are found in North America, with hypotheses suggesting that the group radiated on Gondwanaland prior to the separation of Australia but after the separation of Africa/India/Madagascar.
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 Orthognatheliini 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.
