The moderately diverse anacharitines are often among the more easily recognizable wasps within the cynipoids. They tend to be elongate, with a subtriangular head (in anterior view). In fact, the head is frequently the widest part of the animal (when viewed dorsally. The narrow petiole, so characteristic of the common Anacharis , in conjunction with a very short ovipositor, is hypothesized to be an adaptation for ‘quick strike’ oviposition into predatory Neuroptera (Buffington 2007) . The narrow petiole allows for maximum flexibility in directing the ovipositor tip; the short ovipositor requires the slightest insertion into the larval body to deposit an egg. Together, this allows the wasp to successfully oviposit before the host can mount a counter-attack. The limits of some genera are poorly circumscribed.

Biology. Primary parasitoids of aphidophagous Hemerobiidae , and possibly Chrysopidae .

Distribution. Main genera are widespread but mostly Holarctic, while the Neotropical region has several endemic genera and the Afrotropics one ( Acanthaegilopsis ). Anacharis is the most widespread with at least one species common in Australia.

Relevant literature. The research group at the University of Barcelona (led by Juli Pujade-Villar) has been very active in this taxon. Ros-Farré et al. (2000) revised Acanthaegilips and characterized the aspicerines and anacharitines; Mata-Casanova et al. (2015a) revised Xyalaspis ; other species-level treatments of Aegilips (Mata- Casanova et al. 2017; Mata-Casanova et al. 2019) and Anacharis ( Mata-Casanova et al. 2015b) ; Restrepo-Ortiz and Pujade-Villar (2010) provide a key to genera of the world. Van Noort et al. (2015) reviewed the Afrotropical species of the subfamily. Buffington et al. (2007, 2012) provided phylogenetic data on the group.
