Antrocephalus is an Old World genus of wasps (with a single species introduced to South America) that mostly parasitises Lepidoptera. Mature wasps emerge from the host pupa (Bouček 1988).
Characters (from Bouček 1988): Frons at inner margins of eyes with distinct carina on either side, clearly curving in before lateral ocelli and uniting behind median ocellus; pronotum frequently with keels running obliquely from anterior shoulders towards a point just before middle of posterior margin but there ending as two tubercles separated by a narrow median depression; axillae separated from each other by the base of scutellum; forewing with postmarginal vein distinctly developed, marginal vein virtually on the very margin of wing; hind femur sometimes with comb beginning in proximal third on a very low tooth, then for a distance almost straight before a subapical lobe, or comb shortened.
