Diagnosis.

The genus Antrocephalus is a difficult genus to define its limits. This is because the genus comes very close to Hockeria and rarely also to Kriechbaumerella . Only with extensive expertise in the taxonomy of these genera one can authoritatively identify this genus, which in future perhaps will be more reliably possible by using molecular markers.

Description.

Head with a horse shoe-shaped carina running behind anterior ocellus; scrobe fairly deep and reaching anterior ocellus; pronotum with anterior carinae and often with submedian tubercles in majority of species; apex of scutellum variable; geno-temporal margin with or without geno-temporal furrow; metasoma usually with two submedian short or long carinae in most species.

Hosts.

Pupae of Lepidoptera .

Distribution.

Europe, Asia, Australia and New Guinea. Apparently introduced in South America ( Bouček 1988b).

Variation.

There is a wide variation of the general characters. In some species the pronotal carina and tubercles are weak or absent; in a few species the scrobe is shallow, not very deep as in typical species, in some others the metasoma without basal carinae on T1 indistinct.
