Cerocephalidae new status

Cerocephalinae Gahan, 1946. Type genus: Cerocephala Westwood, 1832.

Diagnosis.

Antenna with at most 10 flagellomeres and at most 3 clavomeres. Intertorular prominence present (Fig. 6 ). Eyes not ventrally divergent. Clypeus without transverse subapical groove. Labrum hidden behind clypeus, flexible. Mandibles with 2 or more teeth. Subforaminal bridge with a postgenal bridge occurring dorsal to the hypostoma. Mesoscutellum with frenum indicated at least laterally, although this may be very subtle. Mesopleural area without an expanded acropleuron; mesepimeron extending over anterior margin of metapleuron (Fig. 7 ). All legs with 5 tarsomeres; protibial spur stout and curved; basitarsal comb longitudinal. Metasoma with syntergum, therefore without epipygium.

Discussion.

Cerocephalidae differ from most other Chalcidoidea in having an intertorular prominence, although a few exceptional taxa exist across the superfamily that have a similar prominence, such as some Haltichellinae ( Chalcididae ). However, these exceptions can be distinguished from Cerocephalidae using other features mentioned in the diagnosis. Otherwise, Cerocephalidae bear little resemblance to other families, being somewhat similar to Spalangiidae , Storeyinae , and some Eulophidae , but without most diagnostic features of those families.
