Campichoetidae

~Diastatidae.

Adult insects. Winged. The face in lateral view not deeply excavated between the antennae and the edge of the mouth. Antennae 3 segmented (the third segment long, reaching almost to the edge of the mouth); ‘modified’; aristate; the arista dorsal. The arista not forked at the tip. The second antennal segment not grooved. The third segment elongated. Ptilinal suture clearly defined. Mouthparts functional. The maxillary palps 1 segmented; porrect. Vibrissae present. Thorax without a continuous dorsal suture; without well defined posterior calli. Wings with a discal cell to without a discal cell (? - cf. Diastatidae?); with a closed anal cell. The anal cell short. The costa with two breaks (near the humeral cross vein, and near the apex of vein 1). Wings with the lower calypter much reduced or absent. Tibiae with a dorsal pre-apical bristle. Hind tibiae without strong bristles in the basal 4/5.

Larvae and pupae. The larvae acephalic. The pupae enclosed within a puparium.

Comments. Distinguishable from Diastatidae by the long third antennal segment, and in having two inset, upswept orbital bristles instead of one.

Classification. Suborder Brachycera; Division Muscomorpha Schizophora Acalyptratae; Superfamily Ephydroidea.

British representation. 2 species in Britain. Genera 1; Campichoeta.
