Life style parasitic (the larvae being parasites of other arthropods).

Adult insects. Small. Antennae 2–6 segmented; ‘modified’; aristate; the arista dorsal (pubescent or shortly hairy). The second antennal segment distinctly grooved above. Ptilinal suture clearly defined. Eyes rounded, well separated (but close, in the males). Mouthparts functional; non-piercing (?). The maxillary palps 1 segmented; porrect. Thorax with the dorsal suture continuous across the middle; with well defined posterior calli. Hypopleural bristles present. Wings with a discal cell; with a closed anal cell. The anal cell short. Wings without a sharp bend in vein 4; with a well developed lower calypter (but this narrow); patterned, or unpatterned (sometimes heavily suffused or marked with dark colouring). Neither parasitic nor predatory (?).
