Lauxanioidea

Aphid fly Leucopis sp., copyright ICAR-National Bureau of Agricultural Insect Resources.

Belongs within: Schizophora.
Contains: Lauxaniidae.

The Lauxanioidea are a group of small to medium-sized flies characterised by convergent postvertical bristles, a shortened anal vein that does not reach the wing margin, and the presence of only a single dorsal sclerite between the sixth tergite and the periandrium in the male. They include the Celyphidae, beetle flies, a group of tropical flies with an enlarged scutellum overhanging the abdomen, beneath which the wings are folded at rest.

The Chamaemyiidae are small stocky flies with larvae predatory on plant-sucking bugs such as aphids and scales. Members of the Holarctic chamaemyiid genus Cremifania lack a prescutellum and presutural supra-alar seta, and have a large, darkly clouded pterostigmal space on the wing. Other chamaemyiids in the subfamily Chamaemyiinae have the supra-alar seta and usually the prescutellum, and the pterostigmal space is smaller and usually only lightly clouded. Within the Chamaemyiinae, the Chamaemyiini have an elongate, posteriorly tapering body form, postocellar setae and strong ocellar setae. The Leucopini have a more compact body with postocellar setae absent and ocellar setae absent or small (Gaimari 2010).
