Diopsidae - stalk-eyed flies Gobryidae Megamerinidae Nothybidae Psilidae - rust flies Somatiidae Syringogastridae The Diopsoidea are a small but diverse cosmopolitan superfamily of acalyptrate muscoids, especially prevalent in the tropics.

[1] As flies, Diopsoidea undergo complete metamorphosis with the four life stages of egg, larva, pupa and adult.

The adult stage has three body segments (head, thorax and abdomen), three pairs of legs and one pair of wings.

[2] Some features that distinguish adult Diopsoidea from other flies are: a well-sclerotised face, antennae usually deflexed to strongly elbowed (if not, then either the fore or hind femur is entirely swollen), ocelli positioned near the vertex of the head, no katepisternal setae, wing veins R2+3 and R4+5 subparallel or slightly convergent apically, and the wing anal cell being comparable in size to the subcostal cell.
