Ctenostylidae
Family of flies
The enigmatic fly family Ctenostylidae is a small group of very rare flies formerly included in the family Pyrgotidae ; the principal reason for their inclusion in the Pyrgotidae was the absence of ocelli, a feature originally thought to be a unique defining feature ("autapomorphy") of the Pyrgotidae. Subsequent careful analysis has revealed that this anatomical feature shared with Pyrgotidae may not be indicative of a close relationship, and even the inclusion of Ctenostylidae within the superfamily Tephritoidea was cast into doubt, leaving this as the only family of Acalyptratae presently unassignable to superfamily.
