What is "strongylophthalmyiidae"

The Strongylophthalmyiidae are a small family of about 45 species of slender, long-legged flies, the majority of which occur in the Oriental and Australasian regions. They are divided into two genera, the monotypic Southeast Asian genus Nartshukia Shatalkin, 1993 and Strongylophthalmyia Heller, 1902. The relationships of the group are obscure; formerly the genus Strongylophthalmyia was classified with the Psilidae, and some recent classifications place it within the Tanypezidae. Little is known of their biology, but many species seem to be associated with rotting bark.
