Strongylophthalmyiids are an infrequently encountered group of small dark-colored, thin-bodied acalyptrate flies related to the Psilidae, Tanypezidae, and Micropezidae. Their family status has been debated. Griffiths (1972), Cogan (1980a), and D.K. McAlpine (in litt.) refer Strongylophthalmyia to the Tanypezidae; however, I here follow recent treatments (e.g., Steyskal 1987) in retaining separate family status for this monogeneric family pending a phylogenetic analysis of it and related families.

The biology of these flies is poorly known. Krivosheina (1981) records larvae from under bark in the USSR, and unpublished collecting records from New Guinea show them to mimic the behavior of ants with which they were collected on banana leaves. They have also been collected from leaves of Alocasia in Australia.

The family is comprised of two genera: Strongylophthalymia (54 spp.) and Nartshukia Shatalkin (1 sp.). These flies are most commonly found in the southeastern Oriental Region (less commonly in the Palearctic Region), but unpublished records show that many species occur also throughout Melanesia and Australia to Fiji. Four species in the genus Strongylophthalmyia are recorded from the regions covered here, though many more undescribed species are known from both New Guinea and Australia.
