The familyNothybidae contains only the genusNothybus, a group of colorful and elongatedflies. The family has been recently revised.[1]
The morphology of Nothybidae is distinctive. Theprothorax is elongated, with the front legs arising far back on thethorax, posterior to the anterior thoracicspiracles, making their heads appear to rest on a long neck. They are also distinguished by their narrow wing bases, patterned wings, rayedaristae, and the swollen subscutellum.[2] Twelve nothybid species are described. First placed inMicropezidae, Frey recognizedNothybus as deserving a suprageneric rank, and Aczel also recognized the family Nothybidae.[3] While this group is placed in theDiopsoidea, its evolutionary relationships have never been robustly tested in a modern phylogenetic framework with molecular or morphological data. It is one of the few fly families for which noDNA data are available on NCBIGenBank.
The biology of the Nothybidae is poorly known, and thelarval habitat is unknown. Some species may be larviparous, as mature larvae have been found in preserved adult female specimens.[4] Adults have been observed displaying complex hovering and courtship behavior.[5]
Species of the genusNothybus are only found in Southeast Asia.[2]
There are reports of additional undescribed species fromPapua New Guinea and theSolomon Islands.
