The Diptera of Bermuda.
The Diptera of Bermuda are enumerated based on a new faunal survey conducted between 1987 and 1991. All previous literature records have been verified as far as possible. 258 species in 44 families have been recorded. There are 188 named species, 46 unnamed species, 20 doubtful records, and 4 interceptions that have not become established (Pollenia rudis (Calliphoridae), Rhopalomyia chrysanthemi (Cecidomyiidae), Tritoxa flexa (Otitidae) and Anastrepha obliqua (Tephritidae)). 17 species are probable endemics, of which 7 are possibly extinct as they have not been recently collected. Tomosvaryella albiseta (Pipunculidae) is removed from synonymy with T. subvirescens. New records include, amongst others, Liriomyza trifolii (Agromyzidae), Lucilia cuprina and L. rica (Calliphoridae), Drosophila hydei, D. simulans and Scaptomyza pallida (Drosophilidae), Hydrellia griseola (Ephydridae), Fannia canicularis (Fanniidae), Brontaea cilifera, Euryomma peregrinum, Haematobia irritans, Neodexiopsis ovata and Schoenomyza dorsalis (Muscidae), Megaselia spp. (Phoridae), Psychoda cinerea (Psychodidae), Dictya floridensis (Sciomyzidae), Coproica acutangula, C. vagans, Pullimosina heteroneura, Rachispoda fuscipennis and Spinilimosina brevicostata (Sphaeroceridae).
