- Caught in the act: pollination of sexually deceptive trap-flowers by fungus gnats in Pterostylis (Orchidaceae). Phillips, Ryan D.; Scaccabarozzi, Daniela; Retter, Bryony A.; Hayes, Christine; Brown, Graham R.; Dixon, Kingsley W.; Peakall, Rod // Annals of Botany;Mar2014, Vol. 113 Issue 4, p629
Background and Aims Pterostylis is an Australasian terrestrial orchid genus of more than 400 species, most of which use a motile, touch-sensitive labellum to trap dipteran pollinators. Despite studies dating back to 1872, the mechanism of pollinator attraction has remained elusive. This study...

Five new species of scuttle fly are reported from caves in Nevada, USA, namely Aenigmatias bakerae Disney, Megaselia excuniculus Disney, M. krejcae Disney, M. folliculorum Disney, M. necpleuralis Disney and a female Megaselia that can not be named until linked to its male.
- First record of Megaselia rufipes (Meigen, 1804) (Diptera: Phoridae) from Uruguay with notes on biology. Gonzalez-Vainer, Patricia; Castro, Manuel; Remedios, Mónica; Morelli, Enrique; Martínez, María; Disney, R. Henry L. // CheckList;2012, Vol. 8 Issue 6, p1299
Megaselia rufipes (Meigen, 1804) is recorded for the first time in Uruguay, extending the Neotropical distribution of this taxon. The specimens were collected in a cemetery in Montevideo with ball-traps baited with carrion, placed inside crypts, from June to November 2011. Records of M. rufipes...
- New Records of the Rarely Collected Ant-decapitating Fly Apocephalus tenuipes Borgmeier (Diptera: Phoridae). Hill, JoVonn G.; Brown, Brian V. // Southeastern Naturalist;2006, Vol. 5 Issue 2, p367
The ant-decapitating fly Apocephalus tenuipes (Diptera: Phoridae) was known previously only from two Florida specimens. Here we report two additional Florida records and a Mississippi record that represents a significant range extension. Field observations of A. tenuipes are presented as well.

Diplonevra longifistula sp. n., D. meridafricana sp. n., D. stuckenbergi sp. n., Phalacrotophora petersoni sp. n. and Ph. stuckenbergi sp. are described. A revised key to Afrotropical Diplonevra species and a key to Afrotropical species of Phalacrotophora are provided.
- Observations on Antennal Morphology in Diptera, with Particular Reference to the Articular Surfaces between Segments 2 and 3 in the Cyclorrhapha. McAlpine, David K. // Records of the Australian Museum;11/30/2011, Vol. 63 Issue 2/3, p113
The main features of antennal segments 2 and 3 seen in the higher Diptera are described, including many that are not or inadequately covered in available publications. The following terms are introduced or clarified: for segment 2 or the pedicel--annular ridge, caestus, chin, collar, conus,...
- An unusually rich scuttle fly fauna (Diptera, Phoridae) from north of the Arctic Circle in the Kola Peninsula, N. W. Russia. Disney, R. H. L. // ZooKeys;2013, Issue 342, p45
64 species of Phoridae, in 6 genera, are reported from the Kola Peninsula, north of the Arctic Circle. The new species Megaselia elenae and M. kozlovi are described. 33 species of Megaselia, only known from females, are given code numbers. Keys to the species of all the females of Megaselia and...
- The South African keystone pollinator Moegistorhynchus longirostris (Wiedemann, 1819) (Diptera: Nemestrinidae): notes on biology, biogeography and proboscis length variation. Barraclough, David; Slotow, Rob // African Invertebrates;2010, Vol. 51 Issue 2, p397
Moegistorhynchus longirostris Wiedemann, 1819 has the longest proboscis relative to body size of all known insects. It is a keystone species along the west coast of South Africa, where it pollinates, partly or exclusively, the long-tubed flowers of at least 20 species of Iridaceae, Geraniaceae...
