Introduction

Chloropidae are a large family of acalyptrate flies with more than 2000 species described worldwide. Currently for Australia 322 species are described representing 49 genera. They are generally small flies ranging from 1.5-5.0 mm in body length. In recent literature, new species have regularly been described from other zoogeographical regions, and there are many undescribed species residing in institutional collections. Chloropid flies are characterised by a large triangular plate on the frons.

Becker's (1911) monograph of the Indo-Australian fauna included numerous Australian species. Many of the early descriptions of the Australian chloropid fauna appear in Malloch's series of papers (1913-1941). In 1977, Andersson published a taxonomic and phylogenetic review on the Old World genera of Chloropidae. More recently, significant additions to the Australian fauna include Spencer's (1986) review of Australian Chloropinae (keys to genera and species) and Ismay's (1993) revision of the genera Tricimba and Aprometopis (keys to genera and species of Oscinellinae).

Chloropid larval habits are diverse (see Ferrar, 1988). They are known to be saprophagous and phytophagous. Others are gall inducers, predators of eggs (e.g. spider egg sacs, see Hickman, 1971) and root aphids, and some are parasites. Some species are pests of cereal crops and pasture grasses. Oscinella frit is a pest of wheat, and is of significant economic importance. In South-east Asia, species of the genus Siphunculina are known to be attracted to mammalian eyes (including humans), as well as being vectors of eye disease. Some species of Thaumatomyia and Chloropisca are probably of economic benefit, their larvae being predators of plant-damaging bugs such as aphids and scale insects.There has not been a great deal written about the biology of the Australian chloropid fauna; Hoskin & McCallum (2007) investigated parasitism of frogs by Batrachomyia in northern Australia.

Unidentified acalyptrate flies thought to represent the genera Pseudeurina De Meijere, 1904 have also been recorded in Queensland (Sabrosky, 1989).
