Platystomatinae

Platystomatinae is a subfamily of flies (Diptera) in the family Platystomatidae (Signal flies) that includes 80 genera, the largest subfamily with at last estimate, species globally.

Subfamily classification

The Platystomatidae were comprehensively divided into five subfamilies, but more recent reviews of morphology suggest that some aspects of this classification are unsatisfactory. This led to reducing the number of subfamilies to four, being the Plastotephritinae, Platystomatinae, Scholastinae and Trapherinae Angitulinae being subsumed into Platystomatinae.
The most relevant diagnostic characters include: both the upper and lower calypters form a distinct lobe (in some genera these are equally undeveloped); the katepisternal setae absent; tergite 5 is well-developed; elongate terminal filaments on the sclerotised glans of the male distiphallus, each terminating in a gonopore.

Biology

Members of the family Platystomatidae tend to occur in forest and forest margin habitat types, preferring shaded, densely-vegetated locations, while a few known from grassland or agricultural environments, sand dunes and other vegetation types. Adults of some genera can be found resting on the underside of foliage, while others utilise cryptic colouration and speckled wing patterns to escape detection on bark or rock surfaces.

Adults may be attracted to malodorous substances and decay, faeces, sap runs, decaying fruit, decaying snails and even human sweat in the case of ''Lamprogaster'' Macquart and ''Rivellia'' Robineau-Desvoidy.

Larvae are found on fresh and decaying vegetation, fruit, sugar cane, maize, coconuts, tree sap, carrion, human corpses, and root nodules, particularly in the genus ''Rivellia'', which has economic implications for legume crops. There is a record in the Australian Museum (Sydney) of larvae of the genus ''Elassogaster'' attacking eggs capsules of migratory locust (Locusta migratoria).

Biogeography

The largest concentration of Platystomatinae undoubtedly occurs in the Australasian region, followed closely by the Afrotropical region. The number of genera and species in the Oriental, European, Nearctic and NeotropicalWhittington, A E (2010). hapter67. Platystomatidae (Signal flies). 903-907. In: Brown, B V, Borkent, A, Cumming, J M, Wood, D M, Woodley, N E & Zumbado, M A (eds.) "Manual of Central American Diptera". 2. faunas are much more restricted.

Some genera are widely distributed over more than one region. For example, ''Plagiostenopterina'' Hendel, 1912, is widely distributed in the Old World tropics (Australasian, Oriental and Afrotropical regions) and ''Rivellia'' Robineau-Desvoidy, 1830 is almost cosmopolitan, although numbers of species in Europe are very restricted. Taxonomic revisions on such genera need to examine the wider implications of these broad distributions. Other genera a known from just a single location. ''Bama'' McAlpine, 2001, for example, is known only from New Guinea.
