Revision of the Neotropical hoverfly genus Peradon Reemer (Diptera, Syrphidae, Microdontinae)

Abstract

The species of the Neotropical hoverfly genus Peradon Reemer, 2013 are revised, based on morphological characters with aid of mitochondrial DNA barcodes. The resulting number of valid species is increased to 31, of which the following seven are described as new: P. ballux Reemer, sp. nov., P. brevis Reemer, sp. nov., P. costaricensis Reemer, sp. nov., P. notialus Reemer, sp. nov., P. palpator Reemer, sp. nov., P. pompiloides Reemer, sp. nov., and P. surinamensis Reemer, sp. nov. Two new synonymies are established: Microdon langi Curran, 1925, syn. nov. and Microdon flavomarginatum Curran, 1925, syn. nov. are both junior synonyms of Mulio bidens Fabricius, 1805. A neotype is designated for Microdon diaphanus Sack, 1921. This neotype, which has been reared from an ant nest, also represents the first case of a larval record for this genus. In some species, most notably in P. bidens (Fabricius) and P. normalis (Curran), discrete and distinct colour morphs are recognized, with strongly differing colouration of wings and abdomen.

LED’s pollinate : Invloed lichtspectrum op gedrag bestuivers

“…Kijkend naar de activiteit 'foerageervlucht' richting de boekweitbloemen, lieten zowel B. terrestris als E. aeneus geen verschillen zien tussen de lichtbehandelingen. Misschien zijn de kleuren en patronen op de bloemen van aardbei en boekweit verschillend, zoals waargenomen door de bestuivers (Lunau, 1992) (Reemer, 2009).…”

Revision of the Oriental species of the hoverfly genus Paramixogaster Brunetti, 1923 (Diptera, Syrphidae, Microdontinae)

“…They are found in the Afrotropical, Oriental, and Australasian Regions ( Reemer and Ståhls 2013a ). Like most other Microdontinae , but unlike most other Syrphidae , flies of this genus are not known to visit flowers ( Reemer 2012 ). Larvae of most species are unknown, but records of a few African and Australasian species have been found in nests of ants belonging to the subfamilies Formicinae and Myrmicinae ( Hymenoptera : Formicidae ) ( Reemer 2013 ).…”
