Revision of the cluster‐flies of thePollenia viaticaspecies‐group (Diptera: Calliphoridae)

摘要

Abstract.ThePollenia viaticaspecies‐group (=pallidaspecies‐group) is defined and described. It consists ofP.bicolorRobineau‐Desvoidy,P.bulgaricaJacentkovsk,P.fulvipalpisMacquart,P.mediterraneaGrunin,P.ruficruraRondani, stat.rev.,P.viaticaRobineau‐Desvoidy, stat.rev. (=P.pallidaRodendorf, syn.n.) andP.pontisp.n. It is mono‐phyletic, mainly on the basis of a synapomorphic ovipositor tip, and thevagabundaspecies‐group is its sister group. A key to all species is provided, the terminalia of both sexes illustrated and all taxa redescribed. Lectotypes are designated forPollenia bisulcaPandellé,P.ruficruraRondani andP.viaticaRobineau‐Desvoidy.Pollenia ruficrurais removed from its current status as a nomen dubium.Pollenia bicolorandP.pontiare western Mediterranean species, the latter also occurs in Czechoslovakia.P.fulvipalpisis endemic to France and Channel Islands.P.ruficrurais known only from Corsica and Italy.P.mediterraneais an eastern Mediterranean species reaching east to Armenia.P.bulgaricais distributed from Hungary to Caucasus.P.viaticais widespread from France, Great Britain and Southern Scandinavia to Central Asia. All species are summer or autumn species, and seem to have only one generation each year. The immature stages and life‐cycle of a species from Paris, France, named‘Pollenia rudis’by Keilin (1909, 1915) are tentatively assigned toP. viatica. It survives the winter as a first instar larva within the earthwormAllolobopho
