Diagnosis (From Pont & Meier, 2002):

Adult cynipsea can be recognised in the male sex by the characteristically incised fore tibia (see legs). The female has katepisternum wholly pruinose and meron glossy on posterior half (see habitus), and can usually be distinguished from neocynipsea female by the absence of a submedian anterior seta on mid femur.



(From Ozerov, 2005)
cynipsea Linnaeus, 1758: 559 (Musca). Type locality: "habitat in Europa "; Holotype ♂, in LSL.

elongata Moller, 1764: 85 (Musca). Type locality: "in hortis " [from title: Sjaelland, Frederiksdal (DENMARK)]; Syntypes, sex not stated, presumed destroyed.

hilaris Meigen, 1826: 288 (Sepsis). Type locality: not stated [probably GERMANY: Stolberg]; Holotype Female, in MNHNP.

barbipes Meigen, 1826: 289 (Sepsis). Type locality: not stated [probably GERMANY: Stolberg]; Holotype Female, in MNHNP.

vivida Robineau-Desvoidy, 1830: 742 (Micropeza). Type locality: not stated [FRANCE, probably Saint-Sauveur]; Syntypes, sex not stated, presumed destroyed.

incisa Strobl, 1894: 106 [as variety of cynipsea] (Sepsis). Type localities: Kaiserau, Scheibleggerhochalpe, and Bösenstein (AUSTRIA); Syntypes 10 ♂, in NMBAA.

(From Pont & Meier, 2002)
Musca cynipsea: Pont has studied the two specimens under this name in Linnaeus’ collection (Linnean Society of London, U.K.), under Musca no. 113 in Diptera box 15. Both are on identical, medium-sized pins. One is a ♂, which at some time became detached from its pin and has been glued back on. The left wing and left mid leg are missing. It has Linnaeus’ own label ‘cynipsea 87.’, which is the number of this species in his Systema Naturae (1758).This specimen was not seen by Haliday (1851). There is every indication that this is Linnaeus’ original specimen, as his brief description fits very well: he mentions a ventral tooth on fore femur, and so was clearly looking at a ♂, and the constricted syntergite 1+2 matches his descriptions (1758: 599; 1761: 459). The second specimen is a ♀, has no Linnaean label, and does not agree with Linnaeus’ description as the fore femur is simple and not dentate. The ♂ is therefore considered to be the holotype. Unfortunately, however, the holotype does not belong to cynipsea, as understood for well over half a century and as de?ned in the present paper, but to fulgens: the fore femur has the characteristic armature of fulgens, and the fore tibia lacks the ventral incision that characterises cynipsea. The past decades have seen a burgeoning of the literature on the two species cynipsea and fulgens, as aspects of their anatomy, behaviour and reproductive strategies have been studied, not to mention the very considerable faunistic, taxonomic and biological literature, and we can see no useful purpose in now seeking to change the names of these two well-known species. We propose to continue using the name cynipsea in its traditional sense, for the most abundant and widespread Europe and coprophilous species with incised male fore tibia, and a ruling by the International Commission for Zoological Nomenclature should be sought to conserve this usage.

(From Pont & Meier, 2002) - With focus on European Distribution
Widespread and common throughout Fennoscandia. Denmark: all provinces (e.g. Hammer, 1941: passim; Lyneborg, 1965: 231). Norway: østfold and A to Finnmark, but with few published postSiebke records (e.g. Strand, 1913: 325; Hennig, 1949: 79). Sweden: Skåne to Torne Lappmark (e.g. Zetterstedt, 1847: 2284; Ringdahl, 1931: 25; 1951: 142; 1954: 231). Finland: Alandia and Regio aboensis to north Lapland (e.g. Frey, 1908: 583; Krogerus, 1960: 77). Also in the adjacent areas of Russia as far north as Arkhangelsk (Shtakel’berg, 1958: 134). Throughout Europe, North Africa, but not the Middle East except Turkey and Syria, eastwards to Mongolia (Zuska and Pont, 1984: 159), through Siberia to the Far East province of Russia (Ozerov, 1999: 568) and Hokkaido (Iwasa, 1980: 404; 1995: 796). Records are from May to early September in the north, April to October in the south, with occasional records from the winter months of overwintering adults. In Austria, Czerny (1903: 239) found adult cynipsea active during mild weather on 68 January 1903, but his specimens were most probably fulgens.
