Abstract

It is established that Musca conformis Fallén, 1825, in the combination Pegomya conformis (Fallén), is a valid senior synonym of P. esuriens (Meigen).

Abstract

Botanophila helviana n.sp. is described and figured on basis of a small material of both sexes from Denmark. Its relationships within the large genus Botanophila are unsettled, and the larval habits are unknown. However, the structure of the female terminalia suggests a larval association with the floral parts of some dicotyledonous flowering plant.

Abstract

Material of a small thyreophorine fly collected on the carcass of a horse in Kashmir is referred to Centrophlebomyia Hendel and found probably identical with Thyreophora anthropophaga Robineau-Desvoidy, a species with has remained unrecognized since its description in 1830. It is redescribed and compared with C. furcata (Fabricius).

Abstract

Fallén's nominal species of Anthomyiidae are revised. Primary types for all 27 species have been examined; these are deposited in the Naturhistoriska Riksmuseum, Stockholm (21), and in the Museum of Zoology, Lund (6). The nominal species of European Emmesomyia Malloch are revised and diagnostic features of the females are described and figured. — Emmesomyia socia (Fallén) is a valid, senior synonym of E. villica (Meígen); the name E. grisea (Robineau-Desvoidy) is proposed for E. socia auctt. (partim), nec Fallén. Pegomya laticornis (Fallén) is a valid, senior synonym of P. genupuncta Stein.

Abstract

The Pegomya hyoscyami species complex, which contains the economically important beet and spinach leaf-miners, is defined and taxonomically revised. Four distinct species are recognized by differences in the adult morphology of both sexes: Pegomya betae (Curtis), P. cunicularia (Rondani), P. exilis (Meigen), and P. hyoscyami (Panzer). A key for identification, diagnoses, figures of the male and female genitalia, and distribution records are provided. The nomenclature adopted here is a result of a critical review of 21 relevant species-group names. Five lectotypes are designated and four new synonymies are established; five names are considered nomina dubia and one is a nomen nudum. All four species occur in Europe, whilst only two are known from North America (betae, hyoscyami) and Japan (cunicularia, exilis).

Abstract

The monophyly of the following anthomyiid aggregates is substantiated: The Myopininae/ Myopinini = (Enneastigma Stein + Calythea Schnabl & Dziedzicki) + (Pegoplata Schnabl & Dziedzicki + Myopina Robineau-Desvoidy). The Afrotropical species tarsata (Adams), ornata (Bezzi) and two Oriental species, fulva (Malloch), henanensis (Ge & Fan), all currently recognized in Nupedia Karl, are either referable to Enneastigma or to a new genus in the Enneastigma + Calythea lineage. The recent inclusion of Nupedia in Pegoplata is accepted, but it is pointed out that Pegoplata s. lat. is probably paraphyletic in terms of Myopina. The monophyly of Pegoplata (section cuticornis) is confirmed, and it is argued that its sister group is section acutipennis. Section cuticornis is found to include 1 Holarctic, 2 Nearctic, and 6-7 Palearctic species of which 4 new ones are described from the Mediterranean: P. granadensis sp. n. from Sierra Nevada in Spain, and P. freidbergi sp. n., P. grandis sp. n. and P. hermonensis sp. n. from Mt. Hermon at the Lebanese/Syrian border. The Mediterranean species, which are shown to constitute a monophyletic group, are keyed and subjected to cladistic and biogeographic analyses.

Abstract

Musca vagans Panzer, 1798, is restored as a valid name in the binomen Hylemya vagans (Panzer, 1798) with Musca strigosa Fabricius, 1794, nec Gmelin, 1790, and Hylemya strenua Robineau-Desvoidy, 1830, as synonyms. Phaonia falleni n. nom. is proposed for Musca vagans Fallén, 1825, nec Panzer, 1798.

Abstract

Cryptophyra lundbecki n. gen. et n. sp., is described from both sexes from Denmark. The genus is readily assigned to the ubfamily Muscinae, tribe Hydrotaeini. Character-states of diagnostic and phylogenetic importance are discussed. In conclusion, it is suggested that morphological evidence points to affinities with Megophyra Emden, Hydrotaea Rob.-Desv. or a more extensive Hydrotaea-group.

Abstract

Enneastigma is a small genus of myopinine anthomyiids which comprises five species in the Mediterranean subregion (E. compressum Stein, E. rarum sp. n., E. rufitibia sp. n., E. triplex Loew, E. triseriatum Stein) and two species in SE Palearctic part of China (E. pilosiventrosum Fan & Chen, E. shanghaiensis Fan & Chen). All species appear to be univoltine and only active during the cooler parts of the season. The larvae may all be coprophagous. The Mediterranean species are revised with keys to males and females and illustrated descriptions of males, females and eggs. One lectotype is designated. A cladistic analysis was conducted which also included the Chinese species. This resulted in a single, most parsimonious phylogeny. The resulting area cladogram was used to assess the alternative methods for estimating ancestral areas as proposed recently by K. Bremer and F. Ronquist. It is concluded that the best results are obtained by using a refined Ronquist analysis.
