Catalogue of the Diptera (Insecta) of Morocco- an annotated checklist, with distributions and a bibliography.

The faunistic knowledge of the Diptera of Morocco recorded from 1787 to 2021 is summarized and updated in this first catalogue of Moroccan Diptera species. A total of 3057 species, classified into 948 genera and 93 families (21 Nematocera and 72 Brachycera), are listed. Taxa (superfamily, family, genus and species) have been updated according to current interpretations, based on reviews in the literature, the expertise of authors and contributors, and recently conducted fieldwork.

The world Polleniidae (Diptera, Oestroidea): key to genera and checklist of species.

A key to the world genera and a checklist of the world species for the family Polleniidae, including distributions, are provided. The following taxonomic and nomenclatural changes are proposed: Lehrer, 2007 = Grunin, 1966, , Lehrer, 2007 = Villeneuve, 1911, , Jacentkovský, 1941 = Séguy, 1928, ; Malloch, 1928, (monotypic; type species Malloch) is considered a valid name and tentatively assigned to Polleniidae, giving (Malloch, 1927) as a ; (Villeneuve, 1936), is considered a valid species, and Enderlein, 1936, is considered an available name.

The Calliphoridae (Diptera) of Armenia.

A report is given on the Calliphoridae (Diptera) collected by Adrian C. Pont during recent fieldwork in Armenia. Twenty-six (26) named species have been identified, and of these 21 are newly recorded from Armenia.

Amplified fragment length polymorphism analysis supports the valid separate species status of and (Diptera: Calliphoridae).

Common DNA-based species determination methods fail to distinguish some blow flies in the forensically and medically important genus Robineau-Desvoidy. This is a practical problem, and it has also been interpreted as casting doubt on the validity of some morphologically defined species. An example is and , which co-occur in Europe whilst only has been collected in North America.

Two species of Surcouf (Diptera: Calliphoridae) new to India, with data on larval behaviour and morphology.

Surcouf (Diptera: Calliphoridae) is an Old World genus of blow flies, the larvae of which feed on egg masses in the foam nests of various species of rhacophorid tree frogs. Here, we provide the first records for India (West Bengal, Eastern India) of Séguy, 1948 and Rognes, 2015, together with new information on the behaviour and morphology of their larvae. Active surface swimming to disperse from infested nests is documented in blow fly larvae for the first time, as is the presence of a large internal air sac presumably acting as a floating aid.

Revision of the Bengalia torosa Wiedemann, 1819 species-group (Diptera: Calliphoridae), with notes on the systematic position of B. robertsi Kurahashi, 1987 and B. subnitida James, 1964.

The mainly Oriental Bengalia torosa Wiedemann species-group is revised on the basis of males. Species concepts are based on male terminalia. Monophyly of the species-group is established on the basis of two unique synapomorphies of the distiphallus.

First fossil of an oestroid fly (Diptera: Calyptratae: Oestroidea) and the dating of oestroid divergences.

Calyptrate flies include about 22,000 extant species currently classified into Hippoboscoidea (tsetse, louse, and bat flies), the muscoid grade (house flies and relatives) and the Oestroidea (blow flies, bot flies, flesh flies, and relatives). Calyptrates are abundant in nearly all terrestrial ecosystems, often playing key roles as decomposers, parasites, parasitoids, vectors of pathogens, and pollinators. For oestroids, the most diverse group within calyptrates, definitive fossils have been lacking.

The identity of Calliphora bezzii Zumpt, 1956 (Diptera, Calliphoridae).

The holotype male of a nominal species described from Italy, Calliphora bezzii Zumpt, 1956, including a microscope slide of its terminalia, was examined. The holotype is shown to belong to the Nearctic taxon Calliphora latifrons Hough, 1899. Thus, Calliphora bezzii is a junior synonym of C.

A new species of Pollenia Robineau-Desvoidy, 1830 from Jordan (Diptera: Calliphoridae: Polleniinae).

A new species, Pollenia bartaki sp. nov., assigned to the Pollenia rudis species-group in Pollenia Robineau-Desvoidy, 1830, is described on the basis of a single male specimen captured in Jordan.

The identity of Tachina westermanni Wiedemann, 1819 (Diptera: Calliphoridae or Tachinidae) with a solution to a nomenclatural problem.

Tachina westermanni Wiedemann, 1819 was based on four syntypes, two conspecific calliphorids and two conspecific tachinids. Two existing but contradictory lectotype fixations have resulted in confusion as to the correct application of the specific name westermanni Wiedemann. Evidence is presented showing that the lectotype fixation of Townsend in 1931 is valid and assigns westermanni Wiedemann to the Calliphoridae, with Pericallimyia westermanni as the valid binomen.

Revision of the frog fly genus Caiusa Surcouf, 1920 (Diptera, Calliphoridae), with a note on the identity of Plinthomyia emimelania Rondani, 1875.

The Oriental, Australasian and Oceanian genus Caiusa Surcouf, 1920 is revised, species concepts being based on male and female genitalia. A key to males for all known species, and a key to females for all except one are given. All relevant types still in existence have been studied, complete synonymies given and the geographical distribution reconsidered.

Fauna europaea: Diptera - brachycera.

Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all extant multicellular European terrestrial and freshwater animals and their geographical distribution at the level of countries and major islands (east of the Urals and excluding the Caucasus region). The Fauna Europaea project comprises about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. Fauna Europaea represents a huge effort by more than 400 contributing taxonomic specialists throughout Europe and is a unique (standard) reference suitable for many user communities in science, government, industry, nature conservation and education.

A new species in the genus Pseudorhyncomyia Peris, 1952 and the identity of P. deserticola Zumpt and Argo, 1978 (Diptera, Rhiniidae).

The genus Pseudorhyncomyia Peris, 1952 is re-described and shown to have two valid species: P. braunsi (Villeneuve, 1920) and P. aethiopica sp.

The Calliphoridae (Blowflies) (Diptera: Oestroidea) are Not a Monophyletic Group.

To investigate the monophyly and phylogenetic relationships of the Calliphoridae (blowflies), 23 terminal monophyletic taxa within the Oestroidea and two outgroup taxa (Muscidae and Anthomyiidae) were scored for 45 adult and larval characters and subjected to analyses using parsimony. Search for trees of maximum total fit (using Pee-Wee) gave nine different trees for the possible values of the concavity constant, whereas search for minimum length trees under equal weights (using NONA and PAUP) gave two, different, trees. The preferred trees are those obtained from the maximum-fit searches since they are derived from a method that lowers the weight of characters showing within-terminal as well as within-tree homoplasy.
