The Diptera fauna of the Galápagos Archipelago is updated and an annotated checklist is presented. Currently 50 families, 207 genera, and a minimum of 324 species are recorded from the islands. Approximately 107 species are considered to have arrived on the Galápagos Islands through human introductions, an estimated 101 species are considered endemic, 42 species have naturally colonized the islands from mainland Americas, 21 species are either introduced or arrived naturally and 53 species remain unidentified. The following new combination is proposed: Chrysanthrax primitivus (Walker) is moved to Hemipenthes Loew as H. primitivus (Walker) comb. nov. All references to the Galápagos taxonomic literature are included, known island species distributions listed and general remarks on the biology of many species are provided.

Fannia Robineau-Desvoidy is found in all biogeographic regions. The genus contains approximately 360 known species, 18 of which have been recorded from Mexico. Herein, we describe six new species in the Fannia pretiosa-group, redescribe Fannia gilvitarsis Chillcott, and provide diagnosis, habitus images, drawings of the male terminalia, and an identification key for all species of the group that occur in Mexico. All Fannia pretiosa-group species from Mexico share a similar morphology of the mid tibia, hind femur, and male terminalia.

canicularis (Linnaeus) Musca canicularis Linnaeus, 1761: 454. Homalomyia canicularis: Coquillett 1901a: 375 [records]. Fannia canicularis: Curran 1932: 359 [record]; Linsley & Usinger 1966: 171 [checklist]; Pont 1972: 3 [catalogue]; Peck 1996: 122 [mode of introduction]; Peck et al, 1998: 228 [introduced species]; Carvalho et al. 2003: 9 [catalogue]. Distribution. Introduced. Cosmopolitan; Galápagos [doubtful record]: Isabela. Remarks. Fannia canicularis is of temperate climates, and it is likely that if it was introduced in the Neotropics from the ships of early explorers, it would not become established. As such, this species is classified as a doubtful record. Supporting this idea, one of the females originally identified by Coquillett was found (in CAS) and tentatively determined as F. pusio (A.C.

Diptera is one of the most species-diverse insect orders. The paper presents data on the biodiversity of Diptera from 9 families (Tipulidae, Limoniidae, Pediciidae, Mycetophilidae, Keroplatidae, Ptychopteridae, Muscidae, Fanniidae, Sciomyzidae) inhabiting 14 regions within the Volga upland and Oka-Don lowland. The most studied fauna is in the Republic of Mordovia (399 species). The fauna of these families is least known from the Republic of Tatarstan, Lipetsk Region, Nizhny Novgorod Region, and Vladimir Region (9, 19, 20, and 21 species, respectively). A total of 545 species are known from 9 families of Diptera in the large macroregion. The largest number of species includes the families Muscidae (190) and Limoniidae (102). The biodiversity is least known in Ptychopteridae (4 species), Pediciidae (6 species) and Keroplatidae (10 species)., Diptera – это один из наиболее разнообразных по числу видов отряд среди насекомых. В статье представлены сведения о биоразнообразии Diptera из 9 семейств (Tipulidae, Limoniidae, Pediciidae, Mycetophilidae, Keroplatidae, Ptychopteridae, Muscidae, Fanniidae, Sciomyzidae), обитающих на территории 14 регионов, находящихся в пределах Приволжской возвышенности и Окско-Донской низменности. Наиболее изученная и разнообразная фауна в Республике Мордовия (399 видов). Наименее известна фауна этих семейств из Республики Татарстан, Липецкой области, Нижегородской области и Владимирской области (соответственно, 9, 19, 20 и 21 вид). В общей сложности на территории большого макрорегиона из 9 семейств Diptera известно 545 вида. Наибольшее число видов включают семейства Muscidae (191) и Limoniidae (102). Наименее известно биоразнообразие Ptychopteridae (4 вида), Pediciidae (6 видов) и Keroplatidae (10 видов).

The Fannidae includes over 400 described species, mainly known from the Holarctic Region. The number of species in the Oriental Region are underestimated. The Fannia fuscinata-group was established by Wang et al. in 2011, consisting of nine species at present. A new species of the genus Fannia (Diptera, Fanniidae) is described from Yunnan, part of the Oriental Region in China, namely Fannia menglaensis sp. nov. The detailed description, photographs and drawings of adults and male terminalia of F. menglaensis sp. nov. are provided. All specimens are preserved in the Museum of Beijing Forestry University.

The present study examines whether the chaetotaxy of the costal vein in the calyptrate families Fanniidae and Muscidae deserves more attention in phylogenetic and taxonomic contexts. An overview of the macrotrichia and their arrangement on wing vein C is given. Special attention is given to the presence/absence of ventral and dorsal setulae on the costal sectors CS1‒3. This is described as one variable character (A) with nine states (A0‒A8). Specimens of both sexes (when possible) of each species belonging to 4 of a total of 5 fanniid genera and 115 of a total of 179 muscid genus-group taxa were examined and scored for character A. It was found that the presumed ancestral state of character A differs between the two families. It is further shown that the main transformational trend in character A in Muscidae has been bi-directional, leading either to the loss of ventral setulae or the gain of dorsal setulae. The utility of character A in the Fanniidae and Muscidae is many-sided and involves taxa ranging from species to family. It is concluded that character A and other aspects of costal chaetotaxy deserve more attention in morphology-based studies of calyptrate flies.

Family Fanniidae Schnabl & Dziedzicki, 1911 A distinctive, modest-sized family known for ca 400 extant species currently classified in five genera (Table 1). Species belonging to four fanniid genera have presently been scored for the distribution of setulae dorsally and ventrally (character A) on vein C (Table 1) in agreement with the states described above. • Euryomma Stein, 1899, Fannia Robineau-Desvoidy, 1830 (Fig. 2A–C), Piezura Rondani, 1844 (Fig. 2D) All examined species are without ventral setulae behind the lower anterior row of alternating spinules and setulae of vein C (state A0): Euryomma americanum Chillcott, 1961, E. muisca Grisales, Wolff & de Carvalho, 2012, E. peregrinum (Meigen, 1826), Fannia (50+ spp) incl. F. fuscula (Fallén, 1825) (Fig. 2A–C), Piezura graminicola (Zetterstedt, 1846) and P. pardalina Rondani, 1866 (Fig. 2D). In Piezura graminicola and P. pardalina (Fig. 2D) rows of ventral and dorsal costal setulae on CS1 represent setulae displaced from the anterior spinule-setula rows; these accordingly consist of spinules only. • Australofannia Pont, 1977 (Figs 3A–D, 4A–B) This genus consists of Australofannia spiniclunis Pont, 1977 and one undescribed species, both endemic to Australia (Pont 1977). Examination of A. spiniclunis revealed a costal chaetotaxy deviating substantially from the usual fanniid pattern. Both sexes (Figs 3–4) have vein C extensively setulose both ventrally and dorsally (state A8). Further, extensive weakening of the costal spinules has taken place: the lower anterior costal row is wholly setulose in both sexes, whereas the upper anterior row has retained the usual spinule-setula pattern in the female (Figs 3A–C, 4A), but with only a few spinules distally on CS 1 in the male sex (Fig. 4B)., Published as part of Michelsen, Verner, 2022, Costal vein chaetotaxy, a neglected character source in Fanniidae and Muscidae (Diptera: Calyptratae), pp. 94-134 in European Journal of Taxonomy 826 on pages 98-103, DOI: 10.5852/ejt.2022.826.1839, http://zenodo.org/record/6784127, {"references":["Chillcott J.

The Fannidae includes over 400 described species mainly known from the Holarctic Region. Species in Oriental Region is under estimate. A new species of the genus Fannia (Diptera, Fanniidae) is described from Yunnan, Oriental part of China, namely Fannia menglaensis sp. nov. The detailed description and morphological photographs of F. menglaensis are provided. All specimens are preserved in the Museum of Beijing Forestry University.

Fanniidae This family, formerly considered a subfamily of Muscidae (Sabrosky 1999, Marshall 2012), contains more than 350 species (Evenhuis & Pape 2020). Rondani (1866a, 1868b, 1871a, 1877c) described 13 Palaearctic and one South American nominal species in his “ Stirps Anthomyinae ”. The family Fanniidae was proposed by Schnabl & Dziedzicki (1911). Three of these are currently considered as valid, one as a senior (but invalid) synonym, and ten as junior synonyms (Pont 1972, 1986a, 2002, Gorodkov et al. 1995, Carvalho et al. 2003). Hennig (1961: 226) examined the type material in the MZUF without publishing any lectotype designation. Rondani (1866a) proposed one name in synonymy and was not made available by use as a valid species before 1961; Costa (1866) listed one unpublished name (nomen nudum) of Rondani. Except for the type material of Homalomyia carbonaria, which is presumed lost, and for the syntypes of five species in the OUMNH and three in the MSNC, the type material has been recovered for all nominal species and is in the MZUF., Published as part of Sforzi, Alessandra & Sommaggio, Daniele, 2021, Catalog of the Diptera types described by Camillo Rondani, pp. 1-438 in Zootaxa 4989 (1) on page 112, DOI: 10.11646/zootaxa.4989.1.1, http://zenodo.org/record/4980621, {"references":["Sabrosky, C.

The Fannia serena species group (Diptera: Fanniidae) ismainly distributed in the Holarctic region and comprises four subgroups with a total of 32 species. Three new species of the Fannia serena-subgroup, Fannia aureomarginata Wang et Cheng, sp. n., F. suberemna Wang, sp. n. and F. wui Wang, sp. n., are described from China. An identification key to all known species of the Fannia serena-subgroup is also provided.

This paper documents the presence of 20 species of Fanniidae in Finland. Fannia alpina Pont, 1970 and F. slovaca Gregor & Rozkošný, 2005 are new to North Europe. Fannia barbata (Stein, 1892), F. lineata (Stein, 1892) and F. nigra Malloch, 1910 are removed from the Finnish checklist. The female of Fannia stigi Rognes, 1982 is described from a Finnish specimen caught together with a male. The total number of fanniid flies known from Finland is now 61.

During a study of arthropod succession on pig carrion in Portugal eleven species of Fannia Robineau-Desvoidy (Diptera: Fanniidae) were collected, of which F. aequilineata Ringdahl, F. armata (Meigen) and F. pusio (Wiedemann) are new records for Portugal, F. consepcta Rudzinski and F. lineata (Stein) are newly recorded for the whole Iberian Peninsula and F. tunisiae Chillcott is for the first time reported from the continental Europe. Additional information on the occurrence of F. conspecta in Czech Republic, Denmark, Greece, and Southern Russia are presented. The number of Fanniidae distributed throughout the Iberian Peninsula raises from 35 to 38 and the number of species reported from Portugal raises from 11 to 17.

A new species of the genusFannia(Diptera, Fanniidae) is described from Yunnan, China, namelyFanniabaihualingensissp. nov.The male habitus as well as terminalia are documented with focus-stacked photographs. A detailed comparison of new species with related species is provided.

Techniques for the survey of necrophagous dipterans are frequently designed for adult flies and often neglect forensically important information, such as the postfeeding larval dispersal following carcass colonization. In this study, we propose and test a novel trap design for the collection of dipteran larvae at the postfeeding stage. The Trap for Dispersing Larvae (TDL) consists of two semiindependent parts: 1) a 2-liter PET bottle, containing the attractant (carcass); and 2) a plastic box, which selectively captures postfeeding dispersing larvae. Based on a field test in a dry forest fragment in Brazil, the TDL trap captured ca. 1,500 larvae of 13 species of Calliphoridae, Muscidae, Fanniidae, and Sarcophagidae. The species richness of dispersing larvae recorded in our study was ca. 60% of that previously recorded in this area. As the TDL trap can assess larval dispersal without interfering with carcass decomposition, we demonstrate that it can be used to assess temporal variation in the dynamics of colonization. In the present study, most larval dispersal occurred at 5-d postexposure, but the traps remained efficient until 7 d, by which time rat carcasses had skeletonized. We conclude that the TDL trap captures the dispersing dipteran larvae with little interference in carcass decomposition processes. The trap also provides a representative sample of species and is simple to use and of low cost.

Entomological material may be used to estimate the time since death occurred (minimum post-mortem interval, mPMI) in forensically obscure cases. The method commonly used to calculate mPMI is the application of a thermal summation model. Little is known about the thermal requirements of Fanniidae. To fill this gap, the influence of temperature on the development time of Fannia canicularis (Linnaeus), a cosmopolitan species with the potential to be used in forensic entomology, was studied. An experiment was performed under nine ambient temperatures. The thermal summation constants (k) and developmental zeros (Tmin) of this species were calculated for six developmental events: hatching, first ecdysis, second ecdysis, wandering, pupariation, and eclosion. Data were primarily analysed with two linear models, and then, since the relationship between temperature and development rate is curvilinear close to the lower and higher developmental thresholds, the relationship was also modelled using three nonlinear models. A fourth nonlinear model was also used to estimate the intrinsic optimum temperature of F. canicularis, at which the population size is maximal and the mortality is the lowest. At 33 °C, larvae did not hatch from eggs, and thus changes in larval body length were analysed at the eight remaining temperatures. Fannia canicularis development from egg to eclosion required a mean ± SE of 481.73 ± 9.89 degree-days above a lower threshold temperature of 4.64 ± 0.19 °C. At the lowest experimental temperature tested, 10 °C, F. canicularis successfully completed all developmental events, although ca. 30% of wandering larvae proceeded to the inactive stage instead of pupariation. Results obtained from nonlinear models were not satisfactory and did not allow us to consider them as reliable from a biological point of view.

During inventory studies of Diptera and experiments on arthropod succession on decomposing pig carrion in Poland, we obtained several interesting Fanniidae species. Among the examined material, we identified Fannia collini d'Assis-Fonseca, Fannia hirticeps (Stein), Fannia nigra Malloch and Fannia ornata (Meigen), which are here reported as new for Poland. We also found Fannia pauliPont, Fannia speciosa (Villeneuve) and Fannia umbrosa (Stein), which have already been reported from Poland, but considered rare or not common in the area of their distribution. The geographic distribution of some fanniids may be considered doubtful because of contradictory information found in the available literature. Thus, based on the present records, we confirm the occurrence of Fannia aequilineata Ringdahl and Fannia latipalpis (Stein) in the Polish fauna.

Resumo Esta e a primeira vez que se registra a veiculacao de ovos de Dermatobia hominis (L.) (Insecta, Diptera, Oestridae) por Fannia punctipennis (Albuquerque) (para o Sudeste do Brasil) e por Fannia canicularis (L.) (para a America do Sul) (Insecta, Diptera, Fanniidae), respectivamente. Phoresy record of Dermatobia hominis (L.) (Diptera, Oestridae) eggs by Fannia canicularis (L.) and Fannia punctipennis (Albuquerque)(Diptera, Fanniidae) in Sao Paulo, Brazil Abstract This is the first record of Dermatobia hominis (L.) (Insecta, Diptera, Oestridae) eggs carried by Fannia punctipennis (Albuquerque) (for Southeast Brazil) and by Fannia canicularis (L.) (for South America) (Insecta, Diptera, Fanniidae), respectively.

Necrophagous flies are of great importance for human and animal health. In places where their development occurs, parasitoids can be used as a tool to control these dipterans. In Brazil, the fauna of these parasitoids has been investigated in some regions. However, in Rio Grande do Sul, it is known the occurrence of only one species. Thus, this study aimed to create the first list of parasitoids in flies of medical and veterinary importance in Southern Brazil. Collections took place in the municipality of Pelotas (31º 42’ S; 52º 18’ W). Three replicates consisting of a 500 g bovine liver chunk placed in a tray were exposed to open air for 20 days. Then pupae were individualized and observed until their emergence. We identified 4,882 adult flies of Calliphoridae, Fanniidae, Muscidae, and Sarcophagidae. 4,040 parasitoids emerged, belonging to eight species, of which Nasonia vitripennis, Spalangia cameroni, Spalangia chontalensis, and Tachinephagus zealandicus are new records in Rio Grande do Sul state. Also, three undescribed species of the genus Aphaereta were collected. In spite of being the first attempt to inventory the fauna of hymenopteran parasitoids, this study may help in the development of management programs of these dipterans in the region. Resumo Moscas necrófagas possuem grande importância para a sanidade humana e animal. Onde estas se desenvolvem ocorrem parasitoides que podem ser utilizados como ferramentas para o controle desses dípteros. No Brasil, a fauna desses parasitoides vem sendo investigada em algumas regiões e no Rio Grande do Sul é conhecida a ocorrência de apenas uma espécie. Portanto, o objetivo deste estudo foi criar a primeira lista de espécies de parasitoides de moscas de importância médica e veterinária ocorrentes no extremo sul do Brasil. As coletas foram realizadas no município de Pelotas (31º 42’ S; 52º 18’ O). Foram montadas três réplicas de bandejas contendo, cada uma, 500 g de fígado bovino, expostas ao ar livre durante 20 dias. Na sequência, as pupas foram individualizadas e observadas até a emergência. Foram identificados 4.882 adultos pertencentes às famílias Calliphoridae, Fanniidae, Muscidae e Sarcophagidae. Emergiram 4.040 parasitoides, pertencentes a oito espécies, das quais Nasonia vitripennis, Spalangia cameroni, Spalangia chontalensis e Tachinephagus zealandicus são novas ocorrências para o Rio Grande do Sul. Foram coletadas três espécies ainda não descritas do gênero Aphaereta. Apesar de ainda ser um primeiro esforço de inventariar a fauna de himenópteros parasitoides, este estudo pode auxiliar no desenvolvimento de programas de manejos desses dípteros na região.
