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.

Sixty years ago, Willi Hennig last catalogued the Anthomyiidae, Fanniidae and Muscidae fauna of the Juan Fernández Archipelago. This archipelago, composed of three main volcanic islands (Robinson Crusoe, Alejandro Selkirk and Santa Clara), has many endemic species. We describe Fannia hennigi sp. n. from the Robinson Crusoe Island, and record 11 species in 10 genera of Anthomyiidae, Fanniidae and Muscidae. A key to the identification of all species found in Juan Fernández Archipelago and a table with all species found in the Archipelago are presented, including four new records from Robinson Crusoe Island: Delia platura (Meigen, 1826); Fannia hennigi sp. n.; Lispoides insularis Hennig, 1957 and Schoenomyzina emdeni Hennig, 1955.

The Fannia carbonaria-subgroup belongs to the Fannia carbonaria-group Chillcott, 1961. The world fauna of this subgroup is reviewed, the diagnostic features of the subgroup are redefined, and a key to the males of the known species is given. Two new species from China are described: F. dorsovittata Wang sp. nov. and F. subfuscitibia Wang sp. nov.. To facilitate comparisons of the species, Fannia corvina (Verrall), Fannia imperatoria Nishida and Fannia xiaoi Fan are redescribed. Geographic distributions of the species of the subgroup are updated. The systematic position and distribution patterns of the F. carbonaria-subgroup are discussed.

The aim of this study is to describe Fannia puxcu sp. n., a new species of the genus Fannia Robineau-Desvoidy (Diptera: Fanniidae) that was collected in the Villavicencio provincial reserve in Mendoza, Argentina, and to present an updated key to the 27 species of Fannia Robineau-Desvoidy (Diptera: Fanniidae) of Southern South America. The male of F. puxcu sp. n. is described, and illustrations provided as well as distributional records and a discussion of its possible phylogenetic affinities. Fil: Dominguez, Martha Cecilia.

The Family Fanniidae in Beijing, China, consisting of seventeen species, is reviewed. Seven species represent new records from this region, including two species that are newly recorded from mainland China. One new species (Fannia papei sp. nov.) collected from the mountainous regions of Beijing is described. Three species (F. carbonaria, F. dupla and F. hirticeps) are re-described to provide updated characters and extensive variation information, and a key to identify the known males from Beijing is also given.

A new species, Fannia caucasica sp. nov., is described from localities in Georgia and Armenia between 1600 and 2200 m. In addition, previous literature on the genus Fannia Robineau-Desvoidy, 1830 in the Caucasus Mountains is reviewed, and records are given for 15 species from Armenia and Georgia, of which nine are new records for Armenia and seven are new records for Georgia.

The type material of species of Calyptratae Diptera belonging to Anthomyiidae, Calliphoridae, Fanniidae, Muscidae, Sarcophagidae, and Tachinidae, housed in the collections of non-traditional institutions in Argentina were examined. These collections were included in the recently created “Sistema Nacional de Datos Biologicos” (National Biological Data System). We examined four collections: “Administracion Nacional de Laboratorios e Institutos de Salud ‘Dr. Carlos G. Malbran’” (ANLIS), “Instituto Nacional de Tecnologia Agropecuaria, Castelar, Buenos Aires” (INTA), “Instituto Argentino de Investigaciones de las Zonas Aridas” (IADIZA); and “Fundacion Felix de Azara” (CFA). Comparison of the original descriptions of these species with the label information revealed the existence of 24 holotypes, 5 lectotypes, 11 syntypes, and 441 paratypes/paralectotypes. Complete information is given for each type, including reference to the original description, label data, and preservation condition.

The aim of this study is to describe Fannia puxcu sp. n., a new species of the genus Fannia Robineau-Desvoidy (Diptera: Fanniidae) that was collected in the Villavicencio Provincial Reserve in Mendoza, Argentina, and to present an updated key to the 27 species of Fannia Robineau-Desvoidy (Diptera: Fanniidae) of Southern South America. The male of F. puxcu sp. n. is described, and illustrations provided as well as distributional records and a discussion of its possible phylogenetic affinities.

Fannia Robineau-Desvoidy is a genus of calyptrate Diptera that comprises 89 Neotropical species, of which only 23 occur in Colombia. Based on male characters (including terminalia), two new species from the Department of Antioquia ( Fannia colazorrensis sp. nov. and Fannia laclara sp. nov.) are described. Illustrations of the male are presented.

The Fannia lepida-group is reviewed. Fannia immutica Collin is recorded for the first time in China. A key to males of the four known species is provided. Fannia lepida (Wiedemann), F. grahami Chillcott, and F. immutica Collin are redescribed and the male terminalia illustrated. Fannia grahami remained unrecorded since its 1961 original description.

The Holarctic genus Piezura Rondani (Diptera, Fanniidae) is reviewed. Phylogenetic relationships among the species in this group, as well as the biogeography of these species, are discussed on the basis of a cladistic analysis. Piezura graminicola shanxiensis Xue, Wang and Wu, 1998 is redescribed and elevated to species rank based on comparison of its morphology and phylogenetic relationships. Syllegopterula flava Hsue, 1983 and its replacement name Thricops flavidus Xue, 1998 are treated as junior synonyms of Piezura graminicola (Zetterstedt, 1846).

The Fannia hirticeps-group, an endemic Holarctic group, is reviewed to include Fannia xuei sp. nov. from China (Guizhou). The F. hirticeps-group is redefined and a key is given to the twelve known world species. Fannia limbata (Tiensuu) is transferred to this group, and new data on distributions are reported for the included species.

The Fannia serena-subgroup belongs to the Fannia serena-group Chillcott. This paper outlines early studies on the F. serena-subgroup and F. serena-group. The F. serena-group is redefined and a key is given to its four subgroups: serena-subgroup Chillcott, rondanii-subgroup Chillcott, sociella- subgroup Chillcott, and mollissima-subgroup Pont. Two new species, Fannia diploura Wang, Xue & Zhang sp. nov. and Fannia setifemorata Wang, Xue & Zhang sp. nov., are described from China. The eleven known Chinese species of the F. serena-subgroup are reviewed and keyed.

The world fauna of the genus Piezura Rondani is revised in order to resolve a series of long standing taxonomic errors. All species are redescribed, and species concepts and distribution ranges of most species have been modified. The genitalia of all species are illustrated and keys to each sex are provided. The female of P. nearctica Chillcott is described for the first time. Piezura pardalina shanxiensis Wang et al, 1992 is treated as an unavailable name, and P. pardalina shanxiensis Xue et al, 1999 is accepted as the valid name for this taxon.

The Fanniidae (Diptera) of the Neotropical Region are catalogued. Two genera and 75 valid species are listed, with references to original descriptions, location of types, geographic distribution, and subsequent taxonomic and applied literature. Mesazelia trichopoda Blanchard, 1942 is a new synonym of Anthomyia pusio Wiedemann, 1830.
