Description of three new species of Dexosarcophaga (Diptera, Sarcophagidae) from Brazil with new information on synonyms and filling gaps in species distribution.

Three new species of DexosarcophagaTownsend, 1917 are described based on male specimens collected in Brazil, Dexosarcophaga sinoisp. nov., Dexosarcophaga autisferasp. nov., and Dexosarcophaga clavissp. nov. Male morphology is represented by photographs and detailed illustrations of terminalia. Dexosarcophaga carvalhoi (Lopes, 1980), Dexosarcophaga globulosaLopes, 1946, Dexosarcophaga limitata (Lopes, 1975), Dexosarcophaga paulistana (Lopes, 1982b), and Dexosarcophaga petraSantos, Pape and Mello-Patiu 2022 are recorded for the first time in Argentina. Also, Dexosarcophaga lenkoiLopes, 1968, Dexosarcophaga montana (Lopes, 1975), and Dexosarcophaga transitaTownsend, 1917 have their distribution expanded with new records. Dexosarcophaga transita is considered a senior synonym of Dexosarcophaga chaetosaBlanchard, 1939syn. nov., Dexosarcophaga itaquaDodge, 1966syn. nov., and Dexosarcophaga lopesiDodge, 1968syn. nov. With the addition of the new species and the new synonymies proposed, Dexosarcophaga now contains 58 species, of which 10 are recorded in Argentina and 35 in Brazil.

Flesh Flies (Diptera: Sarcophagidae) of Forensic Importance Collected From Pig Carcasses in the Cerrado of Northeastern Brazil.

Sarcophagidae is a family of true flies frequently found colonizing carcasses and corpses as adults and/or larvae, therefore, they are of great forensic value in the medico-legal field. Thus, this study aims to inventory the sarcophagids species and describe their succession process in the decomposition of swine carcasses in the Cerrado (savanna-like vegetation), Brazilian Northeastern region. A total of 10,819 specimens were collected, belonging to 45 sarcophagid species. Of this total, one species was recently described (Helicobia neuzalmeidae Silva, Brasil, De-Souza & Carvalho-Filho), two [Blaesoxipha (Acanthodotheca) denieri (Blanchard) and Dexosarcophaga pusilla Lopes] are new records for the Cerrado biome, five [Argoravinia (Argoravinia) catiae Carvalho Filho & Esposito, B. (A.) denieri, Nephochaetopteryx orbitalis (Curran & Walley), Peckia (Sarcodexia) tridentata (Hall) and Tricharaea (Sarcophagula) ramirezi (Lopes)] are new records for the Northeast region and eight are new records for the state of Maranhão. The species A. (A.) catiae, Blaesoxipha (Gigantotheca) stallengi (Lahille), D. pusilla, H. neuzalmeidae, Lipoptilocnema misella Lopes, Oxysarcodexia bakeri (Aldrich) and Retrocitomyia retrocita (Hall) were collected for the first time in pig carcasses. Peckia (Sarcodexia) lambens (Wiedemann) and Oxysarcodexia thornax (Walker) were the most abundant species. In both collection seasons, five species were carcasses pioneers at an early stage. The majority of species (42 spp.) were collected during the dry season, primarily during the black putrefaction (39 spp.) and butyric fermentation (30 spp.) stages. The greatest number specimens (n = 6,484) were recorded during the rainy season, at the butyric fermentation (n = 2,517) and black putrefaction (n = 2,080).

Flesh Flies (Diptera: Sarcophagidae) From the Brazilian Amazonian Savannas, a Poorly Sampled and Threatened Environment.

The Amazonian region is composed by many kinds of environments, including the Amazonian savannas, which comprise about 5% of the Amazon biome in Brazil. The biota of Amazonian savannas is poorly known, especially for insects. In this study, we performed a faunistic inventory of flesh flies (Diptera: Sarcophagidae) of four Brazilian Amazon savannas, where we recorded two subfamilies, 16 genera, and 40 species, two of which are described as new to science: Lepidodexia (Notochaeta) helenae sp. nov. and Lipoptilocnema augustoi sp. nov. Oxysarcodexia graminifoliaSouza, Pape & Thyssen, 2020 is recorded for the first time for Brazil. Dexosarcophaga paulistanaLopes (1982), Helicobia biplagiataDodge, 1966, Helicobia cearensisTibana, 1976, Oxysarcodexia simplicoides (Lopes, 1933), and Oxyvinia excisa (Lopes, 1950) are newly recorded for the Brazilian Amazon. Oxysarcodexia nitidaSoares & Mello-Patiu, 2010 is a new record for the state of Pará. The species D. paulistana is redescribed, and photographs and detailed illustrations of male terminalia are provided.

Revision of Nephochaetopteryx Townsend, 1934 (Diptera: Sarcophagidae).

Nephochaetopteryx Townsend, 1934 is a genus of flesh flies predominantly Neotropical in distribution, which comprises small species (4.0-7.3 mm) characterized mainly by vein R1 fully setulose dorsally and wing usually fumose between apical part of vein R2+3 and vein C. The taxonomic revision of the genus resulted in 39 valid species, of which 12 are new to science: N. boruca sp. nov., N. canga sp. nov., N. coendu sp. nov., N. cuzco sp. nov., N. equatoriana sp. nov., N. inca sp. nov., N. lamasi sp. nov., N. matinta sp. nov., N. psittacocercus sp. nov., N. sofiae sp. nov., N. similis sp. nov. and N. tembe sp. nov. Nephochaetopteryx shannoni Dodge, 1968 is a junior synonym of N. flavipalpis Lopes, 1936, syn. nov. and N. linharensis Tibana Santos 1997 is a junior synonym of N. pallidifacies Lopes 1975, syn. nov. A key to the males of all valid species is given, as well as detailed illustrations of the male terminalia.

New carrion-visiting flesh flies (Diptera: Sarcophagidae) from tropical dry forests of Colombia and their phylogenetic affinities.

Many flesh flies of the subfamily Sarcophaginae are very competitive carrion visitors and breeders, and several are synanthropic species of medical and forensic importance. The knowledge of these taxa is still limited, which is more noticeable in sub-sampled ecosystems such as the tropical dry forests of Colombia. Four new species, Blaesoxipha (Gigantotheca) wajiira sp. nov., Lepidodexia deborarangoa sp. nov., Oxysarcodexia luriza sp. nov. and Udamopyga iku sp. nov., are described from tropical dry forests in the Colombian departments of Atlántico, Bolívar, Cesar and La Guajira, all collected using Van Someren-Rydon traps baited separately with fermented fruit, decomposing fish and human feces. The species B. (G.) wajiira sp. nov. is probably synanthropic, while the remaining three new species avoid habitats in and around built-up areas. A phylogenetic parsimony analysis based on 222 morphological characters across 121 taxa of flesh flies recovers each new species nested within their respective genus. The subgeneric affiliation of L. deborarangoa sp. nov. within the large and diverse genus Lepidodexia (sensu lato) is inconclusive, and potential issues of relying solely on external morphological characters for generic and subgeneric classifications are highlighted. The species Lepidodexia (Notochaeta) woodi (Lopes), Oxyvinia wicharti (Lopes) and Sarcofahrtiopsis spinetta Mulieri & Dufek are new records for Colombia. COI sequence data are provided for U. iku sp. nov., L. (N.) woodi and O. wicharti.

Description of Two New Species of Dexosarcophaga (Diptera: Sarcophagidae) From the Coastal Environments of the Brazilian Amazon.

Two new species of Dexosarcophaga Townsend (Diptera: Sarcophagidae) are described, both from the coastal zone of the Brazilian Amazon: Dexosarcophaga salgada sp. nov. and Dexosarcophaga klycyae sp. nov.

Oxysarcodexia Townsend, 1917 (Diptera: Sarcophagidae)-a centennial conspectus.

A taxonomic conspectus is presented for the genus Oxysarcodexia Townsend, 1917, which is one of the most species-rich genera of New World flesh flies. It has its center of diversity in the Neotropical Region, with some species reaching into the Nearctic and a few species introduced to the Australasian and Oceanian Regions. Species within this genus are primarily dung-breeders, but some species have also been bred from vertebrate carcasses. Oxysarcodexia is defined and diagnosed, and a diagnosis, distributional data and known biological data are provided for each species together with figures of the habitus and male terminalia. Oxysarcodexia currently comprises 91 valid species, including six species newly described herein: O. alectoris sp. n. (French Guiana), O. angulosa sp. n. (Costa Rica), O. ariozanoi sp. n. (Brazil), O. graminifolia sp. n. (Colombia and Ecuador), O. maiae sp. n. (Ecuador), and O. rimata sp. n. (Ecuador). Two nominal species based on a male holotype, Oxysarcodexia bomplandi (Hall, 1937) and O subsericans (Walker, 1858), were left unidentified pending examination of their terminalia. Four nominal species, O. aureiceps (Macquart, 1855), O. dorisae Dodge, 1965, O. flavifrons (Macquart, 1846) and O. neivae Mattos, 1919, all described solely based on females, are considered of uncertain status pending a comprehensive study of females of this genus. Asioboettcheria Verves, 2001 is proposed as a junior synonym of Oxysarcodexia Townsend, 1917, syn. n., Oxysarcodexia cuernavaca Dodge, 1966 is proposed as a junior synonym of O. ventricosa (Wulp, 1895), syn. n., and Stackelbergeola papei Nandi, 1994 is proposed as a junior synonym of O. thornax (Walker, 1849), syn. n. A lectotype is designated for Sarcophaga varia Walker, 1836 [= O. varia (Walker, 1836)]. The newly-described O. ariozanoi and O. maiae are included in the "xon group" (former "Xarcophaga group"). New country-level distributional records are provided for O. adunca Lopes, 1975 (Ecuador), O. berlai Lopes, 1975 (Peru), O. cocais Carvalho-Filho, Sousa Esposito, 2017 (Argentina), O. insolita Lopes, 1946 (Ecuador), O. jamesi Dodge, 1968 (Costa Rica), O. marina (Hall, 1938) (Brazil), O. nitida Soares Mello-Patiu, 2010 (Ecuador), O. notata Soares Mello-Patiu, 2010 (Brazil and Ecuador), and O. terminalis (Wiedemann, 1830) (Paraguay).

Flesh flies (Diptera: Sarcophagidae) from a white-sand habitat in the Brazilian Amazon, with the description of four new species.

The white-sand enclaves in the Amazon Basin are small areas scattered through the tropical forest, with sandy and nutrient-poor soils and an unusual vegetation type. The insect fauna of this ecosystem is poorly known, especially in the eastern Amazon. The flesh fly fauna of an area of open herbaceous white-sand vegetation known as "Campo Redondo" in the municipality of Cametá, state of Pará, was surveyed, resulting in the discovery of 43 species in 11 genera representing the subfamilies Sarcophaginae and Miltogramminae. Four new species are described: Dexosarcophaga (Dexosarcophaga) campina sp. nov., Helicobia cametaensis sp. nov., Helicobia domquixote sp. nov., and Metopia fofo sp. nov. Lepidodexia (Lepidodexia) grisea Lopes and Lepidodexia (Notochaeta) setifrons (Lopes) are newly recorded from Brazil. Dexosarcophaga (Bezzisca) ampullula (Engel), D. (Dexosarcophaga) transita Townsend and Titanogrypa (Cucullomyia) larvicida (Lopes) are newly recorded from the Brazilian Amazon.

Five new species of the flesh fly genus Boettcheria (Diptera: Sarcophagidae).

Five new Neotropical species of the flesh fly genus Boettcheria Parker, 1914 are described: B. brachion sp. nov. (Venezuela), B. dikros sp. nov. (Costa Rica), B. hirta sp. nov. (Costa Rica), B. tridens sp. nov. (Venezuela), and B. ulo sp. nov. (Venezuela). The definition of the genus is briefly discussed.

The genus Peckia Robineau-Desvoidy (Diptera: Sarcophagidae) in the Brazilian Amazon: a new species, new records, descriptions of female terminalia and key to species.

Flesh flies of the genus Peckia Robineau-Desvoidy, 1830 were studied from the Brazilian Amazon region. The male terminalia of all species are illustrated. The female terminalia are described and illustrated for all species for which the female is known. The female terminalia of six species are described for the first time; those of seven species are redescribed and documented through new illustrations. A new species of the subgenus Pattonella Enderlein, 1928, Peckia (Pattonella) juruti sp. nov., is described. It is similar to Peckia (Pattonella) smarti (Lopes, 1941) in the shape of the cercus and distiphallus, but differs in the shape of the gonites, juxta and capitis. Peckia (Peckia) hillifera (Aldrich, 1916) is recorded from Brazil for the first time; Peckia (Euboettcheria) florencioi (Prado Fonseca, 1932) is newly reported for the Brazilian Amazon. A key to the 21 species of Peckia so far recorded from the Brazilian Amazon is provided, allowing the identification of both sexes where known. The females of only five of these species remain unknown.

A new species and new records of Oxysarcodexia Townsend (Diptera: Sarcophagidae) from Brazil

Abstract Oxysarcodexia cocais sp. nov. from Brazil is described and illustrated based on male specimens collected in a babassu palm forest in the state of Maranhão. The remarkable elongated surstylus (as long as cercus) and U-shaped male sternite 5 distinguishes the new species from other species in the genus. In addition, Oxysarcodexia nitidaSoares & Mello-Patiu, 2010 is recorded for the first time from Brazil, and Oxysarcodexia adunca Lopes, 1975 is a new record from the Brazilian Amazon.

Photographs and SEM images are provided to aid in the identification of the species.

Flesh flies (Diptera: Sarcophagidae: Sarcophaginae) from the Colombian Guajira biogeographic province, an approach to their ecology and distribution

Sarcophaginae is the most diverse subfamily of Sarcophagidae with 51 genera and more than 1,800 species and it is widely distributed in the Neotropical Region. Sarcophaginae flies of forest, rural, and urban habitats of the seven departments comprising the Colombian Guajira biogeographic province were surveyed. Van Someren Rydon traps baited with fermented fruit, decomposing fish, and human feces were active for 72 hours with samples collected every 12 hours (day/night) between 2010 and 2014. A total of 14,223 sarcophagines (78% females and 22% males) were collected, which belong to 28 species of nine genera. Oxyvinia excisa (Lopes, 1950) is a new record for Colombia. The richest genera were Oxysarcodexia Townsend, 1917 and Peckia Robineau-Desvoidy, 1830, with eleven and nine species, respectively. Some of the species with the highest affinity to urban habitats were Oxysarcodexia bakeri (Aldrich, 1916), Oxysarcodexia aurata (Macquart, 1851), and Oxysarcodexia timida (Aldrich, 1916); to rural habitats were Oxysarcodexia diana (Lopes, 1933), Ravinia columbiana (Lopes, 1962), and Ravinia effrenata (Walker, 1861); and to forest habitats were Helicobia rapax (Walker, 1849), Oxysarcodexia avuncula (Lopes, 1933), and Oxysarcodexia major Lopes, 1946. We also discuss diet, habitat, and activity periods of the species. Species composition of Sarcophaginae in the Guajira province was very homogenous across the habitats, with the forest as the richest habitat. Scavenger habits of Sarcophaginae are confirmed, as well as their strong association with anthropic environments.

On the taxonomic status of Nephochaetopteryx calida (Wiedemann) (Diptera, Sarcophagidae)

On the taxonomic status of Nephochaetopteryx calida (Wiedemann) (Diptera, Sarcophagidae). Based on analysis of the holotype of Nephochaetopteryx calida (Wiedemann) it was concluded that this species does not belong to Nephochaetopteryx. The holotype is a female partly damaged and it was not possible to place it in one of Sarcophaginae genera, remaining as Sarcophaga calida Wiedemann, 1830, incertae sedis.

Synanthropic trends in urban andextraurban taxocenoses of Sarcophaginae (Diptera) in three central european cities

An attempt has been made to characterize the synanthropic trends in Sarcophaginae of three Central European cities, viz. Brno, Bratislava and Budapest. The polar ordination of both sarcophagine taxa and of their taxocenoses revealed clear-cut trends towards culturophily and synanthropy in the male preconnubial aggregations of Sarchophaginae evidencing that this group of high Diptera represent an excellent model for the study of this phenomenon.
