Syrphidae is one of the most speciose families of true flies, with more than 6,100 described species and worldwide distribution. They are important for humans acting as crucial pollinators, biological control agents, decomposers, and bioindicators. One third of its diversity is found in the Neotropical Region, but the taxonomic knowledge for this region is incomplete. Thus, taxonomic revisions and species checklists of Syrphidae in the Neotropics are the highest priority for biodiversity studies. Therefore, we present the first checklist of Syrphidae for Ecuador based on literature records, and provide as well the original reference for the first time species citations for the country. A total of 201 species were recorded for Ecuador, with more than 600 records from 24 provinces and 237 localities. Tungurahua, Pastaza, and Galápagos were the best sampled provinces. Although the reported Ecuadorian syrphid fauna only comprises 11.2 % of the described Neotropical species, Ecuador has the third highest flower fly diversity density after Costa Rica and Suriname. These data indicate the high species diversity for this country in such small geographic area. © Diego Marín-Armijos et al.

A new interaction between insects and carnivorous plants is reported from Brazil. Larvae of the predatory flower fly Toxomerus basalis (Diptera: Syrphidae: Syrphinae) have been found scavenging on the sticky leaves of several carnivorous sundew species (Drosera, Droseraceae) in Minas Gerais and So Paulo states, SE Brazil. This syrphid apparently spends its whole larval stage feeding on prey trapped by Drosera leaves. The nature of this plant-animal relationship is discussed, as well as the Drosera species involved, and locations where T. basalis was observed. 180 years after the discovery of this flower fly species, its biology now has been revealed. This is (1) the first record of kleptoparasitism in the Syrphidae, (2) a new larval feeding mode for this family, and (3) the first report of a dipteran that shows a kleptoparasitic relationship with a carnivorous plant with adhesive flypaper traps. The first descriptions of the third instar larva and puparium of T. basalis based on Scanning Electron Microscope analysis are provided.

In order to study species of Eristalinae in Lara state, Venezuela, adults and preimaginal stages were sampled biweekly in Crespo, Iribarren, Jimenez, Moran and Palavecino municipalities. The sampling of adults was conducted using an entomological net, while larvae and pupae were collected on and in rotting cacti. A total of 1 070 specimens of Eristalinae grouped in 5 genera and 17 species were collected. Copestylum chalybescens, Copestylum fraudulentum, Copestylum villarica and Copestylum tamaulipanum were recorded from Venezuela for the first time. In addition, we provide first-time information about the preimaginal biology of Nausigaster flukei and Copestylum flaviventre feeding on Opuntia cladodes and columnar stems of Cereus respectively. Moreover, a new species to science of the genus Nausigaster was found, the larvae of which feed on rotting Opuntia cladodes. © 2016, Sociedad Venezolana de Entomología.

Nausigaster flukei Curran is recorded for the first time from Argentina. New specimens were collected in Mendoza, Jujuy and La Rioja provinces (Argentina), in the Monte and Chaco Phytogeographical Provinces. New records broaden the distribution of this species previously known from Paraguay and south Brazil and represent the first record of the genus Nausigaster from Argentina since 1892. © 2015 Check List and Authors.

New records of the endangered European genus and species Psarus abdominalis (Diptera, Syrphidae, Rhingiini) are provided together with a list of the Syrphidae collected in the Haut-Rhin Department. Based on these new records, the status of this highly endangered species is discussed. In addition, we give molecular data about Psarus abdominalis as part of the German Barcode of Life project, a contribution to a reference DNA library, as well as the detailed distribution of Psarus. © 2015 Société entomologique de France.

A new species of flower fly (Diptera: Syrphidae) is described, Paragus caligneus sp. nov. A full description with images is given, as well as a species key for the subgenus Afroparagus Vujić & Radenković, 2008 and a modification of the identification key for Paragus subgenera. Molecular sequences from mitochondrial cytochrome c oxidase I (COI) and nuclear ribosomal 28S rRNA genes were analyzed to evaluate the monophyly of Afroparagus. All four Paragus subgenera were recovered as monophyletic, although support values for Afroparagus were very low. © 2014, National Museum/Narodni muzeum. All rights reserved.

New taxonomic and distributional data on the genera Citrogramma Vockeroth, 1969 and Eosphaerophoria Frey, 1946 are presented, including descriptions of the females of Citrogramma asombrosum Mengual, 2012, Citrogramma pennardsi Mengual, 2012 and Eosphaerophoria dentiscutellata (Keiser, 1958). Modifications to published identification keys to ac-commodate the new information are provided for both genera.

The flower fly genus Asiobaccha Violovitsh is revised and 10 new species are described: A. aea Mengual & Thompson, A. albipeza Mengual, A. aquila Thompson & Mengual, A. doesburgi Mengual, A. marissae Mengual, A. maculosa Mengual & Thompson, A. notofasciata Thompson & Mengual, A. samoaensis Mengual, A. selsi Mengual and A. taronja Mengual. Moreover, lectotypes are designated for Baccha semifumosa Meijere, Baccha luteolimbata Meijere, Asiobaccha nubilipennis (Austen), A. praefica (Bezzi), A. virtuosa (Curran) and A. sauteri (Kertész), and a neotype for A. loriae (Meijere) is also designated. New synonyms are proposed: Baccha schistaceifrons Meijere and Baccha semifumosa Meijer are synonymised under Asiobaccha bicolor (Austen); Baccha luteolimbata Meijere is a junior synonym of Asiobaccha tinctiventris (Meijere); Baccha flavipes Doesburg is a junior synonym of Asiobaccha tripartita (Walker); Baccha gigas Curran is a junior synonym of Asiobaccha virtuosa Curran; and the syntypes of Baccha sulica Austen are synonymised under Asiobaccha bicolor (Austen) and Asiobaccha tripartita. Diagnoses, illustrations, synonymies and distributional data are given for all described species. Descriptions of new species as well as an identification key to all known species are also provided. © 2016 Informa UK Limited, trading as Taylor & Francis Group

The placement and phylogenetic relationships of Asiobaccha were explored using molecular evidence. The mitochondrial protein-coding gene cytochrome c oxidase subunit I (COI) and the nuclear 28S and 18S ribosomal RNA genes were analysed using parsimony, Bayesian inference and Maximum Likelihood. Two alignments approaches were used for rRNA genes: a multiple sequence alignment software, MAFFT, and their secondary structure. The present results do not place Asiobaccha close to Baccha or Allobaccha, which are placed in different evolutionary lineages, but close to Episyrphus and Meliscaeva. The relationship among these three genera is not fully resolved. Morphological characters are discussed and Asiobaccha stat. rev. is proposed as a valid genus. © 2015 Korean Society of Applied Entomology, Taiwan Entomological Society and Malaysian Plant Protection Society.
