A catalog of the Chamaemyiidae of Chile (Diptera: Lauxanioidea).

A catalog of the Chamaemyiidae of Chile is provided. We present all valid names and synonyms for the 14 species and eight genera and subgenera distributed in the country, including information about name, author, year of publication, page number, type-species, type depository, type locality and references. The chamaemyiid fauna of Chile is small, with the largest genus, Ortalidina Blanchard having only five species. Species of the subgenus Xenoleucopis Malloch of the genus Leucopis Meigen (even if referred to only as sp.) are the most cited due to their apparent potential as biological control agents, or the many works recording their biology. The geographical distribution of the different species was compiled from bibliographic data and revised collections.

Two new species of Dasybasis Macquart from the Peruvian Andes of Cusco (Diptera: Tabanidae: Diachlorini).

Two new horse fly species, Dasybasis mancoi sp. nov. and D. huaynai sp. nov. (Diptera: Tabanidae: Diachlorini), are described from the Peruvian Andes near Cusco on the basis of morphological features, including those of the female genitalia. Digital photographs of both species and of the terminalia of both females and of one male are provided. The two new species are related to D. bulbula Coscarn & Philip, as evidenced by their similar morphological characteristics.

A catalog of Nemestrinidae (Diptera: Brachycera: Nemestrinoidea) from Chile.

A catalog of the Nemestrinidae from Chile is provided. Included are all valid names and synonyms for the 37 species and four genera from Chile, including information about the name, author, year of publication, page number, type species, type locality, and references. Trichophthalma Westwood is the most species-rich genus in Chile, with eighteen species, followed by Hyrmophlaeba Rondani, with twelve species. The geographical distribution of species was recorded from the examination of bibliographic data, label data on specimens in collections, and records of citizen science. Biological interactions are provided for each species when possible.

Coenura Bigot as a valid genus: A molecular and morphological phylogenetic analysis of Pelecorhynchus Macquart sensu lato (Diptera: Pelecorhynchidae).

The phylogeny of the genus Pelecorhynchus Macquart (Diptera: Pelecorhynchidae) was analyzed using three genes, cytochrome oxidase I, 28S ribosomal DNA, and CAD5, with 112 morphological characteristics. A total of 59 specimens (13 outgroups and 46 ingroups) were included in the analysis. The monophyly of Pelecorhynchidae was recovered under all analyses, with Glutops Burgess as the sister group of Pelecorhynchus s.l., while Pseudoerinna jonesi (Cresson) was the sister group. Within Pelecorhynchus there are three main clades with unresolved affinities. Clade I was formed by P. personatus (Walker), P. vulpes (Macquart), P. penai Pechuman and P. kroeberi (Lindner), a well-supported clade. Clade II corresponds to the set of species of Chilean Pelecorhynchus, conformed to P. biguttatus (Philippi), P. toltensis Llanos & Gonzlez, P. elegans (Philippi), P. xanthopleura (Philippi), P. hualqui Llanos & Gonzlez, and P. longicauda (Bigot), a well-supported clade. Clade III is represented exclusively by P. fulvus Ricardo, which has an exclusively Australian distribution. The monophyly of P. fulvus and its nomenclature remain an open question, as only a single species of this taxon was included. Our study demonstrated that the concept of Pelecorhynchus should be revisited. Therefore, we restore Coenura Bigot, 1857 to generic status for part of the southern South American species of Pelecorhynchus conformed by the species C. biguttata, C. elegans, C. hualqui, C. longicauda, C. toltensis, and C. xanthopleura which are monophyletic, supported by molecular and morphological data, and consistent with a Chilean distribution.

Overview of the Sciomyzidae (Diptera: Sciomyzoidea) of the Americas south of the United States.

Treated herein are the 113 described species and two described subspecies in 25 genera of the family Sciomyzidae (snail-killing or marsh flies) known from the Americas south of the United States. Included are details on type specimens, references to generic transfers and synonymies, taxonomy, biology, gastropod hosts/prey, immature stages, chromosomes, biological and phenological groups, general distribution, and molecular data. Annotated keys are presented to adults of genera known from the Nearctic-Neotropical interface area and the Neotropics as well as the first key to all sciomyzid genera known from the Nearctic Region. Also presented is the first key to third-instar sciomyzid larvae in the Neotropical Region. Sepedonea isthmi (Steyskal) is placed as a junior synonym of S. annulata Macquart (new status), and Tetanocera plumifera Wulp is placed as a junior synonym of T. plumosa Loew (new status).

Catalog of the horse-flies (Diptera: Tabanidae) of Chile.

A catalog of the Tabanidae from Chile is provided. All valid names and synonyms for the 116 species and 25 genera known for the country including information about name, author, year of publication, page number, type species, type locality and references are listed. The species Dasybasis albohirta (Walker) is cited for the first time for Chile. The type locality of Dasybasis nigrifrons (Philippi) is corrected to Chile (Todos Los Santos Lake). The dates of the description of Tabanus nigrifrons Philippi (now Dasybasis), and Pangonia australis Philippi (now Pseudoscione) are corrected from their original description by Philippi; the original description dates for Tabanus andicola (now Dasybasis), and Tabanus magellanicus (now synonym junior of Dasybasis trita (Walker)) are corrected from 1865 to 1862. Three species previously recorded from Chile are deemed to have been misidentified or misrecorded from Chile: Esenbeckia (E.) cisandeana Wilkerson Fairchild and Esenbeckia (E.) enderleini Krber, and Esenbeckia (E.) testaceiventris (Macquart, 1848). The genus Dasybasis Macquart is the richest genus in Chile, with 33 species. Seven genera (Mycteromyia Philippi, Promycteromyia Coscarn Philip, Archeomyotes Philip Coscarn, Austromyans Philip Coscarn, Chaetopalpus Philippi, Pseudomelpia Enderlein, and Sixtomyia Krolow, Henriques Gonzlez), three subgenera (Esenbeckia (Astomyia) Burger, E. (Palassomyia) Fairchild, and Protodasyapha (Protodasyapha) Enderlein), and 64 species are known only from Chile. There are also one subgenus (Protodasyapha (Curumyia) Coscarn), and 36 specie with distribution shared only between Chile and Argentina.
