A new monotypic genus is described and illustrated based on the species Pugliesemyia titiznana gen. nov. et sp. nov. from the Caatinga domains of the state of Pernambuco, Brazil. It belongs to the small group of genera in the Neotropical region (Stonyx Osten Sacken, Lepidanthrax Osten Sacken, Rhynchanthrax Painter) among the tribe Villini, with a projecting proboscis. In addition, we also provide an updated identification key to the known Brazilian genera of Villini, description and illustrations of the pupal case, bionomic remarks on the feeding habits and the host record of the species and a brief discussion on Villini systematics and boundaries of their genera.

Taxonomic review of the Strongylophthalmyia ustulata group (Diptera: Brachycera: Strongylophthalmyiidae) from China, with the descriptions of three new species.

The Strongylophthalmyia ustulata group (Diptera: Brachycera: Strongylophthalmyiidae) from China is revised. Five species are recognized, including three new species (S. elongata sp. nov., S. flavimarginata sp. nov., and S. sivelli sp. nov.) and one new record species [S. ustulata (Zetterstedt, 1847)]. Strongylophthalmyia yaoshana Yang & Wang, 1998, previously placed in the S. ustulata group, is herein transferred to the S. fascipennis group based on its bare antennal arista and patterned wing. A key to the Chinese species of the S. ustulata group is provided.

First record of Mythicomyia Coquillett, 1983 from Colombia with description of a new species of Mythicomyia (Heterhybos) Brthes, 1919 (Diptera: Mythicomyiidae: Mythicomyiinae) and an updated key to South American species.

Mythicomyia Coquillett (1893) has a disjunct distribution (presence in every biogeographical region with the exception of the Palearctic) and is a poorly studied group in the Neotropical Region, and completely unknown in Colombia. Its subgenus Heterhybos Brthes has a Nearctic and Neotropical distribution. Of the nine species in the Neotropical Region (in Argentina, Chile, and Uruguay), all occur in Chile and only one in Argentina and Uruguay. A new species of Mythicomyia (Heterhybos) is here described from Colombia: Mythicomyia (Heterhybos) bilobata sp. nov. (type-locality: Liborina, La Sucia). Illustrations of the new species, dichotomous key (males and females) and distribution map of the South American species are also presented.

New Amydrostylus Lamas, Falaschi & Evenhuis (Diptera, Mythicomyiidae, Psiloderoidinae) from the Brazilian semiarid region, with discussion on the unusual male terminalia of the genus.

The studying material were recently collected with Malaise traps in Northeastern Brazil, and the authors found a new species of Amydrostylus, which represents the second known species of this endemic genus from the open/dry biomes of Brazil. The discovery results will provide more new diagnosis for the genus and allow a better knowledge of the male terminalia morphology, leading to a new interpretation of some of its structures. Male and female specimens are described and illustrated here.

A new species of Glabellula Bezzi, 1902 (Diptera: Mythicomyiidae: Glabellulinae) from Colombia, and an updated key to South American species.

Glabellula Bezzi, 1902 has a cosmopolitan distribution and is a poorly studied group in the Neotropical Region, and completely unknown in Colombia. One new species of Glabellula is described from Colombia, namely Glabellula antioquensis sp. nov. (type-locality: Buriticá, La Angelina). Illustrations and a dichotomous key to the South American species are presented.

A review of the Strongylophthalmyiacoarctata subgroup (Diptera, Brachycera, Strongylophthalmyiidae) from China, with the descriptions of three new species.

The species belonging to the Strongylophthalmyiacoarctata subgroup of the S.punctata group (Diptera: Brachycera: Strongylophthalmyiidae) from China are reviewed. Six species are recognized, including three new species: S.corniculatasp. nov., S.flagellicornissp. nov., and S.tangwanganasp. nov.Strongylophthalmyianarwhal Evenhuis, 2020 and S.raricornis Shatalkin, 1981 are recorded from China for the first time, and S.raricornis is also recorded from South Korea for the first time.

An identification key to the Brazilian species is also presented. This paper presents the first records of Glabellula in South America and the presence, for the first time, of the subfamily Glabellulinae in Brazil.

The subgenus Empidideicus (Anomaloptilus) (Diptera: Mythicomyiidae) in Madagascar.

The relatively uncommonly encountered subgenus Empidideicus (Anomaloptilus) is shown to be fairly diverse in Madagascar with eight known species. The subgenus is concentrated primarily in Southern Africa and Madagascar, ranges eastward through Arabia to Kazakhstan, and has a small disjunct population in the Canary Islands. Previous to this study, only one species was known from Madagascar (E. rhinoclypeatus Evenhuis). Including those described in this study, 18 species are now known in the subgenus worldwide, eight endemic to Madagascar, seven of which are herein described as new: E. (A.) andriambahomananii, n. sp., E. (A.) contrasticus, n. sp., E. (A.) hauseri, n. sp., E. (A.) irwini, n. sp., E. (A.) nanus, n. sp., E. (A.) regius, n. sp., and E. (A.) rinhai, n. sp. A key to the subgenera of Empidideicus and also to the species of the subgenus Anomaloptilus in Madagascar is given.

Phylogenomics reveals accelerated late Cretaceous diversification of bee flies (Diptera: Bombyliidae).

Bombyliidae is a very species-rich and widespread family of parasitoid flies with more than 250 genera classified into 17 extant subfamilies. However, little is known about their evolutionary history or how their present-day diversity was shaped. Transcriptomes of 15 species and anchored hybrid enrichment (AHE) sequence captures of 86 species, representing 94 bee fly species and 14 subfamilies, were used to reconstruct the phylogeny of Bombyliidae. We integrated data from transcriptomes across each of the main lineages in our AHE tree to build a data set with more genes (550 loci versus 216 loci) and higher support levels. Our overall results show strong congruence with the current classification of the family, with 11 out of 14 included subfamilies recovered as monophyletic. Heterotropinae and Mythicomyiinae are successive sister groups to the remainder of the family. We examined the evolution of key morphological characters through our phylogenetic hypotheses and show that neither the "sand chamber subfamilies" nor the "Tomophthalmae" are monophyletic in our phylogenomic analyses. Based on our results, we reinstate two tribes at the subfamily level (Phthiriinae stat. rev. and Ecliminae stat. rev.) and we include the genus Sericosoma Macquart (previously incertae sedis) in the subfamily Oniromyiinae, bringing the total number of bee fly subfamilies to 19. Our dating analyses indicate a Jurassic origin of the family (165-194 Ma), with the sand chamber evolving early in bee fly evolution, in the late Jurassic or mid-Cretaceous (100-165 Ma). We hypothesize that the angiosperm radiation and the hothouse climate established during the late Cretaceous accelerated the diversification of bee flies, by providing an expanded range of resources for the parasitoid larvae and nectarivorous adults.

A case of two spellings for Humboldt's blue-winged mosquito (Diptera: Culicidae).

While adding taxon names to the Systema Dipterorum database (Evenhuis Pape 2021), one of us (NLE) discovered that Humboldt (1819) had spelled the proposed name of a nominal mosquito species in two ways. He described the species, which was found in swampy places along the Magdalena River near Tenerife, Colombia, as Culex cyanopennis on page 340 and afterwards referred to it as Culex cyanopterus on pages 345 and 349. Both names have the same meaning: cyano- (Gr. kyanos, dark blue), pennis (L. penna, feather, wing) and pteron (Gr. feather, wing). The species was named for the perceived color of the wings: "Alæ cæruleæ, splendore semi-metallico…" (wings blue, a bright semi-metallic). On page 345, Humboldt states, translated from the French: "We have been informed in the Rio de la Magdalena that in Simitì no other Culex than the jejen [je·jén: Sp., gnat, mosquito] was known in the past. You can spend the night there quietly, because the jejen is not a nocturnal insect. Since the year 1801, the big blue-winged mosquito (Culex cyanopterus) has shown itself in such abundance that the poor inhabitants of Simitì do not know how to get a peaceful sleep." Thus, in addition to having the same meaning, the two names are associated with the same locality.

Twenty years of Dipterology through the pages of Zootaxa.

We present a summary and analysis of the Diptera-related information published in Zootaxa from 2001 to 2020, with a focus on taxonomic papers. Altogether, 2,527 papers on Diptera were published, including 2,032 taxonomic papers and 1,931 papers containing new nomenclatural acts, equivalent to 22% of all publications with new nomenclatural acts for Diptera. The new nomenclatural acts include 7,431 new species, 277 new genera, 2,003 new synonymies, and 1,617 new combinations. A breakdown by family of new taxa and new replacement names proposed in the journal during the last two decades is provided, together with a comparison of Zootaxa's output to that of all other taxonomic publications on Diptera. Our results show that the journal has contributed to 20% of all biodiversity discovery in this megadiverse insect order over the last 20 years, and to about 31% in the last decade.

The hazards of Nomenclatural Archaeology? The Diptera names of Theodorus van Swinderen in his 1822 Index Rerum Naturalium quae conservantur in Museo Academico Groningano.

The Diptera names listed by Theodorus van Swinderen in his list of animals and minerals in the Groningen Natural History Museum are itemized and annotated. Most of the names listed, including those newly proposed, are synonymous with previously published names. One (Sarcophaga Swinderen, 1822) is a senior synonym of the well-known Sarcophaga Meigen, 1824. It has been dealt with in a previous paper, and Sarcophaga Swinderen, 1822 is now declared a nomen oblitum. The following new synonymies are proposed herein: Acolasta Swinderen, 1822 = Sepedon Latreille, 1804, n. syn. [Sciomyzidae]; Cleona Swinderen, 1822 = Callomyia Meigen, 1804, n. syn. [Platypezidae]; Cleona acuminata Swinderen, 1822 = Callomyia elegans Meigen, 1804, n. syn. [Platypezidae]; Driope Swinderen, 1822 = Dorycera Meigen, 1830, n. syn. [Ulidiidae]; Macrostoma Swinderen, 1822 = Volucella Geoffroy, 1762, n. syn. [Syrphidae]; Marsupium Swinderen, 1822 = Sphegina Meigen, 1822, n. syn. [Syrphidae]; Nycteria Swinderen, 1822 = Pipiza Fallén, 1810, n. syn. [Syrphidae]; Pacystoma Swinderen, 1822 = Medetera Fischer von Waldheim, 1819, n. syn. [Dolichopodidae]; Penthesilia Swinderen, 1822 = Merodon Meigen, 1803, n. syn. [Syrphidae]; Tromera Swinderen, 1822 = Madiza Fallén, 1810, n. syn. [Milichiidae]. Titania Swinderen, 1822 (preoccupied by Titania Meigen, 1800) and its type species Titania albipennis Swinderen, 1822 are available names, but are considered here as nomina dubia and unplaced within Diptera. Thericas Swinderen, 1822 is considered unavailable as it is not accompanied by a description or a definition and is based on an unavailable name. Dorycera Meigen, 1830 is declared a nomen protectum and Driope Swinderen, 1822 is declared a nomen oblitum; Medetera muralis Meigen, 1824 is declared a nomen protectum and Pacystoma muralis Swinderen, 1822 a nomen oblitum.

A new genus for Painter amp; Painter's Villa "celer"-group in the New World (Diptera: Bombyliidae).

The bee fly genus Hemipenthes Loew in the New World reflects a heterogeneous assemblage of species. Study of species attributed to Painter Painter's 1962 Villa "celer" group (the species were later transferred to Hemipenthes) from the southern United States, and Central and South America shows a suite of characters that separate it from Hemipenthes s. str. and it is here described as the new genus Ins Evenhuis, n. gen. with its type species Anthrax ignea Macquart. Eight described species are here transferred to Ins: Ins celeris (Wiedemann, 1828), n. comb., Ins constituta (Walker, 1852), n. comb.; Ins curta (Loew, 1869), n. comb., Ins ignea (Macquart, 1846), n. comb.; Ins leucocephala (Wulp, 1886), n. comb., Ins martinorum (Painter, 1962), n. comb., Ins minas (Macquart, 1848), n. comb., and Ins pleuralis (Williston, 1901), n. comb. Two new species, Ins pectorcolumbo Evenhuis, n. sp. from El Salvador and Ins zanouts Evenhuis, n. sp. from Panama and Costa Rica are described and illustrated. The holotype of Anthrax divisa Walker, 1852, has been examined and found to be conspecific with Ins minas (Macquart, 1848), n. syn., and Anthrax galathea Osten Sacken, 1886 is found to be synonymous with Ins constituta (Walker, 1852), n. syn. Two other South American species currently in Hemipenthes, H. melaleuca (Wiedemann), and H. ruficollis (Bigot) are here transferred to Chrysanthrax, n. combs. A key to species in the genus is given.
