Abstract: Anthomyiidae is a cosmopolitan and diverse family of Calyptratae, and is routinely considered to play key roles in both ecology and agriculture. The higher-level phylogenetic classification of Anthomyiidae has been highly controversial, necessitating further molecular data for precise reconstruction of phylogenetic relationships. In this study, we successfully acquired and annotated 18 new mitogenomes of anthomyiids. Moreover, the mitogenomes of the following genera Eustalomyia, Hyporites, Leucophora, Emmesomyia and Eutrichota are reported for the first time. The 18 mitogenomes are compared with confamilial species to assess genetic variation and to better understand evolutionary relationships within the family Anthomyiidae. In comparisons among 13 mitochondrial protein coding genes (PCG), the calculation of evolutionary rate exhibited nad1 as the fastest evolving gene in Anthomyiidae. Among the anthomyiids investigated, cox2 and nad4 had the lowest genetic distance across the 13 PCGs, suggesting a high degree of conservation for these two genes. Herein, we conducted phylogenetic analyses of the newly sequenced mitogenomes along with 11 known anthomyiids to investigate the interrelationships of Anthomyiidae. Our results indicate that Anthomyiidae is a monophyletic lineage and sister group to Scathophagidae, confirming prior findings based on morphological and molecular analyses. We recovered two subfamilies as monophyletic (Myopininae, Pegomyinae) while Anthomyiinae was polyphyletic. The great species diversity of anthomyiid flies limits the availability of mitogenomes for accurately resolving the phylogeny of Anthomyiidae. Nonetheless, our study provides novel insight into the molecular taxonomy, evolution, and phylogeny of the family Anthomyiidae.

Comparative analysis of the complete mitochondrial genomes of three Zeugodacus species (Insecta: Tephriti­dae: Dacinae) and their phylogenetic relationships with other congeners https://arthropod-systematics.arphahub.com/article/105025/ Arthropod Systematics & Phylogeny 81: 747-759

DOI: 10.3897/asp.81.e105025

Authors: Hoi-Sen Yong, Sze-Looi Song, Kah-Ooi Chua, Yvonne Jing Mei Liew, I. Wayan Suana, Phaik-Eem Lim, Kok-Gan Chan, Praphathip Eamsobhana

Abstract: The complete mitogenomes of fruit flies Zeugodacus (Javadacus) calumniatus, Z. (Javadacus) heinrichi and Z. (Sinodacus) hochii have similar gene order and contain 37 genes and a non-coding region. They share an identical start codon for the respective protein-coding genes (PCGs), an identical TAA stop codon for 11 PCGs, TAG for cob, and an incomplete T stop codon for nad5. The cloverleaf structure of most of the tRNAs is similar in the three Zeugodacus species. Phylogenetic analyses reveal Z. (Parasinodacus) cilifer to be external to two main clades: (A) monophyletic subgenus Zeugodacus; and (B) subgenera Javadacus and Sinodacus. The present results indicate that the taxonomic status of some taxa needs clarification. Z. calumniatus is genetically very similar to Z. tau and is not congruent with its current placement in the munda complex. Z. mukiae NC_067083 is genetically very similar to Z. scutellaris, but differs significantly from Z. mukiae MG683384 of the arisanicus (arisanica) complex. On the other hand, Z. proprediaphorus is genetically distinct from and not a synonym of Z. diaphorus. Z. caudatus sensu stricto from Indonesia forms a sister lineage with Z. diversus, instead of with the Malaysian and Chinese taxa of Z. caudatus sensu lato. A notable incongruence is the sister lineage of Z. (Sinodacus) hochii and Z. (Javadacus) heinrichi among other taxa of subgenus Javadacus. A more extensive taxon sampling, particularly the subgenus Sinodacus (and other subgenera), is needed to clarify/resolve their subgenus status.

Phylogeny of the old and fragmented genus Austrocoenosia Malloch reveals new evidences on the morphology and evolution of the genera Coenosia Meigen and Neodexiopsis Malloch (Diptera: Muscidae) https://arthropod-systematics.arphahub.com/article/104969/ Arthropod Systematics & Phylogeny 81: 611-653

DOI: 10.3897/asp.81.e104969

Authors: Luciano Damián Patitucci, Pablo Ricardo Mulieri, Márcia Souto Couri, Martha Cecilia Domínguez

Abstract: Coenosiini (Diptera: Muscidae) is a large cosmopolitan tribe of muscids, within which Coenosia Meigen and Neodexiopsis Malloch are the genera with the largest number of species. In this work, we revised for the first time, all the species placed by Malloch (1934) under Austrocoenosia, an endemic genus from the Andean Patagonian Forests, whose species are now placed in Coenosia and Neodexiopsis. We provide detail redescriptions for eight species placed by Malloch (1934) under Austrocoenosia, and decribed two new species (Coenosia delneneo sp. nov. and Coenosia patagonica sp. nov.), with high quality photographs detailing new structures of the male and female terminalia. To establish the position of the species of Austrocoenosia with respect to Coenosia and Neodexiopsis, we made a phylogenetic analysis using implied weighting for 36 taxa and 132 morphological characters of adults, including male and female genitalia. We recovered all species of Austrocoenosia as Coenosia species. We propose the following nomenclature actions: Austrocoenosia as a junior synonymy of Coenosia (syn. rest.); Coenosia brevicornis (Malloch) (comb. nov.), Coenosia dubia (Bigot) (comb. rest.); Coenosia hucketti, Pont (nom. nov.) and Coenosia nigerrima (Malloch) (comb. rest.). We also propose Coenosia spumicola Pont as an unplaced species of Coenosia sensu lato. Finally, we updated the geographic distributions for all species and observed several new male and female terminalia structures, which enriched the discussion of the genera and the tribe.

Integrative species delimitation in the morphologically conservative Stegana subgen. Orthostegana (Diptera, Drosophilidae) https://arthropod-systematics.arphahub.com/article/102683/ Arthropod Systematics & Phylogeny 81: 581-610

DOI: 10.3897/asp.81.e102683

Authors: Ya-Lian Wang, Zi-Qi Peng, Feng-Liang Jin, Hong-Wei Chen, Jia Huang

Abstract: With the increasing number of cryptic species discovered in major branches of the subfamily Steganinae, accurate species identification is becoming challenging. Possible evolutionary stasis often gives rise to the formation of morphological conservatism and cryptic species, as is the case for the members of the Stegana (subgen. Orthostegana). In this study, the species boundaries of all Asian Orthostegana were accessed based on two mitochondrial genes [cytochrome c oxidase subunit I (COI) and NADH dehydrogenase subunit 2 (ND2)] using different species delimitation methods and evolutionary models. By integrating morphological and molecular evidence, we clearly validated the evolutionary independence of all five known species and identified nine new species from Southwest China: Stegana (Orthostegana) aini Peng & Chen sp. nov., S. (O.) brevivittata Peng & Chen sp. nov., S. (O.) cuodi Peng & Chen sp. nov., S. (O.) fuscofemorata Peng & Chen sp. nov., S. (O.) latipalpula Peng & Chen sp. nov., S. (O.) macrostephana Peng & Chen sp. nov., S. (O.) mohnihei Peng & Chen sp. nov., S. (O.) obscurala Peng & Chen sp. nov., and S. (O.) pinguitia Peng & Chen sp. nov. Moreover, we discussed the relationship between the Asian Orthostegana lineage and the subgen. Oxyphortica, and the necessity of taxonomic re-evaluation for the Neotropical species with molecular data. The high morphological conservatism within Orthostegana is largely the outcome of in situ diversification for adapting to the ecological environment.

Christelenkidae, a new extinct family based on a new taxon from Eocene Baltic amber (Diptera: Acalyptratae), with X-ray synchrotron microtomography imaging of its structures https://arthropod-systematics.arphahub.com/article/101441/ Arthropod Systematics & Phylogeny 81: 475-498

DOI: 10.3897/asp.81.e101441

Authors: Jindřich Roháček, Jörg U. Hammel, Viktor Baranov

Abstract: A new family of Diptera Acalyptratae, Christelenkidae Roháček fam. nov., is established for Christelenka multiplex Roháček gen. et sp. nov., an unusual extinct taxon described from a unique male specimen preserved in Baltic amber (Mid-late Eocene, ca 48–34 Ma). Apart from detailed examination by light microscopy and photography, the holotype of the new species has also been studied by means of X-ray synchrotron microtomography with the aim of obtaining additional morphological data for consideration of its relationships. Because of a very peculiar combination of morphological characters, the new family is tentatively considered a separate lineage of Acalyptratae having no apparent sister-group relationship with any of the known families. Its probable relationships to some families of Opomyzoidea and Ephydroidea are discussed.

Taxonomic revision of the Merodon tarsatus species group (Diptera, Syrphidae) https://arthropod-systematics.arphahub.com/article/93570/ Arthropod Systematics & Phylogeny 81: 201-256

DOI: 10.3897/asp.81.e93570

Authors: Ante Vujić, Snežana Radenković, Anatolij Barkalov, Nataša Kočiš Tubić, Laura Likov, Tamara Tot, Grigory Popov, Alex Prokhorov, Ebrahim Gilasian, Shehzad Anjum, Mihajla Djan, Banafsha Kakar, Andrijana Andrić

Abstract: The phytophagous hoverfly genus Merodon Meigen, 1803 (Diptera, Syrphidae) presently comprises 205 described species distributed in the Palaearctic and Afrotropical regions, and it is differentiated into multiple species groups. In this work, we revise the Merodon tarsatus species group, providing an illustrated key to species, a detailed discussion on relevant taxonomic characters, and a morphological diagnosis. We summarize morphological characteristics of the 12 species in the M. tarsatus group, together with available distributional data. Moreover, we provide descriptions for five new species, namely Merodon angustitarsis Vujić & Gilasian sp. nov., M. dumosus Vujić, Likov & Radenković sp. nov., M. latiantennatus Vujić, Popov & Prokhorov sp. nov., M. namaghijamii Vujić, Likov & Radenković sp. nov. and M. pakistanicus Vujić, Likov & Radenković sp. nov. Additionally, we describe one more species, Merodon nigroalatus Vujić, Likov & Radenković sp. nov., that belongs to the same lineage and is related to the Merodon tarsatus group based on molecular markers and structure of male genitalia, but lacks modifications of the metatarsus and sternum 4 that are the main diagnostic features of the group. Furthermore, we redefine and redescribe seven taxa of the M. tarsatus group. Following detailed analyses of type material, we revise the status of all available taxa related to M. tarsatus and we propose the following new synonyms: M. ankylogaster Hurkmans, 1993 syn. nov. (junior synonym of M. hypochrysos Hurkmans, 1993); M. persicus Hurkmans, 1993 syn. nov. (junior synonym of M. oidipous Hurkmans, 1993); and M. xanthipous Hurkmans, 1993 syn. nov. (junior synonym of M. marginicornis Hurkmans, 1993). We apply Maximum Parsimony and Maximum Likelihood analyses of the 5′ end of the mitochondrial COI gene sequences to genetically characterize species in the M. tarsatus group and the related species, M. nigroalatus Vujić, Likov & Radenković sp. nov.

Integrating morphology and DNA barcodes for identification of Delia sanctijacobi Bigot 1885 (Diptera: Anthomyiidae): new host and new records in South America https://arthropod-systematics.arphahub.com/article/82831/ Arthropod Systematics & Phylogeny 80: 511-522

DOI: 10.3897/asp.80.e82831

Authors: Lucas Roberto Pereira Gomes, Maria Aparecida Cassilha Zawadneak, Magda Clara Vieira da Costa-Ribeiro, Tiago Miguel Jarek, Claudio José Barros de Carvalho

Abstract: Delia sanctijacobi is critically assessed and given a revised description using data from scanning electronic microscopy (SEM) and DNA barcode analysis. This species is recorded for the first time in Brazil and Peru. We provide a morphological identification key (with figures) for Delia species from Brazil, a molecular identification based on COI (cytochrome C oxidase subunit I) barcode sequences and an updated distributional map. We also report the first occurrence of D. sanctijacobi feeding on Brassica species in Brazil. This potential pest was observed in broccoli roots (Brassica oleracea var. italica; Brassicaceae) in União da Vitória, Paraná, southern Brazil, in August and September of 2017. The infested plants displayed reduced growth due to damage to the stem base or death if severely attacked.

Phylogenetic analysis of the tribe Dufouriini (Diptera: Tachinidae) using a total evidence approach based on adult and immature stages https://arthropod-systematics.arphahub.com/article/69618/ Arthropod Systematics & Phylogeny 80: 1-38

DOI: 10.3897/asp.80.e69618

Authors: Marcelo Domingos de Santis, Silvio Shigueo Nihei

Abstract: Abstract Dufouriini are a worldwide distributed tachinid tribe comprised of 51 species in 13 genera, made up of parasitoids of adult Coleoptera. The systematic positioning of Dufouriini has been controversial. Currently, it is placed within Dexiinae, but was previously placed in Phasiinae and Voriinae, and has even had the status of subfamily. Delimitation and composition of Dufouriini has also been debated, whether it is a single tribe or divided into two (Dufouriini and Freraeini) or three (Dufouriini, Oestrophasiini and Freraeini) tribes. Herein, we present the first phylogenetic analysis of Dufouriini based on total evidence using morphological data from adult and immature stages. The taxonomic sampling included all genera in Dufouriini (including Oestrophasiini) and also the genus belonging to Freraeini, a historically related tribe. Data matrix comprised 35 species and 22 genera in the ingroup, and 185 characters constructed from eggs, first instar larvae, puparia and adults, including female and male terminalia and spermathecae. The phylogenetic analysis recovered Dexiinae as paraphyletic in relation to Phasiinae, since the clade (Freraeini (Dufouriini + Oestrophasiini)) is more closely related to Phasiinae than Dexiinae. Dufouriini, Oestrophasiini and Freraeini are recovered as separate monophyletic tribes, strongly supported by a number of synapomorphies. Oestrophasiini is revalidated. A new synonymy is proposed: Comyopsis Townsend syn. nov. of Ebenia Macquart. Accordingly, Ebenia fumata (Townsend, 1919) is nomen preoccupatum by Ebenia fumata (Wulp, 1891), thus we change its specific epithet by designation of the new replacement name Ebenia neofumata Santis and Nihei [nomen novum]. The genera Mesnilana and Rhinophoroides are removed from Dufouriini and tentatively placed into Palpostomatini. Finally, Cenosoma stat. rev., previously a subgenus of Oestrophasia, is revalidated as genus.

Review of the Merodon natans group with description of a new species, a key to the adults of known species of the natans lineage and first descriptions of some preimaginal stages https://arthropod-systematics.arphahub.com/article/65861/ Arthropod Systematics & Phylogeny 79: 343-378

DOI: 10.3897/asp.79.e65861

Authors: Ante Vujić, Tamara Tot, Andrijana Andrić, Jelena Ačanski, Ljiljana Šašić Zorić, Celeste Pérez-Bañón, Andrea Aracil, Sanja Veselić, Maja Arok, Ximo Mengual, André van Eck, Santos Rojo, Snežana Radenković

Abstract: Abstract Merodon natans group (Diptera, Syrphidae) taxa are reviewed using an integrative taxonomic approach combining morphological, morphometric and molecular techniques. The approach substantiates recognition of the three species: M. calcaratus (Fabricius, 1794), M. natans (Fabricius, 1794) and M. pulveris Vujić & Radenković in Radenković et al. 2011, and reveals the existence of a new species, M. makrisi Vujić, Radenković & Tot sp. nov., which is described. It also highlights the existence of a series of natans group populations, especially on some of the Mediterranean islands, in the Levant and in the Afrotropical Region, for which more comprehensive data are required to clarify their status. A key is provided to the natans lineage species currently recognised, and preimaginal stages of some natans-group species are described for the first time. Redescriptions for M. calcaratus and M. natans are provided. A neotype is selected for M. natans. Lectotypes are designated for M. annulatus (Fabricius, 1794) and M. melancholicus (Fabricius, 1794). Merodon annulatus is recognised as a synonym of M. natans.
