“…The monotypic Nearctic Goniops is resolved as sister to the Philolichini and the rest of Scionini. The placement, unusual morphology and biogeographic disjunction of Goniops corroborate its removal from Scionini (Lessard et al , ; Lessard, ).…”

“…Additionally, the genus Caenopangonia Kröber, previously considered a synonym of Mycteromyia , was moved by Coscaron & Philip () to Scionini. Lessard () excluded Goniops and Caenopangonia from Scionini, returning Caenopangonia to Mycteromyiini and placing Goniops in a monobasic Goniopsini. The three genera included in Scepsidinae ( sensu Mackerras, ), have also been given various ranks, including being placed within Pangoniinae.…”

Horse flies, family Tabanidae, are the most diverse family-level clade of bloodsucking insects, but their phylogeny has never been thoroughly explored using molecular data. Most adult female Tabanidae feed on nectar and on the blood of various mammals. Traditional horse fly classification tends towards large heterogeneous taxa, which impede much-needed taxonomic work. To guide renewed efforts in the systematics of horse flies and their relatives, we assembled a dataset of 110 exemplar species using nucleotide data from four genes -mitochondrial CO1, and nuclear 28S, CAD and AATS. All commonly recognized tribes in Tabanidae are represented, along with outgroups in Tabanomorpha. The phylogeny is reconstructed using Bayesian inference, and divergence times are estimated using Bayesian relaxed clock methods with time constraints from tabanid fossils. Our results show Athericidae strongly supported as the lineage most closely related to Tabanidae, and Pangoniinae and Tabaninae as monophyletic lineages. However, Chrysopsinae is nonmonophyletic, with strong support for both a nonmonophyletic Bouvieromyiini and for Rhinomyzini as sister to Tabaninae. Only the tribes Philolichini, Chrysopsini, Rhinomyzini and Haematopotini are recovered as monophyletic, although Scionini is monophyletic with exclusion of the peculiar genus Goniops Aldrich. Mycteromyia Philippi and Adersia Austen, two enigmatic genera sometimes placed in separate family-level groups, are recovered inside Pangoniini and Chrysopsini, respectively. Several species-rich genera are not recovered as monophyletic, including Esenbeckia Rondani, Silvius Meigen, Dasybasis Macquart and Tabanus L. Tabanidae likely originated in the Cretaceous, and all major extant groups were present by the early Palaeogene. This newly revised phylogenetic framework for Tabanidae forms the basis for a new assessment of tabanid diversification and provides context for understanding the evolution of trophic specialization in horse flies.

“…Here, we address some taxonomic problems and inconsistencies in the papers by Lessard et al (2013) and Lessard (2014), and their implications in the classification of Neotropical Scionini. Our argumentation and discussion will be based upon the examination of certain species, on the morphological background available for the group and published taxonomic revisions for Neotropical Tabanidae, especially with species included in the genus Lepmia by Lessard et al (2013) and Lessard (2014).…”

“…In the subsequent year, aiming to formalize the new proposal of taxonomic classification, Lessard (2014) published the "Revision of the austral horse fly tribe Scionini (Diptera: Tabanidae)," where he updated the nomenclature data about the tribe, described a new genus and tribe, provided identification keys for tribes of Pangoniinae and for the genera and subgenera of Scionini, presented diagnoses for genera and subgenera, and compiled a list of species. Moreover, he used morphological characters to fit the genera not sampled in the phylogeny of Lessard et al (2013) into their molecular-based tree.…”

“…The papers of Lessard et al (2013) and Lessard (2014) present great advances and introduce new hypotheses and facts in the phylogeny and classification of Scionini; its impact and contribution are undeniable. However, we detected some problems and inconsistencies that have repercussions for the proposed classification, which we want to point out and discuss here.…”

Comments on the Classification of Neotropical Scionini (Tabanidae) with a Description of a New Genus

et al. 2020

View full text Add to dashboard Cite

The classification of the Tabanidae had remained stable over the last 60 years after Mackerras proposed a great revolution in the arrangement of the family. Recently, some new proposals based on molecular data have once again changed the classification of the family, mainly with a focus on the tribe Scionini. The present paper introduces a critical analysis based on the taxonomical view of the recent proposed classification of Scionini. Three genera are discussed: Lepmia Fairchild, Parosca Enderlein, and Pseudoscione Lutz. Lepmia atra (Philippi), L. grisea (Jaennicke), and L. leucothorax (Ricardo) are transferred to a new genus, Sixtomyia gen.n., based on its morphological differences from Lepmia. Other three species receive a new combination: Parosca subulipalpis (Enderlein) n. comb., Pseudoscione albifrons (Macquart) n. comb., Ps. hibernus (Wilkerson & Coscarón) n. comb. A key to species of Sixtomyia is provided and diagnostic characters are illustrated.

Description of the Terrestrial Larva of Parosca latipalpis (Macquart) (Diptera: Tabanidae) from Southern Chile

The terrestrial larva of the austral horsefly, Parosca latipalpis (Macquart), identified by molecular techniques, is described. The larva of P. latipalpis resembles Scaptia auriflua (Donovan), Copidapha vicina (Taylor), Myioscaptia muscula (English), and Osca lata (Guérin-Meneville) in many morphological characters, as well as in their terrestrial habitats. Some characters that are shared between these species are unique among Tabanidae and provide evidence of their monophyletic origin, suggesting a typical Gondwanaland group. Larvae of P. latipalpis were found 2-3 cm below of the soil surface and associated with larvae of Coleoptera, Lepidoptera, and Diptera in southern Chile.
