“…Additionally, in Lamachella cua is distinctly shorter than bm, a pterostigma is usually present, m-cu is more elongate and not in near alignment with CuA, and R2+3 is sinuate, unlike Pouillonhybos (Smith, 1969: figs 137-138;Sinclair & Cumming, 2017). Chillcottomyia Saigusa, 1986, Stenoproctus Loew, 1858, and the Miocene genus Syneproctus Solórzano-Kraemer et al, 2020 have cell cua quite shorter than bm, and with apex convex, nearly perpendicular to the two veins CuA and CuP, unlike Pouillonhybos (Smith, 1969: figs 127-128, 130;Yang & Grootaert, 2004;Solórzano-Kraemer et al, 2020).…”

The first ocydromiine hybotid fly is described and illustrated from a remarkable male preserved in mid-Cretaceous amber from northern Myanmar. Pouillonhybos venator, gen. et sp. nov., is distinguished from other members of the subfamily Ocydromiinae as well as other lineages of living and fossil Hybotidae. The holotype of P. venator exhibits spectacular specializations of the mid and hind legs, modifications likely linked to the grasping of prey either during capture and/or while feeding. The species reported here is the earliest evidence of significant leg modifications in Hybotidae indicating an early appearance of such specializations in the family's history.

“…Moreover, an impression fossil specimen from the Cretaceous of Botswana was assigned to the extant genus Empis based on wing characters (Waters, 1989). To date, Cenozoic deposits mostly yield “modern” empidoid forms, which have been assigned to extant genera (Carpenter, 1992), with a few exceptions (Cumming and Brooks, 2002; Solórzano‐Kraemer et al., 2020; Shamshev and Perkovsky, 2022).…”

Dance flies and relatives (Empidoidea) are a diverse and ecologically important group of Diptera in nearly all modern terrestrial ecosystems. Their fossil record, despite being scattered, attests to a long evolutionary history dating back to the early Mesozoic. Here, we describe seven new species of Empidoidea from Cretaceous Kachin amber inclusions, assigning them to the new genus Electrochoreutes gen.n. (type species: Electrochoreutes trisetigerus sp.n.) based on unique apomorphies among known Diptera. Like many extant dance flies, the males of Electrochoreutes are characterized by species-specific sexually dimorphic traits, which are likely to have played a role in courtship. The fine anatomy of the fossils was investigated through high-resolution Xray phase-contrast microtomography to reconstruct their phylogenetic affinities within the empidoid clade, using cladistic reasoning. Morphology-based phylogenetic analyses including a selection of all extant family-and subfamily-ranked empidoid clades along with representatives of all extinct Mesozoic genera, were performed using a broad range of analytical methods (maximum parsimony, maximum-likelihood and Bayesian inference). These analyses converged in reconstructing Electrochoreutes as a stemgroup representative of the Dolichopodidae, suggesting that complex mating rituals evolved in this lineage during the Cretaceous.

A catalog of the Hybotidae of Chile is provided. We present all valid names and synonyms for the 27 species and 10 genera distributed in the country, including information about name, author, year of publication, page number, type species, type depository, type locality and references. The geographical distribution of the species was recorded from bibliographic data and revised collections. Two species previously recorded for the Hybotidae fauna of Chile must be deleted: Drapetis armipes Bezzi, described from Tacna – Peru, and Ocydromia philippii Bigot, a synonym junior of Hyperperacera nemoralis (Philippi), now in Brachystomatidae (Trichopezinae). Bicellaria collina (Philippi) and Austrodromia? valdiviana (Philippi) are maintained in Hybotidae waiting for clarification of correct taxonomic assignment.
