Two new species of Leptomorphus Curtis, L. guatemalensis sp. n. and L. juxtafurcatus sp. n., are described from Guatemala, figured, and compared with congeners. The new species belong to the clade including the \“furcatus\” and \“walkeri\” species-groups as defined by Borkent \& Wheeler (2012). L. guatemalensis sp. n. can be recognized by the gonocoxite bulbous and crescent-shaped with the apex asetose and spatula-like, but remains without a clear sister-species. Based on the structure of the male terminalia, particularly the presence of submedian, pointed lobes on sternite nine, L. juxtafurcatus sp. n. is suggested to be the sister-species to L. furcatus Borkent from the southwestern USA and northern Mexico; these species can be distinguished by the form of the gonocoxites.

A new fossil genus of Bibionidae (Diptera: Bibionomorpha), Burmahesperinus gen. nov., from the mid-Cretaceous Burmese amber, is described and illustrated (type species Burmahesperinus antennatus sp. nov., the other two species included are B. conicus sp. nov. and B. pedicellatus sp. nov.). The new genus is tentatively placed in a new subfamily, Burmahesperininae subfam. nov. of the family Bibionidae. Its possible phylogenetic position is briefly discussed. The new genus, as well as the subfamily, possesses the wing venation similar to the recent genus Hesperinus Walker, 1848, in combination with Brachycera-like modification of both the male and female antenna and the overall habitus typical of fungus gnats (Sciaroidea).

A new species\—Docosia caucasica sp. n.\—has been described from material collected from the Lesser Caucasus Mountains in Georgia (Sakartvelo). The new species belongs to a group of Palaearctic species characterized by distinct posterolateral processes of gonocoxites and apically modified setae at the posteroventral margin of the gonocoxites medially. Within the group, D. caucasica sp. n. is most similar to D. landrocki Laštovka and Šev{\v c}ík, 2006 in having a similar outline of the medial process of posteroventral margin of the gonocoxites and the gonostylus. There is also a marked difference within the partial cytochrome c oxidase subunit 1 gene (COI) sequence of D. caucasica sp. n. and other Docosia spp. available in public databases. As the new species is described from a single male specimen only, the adequacy and code compliance of that are discussed

In this study, we use low-coverage shotgun sequencing of genomic DNA, commonly referred to as genome skimming, to investigate the phylogenetic relationships of the fungus gnat genus Allodia Winnertz (Mycetophilidae, Mycetophilinae, Exechiini). Nineteen specimens, representing 16 in-group and three outgroup taxa, were successfully sequenced and molecular markers of both mitochondrial and nuclear origin were retrieved. The phylogenetic analyses of 13 protein-coding mitochondrial genes, two ribosomal mitochondrial genes and the nuclear ribosomal 18S and 28S strongly support the monophyly of its two subgenera Allodia s.s. and Brachycampta. Complete mitochondrial genomes of 15 species were assembled, which enables further comparisons with the mitochondrial genomes of other Diptera. Overall, the methodology used in this study proved successful and promising for other dipteran groups. In addition to the phylogenetic reconstruction, the morphological characters previously used to separate the two subgenera were evaluated and re-examined. Together with the composite structure of the male genitalia, we consider details of the scutal bristles appropriate for separating the two groups. Based on the achieved results, we reinstate Brachycampta stat. rev. as a separate genus.

Exechia is a diverse genus of small fungus gnats, widespread in the Holarctic Region, while the fauna is largely unknown elsewhere, such as in the Afrotropical and Oriental Region. Members of Exechia can be arranged into several species groups, based on homologies in the male and female terminalia. The Exechia parva group is delimited, based on male terminalia possessing a pair of gonocoxal lobes on the apicoventral gonocoxal margin. Eight previously-described species can be placed in this group, of which six are from the Holarctic Region, while one is recorded each from the Oriental and the Afrotropical Regions.The Exechia parva group was reviewed and found to include 33 species, of which 24 were described as new to science and six were re-described. Identification keys to 32 species for males and nine species for females are provided together with illustrations and photos of male and female terminalia. Species delimitations were based on morphological examination of 94 male and female specimens, as well as DNA barcodes obtained from 124 specimens. Molecular and morphological species delimitations were mostly congruent, except in two cases where two species were delimited within a single Barcode Index Number (BIN). We found that each species is only known from a single zoogeographical region and that several species complexes are largely congruent with zoogeographical divisions, indicating that intercontinental barriers may have a strong impact on the species diversity of the group.

Average annual temperatures in the Arctic increased by 2\–3 \°C during the second half of the twentieth century. Because shorebirds initiate northward migration to Arctic nesting sites based on cues at distant wintering grounds, climate-driven changes in the phenology of Arctic invertebrates may lead to a mismatch between the nutritional demands of shorebirds and the invertebrate prey essential for egg formation and subsequent chick survival. To explore the environmental drivers affecting invertebrate availability, we modeled the biomass of invertebrates captured in modified Malaise-pitfall traps over three summers at eight Arctic Shorebird Demographics Network sites as a function of accumulated degree-days and other weather variables. To assess climate-driven changes in invertebrate phenology, we used data from the nearest long-term weather stations to hindcast invertebrate availability over 63 summers, 1950\–2012. Our results confirmed the importance of both accumulated and daily temperatures as predictors of invertebrate availability while also showing that wind speed negatively affected invertebrate availability at the majority of sites. Additionally, our results suggest that seasonal prey avail- ability for Arctic shorebirds is occurring earlier and that the potential for trophic mismatch is greatest at the northernmost sites, where hindcast invertebrate phenology advanced by approximately 1\–2.5 days per decade. Phenological mismatch could have long-term population-level effects on shorebird species that are unable to adjust their breeding schedules to the increasingly earlier invertebrate phenologies.

The fungus gnats of Georgia are studied based on 2682 specimens collected from 57 localities during 2011\–2019. Altogether, 245 species are recorded including four species of Bolitophilidae, three species of Diadocidiidae, two species of Ditomyiidae, 34 species of Keroplatidae and 202 species of Mycetophilidae. 230 and 188 species are recorded from Georgia and the whole of Transcaucasia for the first time, respectively. Three new species \– Sciophila georgei sp. nov., Leia katae sp. nov. and Anatella metae sp. nov. \– are described including detailed illustrations of the male terminalia. Photographs are provided for an additional 38 species to highlight a variability of their general facies. Combined with earlier published data, the number of fungus gnat species in Georgia is set at 246. The estimated diversity of fungus gnats in Georgia is calculated using non-parametric methods and discussed with respect to other Western Palaearctic regions.

The relationships among the genera of fungus gnats in the mycetophilid subfamily Leiinae are unclear, and the monophyly of this group is questionable. This monograph provides an extensive phylogenetic study of theLeiinae based on morphological data from a large taxonomic sample, including all genera that have ever been assigned to the subfamily and a wide outgroup sampling to properly test subfamilial monophyly. A data matrix with 128 morphological features of 117 terminal taxa was carried out under parsimony using different implicit weight schemes. All recovered topologies support a monophyletic Leiinae that is more restricted than the usual delimitation of the subfamily. We found no consistent evidence that a clade with Docosia Winnertz, Novakia Strobl, Ectrepesthoneura Enderlein, and Tetragoneura Winnertz group together with the remaining genera of Leiinae. A name with subfamily rank--Tetragoneurinae, already present in the literature--is used here to refer to this group. The allactoneurine genera Sticholeia S\øli and Allactoneurade Meijere form a clade with the leiine genus Leiella and the genera of Manotinae, which is deeply nested within the Leiinae. The male terminalia patterns found within the subfamily are analyzed and illustrated. A classification for the Leiinae is proposed grouping 33 genera in seven clades ranked as tribes: Selkirkiini Enderlein, Megophthalmidiini, trib. nov., Rondaniellini, trib. nov., Cycloneurini Shaw and Shaw, Manotini Edwards, Anomalomyiini, trib. nov., and Leiini Edwards. A key for the world genera of Leiinae is also provided. The Cretaceous mycetophilid fossil record is revisited and the biogeographic evolution of the Leiinae is discussed.

Fungus gnats represent an informal assemblage of insect families in the superfamily Sciaroidea. This is a highly diverse group comprising nearly 1000 species in Fennoscandia. Fungus gnats are comparatively well studied in the Republic of Karelia, although the coverage is uneven. Hence, any new data from poorly known areas would provide a better background for further analysis of zoogeographical patterns both at local and at Fennoscandian level. With just 100 known species, the fauna of fungus gnats in the Kostomuksha State Nature Reserve has until recently been insufficiently studied. The paper presents the results of faunistic research in the Kostomuksha State Nature Reserve since 1993. The revised checklist is based on original material and includes 177 species of fungus gnats belonging to the families Bolitophilidae, Diadocidiidae, Keroplatidae and Mycetophilidae. Eighty-five species were added to the fauna, and eight species were removed from the list. The revealed diversity is comparatively low and most of the recorded taxa are common in Fennoscandia. However, a number of rare and remarkable species was found, indicating a potentially rich fauna. Five species (Mycomya obliqua, Sciophila krysheni, Syntemna morosa, Mycetophila devioides, Mycetophila haruspica) are reported for the first time from the Republic of Karelia and Russia. Mycomya obliqua is also new for the Palaearctic region. All remarkable records are commented, and male genitalia images are provided for poorly known species. Two species of presumably western origin (Sciophila krysheni and Mycetophila devioides) and one Nearctic species (Mycomya obliqua) are discussed in more details. A relatively low diversity is explained by an insufficient earlier collecting activity and concentration of recent Malaise trapping on small islands with a poorer fauna. The need for further studies in the Kostomuksha State Nature Reserve, with a better coverage of habitats and using additional collecting methods, is substantiated.
