<jats:title>Abstract</jats:title>
<jats:p>Diplurans are among the earliest hexapods in the geological record. These primitively wingless relatives of insects are infrequently encountered despite being pervasive in soil habitats. Two groups have disparate adaptations for hunting, one mechanical and the other chemical, in Japygoidea and Projapygoidea, respectively. Here, we report three genera (two new) and four species of fossil Projapygidae preserved in Mesozoic and Cenozoic ambers: Electroprojapyx alchemicus gen. et sp. nov. in mid-Cretaceous Myanmar amber, and Symphylurinopsis punctatus gen. et sp. nov. and two species (unnamed) of Symphylurinus in Miocene Dominican amber. The exceptionally preserved specimens possess cerci that are morphologically specialized for expelling a glandular substance on prey. The new Cretaceous E. alchemicus is a stem group to all living species of the family and provides conclusive Mesozoic evidence for a rare type of predation involving offensive (vs. defensive) secretions. The specimen was fossilized in a preying-and-spraying position with its presumptive meal, a Symphypleona springtail (Collembola), reflecting the behavioural predatory repertoire of modern relatives. Apart from one Cenozoic species, these rare specimens represent the only fossil record of the family Projapygidae. Our findings demonstrate that these basal hexapods were predators of small arthropods of ancient forest soils and enrich our understanding of palaeoecological associations and behavioural strategies paramount for the survival of species.</jats:p>

<jats:p>Termites, an economically significant group of eusocial cockroaches, are host to a variety of ectoparasitic fungi. Here, we provide up-to-date morphological and geographic data for fungal ectoparasites described belonging to the family Kathistaceae and describe Termitaria hexasporodochia sp. nov., a species observed to form lesions on its host in an unusual hexad arrangement. To date, the family Kathistaceae comprises 4 genera (Kathistes, Mattirolella, Termitaria, and Termitariopsis) and 11 valid species. Two genera we focus on in this paper, Termitaria and Mattirolella, are asexual ectoparasitic fungi that form sporodochia on the eusocial insects, termites. Morphological data collected via Micro-CT, SEM, and confocal microscopy confirms that this is a new fungal species belonging to the genus Termitaria. A comparison chart and dichotomous key are provided to distinguish all members of the family, Kathistaceae, to which the new species belongs. </jats:p>

<jats:p>Ricinulei Thorell, 1876 is an order of Arachnida currently represented in the New and Old Worlds by 103 living species. The order is also represented in the fossil record from the Carboniferous (ca. 305–319 Ma) and the Cretaceous (ca. 99 Ma) periods. In the present contribution, Hirsutisoma grimaldii sp. nov., a new extinct species of the suborder Primoricinulei Wunderlich, 2015, is described from a specimen preserved in Cretaceous Burmese amber. The specimen is a well-preserved adult male in which several taxonomically informative structures are visible, allowing the new species to be differentiated from Hirsutisoma bruckschi Wunderlich, 2017, the only other congener for which a male is known. This description raises the number of Cretaceous Ricinulei species to six. A comparative table documents morphological differences among the various species of this lineage. Hypotheses concerning the paleoecology and functional morphology of this species and, by extrapolation, other primoricinuleids, are presented. The evidence suggests that Primoricinulei were corticolous, scansorial predators.</jats:p>

<jats:p>Oxygen is an important and often limiting reagent of a firefly’s bioluminescent chemical reaction. Therefore, the development of the tracheal system and its subsequent modification to support the function of firefly light organs are key to understanding this process. We employ micro-CT scanning, 3D rendering, and confocal microscopy to assess the abdominal tracheal system in <jats:italic>Photinus pyralis</jats:italic> from the external spiracles to the light organ’s internal tracheal brush, a feature named here for the first time. The abdominal spiracles in firefly larvae and pupae are of the biforous type, with a filter apparatus and appear to have an occlusor muscle to restrict airflow. The first abdominal spiracle in the adult firefly is enlarged and bears an occlusor muscle, and abdominal spiracles two through eight are small, with a small atrium and bilobed closing apparatus. Internal tracheal system features, including various branches, trunks, and viscerals, were homologized across life stages. In adults, the sexually dimorphic elaboration and increase in volume associated with tracheal features of luminous segments emphasizes the importance of gas exchange during the bioluminescent process.</jats:p>

<jats:p>Among the many inclusions from the exceptionally rich fossiliferous amber of Zhangpu, China (Middle Miocene: Langhian), stingless bees (Apinae: Meliponini) are particularly common, analogous to the merely slightly older amber sites of Mexico and the Dominican Republic. While there is a large number of workers in Zhangpu amber, only two species are represented. The systematics and morphology of the tribe Meliponini is outlined, including a revision to terms of orientation and direction when discussing surfaces and features of appendages, all in order to better discuss the traits of the fossils as well as place them into a broader context in the global systematics of stingless bees. The two amber species are representative of two Old World genera of Meliponini: Tetragonula Moure and Austroplebeia Moure. While the former is widespread across southern Asia, Malesia, Papuasia, and Australia, the latter is today known only from New Guinea and Australia. Neither genus occurs in the environs of Zhangpu today. Tetragonula (Tetragonula) florilega Engel, new species, is a generally typical species of the subgenus although it intermingles traits otherwise found in two large species groups of non-Australian Tetragonula s.str. The species of Austroplebeia from Zhangpu is sufficiently distinct to place in a new subgenus, Anteplebeina Engel. Austroplebeia (Anteplebeina) fujianica Engel, new species, shares a long list of character states with Austroplebeia s.str., including the presence of yellow maculation on the face, mesoscutum, mesoscutellum, and metepisternum, found only in this clade among Asiatic Meliponini. Nonetheless, the species differs in the length of the malar space and various features of wing venation. Keys are provided to the genera in Zhangpu amber and the subgenera of both genera. The diversity of stingless bees in amber is discussed, as well as the presence of these two fossils in the Middle Miocene of mainland Asia in relation to prior divergence time estimates, phylogenetic relationships, as well as the paleogeography of the region and potential biogeographic hypotheses. The biological association of stingless bees with resins, particularly the collection of dipterocarp resins, is discussed as Zhangpu amber is a Class II resin likely produced by an extinct species of Dipterocarpaceae (Malvales). Also discussed are the ecological preferences of modern Tetragonula and Austroplebeia relative to the reconstructed paleoenvironment of the Zhangpu amber rainforest. Emendations to the classification of Meliponini are appended, with the following new taxa proposed: Atrichotrigona Engel, new subgenus of Axestotrigona Moure; Lispotrigona V.H. Gonzalez &amp; Engel, new subgenus of Nannotrigona Cockerell; Asperplebeia Engel, new genus; Nanoplebeia Engel, new subgenus of Plebeia Schwarz; Aphaneuropsis Engel, Koilotrigona Engel, Necrotrigona Engel, Dichrotrigona Engel, Nostotrigona Engel, Ktinotrofia Engel, all new subgenera of Trigona Jurine; Chapadapis Engel, new subgenus of Schwarziana Moure. The following higher groups are also established: Hypotrigonina Engel, new sutribe; Heterotrigonitae Engel, new infratribe; Trigoniscitae Engel, new infratribe.</jats:p>

<jats:p>The tribe Melikertini (Apinae: Corbiculata) is an extinct group of highly eusocial bees presently known only from early to late Eocene deposits of Eurasia. Among melikertine diversity are a suite of species peculiar for their rather dramatic morphological specializations, at least in relation to modern corbiculate Apinae. Here we document two new species of Melikertini and utilize standard X-ray as well as propagation phase contrast synchrotron computed microtomography to further explore these and previously known species, revealing finer details not previously observable from melikertines. Accordingly, some species placed in the genera Melikertes Engel and Succinapis Engel are reëvaluated. Three new genera are characterized, as well as some further facial modifications not previously known for the tribe. New taxa and taxonomic changes presented are: Aethemelikertes emunctorii Engel, new genus and species; Haidomelikertes uraeus Engel, new genus and species; H. proboscidea (Engel), new combination; Amelikertotes Engel, new genus; Amelikertotes clypeata (Engel), new combination. Additionally, new records and taxonomic notes on other Baltic amber and Eocene bees are appended, with the following nomenclatural changes established: Palaeomacropis Michez &amp; Nel is recognized as a megachiline rather than a melittid, and is transferred to Megachilinae where it is a new junior synonym of Ctenoplectrella Cockerell (new synonymy); Ctenoplectrella eocenica (Michez &amp; Nel), new combination; a key is provided to species of Ctenoplectrella; Thaumastobombina Engel, new subtribe in Electrapini; Thnetobombus Engel, new subgenus in Protobombus Cockerell; Mesomelissa Engel, new subgenus in Electrapis Cockerell; Electrapis (Euglossopteryx) biesmeijeri (De Meulemeester et al.), new combination.  A list of Eocene bees is appended.</jats:p>

<jats:title>ABSTRACT</jats:title>
<jats:p>Genes known to affect circadian rhythms (i.e. ‘clock genes’) also influence the photoperiodic induction of overwintering reproductive diapause in the northern house mosquito, Culex pipiens f. pipiens. This suggests that molecular changes in one or more clock genes could contribute to the inability to diapause in a second form of this mosquito, Culex pipiens f. molestus. Temperate populations of Cx. pipiens f. molestus inhabit underground locations generally devoid of predictable photoperiods. For this reason, there could be limited fitness consequences if the hypothesized molecular changes to its clock genes also eliminated this mosquito's ability to regulate circadian rhythms in response to photoperiod variation. Here, we demonstrate that in contrast to this prediction, underground derived Cx. pipiens f. molestus retain exogenously influenceable circadian rhythms. Nonetheless, our genetic analyses indicate that the gene Helicase domino (dom) has a nine-nucleotide, in-frame deletion specific to Cx. pipiens f. molestus. Previous work has shown that splice variants in this gene differentially influence circadian behavior in Drosophila melanogaster. We also find derived, non-synonymous single nucleotide polymorphisms (SNPs) in eight genes that may also affect circadian rhythms and/or diapause induction in Cx. pipiens f. molestus. Finally, four putative circadian genes were found to have no quantifiable expression during any examined life stage, suggesting potential regulatory effects. Collectively, our findings indicate that the distinct, but molecularly interconnected life-history traits of diapause induction and circadian rhythms are decoupled in Cx. pipiens f. molestus and suggest this taxon may be a valuable tool for exploring exogenously influenced phenotypes in mosquitoes more broadly.</jats:p>

<jats:title>Abstract</jats:title><jats:sec>
<jats:title>Background</jats:title>
<jats:p>Within the <jats:italic>Culex pipiens</jats:italic> mosquito complex, there are six contemporarily recognized taxa: <jats:italic>Cx</jats:italic>. <jats:italic>quinquefasciatus</jats:italic>, <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>pipiens</jats:italic>, <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>molestus</jats:italic>, <jats:italic>Cx</jats:italic>. <jats:italic>pipiens pallens</jats:italic>, <jats:italic>Cx</jats:italic>. <jats:italic>australicus</jats:italic> and <jats:italic>Cx</jats:italic>. <jats:italic>globocoxitus</jats:italic>. Many phylogenetic aspects within this complex have eluded resolution, such as the relationship of the two Australian endemic taxa to the other four members, as well as the evolutionary origins and taxonomic status of <jats:italic>Cx</jats:italic>. <jats:italic>pipiens pallens</jats:italic> and <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>molestus</jats:italic>. Ultimately, insights into lineage relationships within the complex will facilitate a better understanding of differential disease transmission by these mosquitoes. To this end, we have combined publicly available data with our own sequencing efforts to examine these questions.</jats:p>
</jats:sec><jats:sec>
<jats:title>Results</jats:title>
<jats:p>We found that the two Australian endemic complex members, <jats:italic>Cx</jats:italic>. <jats:italic>australicus</jats:italic> and <jats:italic>Cx</jats:italic>. <jats:italic>globocoxitus</jats:italic>, comprise a monophyletic group, are genetically distinct, and are most closely related to the cosmopolitan <jats:italic>Cx</jats:italic>. <jats:italic>quinquefasciatus</jats:italic>. Our results also show that <jats:italic>Cx</jats:italic>. <jats:italic>pipiens pallens</jats:italic> is genetically distinct, but may have arisen from past hybridization. Lastly, we observed complicated patterns of genetic differentiation within and between <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>pipiens</jats:italic> and <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>molestus</jats:italic>.</jats:p>
</jats:sec><jats:sec>
<jats:title>Conclusions</jats:title>
<jats:p>Two Australian endemic <jats:italic>Culex</jats:italic> taxa, <jats:italic>Cx</jats:italic>. <jats:italic>australicus</jats:italic> and <jats:italic>Cx</jats:italic>. <jats:italic>globocoxitus</jats:italic>, belong within the <jats:italic>Cx. pipiens</jats:italic> complex, but have a relatively older evolutionary origin. They likely diverged from <jats:italic>Cx</jats:italic>. <jats:italic>quinquefasciatus</jats:italic> after its colonization of Australia. The taxon <jats:italic>Cx</jats:italic>. <jats:italic>pipiens pallens</jats:italic> is a distinct evolutionary entity that likely arose from past hybridization between <jats:italic>Cx</jats:italic>. <jats:italic>quinquefasciatus</jats:italic> and <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>pipiens</jats:italic>/<jats:italic>Cx. pipiens</jats:italic> f. <jats:italic>molestus</jats:italic>. Our results do not suggest it derives from ongoing hybridization. Finally, genetic differentiation within the <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>pipiens</jats:italic> and <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>molestus</jats:italic> samples suggests that they collectively form two separate geographic clades, one in North America and one in Europe and the Mediterranean. This may indicate that the <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>molestus</jats:italic> form has two distinct origins, arising from <jats:italic>Cx</jats:italic>. <jats:italic>pipiens</jats:italic> f. <jats:italic>pipiens</jats:italic> in each region. However, ongoing genetic exchange within and between these taxa have obscured their evolutionary histories, and could also explain the absence of monophyly among our samples. Overall, this work suggests many avenues that warrant further investigation.</jats:p>

<jats:p>Etheophanus Broun is considered a molytine based on the form of the pharyngeal plate, presence of a small spiculum relictum in the male, and presence of a pair of small internal apodemes on the antero-lateral corners of the 5th abdominal ventrite of the female. Examination of primary type specimens and newer material confirm one new species Etheophanus kuscheli sp. n. and two synonomies (Etheophanus nitidellus Broun, 1923 [= Etheophanus obscurus Broun, 1923] and Etheophanus striatus Broun, 1910 [=Etheophanus punctiventris Broun, 1914]). Generic and species diagnoses, a key to the species, and lectotype designations for three species are included. Phylogenetic reconstructions based on a combined analysis of the nuclear 28S rRNA and mitochondrial cytochrome c oxidase subunit I genes confirmed the status of E. kuscheli and a species complex, the E. nitidellus/E. optandus clade distributed in the southern portion of the South Island. The relationship E. pinguis [northern North Island] (E. striatus [southern North Island, northern South Island] (E. kuscheli [northwestern South Island] (E. nitidellus, E. optandus [southwestern North Island]) corresponds to geographic patterns found in other beetle lineages. Etheophanus striatus is composed of three lineages, one widespread in the north and south islands and two allopatric populations in the northwest South Island. The E. nitidellus/E. optandus complex includes four distinct lineages, one restricted to Fiordland, the other three sympatric in the region affected by the Haast Corridor. </jats:p>

<jats:p>The 2016 International Weevil Meeting was held immediately after the International Congress of Entomology (ICE). It built on the topics and content of the 2016 ICE weevil symposium Phylogeny and Evolution of Weevils (Coleoptera: Curculionoidea): A Symposium in Honor of Dr. Guillermo "Willy” Kuschel. Beyond catalyzing research and collaboration, the meeting was intended to serve as a forum for identifying priorities and goals for those who study weevils. The meeting consisted of 46 invited and contributed lectures, discussion sessions and introductory remarks presented by 23 speakers along with eight contributed research posters. These were organized into three convened sessions, each lasting one day: (1) weevil morphology; (2) weevil fossils, biogeography and host/habitat associations; and (3) molecular phylogenetics and classification of weevils. Some of the topics covered included the 1K Weevils Project, major morphological character systems of adult and larval weevils, weevil morphological terminology, prospects for future morphological character discovery, phylogenetic analysis of morphological character data, the current status of weevil molecular phylogenetics and evolution, resources available for phylogenetic and comparative genomic studies of weevils, the weevil fossil record, weevil biogeography and evolution, weevil host plants, evolutionary development of the weevil rostrum, resources available for weevil identification and the current status of and challenges in weevil classification.</jats:p>

<jats:p>Among weevils of the subfamily Baridinae (548 extant genera and ca. 9,000 species), unique prosternal horns and associated sheaths have evolved independently multiple times. These structures are utilized in a unique form of male-male aggression in which males push, rather than overturn as in most other horned beetles, their competitor. Herein we report the first fossils of male Baridinae exhibiting such prosternal horns. Two males recovered from the middle Eocene Green River Formation in northwestern Colorado serve to provide a minimum age (at ca. 47 million years old) for both the origin of horns and its associated form of male-male combat in Baridinae.</jats:p>
