Various hypotheses have been proposed regarding the circumstances of their dispersal to the south. Some estimated their origin as relatively recent, with long-distance dispersal to the southern continents in the Late Cretaceous or early Paleogene. On the other hand, fossils of Notonemouridae have been dated to the Middle Jurassic, proving the lineage is very ancient. However, all known notonemourid fossils originate from Asia and the timing of their dispersal to the south cannot be precisely estimated. Here we report new fossil stoneflies from the Late Jurassic Talbragar Fish Beds, Australia, described as Talbragaria australis gen. et sp. nov. and attributed to Notonemouridae. This finding represents the first fossil evidence of the northern suborder Arctoperlaria in the Southern Hemisphere, and confirms the north-to-south dispersal of Notonemouridae across Pangea prior to the continental break-up.","PeriodicalId":55460,"journal":{"name":"Arthropod Systematics & Phylogeny","volume":"29 25","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134954649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In previous studies, this special feature can be one of the important features to distinguish and identify these crickets. But does this particular head shape truly reflect a clear-cut taxonomic relationship? The species of the genus Loxoblemmus have a typical truncate head; species of the genus Stephoblemmus have a more exaggerated truncate head, with the frontal end even extending into a lamellar. The genus Mitius is relatively unusual in that species of this genus have both globose or truncate heads. How are these species related? Does the cephalic shape perfectly reflect the natural classification of these species? Based on these questions, the study applied species definition and morphological classification to explore the intergeneric and intrageneric species relationships of the genera Mitius , Stephoblemmus , and Loxoblemmus , and derived the following main conclusions: (1) Mitius and Stephoblemmus are related and distinct from Loxoblemmus ; (2) Mitius species bear two types of frons (truncated and rounded), but this feature disallows them to be classified as natural groups; (3) one genus synonym and three species synonyms are raised ( Mitius Gorochov, 1985 syn. n. , Mitius splendens (Shiraki, 1930) syn. n. , Mitius eryuanensis Yuan, Xie & Liu, 2021 syn. n. and Mitius brevipennis Yuan, Ma & Gu, 2022 syn. n. ), and seven new status combinations are proposed ( Stephoblemmus blennus (Saussure, 1877) comb. n. , Stephoblemmus castaneus (Chopard, 1937) comb. n. , Stephoblemmus enatus Gorochov, 1994 comb. n. , Stephoblemmus flavipes (Chopard, 1928) comb. n. , Stephoblemmus minor (Shiraki, 1911) comb. n. , Stephoblemmus minutulus (Yang & Yang, 1995) comb. n. and Stephoblemmus vaturu (Otte & Cowper, 2007) comb. n. ).

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 family Panopeidae aligns with the family Xanthidae to form the Xanthoidea branch, which is supported by current morphological and genetic taxonomy. A unique gene arrangement termed ‘XanGO’ was identified for the panopeids and varies relative to other members of the subsection Heterotremata (within the Eubrachyura) via a transposition of the trnV gene. This gene arrangement is novel and is shared between several Xanthoidea species, including Etisus anaglyptus (hairy spooner crab), Atergatis floridus (brown egg crab), and Atergatis integerrimus (red egg crab), suggesting that it is a conserved gene arrangement within the Xanthoidea superfamily.

Here we review the Mesozoic fossil record of Sphindidae and report a new sphindid genus and species, Trematosphindus newtonigen. et sp. nov., from Albian/Cenomanian amber from northern Myanmar (ca. 99 Ma). Trematosphindus is set apart from all other sphindids by the presence of distinct lateral cavities on the anterior pronotal angles. Our phylogenetic analysis identifies Trematosphindus as an early-diverging genus within Sphindidae, sister to the remainder of the family except Protosphindus, or Protosphindus and Odontosphindus. The new fossils provide evidence that basal crown slime mold beetles begun to diversify by the mid-Cretaceous, providing a valuable calibration point for understanding timescale of sphindid co-evolution with slime molds.","PeriodicalId":55460,"journal":{"name":"Arthropod Systematics & Phylogeny","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46199114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
