The journal Palaeoentomology was founded in late 2018 through a collaboration between the International Palaeoentomological Society (IPS) and Magnolia Press (the publisher of Zootaxa) in response to an exponential growth in the number of papers in this field (Azar et al., 2018). This specialized journal aims to be a high-quality platform for bringing together recent research and discoveries in fossil insects and other terrestrial arthropods, as well as other amber inclusions (Azar et al., 2018). The new journal has been warmly welcomed by the palaeoentomological community and sustained stable development in the first five years (2018–2022). In November 2022, Palaeoentomology was accepted by Clarivate for coverage in the Emerging Sources Citation Index™ (ESCI) in the Web of Science Core Collection™, and is expected to have its first journal impact factor in mid-June 2023. All papers published during 2018–2022 in Palaeoentomology were indexed in ESCI in January 2023. Here, I provide a summary of the first five volumes of this journal, with focus on citation patterns as well as an estimate of its first Journal Impact Factor™.
《古昆虫学》杂志成立于2018年底，由国际古昆虫学会（IPS）和Magnolia出版社（动物分类群的出版商）合作，以应对该领域论文数量的指数增长（Azar等人，2018）。这本专业期刊旨在成为一个高质量的平台，汇集昆虫化石和其他陆生节肢动物以及其他琥珀内含物的最新研究和发现（Azar等人，2018）。该新期刊受到了古昆虫学界的热烈欢迎，并在前五年（2018-2022）持续稳定发展。2022年11月，古昆虫学被Clarivate纳入新兴资源引文索引™ （ESCI）在Web of Science核心收藏中™, 预计将于2023年6月中旬发布首个期刊影响因子。2018-2022年发表在《古昆虫学》上的所有论文均于2023年1月在ESCI中编入索引。在这里，我提供了本期刊前五卷的摘要，重点是引文模式以及对其第一期期刊影响因子的估计™.

Four Triassic species of the ommatid beetles Notocupes are redescribed using an extended list of diagnostic characters from both published sources and original study. New diagnoses for the genus as well as for four Triassic species are provided with emphasis on discrete characters of cuticular sculpture and elytral venation. A brief overview of research history of Notocupes and of taxonomic issues associated with this species-rich genus is compiled. Several morphological characters useful for identification are discussed in detail, viz., body tubercles and their distribution on the body, main and intercalary elytral veins and pronotal shape.

A new scytinopterid (Hemiptera: Cicadomorpha), Duraznoscytinum aristovi gen. et sp. nov., is described. The specimen was recovered from the upper section of the Potrerillos Formation (Upper Triassic) at the Quebrada del Durazno locality, south of the Cerro Cacheuta, Cuyana Basin, in Mendoza, Argentina. This represents the first record of a complete forewing (tegminous + clavus) of a scytinopterid for the Triassic of South America. Additionally, we briefly discuss the Triassic scytinopterid distribution worldwide, and provide preliminary morphological differences observed between the taxa recorded in the Southern Hemisphere. The new fossil described herein contributes to the knowledge on the hemipterofauna diversity present at the south of the Cerro Cacheuta area during Early Mesozoic times.

The new grylloblattid family Aristoviidae Storozhenko & Gröhn fam. nov., with the type genus and species Aristovia daniili Storozhenko & Gröhn gen. et sp. nov., is described from the lowermost Cenomanian amber (Hukawng Valley, Kachin State, northern Myanmar). The new family is similar to the Permian-Triassic family Megakhosaridae and the Permian-Jurassic Blattogryllidae but differs from both by the shape of pronotum and wing venation. Aristoviidae fam. nov. is also similar to the extant family Grylloblattidae in body structure, but can easily be distinguished from it by the presence of ocelli, large compound eyes and wings, as well as the lack of the transverse furrow which separates the anterior part of pronotum from its posterior part. The phylogenetic relationships between families Megakhosaridae, Blattogryllidae, Grylloblattidae, and a new family are briefly discussed.

New material of Orthoptera from the Upper Triassic and Lower Jurassic of England is considered. Some problems with generic composition and diagnostics of the subfamily Protogryllinae (Protogryllidae) from the suborder Ensifera and of the subfamily Locustopsinae (Locustopsidae) from the suborder Caelifera are discussed. One new genus and two new species are described: Daniilacheta aristovi gen. et sp. nov. (Protogryllinae) and Plesioschwinzia sharovi sp. nov. (Locustopsinae). Some additional species, previously attributed to Locustopsis Handlirsch, are tentatively included in Plesioschwinzia Zessin. New specimens, possibly belonging to Locustopsis spectabilis Zeuner, are briefly described and illustrated.

Forty-five species of caddisflies are known from Rovno amber (Ivanov et al., 2016; Perkovsky, 2017; Melnitsky et al., 2021a–c). The new 24 caddisfly species from 8 families (Psychomyiidae – 1, Polycentropodidae – 11, Ecnomidae – 2, Philopotamidae – 2, Hydroptilidae – 4, Phryganeidae – 1, Lepidostomatidae – 1, Leptoceridae – 3) of Rovno amber are described in recent papers of last decade (Melnitsky & Ivanov, 2010, 2013, 2016 a, b; Melnitsky et al., 2021a–c). The family Polycentropodidae includes more than 910 species in the world fauna, of which about 100 are fossils (Morse, 2023). The genus Plectrocnemia contains over 160 species; representatives of this genus are widespread in the Holarctic and Oriental realms. The genus Plectrocnemia is represented by 27 fossil species in the Paleogene resins of Europe, five of which are noted in Rovno amber (Melnitsky et al., 2021a). Three species: Plectrocnemia nastigermania Melnitsky & Ivanov, 2013, Plectrocnemia ucrainum Melnitsky & Ivanov, 2013, and Plectrocnemia kirmikhia Melnitsky, Ivanov & Perkovsky, 2021 are endemic to Rovno amber. Here we describe a new species from the genus Plectrocnemia from the Rovno amber.

The oldest unquestionable fishfly, Izyumochauliodes aristovi gen. et sp. nov. (Corydalidae, Chauliodinae), is described based on several larval fossils from the Upper Triassic Garazhovka locality in eastern Ukraine (Seversky Donets River basin, Kharkiv Region). The new genus with a typical Chauliodinae structure of the abdomen is distinguished from all other genera of the subfamily by having the occipital suture ventrally directed forward along the gula and reaching the submentum, and by the shape of mandibula with evenly curved inner margin, both characters similar to Sialidae. Another, poorly preserved larva, found in the same locality, is attributed to Sialidae incertae sedis and also represents the oldest record of the family. The co-occurrence of fossil larvae of both known families in the same locality is the palaeontological evidence for the Triassic divergence of the extant megalopteran lineages.

The systematics of the Blattogryllopterida (Grylloblattida) from the Jurassic Daohugou locality (China) is reconsidered. The holotypes of Plesioblattogryllus magnificus and Duoduo qianae are examined and new synonymies are proposed: Plesioblattogryllus Huang, Nel & Petrulevičius, 2008 = Duoduo Cui, 2012, syn. nov.; Plesioblattogryllus magnificus Huang, Nel & Petrulevičius, 2008 = Duoduo qianae Cui, 2012, syn. nov. The holotype of Plesioblattogryllus minor Ren & Aristov, 2011 is reinvestigated and re-documented, and a new well-preserved single wing of this rare species, also uncovered from the Jurassic Daohugou locality, is described. Besides the holotype, it is the first specimen exhibiting well-exposed wing venation characters for the species. Particular characters, such as the desclerotised MP, are better observed and complemented by Reflectance Transforming Imaging documentation. The new specimen might be a hind wing with a reduced plicatum, a trait yet unknown in grylloblattids. Based on these new data it occurs that, in contrast to P. magnificus and most Blattogryllopterida, the species possesses a long RP+MA fusion, with a long basal free part of MA and a very short basal free section of RP. Together with other characters, it justifies the erection of new genus, Aristoviblattogryllus gen. nov., to accommodate the species Aristoviblattogryllus minor (Ren & Aristov, 2011), comb. nov.
重新研究了侏罗纪道湖沟地区的小叶藻目(Grylloblattida)的系统分类。对Plesioblattogryllus magnificus和Duoduo qianae的全型进行了研究，并提出了新的同义词:Plesioblattogryllus Huang, Nel & petruleviius, 2008 = Duoduo Cui, 2012, syn11 .;本文对Plesioblattogryllus magnificus Huang, Nel & petrulevi， 2008 = Duoduo qianae Cui, 2012, syn11 .对Plesioblattogryllus minor Ren & Aristov, 2011的全型进行了重新调查和记录，并描述了侏罗纪道湖沟地区发现的这一稀有物种的一个保存完好的新单翼。它是该物种中第一个显示出充分暴露的翼脉特征的标本。特殊的特征，如去硬化的MP，可以通过反射变换成像文件更好地观察和补充。新发现的标本可能是后翅，皱褶减少，这一特征在灰瓢虫中尚不清楚。根据这些新的数据，我们发现，与黄花瓢虫和大多数bltogryllopterida相比，该物种具有较长的RP+MA融合，MA的基部自由部分很长，RP的基部自由部分很短。与其他性状一起，它证明了新属Aristoviblattogryllus gen. nov.的建立，以容纳Aristoviblattogryllus minor (Ren & Aristov, 2011)， comb。11月。

The holotypes of Plesioblattogryllus magnificus and Duoduo qianae are examined and new synonymies are proposed: Plesioblattogryllus Huang, Nel & Petrulevičius, 2008 = Duoduo Cui, 2012, syn. nov.; Plesioblattogryllus magnificus Huang, Nel & Petrulevičius, 2008 = Duoduo qianae Cui, 2012, syn. nov. The holotype of Plesioblattogryllus minor Ren & Aristov, 2011 is reinvestigated and re-documented, and a new well-preserved single wing of this rare species, also uncovered from the Jurassic Daohugou locality, is described. Besides the holotype, it is the first specimen exhibiting well-exposed wing venation characters for the species. Particular characters, such as the desclerotised MP, are better observed and complemented by Reflectance Transforming Imaging documentation. The new specimen might be a hind wing with a reduced plicatum, a trait yet unknown in grylloblattids. Based on these new data it occurs that, in contrast to P. magnificus and most Blattogryllopterida, the species possesses a long RP+MA fusion, with a long basal free part of MA and a very short basal free section of RP. Together with other characters, it justifies the erection of new genus, Aristoviblattogryllus gen. nov., to accommodate the species Aristoviblattogryllus minor (Ren & Aristov, 2011), comb. nov.","PeriodicalId":53179,"journal":{"name":"Palaeoentomology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46479830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
