The holotypes of<em> Plesioblattogryllus magnificus</em> and <em>Duoduo qianae</em> are examined and new synonymies are proposed: <em>Plesioblattogryllus </em>Huang, Nel &amp; Petrulevičius, 2008 =<em> Duoduo </em>Cui, 2012, <strong>syn. nov.</strong>; <em>Plesioblattogryllus magnificus</em> Huang, Nel &amp; Petrulevičius, 2008 =<em> Duoduo qianae</em> Cui, 2012, <strong>syn. nov.</strong> The holotype of <em>Plesioblattogryllus minor</em> Ren &amp; 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 <em>P. magnificus</em> 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, <em>Aristoviblattogryllus</em> <strong>gen. nov.</strong>, to accommodate the species <em>Aristoviblattogryllus minor</em> (Ren &amp; Aristov, 2011), <strong>comb. nov.</strong></p> YINGYING CUI OLIVIER BÉTHOUX NAN YANG DONG REN Copyright (c) 2023 Magnolia press limited 2023-04-28 2023-04-28 6 2 124–132 124–132 10.11646/palaeoentomology.6.2.4 <p><strong>New taxa of Sepulcidae (Hymenoptera) from mid-Cretaceous Kachin amber</strong></p> <p>Three new species of the genus <em>Prosyntexis</em> Sharkey, 1990 in the extinct sawfly family Sepulcidae, <em>Prosyntexis aristovi</em> <strong>sp. nov.</strong>, <em>P</em>. <em>lata </em><strong>sp. nov. </strong>and <em>P. antennata </em><strong>sp. nov.</strong>, are described from five well-preserved specimens from the mid-Cretaceous Kachin amber. These new species, the first records of the family Sepulcidae in Kachin amber, are placed in <em>Prosyntexis</em> (Trematothoracinae) based on the mesonotum membranous centrally with sides ridge transversely; forewing with the basally arched M+Cu; basal third or half of costal space narrowed; and 2r-m absent. The conspecific male and female of <em>Prosyntexis lata</em> with well-preserved genitalia are reported for the first time in the family Sepulcidae. A key to fossil species of <em>Prosyntexis </em>is provided. These new findings improve our understanding of <em>Prosyntexis</em> by adding more morphological features, such as antenna with no fewer than 16 segments, basal and distal hamuli present, tibia apical spurs 1-2-2, etc. The new taxa suggest that the Sepulcidae should range in age from at least from the Middle Jurassic to the mid-Cretaceous.</p> XIAO-QIN LI ALEXANDR P.

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.</p> MARÍA B.

(</strong>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 <em>incertae sedis</em> 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.</p> ALEXANDER A.

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 <strong>fam. nov.</strong> 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.</p> SERGEY YU.

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 <em>Notocupes</em> and of taxonomic issues associated with this species-rich genus is compiled. Several morphological characters useful for identification are discussed in detail, <em>viz</em>., body tubercles and their distribution on the body, main and intercalary elytral veins and pronotal shape.</p> OLESYA D.

This systematic change is supported by the crucial presence <em>vs</em>. absence of tarsal arolia. We also synonymize the monotypic genus <em>Duoduo</em> Cui, 2012 <strong>syn. nov.</strong> under <em>Plesioblattogryllus</em> Huang <em>et al.,</em> 2008 and transfer it to the Plesioblattogryllidae, we transfer its type species <em>Duoduo</em> <em>qianae</em> to the genus <em>Plesioblattogryllus</em>.

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: <em>Daniilacheta aristovi</em> <strong>gen. et sp. nov.</strong> (Protogryllinae) and <em>Plesioschwinzia sharovi</em> <strong>sp. nov.</strong> (Locustopsinae). Some additional species, previously attributed to <em>Locustopsis</em> Handlirsch, are tentatively included in <em>Plesioschwinzia</em> Zessin. New specimens, possibly belonging to <em>Locustopsis spectabilis</em> Zeuner, are briefly described and illustrated.</p> ANDREI V. GOROCHOV ROBERT A.

It belongs to a typical Triassic genus, <em>Ideliopsina </em>Storozhenko, 1996, which species have been previously reported from the Kyrgyz Republic and the Kazakhstan in Central Asia. The new species shows that the corresponding family, the Ideliidae ranging from the Cisuralian to the Late Triassic, remained widely distributed during the latter period, before its extinction.</p> NOZOMU OYAMA KENJI SHINODA HUMIO TAKAHASHI EIJI DOI OLIVIER BÉTHOUX Copyright (c) 2023 Magnolia press limited 2023-04-28 2023-04-28 6 2 205–213 205–213 10.11646/palaeoentomology.6.2.12 <p><strong><em>Plectrocnemia aristovi</em> sp. nov., a new fossil species of Polycentropodidae (Insecta: Trichoptera) from Eocene Rovno amber</strong></p> <p>Forty-five species of caddisflies are known from Rovno amber (Ivanov <em>et al</em>., 2016; Perkovsky, 2017; Melnitsky <em>et al</em>., 2021a–c). The new 24 caddisfly species from 8 families (Psychomyiidae – 1, Polycentropodidae – 11, Ecnomidae – 2, Philopotamidae – 2,&nbsp; Hydroptilidae – 4, Phryganeidae – 1, Lepidostomatidae – 1, Leptoceridae – 3) of Rovno amber are described in recent papers of last decade (Melnitsky &amp; Ivanov, 2010, 2013, 2016 a, b; Melnitsky <em>et al</em>., 2021a–c). The family Polycentropodidae includes more than 910 species in the world fauna, of which about 100 are fossils (Morse, 2023). The genus <em>Plectrocnemia</em> contains over 160 species; representatives of this genus are widespread in the Holarctic and Oriental realms. The genus <em>Plectrocnemia</em> is represented by 27 fossil species in the Paleogene resins of Europe, five of which are noted in Rovno amber (Melnitsky <em>et al</em>., 2021a). Three species: <em>Plectrocnemia nastigermania</em> Melnitsky &amp; Ivanov, 2013, <em>Plectrocnemia ucrainum</em> Melnitsky &amp; Ivanov, 2013, and <em>Plectrocnemia kirmikhia</em> Melnitsky, Ivanov &amp; Perkovsky, 2021 are endemic to Rovno amber.
