A new protopristocerine wasp (Hymenoptera: Bethylidae) from the mid-Cretaceous Burmese amber

Ramageoptera platycephala gen. et sp. nov., a new protopristocerine wasp, is described and figured from a female individual preserved in mid-Cretaceous amber from Tanai, northern Myanmar. Ramageoptera platycephala gen. et sp. nov. shows most of the known characters used to circumscribe the extinct subfamily Protopristocerinae, and highlights the putative status of stem-Pristocerinae that may occupy the Protopristocerinae. Ramageoptera platycephala gen. et sp. nov. is unique among the Protopristocerinae, at least, for possessing a flat and square shaped head; eyes glabrous and small; mandibles with four conspicuous sharp teeth; antenna with short scape; forewing with Rs + M vein absent; vein M straight; cell 2R1 distally opened; cell 1Cu closed, sub-equal to R cell; cell 2Cu open.     

First gall midges (Diptera,Cecidomyioidea) from Late Cretaceous amber of the Taimyr Peninsula

Gall midges from Santonian amber of Yantardakh (Taimyr Peninsula) are investigated for the first time. Eight new genera and eight new species belonging to five tribes of the subfamily Micromyinae (Lestremiidae) are described. These are Caputmunda yantardakhica gen. et sp. nov. (Catochini), Cretoperomyia taimyrica gen. et sp. nov. (Peromyiini), Palaeostrobliella dmitrii gen. et sp. nov., Yantardakhiella pusilla gen. et sp. nov., and Zherikhiniella pedicellata gen. et sp. nov. (Strobliellini), Menssana norilsk gen. et sp. nov. (Micromyini), and Cretomycophila ekaterinae gen. et sp. nov., and Corporesana khatanga gen. et sp. nov. (Aprionini). A representative of Porricondylinae (Cecidomyiidae, Porricondylinae, Holoneurini) is recorded. The diagnoses based on morphometric parameters of tribes and previously established genera are emended. The species composition of gall midges from three Cretaceous amber faunas of different ages are analyzed.     

New and revised maimetshid wasps from Cretaceous ambers (Hymenoptera, Maimetshidae)

New material of the wasp family Maimetshidae (Apocrita) is presented from four Cretaceous amber deposits - the Neocomian of Lebanon, the Early Albian of Spain, the latest Albian/earliest Cenomanian of France, and the Campanian of Canada. The new record from Canadian Cretaceous amber extends the temporal and paleogeographical range of the family. New material from France is assignable to Guyotemaimetsha enigmatica Perrichot et al. including the first females for the species, while a series of males and females from Spain are described and figured as Iberomaimetsha Ortega-Blanco, Perrichot & Engel, gen. n., with the two new species Iberomaimetsha rasnitsyni Ortega-Blanco, Perrichot & Engel, sp. n. and Iberomaimetsha nihtmara Ortega-Blanco, Delclòs & Engel, sp. n.; a single female from Lebanon is described and figured as Ahiromaimetsha najlae Perrichot, Azar, Nel & Engel, gen. et sp. n., and a single male from Canada is described and figured as Ahstemiam cellula McKellar & Engel, gen. et sp. n. The taxa are compared with other maimetshids, a key to genera and species is given, and brief comments made on the family.     

A new anaxyelid wood wasp (Hymenoptera: ‘Symphyta’) from the mid-Cretaceous Burmese amber

A new genus and species of anaxyelid wasp is described and figured from the mid-Cretaceous Burmese amber as Curvitexis kopylovi gen. et sp. nov. The placement of this new genus within the Anaxyelidae is corroborated by its wing venation and the configuration of its mesosoma. This new genus differs from all other Syntexinae from the mid-Cretaceous Burmese amber biota, inter alia, owing to its forewing with the vein 1Rs curved and longer than 1M, the crossvein 1r-rs absent, the vein 2Rs + M present; the hind wing with the abscissa 2M + Cu present, the vein m-cu absent, and the cell r closed. The recently described Paraxiphydria resinata Gao et al., 2022 is transferred to Anaxyelidae: Syntexinae, and the subfamily Paraxiphydriinae Gao et al., 2022 is synonymized under Syntexinae.     

New Genera and Species of Psychodoid Flies from the Lower Cretaceous Amber Lebanon

Until now, only two Psychodoidea were known from Lebanese amber. We describe two new genera and species of Phlebotomidae ( Mesophlebotomites hennigi gen. et sp. nov., Libanophlebotomus lutfallahi gen. et sp. nov.) and four new genera with six new species of Psychodidae ( Paleopsychoda solignaci gen. et sp. nov., Paleopsychoda jacquelinae sp. nov., Protopsychoda nadiae gen. et sp. nov., Protopsychoda hammanaensis sp. nov., Libanopsychoda abillamai gen. et sp. nov., Cretapsychoda inexpectata gen. et sp. nov.) from the Lower Cretaceous amber of Hammana/Mdeirij, Lebanon. These fossils are included in a phylogenetic analysis of the subfamilies of Psychodoidea. This superfamily was probably as diverse in the Early Cretaceous as now.

New gall midge taxa of the subfamilies porricondylinae and lasiopterinae (Diptera,Cecidomyiidae) from the Rovno amber

Five new gall midge taxa of the subfamilies Porricondylinae and Lasiopterinae are described from the Late Eocene Rovno amber: Adsumyia integra gen. et sp. nov. (Dicerurini), Gratomyia inexigentis gen. et sp. nov. (Holoneurini), Winnertzia recusata sp. nov. (Winnertziini), Kovaleviola injusta gen. et sp. nov., and Spungisiola insuperabilis gen. et sp. nov. (Brachineurini).     

A new genus and species of the cockroach family Blattulidae from Lebanese amber (Dictyoptera,Blattina)

A new genus and species of the cockroach family Blattulidae, Ocelloblattula ponomarenkoi gen. et sp. nov., are described from the Early Cretaceous Lebanese amber. In the wing venation, the new genus is extremely similar to the Jurassic genus Blattula Handlirsch, differing from the latter in a number of characters in its body structure. This find reveals much about the body structure of the extinct family Blattulidae, which is related to ancestors of the suborders Mantina and Blattina.     

New and little known orthopteroid insects (polyneoptera) from fossil resins: Communication 2

New taxa of the suborder Blattina (order Dictyoptera), possibly belonging to the family Corydiidae (Erucoblatta semicaeca gen. et sp. nov., Miocene; Proholocompsa gen. nov., Eocene; and Holocompsa nigra sp. nov. and H. abbreviata sp. nov., Miocene) and belonging to the family Ectobiidae (Plectoptera electrina sp. nov., Miocene; Agrabtoblatta symmetrica gen. et sp. nov. and ?Symploce rete sp. nov., Pleistocene) are described. The taxonomic position of the enigmatic genus Raphidiomimula Grimaldi et Ross from the Upper Cretaceous is discussed.     

A new trogiid genus from lower Eocene Fushun amber (Insecta: Psocodea: Trogiomorpha)

A new fossil brachypterous psocid tax on belonging to the family Trogiidae is characterized, illustrated and described from the early Eocene Fushun amber. Paralepinotus fushunensis nov. gen., nov. sp., shares several characters with the genus Lepinotus von Heyden, 1850, but differs from it mainly by the presence of tibial spurs other than apical ones and the absence of a forked sensillum on the last maxillary palp. This fossil taxon is also characterized by relatively developed elytriform forewing but still not reaching the tip of the abdomen. A checklist of all known Trogiidae is provided.     

New gall midges of the subfamily Lestremiinae (Diptera, Cecidomyiidae) from the Rovno amber

Two new genera and eight new species of the gall midges subfamily Lestremiinae, viz. Berestella insuperabilis gen. et sp. nov., Monardia impellucida sp. nov., Xylopriona aristata sp. nov. (Micromyini), Aprionus improvisus sp. nov., A.? vlaskini sp. nov. (Aprionini), Vicemyia immediata gen. et sp. nov. (Peromyiini), Cordylomyia cauta sp. nov. (Campylomyzini) and Bryomyia necessaria sp. nov. (Bryomyiini) from the Late Eocene Rovno amber are described. New combinations, i.e., Cordylomyia declinata (Fedotova, 2004), comb. nov. and Cordylomyia magnifica (Nel et Prokop, 2006), comb. nov. (both are transferred from Neurolyga) are proposed. No species in common with the fauna from the Baltic amber are recorded.     

New and little known orthopteroid insects (Polyneoptera) from fossil resins: Communication 3

New taxa of Orthoptera Ensifera are described in the families Mogoplistidae [Protomogoplistes asquamosus gen. et sp. nov. (Upper Cretaceous) in the subfamily Protomogoplistinae subfam. nov. and Archornebius balticus gen. et sp. nov. (Eocene), Pseudarachnocephalus gen. nov., P. dominicanus sp. nov., and P. latiusculus sp. nov. (all Miocene) in Mogoplistinae] and Gryllidae [Eopentacentrus borealis gen. et sp. nov. (Eocene), ?Grossoxipha feminea sp. nov. (Miocene), and Apentacentrus copalicus sp. nov. in the subfamily Pentacentrinae, ?Cyrtoxipha electrina sp. nov. and ?Cyrtoxipha illegibilis sp. nov. (both Miocene) in Trigonidiinae, and Baltonemobius fossilis gen. et sp. nov. (Eocene) in Nemobiinae]. The Miocene genera Proanaxipha Vickery et Poinar and Grossoxipha Vickery et Poinar are transferred from the subfamily Trigonidiinae to Pentacentrinae. P. latoca Vickery et Poinar and Abanaxipha longispina Vickery et Poinar are redescribed; the male of the latter species is described for the first time.     

Larvae of caddisflies (Insecta: Trichoptera) from the Mesozoic of Siberia

Body fossils of caddisfly larvae are described for the first time based on material from the Lower Cretaceous of Siberia (Baissa locality, Neocomian). The material includes a fully grown larva of Baissoplectrum separatum gen. et sp. nov. (Brachycentridae), Creterotesis coprolithica gen. et sp. nov. (Leptoceridae), and Cretolype minuta gen. et sp. nov., a tiny larva probably belonging to an uncertain family of the suborder Annulipalpia (Hydropsychina). C. coprolithica built unusually soft larval cases of pellets; these cases are described as a separate new indusigenus and indusispecies Coprindusia pallida gen. et sp. nov. Bionomics, taxonomy, and evolution of the Mesozoic larvae of Trichoptera are discussed.     

New acrodont lizards (Lacertilia) from the Middle Eocene of southern Mongolia

The problematic lizard family Changjiangosauridae, representatives of which inhabited Asia in the Early Paleogene, is discussed. Six new species of this group, including Acrodontopsis robustus gen. et sp. nov., Agamimus gracilis gen. et sp. nov., Graminisaurus interruptus gen. et sp. nov., Khaichinsaurus reshetovi gen. et sp. nov., Lavatisaurus elegans gen. et sp. nov., and Lentisaurus giganteus gen. et sp. nov., from the Middle Eocene of the Khaichin Uul 2 locality (southern Gobi, Mongolia) are described. It is shown that Changjiangosauridae are probably related to the Late Cretaceous Isodontosauridae and recent Uromastycidae; independent development of a number of dental features in different lineages of Acrodonta (Iguania) is corroborated.     

New archaeocynipids (Hymenoptera,Cynipoidea, Archaeocynipidae) from the Lower Cretaceous of Transbaikalia

A new genus and three new species of parasitic hymenopterans of the family Archaeocynipidae are described from the Lower Cretaceous of Transbaikalia: Khasips alisectus gen. et sp. nov., K. sculptus sp. nov., and K. kovalevi sp. nov. The placement of archaeocynipids in the system of Cynipoidea is discussed.     

<Emphasis Type="Italic">Protocopidosoma</Emphasis> gen. nov. (Hymenoptera,Chalcidoidea, Encyrtidae) from the Late Eocene Danish amber

Protocopidosoma kononovae gen. et sp. nov. from Danish amber is described. The specimen is very similar to representatives of the extant genus Copidosoma Ratzeburg, 1844 and differs from them in the long and wide veins in the forewing, as in most encyrtids from Late Eocene European ambers.     

Palaeobiology of tanaidaceans (Crustacea: Peracarida) from Cretaceous ambers: extending the scarce fossil record of a diverse peracarid group

Diverse assemblages of tanaidacean peracarid crustaceans from western Tethyan continental deposits suggest that the group was relatively common in or around ancient resin‐producing forests. Here we report the results of an examination of 13 tanaidacean specimens from three Cretaceous (Albian to Turonian) French amber deposits. Two new species of the fossil family Alavatanaidae are placed in the previously described Early Cretaceous genus Eurotanais: Eurotanais pyrenaensis sp. nov. from Cenomanian Pyrenean amber (Fourtou, Aude) and Eurotanais seilacheri sp. nov. from Turonian Vendean amber (La Garnache, Vendée). The remaining specimens are placed in three newly erected genera and species (but family incertae sedis): Arcantitanais turpis gen. et sp. nov. from Albian–Cenomanian Charentese amber (Archingeay, Charente‐Maritime), and Tytthotanais tenvis gen. et sp. nov. and Armadillopsis rara gen. et sp. nov. from Pyrenean amber. These are the first formally described fossils that might be related to the paratanaoidean families Nototanaidae and Paratanaidae, sharing with these some putatively derived features and providing possible evidence for the antiquity and morphological stability of these families and the suborder Tanaidomorpha. The distinctive features and character combinations of these fossil taxa are discussed in connection with possible relationships to the living lineages of tanaidaceans. Propagation phase‐contrast X‐ray synchrotron microtomography was used to obtain high‐quality 3D images for some fossils. A discussion is provided on the putative palaeobiology of tanaidaceans and the French resiniferous forest ecosystem. The discovery of these new tanaidaceans extends the palaeogeographical distribution and stratigraphical range of the family Alavatanaidae and sheds new light on the palaeoecology and diversity of tanaidaceans in pre‐angiospermous woodlands.     

New and little known orthopteroid insects (Polyneoptera) from fossil resins: Communication 1

New taxa of uncertain position within the infraclass Polyneoptera (Gryllomantidae fam. nov.: Gryllomantis gen. nov., Lower Cretaceous; Mantoblattidae fam. nov.: Mantoblatta mira gen. et sp. nov., Upper Cretaceous) and within the order Dictyoptera (Pseudojantaropterix gen. nov., Lower Cretaceous) are described. The superfamily Umenocoleoidea of uncertain position within the latter order is discussed on the basis of new information on Jantarimantidae and some other Cretaceous Dictyoptera.

A mid-Cretaceous trichomycete,Priscadvena corymbosa gen. et sp. nov., in Burmese amber

Priscadvena corymbosa gen. et sp. nov., is described from thalli and sporangia emerging from the oral cavity of a click beetle (Coleoptera: Elateridae) in mid-Cretaceous Burmese amber. The fossil contains several features unknown in extant Trichomycetes including a click beetle (Coleoptera: Elateridae) host, spiny, aerial thalli with the entire thallus bearing numerous small uninucleate globular spores and stalks attached to the oral cavity of its host. Based on these features, P. corymbosa gen. et sp. nov. is placed in a new family, Priscadvenaceae fam. nov., and new order, Priscadvenales ord. nov. The new morphological and behavioral features of the fossil add to the diversity of the trichomycetes as currently defined.
