A new species of silvanid flat bark beetle, Nausibius radchenkoi sp. nov., is described and illustrated based on a well-preserved inclusion in Eocene Rovno amber. It is the first fossil species of Nausibius, a cosmopolitan genus with representatives living worldwide today. The current finding confirms both the Eocene age of the genus and the presence of representatives of the genus in forest palaeoecosystems of Europe in that time. In addition, Austronausibius aenigmatista Alekseev & Bukejs, 2022, previously described from Rovno amber, is documented in Baltic amber for the first time. Thirteen common species of Coleoptera (including one newly recorded here) known from these two East European ambers are listed. The newly described species, as well as some other beetle taxa in Eocene European habitats (where Rovno and Baltic ambers were produced), have several congeners that live today in artificial synanthropic habitats, namely warehouses storing various food products.

A new species of palaeodictyopteridan insect, Heolus martinclosasi sp. nov., based on a partial wing, has been identified in the uppermost Pennsylvanian (Stephanian C local stage) deposits of the Castellar de N’Hug-Camprodon Basin, located in the Surroca-Ogassa coalfield within the Pyrenees of Catalonia, Spain. This species belongs to the Palaeodictyoptera, and is the first of this order described from the Paleozoic deposits of Spain. Heolus martinclosasi sp. nov. is the second species within the relatively small Heolidae family, originally described by Handlirsch in 1906, in the USA. This new species was found alongside remains of in situ fossil plants such as Calamites suckowii, Sphenophyllum oblongifolium, and marattialean tree ferns, all of which grew between river channels. This suggests that these insects possibly lived in lake-like, permanently inundated floodplain deposits.

Mantispoidea (Insecta, Neuroptera) are well-known for the hypermetamorphic larval development and for most adults having praying mantis-like raptorial forelegs. Currently, this superfamily comprises Berothidae (beaded lacewings) and three raptorial mantispoid families: Rhachiberothidae (thorny lacewings), Dipteromantispidae and Mantispidae (mantidflies or mantid lacewings). It includes about 530 extant species in 74 genera, and 143 extinct species in 97 genera from the Upper Triassic to the Miocene. Berothidae, well-known for some adults with scale-like setae on the female wings, currently includes 119 extant species in 26 genera, and 59 extinct species in 37 genera from the Upper Triassic to the Eocene. Rhachiberothidae represents the relictual group of Mantispoidea, comprising only 14 extant species across four genera, which are confined to the Afrotropical Region. However, the abundant fossil records (28 species and 21 genera), especially from the Cretaceous, highlight the past glory of this family. The Cretaceous dipteran-like family Dipteromantispidae, comprising ten species across nine genera, remains enigmatic in terms of its phylogenetic status. Mantispidae, the largest family within Mantispoidea, comprises approximately 395 extant species across 44 genera and 46 extinct species in 30 genera, ranging from the Lower Jurassic to the Miocene. This family is distinctive from other raptorial families for its highly mobile and variously elongated prothorax. Here, we describe several new genera and species from mid-Cretaceous Kachin amber, Myanmar: Three new species of Osmyloberotha Khramov, 2021 (O. dispersa sp. nov., O. chenzuyini Zhuo, Li & Liu sp. nov. and O. magnimaculata sp. nov.) in Berothidae, with a detailed redescription of O. simpla Khramov, 2021; two new genera and three new species (Paraberothinae: Paraberothoides longispina Li, Zhang & Liu gen. et sp. nov.; Subfamily unknown: Dicranoberotha zhangzhiqiae Zhuo, Li & Liu gen. et sp. nov., Dicranoberotha liumohanae Zhuo, Li & Liu gen. et sp. nov.) of Rhachiberothidae, three new species (Enigmadipteromantispa dilatata Li, Nakamine, Yamamoto & Liu sp. nov., Kurtodipteromantispa relicta Li, Nakamine, Yamamoto & Liu sp. nov. and Kurtodipteromantispa univenula sp. nov.) of Dipteromantispidae, as well as four new genera and five new species (Symphrasinae: Parvosymphrasites aploneura Li, Lin, Liu & Wang gen. et sp. nov. and Proplega evelynae Zhuo, Li & Liu gen. et sp. nov.; Subfamily unknown: Haplacantha robusta gen. et sp. nov., Haplacantha tenuis gen. et sp. nov. and Mesomantispoides felixoporcus gen. et sp. nov.) of Mantispidae. Sinuijumantispa So & Won, 2022, previously classified within Drepanicinae, is now recognized as a stem group of Mantispidae, which is possibly related to Mesomantispoides gen. nov. or Mesomantispinae. Our new findings offer crucial insights into the taxonomy, morphological diversity and evolution of Mantispoidea.
螳螂poidea(昆虫纲,神经昆虫目)以幼虫的超变态发育和大多数成虫具有螳螂般的猛禽前肢而闻名。目前,该超科包括珠蛉科(Berothidae)和三个猛禽螳螂科:Rhachiberothidae(多刺草蛉科)、Dipteromantispidae 和 Mantispidae(螳螂蜓科或螳螂草蛉科)。它包括从上三叠世到中新世的 74 属中的约 530 个现存物种和 97 属中的 143 个灭绝物种。蝶科(Berothidae)因一些成虫雌翅上有鳞片状刚毛而闻名,目前包括从上三叠世到始新世的 26 属中的 119 个现生种和 37 属中的 59 个灭绝种。Rhachiberothidae是螳螂科的孑遗类群,仅有4属14个现生种,分布于非洲热带地区。然而,丰富的化石记录(28 种 21 属),尤其是白垩纪的化石记录,彰显了该科过去的辉煌。白垩纪的双翅目类双翅目(Dipteromantispidae)科由 9 属 10 种组成,其系统发育状况仍是一个谜。螳螂科(Mantispidae)是螳螂目(Mantispoidea)中最大的科,包括 44 属中的约 395 个现存物种和 30 属中的 46 个灭绝物种,分布于下侏罗世到中新世。该科与其他猛禽科不同,其前胸具有高度的活动性和不同程度的伸长。在这里,我们描述了缅甸克钦琥珀中白垩纪中期的几个新属和新种:O. dispersa sp. nov., O. chenzuyini Zhuo, Li & Liu sp. nov. 和 O. magnimaculata sp. nov. ),并对 O. simpla Khramov, 2021 进行了详细的重新描述;两个新属和三个新种(Paraberothinae:Paraberothoides longispina Li, Zhang & Liu gen:Dicranoberotha zhangzhiqiae Zhuo, Li & Liu gen. et sp. nov、Kurtodipteromantispa relicta Li, Nakamine, Yamamoto & Liu sp:和 Proplega evelynae Zhuo, Li & Liu gen.Sinuijumantispa So & Won, 2022,以前被归入 Drepanicinae,现在被认为是螳螂科的一个干群,可能与 Mesomantispoides gen.我们的新发现为研究螳螂科的分类、形态多样性和进化提供了重要的启示。

A new species of Rhagionidae, Symphoromyia odileae, is described from the Middle Eocene Baltic amber. Chrysopilus meunieri Kerr, 2010, also from the Baltic amber, is redescribed on the basis of a new specimen, and its attribution to the genus Chrysopilus is confirmed. This specimen of Chrysopilus can be considered as the first accurate fossil representative of this genus. Although Symphoromyia odileae sp. nov. shows the diagnostic characters of the genus, it has also a series of hind tibia macrosetae, unlike in the other representatives of the genus. Chrysopilus meunieri Kerr, 2010 differs from the extant species in the cell cua being open.

Encyrtidae are one of the largest and most diverse families of chalcidoid wasps found both today (Noyes, 2023) and in Eocene ambers (Simutnik, 2021; Simutnik & Perkovsky, 2023). The earliest known Encyrtidae have been found in middle Eocene Sakhalinian amber (Simutnik, 2021; Simutnik et al., 2021b). They differ significantly from both extant encyrtids as well as those occurring in late Eocene European ambers, many of which feature peculiar characters (Simutnik et al., 2020, 2023; Simutnik, 2021). To date, some 20 species in 18 extinct genera of Encyrtidae have been described from late Eocene Baltic, Danish and Rovno ambers (Simutnik et al., 2021a, 2022c, 2023; Simutnik & Perkovsky, 2023).

The superorder Archaeorthoptera (or total group of the extant Orthoptera) was exceedingly diverse during the Late Carboniferous and Permian. Most of the species described to date are comparatively remote relatives of Orthoptera (Archaeorthoptera nec. Panorthoptera). The Panorthoptera are a clade including species more closely related to crown Orthoptera, sharing with them synapomorphies in their wing venation, viz. division of the anterior-most branch CuPa of CuP into two branches; fusion of the anterior branch CuPaα of CuPa with CuA (or M+CuA). The Orthoptera sensu stricto are then characterized by the posterior branch of CuPa (CuPaβ) generally simple, and by the broadened (‘saltatorial’) metafemora (Béthoux & Nel, 2002). The Panorthoptera are quite rare in the early Late Carboniferous (Béthoux et al., 2012; Gu et al., 2014, 2017). Thus, any new fossil attributable to this clade is welcome to clarify the history of its diversification.

The family Chrysopidae (green lacewings) is a highly diverse group of Neuroptera, with rich fossil records. The Cenozoic fossils of green lacewings currently comprise 21 genera and 42 species. Here we describe two new green lacewing species of the tribe Chrysopini, tentatively placed in the genus Chrysopa Leach, 1815, namely Chrysopa? extensa sp. nov. and Chrysopa? prominenta sp. nov. from Eocene Baltic amber and Miocene Mexican amber, respectively. These species represent the second chrysopid occurrence and the first record of the tribe Chrysopini from Baltic amber, and the first occurrence of Chrysopidae from Mexican amber, respectively. Both new species are assigned to Chrysopini based on the following characters: the intramedian cell eutriangular without crossvein, and the basal-most RP branch origins distal to the intramedian cell in the forewing.

Psychopsidae, a small family of Neuroptera, comprises only 27 extant species and 38 fossil species. The limited species records and poor specimen preservation greatly hinder our exploration of the early evolutionary process of Psychopsidae. In this paper, one new genus with one new species, Nullipsychops longialatus gen. et sp. nov., and two new species of Cretapsychops Jepson et al., 2009, namely, C. stigmosus sp. nov. and C. epunctatus sp. nov., are described from the Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia of China. Based on the new fossil material, we summarized in detail the intraspecific variation of venation and wing markings in Cretapsychops decipiens Peng et al., 2010. Furthermore, we also systematically review the morphological features of Cretapsychops among Cretaceous lineages and Jurassic lineages; and a key to Cretapsychops species is provided. Considering the relatively rare Jurassic psychopsids, the newly discovered Jurassic psychopsids enhance the species diversity of Jurassic psychopsids, and promote our understanding of the early evolution of Psychopsidae.

A new enigmatic genus and species presumably belonging to the cyclostome braconid parasitoid subfamily Rhyssalinae, Electroncophanes laticauda Belokobylskij & Zaldívar-Riverón gen. et sp. nov., are described and illustrated from the late Eocene Baltic amber. This new genus is characterised by having a wide and laterally compressed ovipositor, a unique character in the cyclostome braconids, and distally thickened ovipositor sheaths. It also has the fore wing with a postfurcal position of the recurrent vein (m-cu), distally closed brachial (second subdiscal) cell, not interstitial parallel vein (Cu1a), and a long submedial (subbasal) cell of the hind wing. Electroncophanes gen. nov. is placed in the new rhyssaline tribe Electroncophanini tribus nov. The presence of the flat and wide ovipositor found in the new species is discussed.
本研究描述并展示了来自晚始新世波罗的海琥珀中的一个神秘的新属和新种--Electroncophanes laticauda Belokobylskij & Zaldívar-Riverón gen. et sp.该新属的特点是产卵器宽大且侧面压缩,这在环口腕足动物中是独一无二的,而且产卵器鞘上部加厚。它的前翅还具有后糠状位置的复脉(m-cu)、上部闭合的肱状(第二亚盘状)细胞、无间隙的平行脉(Cu1a)以及后翅的长亚中轴(亚基底)细胞。Electroncophanes gen.讨论了在新种中发现的扁平而宽的产卵器的存在。

We examined three astigmatic mite specimens phoretic on the beetle Glesoconomorphus ekaterinae from Eocene Rovno amber. Due to the precious nature of this amber piece, housing the name-bearing holotype of the host beetle, traditional trimming for the application of high-resolution imaging techniques at small focal distances was unfeasible. To overcome this challenge, we employed a combination of confocal microscopy relying on the autofluorescence properties of the mite chitinous exoskeleton and long working distance / water immersion objectives. This innovative approach successfully resolved the minute mite features from a considerable distance (700 μm). Based on these data, we describe many taxonomically important characters and identify these mites as a new species, Congovidia glesoconomorphi sp. nov., within the family Hemisarcoptidae. This represents the first fossil record for the mite family. Additionally, we provide a key for phoretic deutonymphs of all known species of Congovidia. As larvae of many extant Eurypinae live in subcortical spaces of decomposing tree trunks, we suggest that the mite C. glesoconomorphi similarly occupied subcortical niches in decayed wood and utilized adult beetles of G. ekaterinae for dispersal.
