Three new species, <em>Tibicina lata</em> <strong>sp. nov.</strong>, <em>Tibicina boulardi</em> <strong>sp. nov. </strong>(Tibicinae), and <em>Cicada tithonus</em> <strong>sp. nov. </strong>(Cicadinae) are described based on forewing characters. Other singing cicadas from Willershausen are assigned to <em>Tibicina</em> sp., <em>Tibicina</em> aff. <em>haematodes</em>, <em>Cicada</em> aff. <em>orni, Cicada </em>aff. <em>lodosi</em> and indeterminable species.</p> MAX MOULDS, UWE KAULFUSS, ALEXANDER GEHLER Copyright (c) 2023 Magnolia press limited Mon, 30 Oct 2023 00:00:00 +1300 <p><strong>Evolution of Insect Diversity in the Permian and Triassic</strong></p> <p>The global warming that occurred during the Permo-Triassic transition, following the end of the Late Paleozoic glaciation, and the resulting responses of the biota to the changing environment, are considered important analogs for understanding rapid future warming scenarios. While there has been extensive research on the patterns and extent of diversity in plants, tetrapods, and marine invertebrates during the Permo-Triassic, the study of insect diversity and the evolution of their faunal composition has been relatively limited. The question of whether there were insect extinctions during this period continues to be a subject of debate. Here, we present a statistical study on taxonomic diversity of insects—at specific, generic and familial levels—throughout the Permian and Triassic, with subsampled context on the reported global occurrences. Our result show that more than one insect extinction events, accompanied by significant diversity drop and turnovers of faunal compositional, occurred in the Permian and Triassic. All the uncovered insect diversity crises exhibit strong correspondence with the well-known marine mass extinction events in the Middle Permian, Permo-Triassic transition, Carnian, and Rhaetian, whilst the marine correspondence with the Early Permian insect crisis is less pronounced. Insects, being a major component of terrestrial ecosystems, demonstrate varied diversity responses to climatic changes in Permian and Triassic. Our study sheds new light on the intricate interplay between insect diversity evolution and the changing environmental conditions during these critical geohistorical periods.</p> SHUANG-MAO GUI, YU-CHU LIU, LI TIAN Copyright (c) 2023 Magnolia press limited Mon, 30 Oct 2023 00:00:00 +1300 <p><strong>First fossil record of <em>Trichosteleum</em> (Bryophyta: Sematophyllaceae) from mid-Miocene Zhangpu amber in Asia</strong></p> <p>The evolutionary history of terrestrial moss in Asia during the Cenozoic is poorly interpreted in largely because of very limited fossil evidence. The middle Miocene Zhangpu amber is the sole resin source of moss fossils in China, which shows a diverse moss population during the mid-Miocene Climatic Optimum. In this study, we reported the discovery of a gametophyte fragment of moss fossil in a well-preserved amber inclusion from the middle Miocene of Zhangpu, Southeast China. The observation methods involved light microscopy and synchrotron radiation–based X-ray microcomputed tomography analysis on the amber inclusions. The fossil has lanceolate leaves with involute margins, long linear laminal cells with unipapillae, well-developed and enlarged alar cells, and an absence of costae. The fossil is assigned to the extant <em>Trichosteleum</em> and represents the only known occurrence of a fossilized <em>Trichosteleum</em> member in Asia. This finding enhances our comprehension on the moss diversity within Zhangpu amber and establishes a first record of <em>Trichosteleum</em> in Asia.</p> ZI-XI WANG, XIE-TING WU, SU-XIN YIN, CHONG DONG, WEI-QIU LIU Copyright (c) 2023 Magnolia press limited Mon, 30 Oct 2023 00:00:00 +1300 <p><strong>Cretaceous beetles of the Jinju Formation (Coleoptera): Archostemata</strong></p> <p>The beetles from the Lower Cretaceous Lagerstätte in South Korea, Jinju Formation, remain largely unstudied.

Despite their well-documented fossil record during the Mesozoic, many aspects of their diversity and evolution remain poorly understood. In this study, we increase the fossil record of Mecoptera by describing a new taxon from the Paleocene Paskapoo Formation (Alberta, Canada). This specimen is described as <em>Bittacus</em>?<em> paskapooensis</em> <strong>sp. nov. </strong>(Raptipedia: Bittacidae) but is assigned with caution to <em>Bittacus</em> due to the lack of apomorphic wing venation characters for this genus.</p> CORENTIN JOUAULT, BAPTISTE COUTRET, KURT O.

We here document the discovery of a new genus and species, <em>Thagyaminobythus martini</em> <strong>gen. et sp. nov.</strong>, from Kachin amber, emphasizing the extraordinary diversity of chrysidoid wasps in this deposit. The genus is left as <em>incertae sedis</em> within the superfamily because it exhibits a combination of Scolebythidae, Bethylidae and Chrysididae features. We discuss the possibility that <em>Thagyaminobythus martini</em> <strong>gen. et sp. nov.</strong> could retract its posterior metasomal segments and the co-occurrence of such a structure in several chrysidoid families.</p> SIMON ROSSE-GUILLEVIC, CORENTIN JOUAULT, MANUEL BRAZIDEC Copyright (c) 2023 Magnolia press limited Mon, 30 Oct 2023 00:00:00 +1300 <p><strong>A striking new XXL-size flat bug from mid-Cretaceous Burmese amber: <em>Archemezira nuoyichenae</em> sp. nov.

The origin, distribution, and geology of the Yanliao biota are poorly understood to date. Here we describe and illustrate two new species of protopsyllidiids, namely <em>Sinopsocus yananensis </em><strong>sp. nov.</strong> and <em>Subaphidulum sinica </em><strong>sp. nov.</strong> from the Middle Jurassic Yan’an Formation near Yan’an City, Shaanxi Province, North China. <em>S. yananensis</em> <strong>sp. nov.</strong> closely resembles the type species<em> Sinopsocus oligovenus</em> from the Haifanggou Formation at Beipiao City, West Liaoning, Northeast China. The new discoveries not only increase the diversity of Mesozoic protopsyllidiids but also provide thread for understanding the origin of the Yanliao biota.</p> MIN-MIN XU, MARINA HAKIM, DI-YING HUANG Copyright (c) 2023 Magnolia press limited Mon, 30 Oct 2023 00:00:00 +1300 <p><strong>Oribatid mites in Burmese amber I. First record of the family Achipteriidae (Acariformes, Oribatida) in Cretaceous amber, with the description of a new species of <em>Cerachipteria</em> Grandjean, 1935</strong></p> <p>Burmese amber originates from the Hukawng Valley in northern Myanmar (Burma). Shi <em>et al</em>. (2012) proposed an age of <em>ca</em>. 99 Ma based on zircon dating, whereas Smith &amp; Ross (2018) proposed an age of 100 Ma based on sediments inside amber produced by bored bivalves. Regarding the plant producing resin Cruickshank &amp; Ko (2003) recorded spores both of Araucariaceae and Taxodiaceae origin. Poinar <em>et al</em>. (2007) proposed an araucariacean origin due to the similitudes with modern kauri pines (<em>Agathis</em>) from New Zealand, while Grimaldi &amp; Ross (2017) suggested the possibility of a Cupressaceae (<em>Metasequoia</em>) origin. Although amber inclusions from Myanmar were first described by Cockerell (1916), great interest (and a huge number of papers) in this biota started only two decades ago.</p> ANTONIO ARILLO, LUIS S.

The geological background of the Konservat-Lagerstätte was described by Pedersen &amp; Surlyk (1983). The formation preserves a rich record of earliest Ypresian (Eocene, <em>ca</em>. 55 Ma) fossil insects (<em>e</em>.<em>g</em>., Madsen &amp; Rasmussen, 2021). The fauna includes many hemipterans mostly representing Heteroptera and Sternorrhyncha but the diverse modern family Cicadellidae (leafhoppers) is represented by a single specimen among the &gt;20,000 available insect fossils discovered so far.</p> CHRISTOPHER H.

Archaeological evidence confirms that amber played a significant role in long-distance material exchange and trade during ancient times. Baltic amber, in particular, was extensively traded in the Near East region during the Bronze age (<em>e</em>.<em>g</em>., Todd, 1985). The emergence of the Silk Road trade additionally facilitated the spread of amber and its products in the Far East. Extensive archaeological excavations conducted across the Eurasian steppe (Treister, 2020), as well as in China and the Korean Peninsula, have yielded numerous amber artifacts originating from the Baltic Sea (<em>e</em>.<em>g</em>., Park <em>et al</em>., 2016; Xiao <em>et al</em>., 2020; Liu <em>et al</em>., 2022). The northern region of Myanmar served as a significant source of amber material in Asia during ancient times, and amber from this area and its products have also been discovered in the Han Dynasty (206 BCE–220 AD) tombs in China (Chen <em>et al</em>., 2019; Zhao <em>et al</em>., 2023; Liu <em>et al</em>., 2023). It is generally accepted that the ancient amber artifacts in China were primarily made from amber obtained from both the Baltic region and Myanmar (<em>e</em>.<em>g</em>., Xu, 2008). However, the scarcity of amber in Iron Age sites across South and Southeast Asia impedes tour comprehensive understanding about its usage and trade among this specific area.</p> QI LIU, SONG LIU, LIANG-BO LÜ, XING-PING LI, QING-HUI LI, CHUNG-JUNG LIAO Copyright (c) 2023 Magnolia press limited Mon, 30 Oct 2023 00:00:00 +1300 <p><strong>An unusual artematopodid beetle from Early Cretaceous Wealden amber (Coleoptera: Elateroidea: Artematopodidae)</strong></p> <p>Early Cretaceous Wealden amber of the Isle of Wight (early Barremian, ~125 Ma) represents one of the oldest known fossiliferous ambers. Here we describe the first fossil beetle from the deposit, and first British coleopteran amber inclusion, the artematopodid <em>Valdopogon simpsoni</em> <strong>gen. et sp. nov</strong>. Despite its fragmentary nature, the fossil possesses a puzzling combination of characters unseen in modern Artematopodidae, namely equally long abdominal ventrites I and II, concave sutures between ventrites I–V, and absence of elytral striation. <em>Valdopogon </em>contributes to our understanding of the morphological evolution of this once diverse group of elateroid beetles.</p> ERIK TIHELKA, EDMUND A.
