Cerophytidae, commonly known as rare click beetles, represent one of the more basal lineages of the beetle superfamily Elateroidea, with a rather diverse fossil record in the Mesozoic. Four fossil species of this group were previously described from the Cretaceous of Siberia. Here, we redescribe Aphytocerus communis Zherichin, 1977 based on newly found amber specimens from Yantardakh (Taimyr Peninsula). We were able to locate and herein discuss the type specimens of two Mesozoic Siberian cerophytids, Baissophytum convexum Chang, Kirejtshuk & Ren, 2011 and Baissopsis ampla (Chang, Kirejtshuk & Ren, 2011), which were described from the Lower Cretaceous Zaza Formation in Transbaikalia. We compare them with A. communis and discuss the morphology of all three genera, and with Brachycerophytum cretaceum Yu, Ślipiński & Pang, 2019 from Burmese amber.
甲壳纲（Cerophytidae）通常被称为稀有的咔哒甲虫，是甲虫超科（Elateroidea）中较基干的一族，在中生代有相当多样化的化石记录。以前曾在西伯利亚白垩纪描述过该类群的四个化石物种。在此，我们根据新发现的 Yantardakh（泰米尔半岛）琥珀标本，重新描述了 Aphytocerus communis Zherichin, 1977。我们找到了两个中生代西伯利亚陶叶动物的模式标本，即Baissophytum convexum Chang, Kirejtshuk & Ren, 2011和Baissopsis ampla (Chang, Kirejtshuk & Ren, 2011)。我们将它们与 A. communis 进行了比较，并讨论了这三个属的形态，以及与来自缅甸琥珀的 Brachycerophytum cretaceum Yu, Ślipiński & Pang, 2019 的形态。

The Atelestidae are a small family of empidoid flies (Diptera: Empidoidea), including 15 recent species in five genera (Sinclair & Grimaldi, 2020). In contrast, they have a rather high fossil diversity (Table 1), with 28 species in nine genera. These fossil taxa are almost entirely from Cretaceous ambers (Canadian, Lebanese, Myanmar, New Jersey, Spanish), and prior to this study only a single described species from Baltic amber (Nemedina eocenica Sinclair & Arnaud, 2001) was known. The extant species are widespread, with two Afrotropical, three Neotropical, two Nearctic and eight Palaearctic species. This family is recognized within the Empidoidea on the basis of their well-developed anal lobe of the wing, distinct alula, R4+5 unforked, M1+2 usually unforked or forked beyond cell dm, cell cua long, at least as long as cell bm, female tergite 10 absent, male terminalia symmetrical and unrotated, with elongate gonocoxal apodemes and shortened hypandrium (Chvála, 1983; Grimaldi & Cumming, 1999; Sinclair & Cumming, 2006).

A new species Wheelerenomyia negrobovi sp. nov., is described and illustrated from the late Eocene Baltic amber. The genus is placed in the extant subfamily Sciapodinae and includes 13 recognized species, all from Baltic amber. A key to species of this genus is proposed. The following new synonyms are proposed: Wheelerenomyia eocenica Meunier, 1907 = Nematoproctus subparvus Meunier, 1916, syn. nov.; Wheelerenomyia originaria (Meunier, 1907) = Amesorhaga quadrispinosa Negrobov & Selivanova, 2003, syn. nov.; Wheelerenomyia parva (Meunier, 1907) = Nematoproctus parvulus Meunier, 1907, syn. nov.

speciesThe family Coniopterygidae, commonly known as dustywings, occupies a distinctive niche within the Neuroptera, as they are the smallest members of this order (Grimaldi & Engel, 2005; Engel et al., 2018). Characterized by forewing lengths seldom surpassing 5 mm, with a few exceptions (Liu & Lu, 2017), this family has achieved a remarkable speciosity, with approximately 570 extant species scattered across diverse habitats globally (Oswald & Machado, 2018).

The past diversity of Isoptera stands in stark contrast to their extant diversity as the number of fossil termite species is relatively low. Many early-diverging families are unknown from the Cretaceous, a crucial period encompassing the origins of many extant lineages. Therefore, the study of their past diversity dynamics, leading to their present-day diversity, and origin remains shrouded by a dearth of fossil evidence. Here, we report two new taxa of Hodotermopsidae from the Albian Hkamti and mid-Cretaceous Kachin ambers: Hodotermopsella novella gen. et sp. nov. and Tyrannotermes spinifer gen. et sp. nov., the former placed in a new subfamily, Hodotermopsellinae subfam. nov. These new species include the earliest occurrences of Hodotermopsidae in the fossil record. We propose new synonymizations for Cretaceous genera from China Jitermes Ren (= Huaxiatermes Ren and Asiatermes Ren, both syn. nov.) and Meiatermes Lacasa Ruiz & Martínez-Delclòs (= Caatingatermes Martins-Neto, Ribeiro-Júnior & Prezoto, Araripetermes Martins-Neto, Ribeiro-Júnior & Prezoto, Nordestinatermes Martins-Neto, Ribeiro-Júnior & Prezoto, all syn. nov.), and revise the status of the Carinatermitidae stat. nov. We discuss the systematic placement of the Pabuonqedidae as well as the implications of the new hodotermopsids on future divergence-time estimates for Teletisoptera and Isoptera.

This study presents a comprehensive and illustrated catalogue of the forewing venation of the Paleo- and Mesozoic Hemiptera planthoppers. It compiles fragmented information dispersed across various publications, ensuring a uniform interpretation of tegmina venation for fossil taxa. Taxa are presented by family and each species is documented with its stratigraphic age, and tegmina are redrawn from their original illustrations and reinterpreted with relevant comments when necessary. This catalogue aims to be a decisive tool for research into the taxonomy and phylogeny of the group by providing foundational data for comparative analyses of forewing patterns in Fulgoromorpha, as it represents a valuable shared dataset for both fossil and extant taxa. Yanducixius is formally placed in Lalacidae.

The circum-tropically distributed cryptic extant clam shrimp species Cyclestheria hislopi (Baird, 1859) is thought to be the only species of Cyclestherida, although molecular data show that its populations on different continents have large genetic distance (Schwentner et al., 2013). Its parthenogenetical reproduction and direct ovoviviparous development in the dorsal brood chamber indicate that C. hislopi is the sister taxon of all Cladocera (Olsen et al., 1996; Olsen, 1999; Olesen & Richter, 2013; Schwentner et al., 2018). While the large carapace, capable of enclosing the whole body, shows a close similarity with spinicaudatans. In this paper we document its carapace ornamentation by the use of a scanning electron microscope (SEM) and compare to related fossil taxa.
