The fossil in consideration, a small insect larva some 4 mm long, has been described, illustrated and left unnamed by Zippel et al. (2022) as a larva of the beetle family Mordellidae. The same year it was re-identified, unnamed as yet, as a sawfly larva of the family Pamphiliidae (Batelka & Engel, 2022). In our opinion, re-interpretation of the fossil by the latter authors was only partially correct. It demonstrates diagnostic characters of a sawfly larva, but the family attribution of the larva to Pamphiliidae is questionable: in our opinion it is most similar to larval Blasticotomidae (Tenthredinoidea).

Exponential growth of large-scale data for Neuropterida, an iconic group of insects used in behavioural, ecological, and evolutionary studies, has greatly changed our understanding of the origin and evolution of lacewings and their allies. Recent phylogenomic studies of Neuropterida based on mitogenomes, anchored hybrid enrichment (AHE) data, and transcriptomes have yielded a well-resolved and largely congruent phylogeny. Some interfamilial relationships of lacewings, however, remain inconsistent among different phylogenomic studies. Here we re-analysed the genome-scale AHE and transcriptomic data for Neuropterida under the better fitting site-heterogeneous CAT-GTR+G model and recovered a strongly supported and congruent tree for the deeper phylogeny of Neuroptera. Integrating the smaller but more broadly sampled AHE and the larger but less-sampled transcriptomic data, we present a holistic phylogeny of Neuropterida from which to explore patterns of evolution across the clade. Our re-analyses of the largest available datasets of Neuropterida highlight the significance of modelling across-site compositional heterogeneity and model comparison in large-scale phylogenomic studies of insects.

The representatives of the superfamily Evanioidea are easily distinguishable from all other extant and extinct Hymenoptera because of their metasoma (sometimes rounded) articulated high on the propodeum and well above the metacoxae (e.g., Goulet & Huber, 1993). Recent phylogenetic studies on the superfamily Evanioidea have shown strong support for its monophyly and for the monophyly of the Evaniidae even when fossil taxa are included (e.g., Li et al., 2018; Parslow et al., 2020; Jouault et al., 2022). According to the most recent analysis, the superfamily arose during either the Upper Triassic or the Lower Jurassic. Still, its earliest species are recorded in the younger Middle Jurassic, and its crown-group representatives during the Lower Cretaceous (Jouault et al., 2022: fig. 8). The stem Evaniidae are estimated to arise during the Upper Jurassic while their crown group has a more recent origin, likely around the Cretaceous-Paleogene boundary. Extant evaniid wasps are common, nearly cosmopolitan, and moderately diversified (about 580 extant species in 21 genera) even if this diversity is underestimated (Deans, 2005; Mullins et al., 2012). Little is known about the biology of extant evaniids, but their larvae are considered predators of cockroach eggs in oothecae (Huben, 1995). The Evaniidae have a good fossil record with the oldest species known from the late Hauterivian, numerous species documented up to the Miocene, and an important diversity in Burmese amber (e.g., Rasnitsyn et al., 1998; Nel et al., 2002; Deans et al., 2004; Jennings et al., 2012; Shih et al., 2020). Nevertheless, their past diversity is still underestimated.
Evanioidea超科的代表很容易与所有其他现存和已灭绝的膜翅目区分开来，因为它们的交代体（有时是圆形的）高高地铰接在蜂胶上，远高于元壳纲（例如，Goulet和Huber，1993）。最近对Evanioidea超科的系统发育研究表明，即使包括化石分类群，也强烈支持其单系性和Evaniidae的单系性（例如，Li等人，2018；Parslow等人，2020；Jouault等人，2022）。根据最新的分析，该超家族出现在上三叠纪或下侏罗纪。尽管如此，其最早的物种记录在更年轻的中侏罗纪，其冠群代表在下白垩纪（Jouault et al.，2022：图8）。据估计，茎Evaniidae起源于上侏罗纪，而它们的冠群起源更近，可能在白垩纪-古近纪边界附近。现存的伊凡尼黄蜂很常见，几乎是世界性的，并且适度多样化（21属约580种现存物种），即使这种多样性被低估了（Deans，2005；Mullins等人，2012年）。对现存的伊凡虫的生物学知之甚少，但它们的幼虫被认为是卵鞘科蟑螂卵的捕食者（Huben，1995）。Evaniidae有着良好的化石记录，其已知的最古老的物种可以追溯到豪特里阶晚期，记录到中新世的许多物种，以及缅甸琥珀中的重要多样性（例如，Rasnitsyn等人，1998年；Nel等人，2002年；Deans等人，2004年；Jennings等人，2012年；Shih等人，2020年）。尽管如此，他们过去的多样性仍然被低估。

The elateriform genus Parelateriformius Yan & Wang from the Middle–Late Jurassic Daohugou beds has been placed previously in the extinct Lasiosynidae or the extant Eulichadidae. Our reinvestigation of the type specimens and additional materials suggests that the character combination of Parelateriformius (e.g., tarsomeres 2–4 distinctly lobed, posterior pronotal margin crenulate, radial cell short and with truncate base, and metakatepisternal suture complete) is not accordant with either Lasiosynidae or Eulichadidae. Instead, it should belong to the family Dascillidae and appears closely related to the extant Petalon. A new species of Parelateriformius is also described, as P. grimaldii Li & Cai sp. nov. Our discovery highlights the antiquity of Dascillidae, which is consistent with the recent fossil-calibrated molecular dating of beetles.

A new species of the ‘flat-backed’ millipede family Trichopolydesmidae, Monstrodesmus grimaldii sp. nov., is described from the mid-Cretaceous Burmese amber. Detailed morphological characters are provided on the basis of three well-preserved adults (two males and one female), one male juvenile, and seven additional specimens, using confocal laser scanning microscopy (CLSM) and microcomputer tomography (μCT) with computer-aided 3D-reconstructions. The new species can be placed most likely in the extant genus Monstrodesmus by presenting great similarities to living species.

Among the calopteran damselflies, the family Epallagidae was clearly dominating the diversity of the Holarctic Cenozoic (11 described species in eight extinct genera), while the Calopterygidae were extremely rare at the same time (six Cenozoic species in two extant and one fossil genera) (Fossilworks database at http://www.fossilworks.org/cgi-bin/bridge.pl?action=home, consulted 21/10/2022). They mainly belonged to the extinct subfamily Eodichrominae Cockerell, 1923, and their most diverse genus was the early Eocene genus Labandeiraia Petrulevičius et al., 2007, known from compression fossils from the lacustrine Green River Formation (USA) and the marine Fur Formation in Denmark (Petrulevičius et al., 2007; Bechly et al., 2020).
在热翅目豆娘中，Epallagidae家族显然在全北极新生代的多样性中占主导地位（8个已灭绝属中的11个已描述物种），而同时热翅目动物科极为罕见（两个现存属和一个化石属中的6个新生代物种）（Fossilworks数据库http://www.fossilworks.org/cgi-bin/bridge.pl?action=home，咨询日期：2022年10月21日）。它们主要属于已灭绝的Eodichrominae Cockerell亚科，1923年，它们最具多样性的属是始新世早期的Labandeiraia Petrulevičius等人，2007年，从湖泊绿河组（美国）和丹麦海苔组的压缩化石中已知（Petrulewičius et al.，2007；Bechly等人，2020）。

The previous issue of Palaeoentomology brought the first set of papers honoring David A. Grimaldi on the occasion of his 65th birthday. With the current one, it is continued, in recognition of his impact on the fields of amber studies, palaeontology, palaeo- and neoentomology, and evolutionary biology. After the success of Jurassic Park (both the Michael Crichton book from 1990 and the Steven Spielberg movie from 1993) everyone wants to know more know about the miracles of long ago that are encapsulated in petrified resin. Amber: window to the past (Grimaldi, 1996) originally published to accompany a 1996 exhibition at the American Museum of Natural History in New York, explored the properties of amber and revealed its role in tracing evolutionary history and its use in the decorative arts and jewelry. This surge in interest in amber and palaeoentomology resulted the establishment of the International Palaeoentomological Society in 2001 at the Second International Congress on Palaeoentomology—Fossil Insects, and particularly the study of insect inclusions in amber from various parts of the world. An essential reference for anyone interested in the study of amber fossils, insect evolution, and the earliest stages of the association between insects and angiosperms devoted to amber from New Jersey and edited by Grimaldi (2000), provided an incredibly vivid window into animal and plant evolution in the Late Cretaceous. Another book—Evolution of the insects (Grimaldi & Engel, 2005)—is the first comprehensive synthesis of all aspects of insect evolution integrating the living and fossil record. The book was a great source of information about what we know at the time of its publication, but also highlighted what we do not know, making the book a great source of inspiration for subsequent studies.

The damselfly family Coenagrionidae is rather frequently found in the Cenozoic fossil record (Nel & Paicheler, 1993), but it remains unknown in the Mesozoic. The known fossils are generally isolated wings, very difficult to accurately attribute to precise genera, to the point that many fossils can be only considered as ‘genera and species undetermined’ (Nel et al., 1997). The oldest described coenagrionid fossil is the late Palaeocene Marado marado Petrulevičius, 2021 (Maíz Gordo Formation, Argentina), a genus and species based on an isolated incomplete wing. Thus, other Eocene representatives of the family are important for future accurate dating of the occurrence of the family and its subdivisions, especially those that have been attributed to extant genera; a future step after the important work of Dijkstra et al. (2014) for the understanding of the evolution of these damselflies.
