We describe two new species—Holopogon hyalopterussp.nov. And Molobratia zhangisp.nov.—and report the first record of Cyrtopogon centralis for Liaoning Province. Morphological identifications were supported by molecular evidence from 34 full-length (658 bp) COI barcode sequences. Both Automatic Barcode Gap Discovery (ABGD) and multi-rate Poisson Tree Processes (mPTP) analyses consistently delineated three distinct species, confirming the morphological conclusions. This research provides the first systematic study of Liaoning's asilid diversity, highlighting the province's underexplored status and its importance for understanding insect biogeography in Northeast Asia.

In this study, we obtained the complete mitogenome of Lutjanus fulvus from a specimen collected in Pakistani waters (63.95°E, 25.30°N) by utilizing high-throughput sequencing technology, then we characterized it and downloaded the complete mitogenomes of closely related species to constructed phylogenetic trees based on 13 protein-coding genes (PCGs) using Bayesian Inference (BI) methods. The complete mitogenome of L. fulvus is a typical closed circular double-stranded DNA molecule, was 16 493 bp in length, with a relatively low G content (16.2 %) and a high AT pronounced bias (52.8 %). The genome comprises 37 genes: 22 tRNAs, two rRNAs, 13 PCGs, and one putative control region (D-loop). Among the 13 PCGs, four types of stop codons (TAA, TAG, AGA, T--) are observed, and all genes, except for COX1, which starts with GTG, begin with the ATG start codon. The BI trees exhibited consistent topologies, indicating close relationships with Lutjanus vitta and Lutjanus ophuysenii. This study provides valuable genomic insights into the mitogenome of L. fulvus, enhancing our understanding of phylogenetic relationships within the Lutjanidae family and offering a fundamental reference for further exploration of mitogenomes in the Lutjanus genus. Furthermore, these data contribute new molecular evidence and theoretical foundations for the classification, genetic diversity studies, and the conservation and management of L. fulvus.

Eggshells display stable patterns and are able to provide solid basis for insect identification. Notodontidae are usually considered as significant pests for their larvae causing serious damage during outbreaks, underscoring the importance of early and accurate identification. In this study, nine notodontid eggshells from eight genera were compared using cold field emission scanning electron microscopy, in order to discover detailed evidence for the egg identifications. The eggshells exhibit morphological differences on the micropyle area, chorion sculpture, aeropyle density, and polygonal wall details. Notably, the eggshell ornamentations are different between the congeneric species E. splendida and E. cristata, highlighting the potential of eggshell morphology to enhance taxonomic research.

The family Lepetidae Gray, 1850 is a small group of limpets widely distributed from tidal zone to abyssal. The monophyly of the family is supported by both morphological traits and molecular phylogenetic analyses, but phylogenetic relationships within the family remain unsolved. The current phylogenetic analyses based on four gene markers (COI, 16S, 12S and H3) revealed a highly supported clade including the Northwestern Pacific lepetids. Sagamilepeta sagamiensis is a sister species to Lepeta caeca and should be synonymized with the genus Lepeta on the basis of morphological traits and genetic distances. Cryptobranchia is a separate genus which differs from Lepeta in both radular morphology and phylogenetic position. In addition, the analyses revealed the second undescribed species of the genus Limalepeta which has amphiboreal distribution. Keys to the identification of the Northwestern Pacific Lepetidae are given based on the shell and radula morphology.

Changes in species diversity may be accompanied by morphospace variation at different spatial and temporal scales. Evidence indicates that shifts in species diversity and morphological disparity (morphodisparity) are prevalent among marine invertebrates across the geological scale. This study estimates the diversity and morphodisparity of ammonites across the Jurassic–Cretaceous (J/K) transition—from the Tithonian to the Valanginian stages—by examining 158 specimens representing 33 species and 21 genera from four localities in central Chile. Ammonites were photographed in lateral and frontal views to perform geometric morphometrics analyses based on landmarks and semilandmarks. The resulting shapes were evaluated using multivariate statistical approaches across geological stages. Results suggest that faunal changes in diversity during the J/K transition are associated with significant variations in ammonite morphospace. Notably, significant changes in morphodisparity were observed between the late Tithonian and early Berriasian, and again between the early and late Berriasian. This study not only documents faunal turnover in central Chile but also contributes to our understanding of how extinction pulses can drive morphological innovation or constraint during key evolutionary transitions.

Pararhagadochir is a genus of Embioptera comprising 19 valid species distributed in the Neotropical region. Ten species occur in Brazil. The information described in this work was made possible through expeditions dedicated to collecting Pararhagadochir colonies containing females and immatures, which were fundamental for this study. Additionally, sporadic collections were carried out in various municipalities, complementing the understanding of the studied species. In this study, the male of the species Pararhagadochir castaneus Salvatierra, 2020 (only known for the holotype) is redescribed, and for the first time data on female and nymphal stages, biological data, and intraspecific variations are presented. A new species Pararhagadochir Davis, 1940 from several localities of Tocantins is described and illustrated here. Finally, we provide an updated key and a distribution map with new records for the Brazilian species.

In this study, we first obtained the complete mitochondrial genome of Contarinia maculipennis, an important worldwide invasive flower and vegetable pest, from Hengzhou, Nanning, Guangxi, China, then annotated its mitogenome, and analyzed its tRNA secondary structures, which is the first report of comprehensive set of the tRNA secondary structures provided in Family Cecidomyiidae. And we also annotated Dasineura ulmaria's mitogenome sequence from NCBI too. By comparing the rearrangement features of the mitogenome of C. maculipennis with all the other identified and sequenced gall midge species as well as the outgroups, we identified the particularities of rearrangement features and tRNA-Val secondary structure of C. maculipennis. By further sorting out and analyzing the tRNA-Val secondary structures of all the identified gall midge species as well as the outgroups, combined with the classification, phylogenetic analysis and rearrangement characteristics, we found some patterns in Cecidomyiidi as well as Cecidomyiinae, and especially the related powerfully verified particularities of C. maculipennis, which may be a potential key to reveal its extensive host radiation.

The spread of non-indigenous species (NIS) is a major threat to native biodiversity worldwide. The Mediterranean Sea is particularly affected by such a phenomenon, with high introduction rates and harmful consequences on its biota and ecosystems. Based on an integrative taxonomic approach, we hereby report the widespread occurrence of two NIS bivalves (Cerastoderma edule and Mytilopsis leucophaeata) in the Sacca di Goro Lagoon (Italy, north Adriatic Sea). The record of the former species is the first for Italy and the Mediterranean Sea sensu stricto, and also accounts for the first confirmed evidence of this species invading new areas worldwide, whilst that of the latter potentially clarifies the taxonomic uncertainties regarding the species that has invaded the north Adriatic until 2008.

非本地物种（NIS）的传播是全球本地生物多样性的主要威胁。这种现象对地中海的影响尤其大，引进率高，对其生物群和生态系统造成有害后果。基于综合分类方法，我们报道了在意大利北部亚得里亚海Sacca di Goro泻湖广泛分布的两种NIS双壳类（Cerastoderma edule和mytillopsis leucophaeata）。前一个物种的记录是意大利和地中海严格意义上的第一个记录，也是该物种入侵世界新地区的第一个确认证据，而后者的记录可能澄清了直到2008年入侵亚得里亚海北部的物种的分类不确定性。虽然它们的引入途径尚不确定，但它们最有可能是与蛤蜊幼虫或幼体一起进行种子活动而引入的，而白藻可能是通过附近种群的自然水流或自然/人为漂浮物或娱乐船只的污染群落而引入的。最后，尽管这两种新的NIS对当地的影响仍然不可预测，但C. edule可以达到非常高的密度，并具有生境工程师的结构作用，影响地表沉积物的分布，而M. leucophaeata可以污染和堵塞人为基质，并超越和取代底栖生物物种。因此，有必要在今后几年对该地区进行仔细监测，以评估这些新引进的后果。
