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. Although there are no certainties regarding their introduction pathways, C. edule was most likely introduced with seeding activities together with clam larvae or juveniles, while M. leucophaeata may have arrived through natural currents from nearby populations or amidst fouling communities of natural/anthropogenic floating objects or recreational vessels. Finally, although the local impact of these two new NIS is still unpredictable, C. edule can achieve extraordinarily high densities and has a structural role as a habitat engineer, influencing the distribution of surface sediments, while M. leucophaeata can foul and clog anthropogenic substrates and outgrow and replace benthic species. A careful monitoring of the area during the next years is therefore necessary to evaluate the consequences of these new introductions.

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。

Singkil peat swamp area is currently facing significant issues, including deforestation and the conversion of land into oil palm plantations. This situation threatens biodiversity and the wealth of genetic resources, potentially leading to the extinction of various terrestrial and aquatic species, including fish communities. Although there have been reports on the ichthyofauna in Singkil peat swamp, information regarding the genetic diversity of fish in this area is not available. Therefore, this study aimed to explore the use of DNA barcode method to validate the taxonomic status, as well as analyze the diversity and genetic relationships of fish found in Singkil peat swamp area, located in Aceh Province. A total of 123 DNA sequences were successfully obtained, leading to the generation of 88 haplotypes, comprising 34 species, 23 families, and 29 genera. The analysis of genetic distance was performed between various species. The results showed that the closest genetic distance of 4.04 % was between Ambassis macracanthus and Ambassis nalua, while the highest at 31.62 % was between Mystus nigriceps and Toxotes jaculatrix. Cyclocheilichthys apogon had the highest haplotype diversity with 6 haplotypes, while Caranx tille, Oreochromis niloticus, and Taenioides cirratus showed the lowest with 1 haplotype, respectively. Scientific data related to molecular genetics is crucial for effective fisheries resource management.

Singkil泥炭沼泽地区目前面临着严重的问题，包括森林砍伐和土地转化为油棕种植园。这种情况威胁到生物多样性和遗传资源的丰富性，可能导致各种陆生和水生物种，包括鱼类群落的灭绝。虽然有关于Singkil泥炭沼泽鱼类的报道，但没有关于该地区鱼类遗传多样性的信息。因此，本研究旨在探索利用DNA条形码方法验证亚齐省Singkil泥炭沼泽地区鱼类的分类地位，并分析其多样性和遗传关系。共获得123个DNA序列，产生了88个单倍型，包括34个种，23个科，29个属。对不同种间的遗传距离进行了分析。结果表明，大菱鲆与黄菱鲆的遗传距离最接近，为4.04%，黑桃与刺丝弓形虫的遗传距离最高，为31.62%。单倍型多样性最高的是Cyclocheilichthys apoogon，有6个单倍型，最低的是Caranx tille， Oreochromis niloticus和Taenioides cirratus，分别只有1个单倍型。与分子遗传学相关的科学数据对有效的渔业资源管理至关重要。

A new species of eelpout, Lycenchelys hexapora, is described based on the holotype obtained from the southern part of the Sea of Okhotsk, at a depth of 1040–1050 m. The new species is characterized by a low vertebral count for its genus (89), a black stomach, and six postorbital pores, that together distinguish it from all other congeners. The new species is the sixth representative of Lycenchelys in the Sea of Okhotsk. The possible closest relatives of the new species are distributed hundreds kilometers away from its locality, which hints to the extensive area of their common ancestor.

根据鄂霍次克海南部1040-1050米深度的完整模式，描述了一新种Lycenchelys hexapora。新物种的特点是其属的脊椎计数低（89），黑色的胃和六个眶后孔，这些将其与所有其他同系物区分开来。该新种是鄂霍次克海的第六个代表物种。这些新物种的近亲可能分布在距离其所在地数百公里的地方，这暗示了它们共同祖先的广阔区域。

Globalization has increased human movement, transforming ecosystems and introducing non-native species that threaten biodiversity, particularly in Antarctica. Due to its harsh climatic conditions, Antarctica has largely remained protected from biological invasions. However, rising human activity and environmental changes are facilitating the introduction of non-native species. The risks posed by species like Trichocera maculipennis are significant, as they can adapt and survive in new environments. This highlights the importance of understanding the adaptive factors that contribute to their success in order to prevent future invasions and protect the continent's unique ecosystem. The aim of this study was to quantify the wing morphological variation of T. maculipennis individuals associated with different Antarctic bases, analyzing this variation within a spatial and temporal context using morphometric tools. Samples were collected during Antarctic summer campaigns (2017/18 to 2019/20 and 2022/23) at the following research stations on King George Island: Artigas (Uruguay), Bellingshausen (Russia), Profesor Julio Escudero (Chile), and King Sejong (Korea). Morphometric analyses revealed changes in wing shape among study sites, with King Sejong individuals showing the most significant differences. Additionally, a temporal shift in wing size was observed, with specimens from 2017/18 and 2018/19 having larger average wings compared to those from 2019/20 and 2021/22. These results emphasize the importance of understanding the factors contributing to the success of non-native species to prevent future invasions and protect the unique ecosystem of Antarctica.

全球化增加了人类的流动，改变了生态系统，并引入了威胁生物多样性的非本地物种，特别是在南极洲。由于其恶劣的气候条件，南极洲在很大程度上受到保护，免受生物入侵。然而，人类活动的增加和环境的变化正在促进外来物种的引入。像maculpentrichocera这样的物种带来的风险是巨大的，因为它们可以在新的环境中适应和生存。这凸显了了解有助于它们成功的适应因素的重要性，以防止未来的入侵和保护非洲大陆独特的生态系统。本研究的目的是量化不同南极基地相关的斑羽羽翼个体的形态变异，并利用形态计量学工具分析这种变异在时空背景下的变化。在南极夏季活动期间（2017/18年至2019/20年和2022/23年），在乔治国王岛的Artigas（乌拉圭）、belingshausen（俄罗斯）、Julio Escudero教授（智利）和King Sejong（韩国）的研究站收集了样本。形态计量学分析揭示了研究地点之间翅膀形状的变化，世宗王个体表现出最显著的差异。此外，观察到翅膀大小的时间变化，2017/18和2018/19年的标本比2019/20和2021/22年的标本平均翅膀更大。这些结果强调了了解促成非本地物种成功的因素对防止未来入侵和保护南极洲独特的生态系统的重要性。

The Physalaemus deimaticus species group comprises four species distributed in high-altitude areas in southeastern Brazil. In this study we describe the tadpoles of two of these species, Physalaemus claptoni and P. deimaticus, and explore the body shape evolution in the group. Both species share external features with the other species of the group, but P. claptoni presents a larger and globular body, while P. deimaticus is quite similar to Physalaemus erythros, its sister species, sharing a P3 tooth row of the same length than P2, and submarginal papillae distributed in rows. The phylomorphospace analysis based on geometric morphometrics demonstrated that species of the P. deimaticus group exhibit a wide range of shapes, encompassing a great part of the variation found in the Physalaemus signifer clade. Thus, although ecomorphological correlations between shape and habitat type (i.e., lentic/lotic gradient) are evident at a narrower phylogenetic scale (i.e., within the P. deimaticus group), they become ambiguous when examined at a broader phylogenetic context (i.e., P. signifer group). Despite the general homoplasy scenario and the absence of important transformations in the evolution of body shape of the P. signifer group, the optimizations retrieved shape changes for the common ancestor of P. deimaticus and P. erythros, supporting their close relationship. Our results show that phylogenetic morphometric methods are effective for describing the evolution of tadpole shape, a set of traits not easily captured by discrete characters or linear measurements. Furthermore, the description of two tadpoles of Physalaemus increases knowledge of the larval diversity of the genus.

在巴西东南部高海拔地区分布有4个种。在本研究中，我们描述了其中两个物种，Physalaemus claptoni和P. deimaticus的蝌蚪，并探讨了该群体的体型进化。P. claptoni和P. deimaticus的外部特征与该组其他物种相同，但P. claptoni的身体较大且呈球形，P. deimaticus与其姊妹种Physalaemus erythros非常相似，P3齿列与P2齿列长度相同，边缘下乳头呈排状分布。基于几何形态计量学的形态空间分析表明，P. deimaticus类群的物种表现出广泛的形状，包括在Physalaemus符号分支中发现的大部分变异。因此，尽管形态和生境类型之间的生态形态学相关性（即，lltic /lotic梯度）在较窄的系统发育尺度上（即，在P. deimaticus组内）是明显的，但在更广泛的系统发育背景下（即，P. signifer组），它们变得模糊。尽管存在普遍的同形现象，而且在P. signifer类群的体型进化中缺乏重要的转变，但优化结果检索到P. deimaticus和P. erythros共同祖先的形状变化，支持它们之间的密切关系。我们的研究结果表明，系统发育形态计量学方法对于描述蝌蚪形状的进化是有效的，蝌蚪形状是一组不易被离散特征或线性测量捕获的特征。此外，对Physalaemus的两只蝌蚪的描述增加了对该属幼虫多样性的认识。

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.

在不同的时空尺度上，物种多样性的变化可能伴随着形态空间的变化。有证据表明，在整个地质尺度上，海洋无脊椎动物物种多样性和形态差异（morphodisparity）的变化是普遍存在的。本研究通过对智利中部4个地区的158个标本（33种21属）进行研究，估计了侏罗纪-白垩纪（J/K）过渡时期（从梯东纪到瓦兰吉尼纪）菊石的多样性和形态差异。对菊石进行侧面和正面拍摄，根据地标和半地标进行几何形态计量学分析。利用不同地质阶段的多元统计方法对所得形状进行了评估。结果表明，J/K转换期间的区系多样性变化与菊石形态空间的显著变化有关。值得注意的是，在泰东晚期和早期贝里亚时期之间，以及在早期和晚期贝里亚时期之间，观察到明显的形态差异变化。这项研究不仅记录了智利中部的动物更替，而且有助于我们理解灭绝脉冲如何在关键的进化转变中驱动形态创新或限制。

Summary - Nematodes from the family Thoracostomopsidae are ubiquitous in the World Ocean. Two species were found in subtidal bottom sedments off the eastern coast of the Kamchatka Peninsula. A taxonomic revision of the genus Trileptium has been provided. The new genus Neotrileptium gen. nov. was established and two new species Neotrileptium gracilis gen. et sp. nov. and Neotrileptium unicum gen. et sp. nov. are described. Neotrileptium gen.nov. shows all the main characters of Thoracostomopsidae, but differs from all known thoracostomopsids in the shape and position of the mandibular complexes (situated well forward in a spacious buccal cavity). The new species differ from others in this genus by a very large body size (more than 20,000 μm for N. unicum gen. et sp. nov. and more than 9000 μm for N. gracilis gen. et sp. nov.) and the presence of a pronounced circle of short cervical setae. Data on the nearly full length of the 18S rDNA, D1-D3 and D8-D10 domains of the 28S rDNA and ITS/5.8S and cox1 mtDNA nucleotide sequences were obtained. A phylogenetic analysis of the family Thoracostomopsidae was carried out using data on the nucleotide sequences of nuclear DNA of representatives of all three subfamilies (Thoracostominae, Enoplolaiminae, and Trileptiinae). The results of phylogenetic analysis did not confirm the monophyly of the last two subfamilies and many genera.

摘要-胸腹线虫科的线虫在世界海洋中普遍存在。在堪察加半岛东海岸的潮下底部沉积物中发现了两种。提供了三棱属的分类修订。建立了新属Neotrileptium gen. 11 .，并描述了新种Neotrileptium gracilis gen. et sp. 11和Neotrileptium unicum gen. et sp. 11两个新种。Neotrileptium gen.nov。显示了胸口科的所有主要特征，但在下颌复合体的形状和位置上与所有已知的胸口科不同（位于一个宽敞的颊腔中）。该新种与该属其他物种的不同之处是体型非常大（N. unicum gen. et sp. 11 .超过20,000 μm， N. gracilis gen. et sp. 11 .超过9000 μm），并且存在明显的短颈刚毛圈。获得了18S rDNA的近全长、28S rDNA的D1-D3和D8-D10结构域以及ITS/5.8S和cox1 mtDNA核苷酸序列的数据。利用3个亚科（胸口蝗科、Enoplolaiminae和Trileptiinae）代表的核DNA核苷酸序列数据对胸口蝗科进行了系统发育分析。系统发育分析结果未证实最后两个亚科和许多属的单系性。

Tropical Asia is home to the brackish/freshwater fish genus Brachygobius (Teleostei: Oxudercidae: Gobionellinae), commonly known as bumblebee gobies due to the alternating black and yellow/whitish bands on their bodies. The taxonomy of these miniature fishes is insufficiently studied, making their identification difficult. Here, we examined the species diversity of bumblebee gobies in Peninsular Malaysia by applying two molecular markers: the “barcode” fragment of the cytochrome c oxidase subunit I (COI) gene and a fragment of the nuclear rhodopsin (rho) gene. Twenty-four COI sequences and 20 rho sequences of Brachygobius were newly determined, combined and analysed with available data from both within and outside Peninsular Malaysia. A species delimitation approach conservatively revealed nine species of Brachygobius in our dataset. Conflicts with the current morphology-based classification were identified. Brachygobius sabanus and Brachygobius doriae are not reciprocally monophyletic, while Brachygobius nunus and Brachygobius kabiliensis each represent a species complex. Four species occur in Peninsular Malaysia, which we identified as Brachygobius xanthomelas, Brachygobius sabanus, Brachygobius nunus, and Brachygobius cf. aggregatus. A photograph of a specimen from each species in Peninsular Malaysia, along with habitat and distribution information, is provided.

热带亚洲是咸淡水/淡水鱼属虾虎鱼的家园（虾虎鱼目：鱼虎鱼科：虾虎鱼科），通常被称为大黄蜂虾虎鱼，因为它们身上有黑色和黄色/白色相间的条纹。这些微型鱼类的分类学研究不够充分，使它们的识别变得困难。本文采用细胞色素c氧化酶亚基I （COI）基因的“条形码”片段和核紫红质（rho）基因片段两种分子标记，对马来西亚半岛大黄蜂虾虎鱼的物种多样性进行了研究。新确定了24个COI序列和20个rho序列，并与马来西亚半岛内外的现有数据进行了组合和分析。物种划分方法保守地揭示了我们数据集中的9种短尾鱼。识别了与当前基于形态学的分类的冲突。sabanus和dororiae短尾虾不是相互的单系，而nunus和kabilibius分别代表一个物种复合体。马来西亚半岛有4种，分别为：Brachygobius xanthomelas、Brachygobius sabanus、Brachygobius nunus和Brachygobius cf. aggregatus。提供了马来西亚半岛每个物种标本的照片，以及栖息地和分布信息。

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.

本研究首先获得了产自广西南宁市横州的重要世界入侵花菜害虫Contarinia maculipennis的线粒体全基因组，并对其丝裂基因组进行了注释，分析了其tRNA二级结构，这是首次报道完整的cecidomiidae科tRNA二级结构集。同时，我们也对来自NCBI的乌鳢有丝分裂基因组序列进行了注释。通过与其他已鉴定和测序的瘿蚊种及外群的有丝分裂基因组重排特征进行比较，确定了瘿蚊重排特征和tRNA-Val二级结构的特殊性。通过对已鉴定的所有瘿蚊种及其外群的tRNA-Val二级结构的进一步整理和分析，结合分类、系统发育分析和重排特征，我们发现了瘿蚊科和瘿蚊科的一些规律，尤其是经有力验证的C. maculpennis的相关特征，这可能是揭示其广泛寄主辐射的潜在关键。

Species of the mythicomyiid genus Platypygus are mainly known from Eurasia, but are also found in Africa and North America, with only one species recorded from China. In this study, we describe two new species from China, Platypygus cangyuanensis sp. nov. and Platypygus wenkaii sp. nov. The DNA barcode sequences of both new species were generated. Species validity was supported by morphological characters, phylogenetic analyses, and genetic distance of COI barcodes. A key to all Chinese species of Platypygus is provided.

鸭嘴兽属（mythicomyiid genus Platypygus）的种类主要来自欧亚大陆，但在非洲和北美也有发现，只有一种来自中国。本文描述了两种来自中国的新种——沧源鸭嘴兽（Platypygus沧源鸭嘴兽）和文凯鸭嘴兽（Platypygus wenkaii sp.十一月），并生成了这两个新种的DNA条形码序列。COI条形码的形态特征、系统发育分析和遗传距离支持物种有效性。提供了所有中国鸭嘴兽种的钥匙。
