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.

本研究利用高通量测序技术，从巴基斯坦海域（63.95°E, 25.30°N）采集了黄颡鱼（Lutjanus fulvus）的有丝分裂全基因组，对其进行了鉴定，并下载了近缘种的有丝分裂全基因组，利用贝叶斯推理（Bayesian Inference， BI）方法构建了基于13个蛋白编码基因（PCGs）的系统发育树。L. fulvus全长16 493 bp，是一个典型的封闭环状双链DNA分子，G含量较低（16.2%），AT明显偏倚较高（52.8%）。基因组由37个基因组成：22个trna， 2个rnas， 13个PCGs和一个假定的控制区（D-loop）。在13个PCGs中，观察到4种终止密码子（TAA、TAG、AGA、T——），除COX1以GTG起始外，其余基因均以ATG起始密码子起始。BI树表现出一致的拓扑结构，表明与芦笋和芦笋关系密切。本研究为L. fulvus的有丝分裂基因组提供了有价值的基因组信息，增强了我们对Lutjanidae科有丝分裂基因组关系的认识，并为进一步探索Lutjanus属有丝分裂基因组提供了基础参考。此外，这些数据为黄颡鱼的分类、遗传多样性研究和保护管理提供了新的分子证据和理论基础。

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.

帽贝科，1850是帽贝的一个小群，广泛分布于从潮带到深海。该家族的单系性得到了形态特征和分子系统发育分析的支持，但家族内部的系统发育关系仍未得到解决。目前基于COI、16S、12S和H3 4个基因标记的系统发育分析显示西北太平洋lepeds是一个高度支持的进化支。Sagamilepeta sagamiensis是Lepeta caeca的姐妹种，根据形态特征和遗传距离可以与Lepeta属同义。隐branchia是一个独立的属，在根状形态和系统发育位置上都不同于Lepeta。此外，还发现了Limalepeta属的第二个未描述种，具有两栖类分布。根据其壳和舌的形态，给出了西北太平洋Lepetidae鉴定的关键。

We describe two new species—Holopogon hyalopterus sp. nov. And Molobratia zhangi sp. 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.

The Andaman Islands harbor a unique biodiversity that is distinct from Asian mainland India and Southeast Asia due to geographical isolation, high endemism, and varied ecological conditions. Among the diverse fauna, species of the genus Junonia are widely distributed across various habitats; however, their genetic diversity has not been explored using molecular approaches in this region. The present study aimed to generate mitochondrial COI gene DNA barcodes for Junonia species from the Andaman Islands on a broader scale. A total of 74 specimens, morphologically identified as four different species were analyzed. The intraspecific divergence ranged from 0.003 to 0.017, while interspecific nucleotide divergence among the four species ranged from 0.044 to 0.095. The maximum divergence (0.095) was observed between Junonia lemonias and Junonia atlites, and the lowest (0.044) between J. lemonias and Junonia hierta. The Phylogenetic tree was constructed using both Neighbor-Joining (NJ) and Maximum Likelihood (ML) methods which displayed nearly identical topologies, with COI sequences clustering cohesively by species. This study represents the first molecular documentation of Junonia genetic diversity in the Andaman Islands, establishing a critical baseline for future taxonomic and evolutionary investigations.

安达曼群岛拥有独特的生物多样性，由于地理隔离，高度地方性和不同的生态条件，它与亚洲大陆印度和东南亚不同。在动物群的多样性中，Junonia属的种类广泛分布于不同的生境；然而，他们的遗传多样性尚未利用分子方法进行探索。本研究旨在在更大范围内生成安达曼群岛朱诺尼亚种线粒体COI基因DNA条形码。对形态学鉴定为4个不同种的74个标本进行了分析。种内差异范围为0.003 ~ 0.017，种间差异范围为0.044 ~ 0.095。柠檬Junonia和atlites Junonia的差异最大（0.095），柠檬Junonia和hierta Junonia的差异最小（0.044）。采用邻域连接（NJ）和最大似然（ML）方法构建系统进化树，二者拓扑结构基本一致，COI序列按物种聚类紧密。该研究首次记录了安达曼群岛Junonia的遗传多样性，为今后的分类和进化研究奠定了重要的基础。

Listrura is a genus of small fossorial microcambevine catfishes presently comprising 14 species in three subgenera, two from tropical and one from subtropical Atlantic Forest of Brazil. Our field studies have revealed five new species from the subtropical area with unique morphological features. Herein we conducted a molecular phylogeny including all nominal species of the genus in which the new species are supported forming a clade, here described as a new subgenus sister to the subgenus Listrura from the tropical area. The five new species are diagnosed on the basis of osteological characters and external morphology. The new subgenus is separated from its sister group by a distance of about 500 km. This distributional gap is probably a result of insufficient field sampling efforts directed to the specialized biotopes of Listrura, consisting of leaf litter in the bottom of small brooks draining gently sloping terrain. However, the increasing environmental degradation in the region can easily reduce or eradicate these fragile environments.

Listrura是一个小的穴居微弯鲶属，目前包括3个亚属14种，2个来自热带，1个来自巴西的亚热带大西洋森林。在野外研究中，我们发现了五个亚热带地区的新种，它们具有独特的形态特征。在这里，我们进行了一个分子系统发育，包括所有的名义物种，其中新物种被支持形成一个分支，这里被描述为一个新的亚属姐妹，来自热带地区的Listrura亚属。根据骨学特征和外部形态对这5个新种进行了诊断。这个新的亚属与它的姊妹类群相距约500公里。这种分布上的差距可能是由于对Listrura特殊生物群落的野外采样工作不足造成的，Listrura生物群落是由排水平缓斜坡的小溪流底部的凋落叶组成的。然而，该地区日益严重的环境退化很容易使这些脆弱的环境减少或根除。

In Bethylidae, the ninth abdominal sternum or hypopygium is very important in the taxonomy of the family, because it is extremely variable in shape. Under this scenario, our objective is to compare the pregenital terminal segments and their muscles present in the abdomen of Bethylidae and standardize the terminology among the Hymenoptera. The function and position of the abdominal muscles and sclerites are described, the functions are discussed and the names are standardized. Our results indicate that the musculature and sclerites are few variable in the most part of the abdomen, however the ninth abdominal sternum presents the greatest changes related to its shape and associated muscles. Furthermore, based on our studies, we also infer that the sinergic movements of the ninth sterno-genital muscles are responsible for the protrusion, retraction and rotation of the genitalia, being responsible for the movements during the copula. In Pristocera, the muscles between S8 and S9 also promote secondarily the adduction and abduction of the ninth abdominal sternum. This phenomenon is interpreted as an example of exaptation. The understanding about the muscle morphology and its origin as well as its functionality are important because it may help conduct studies with other taxa in Hymenoptera with the same or different changes present in Bethylidae and arise hypotheses about the morphofunctionality in other groups.

在贝利亚科，第九胸骨或下胸骨在该科的分类学中非常重要，因为它的形状非常多变。在这种情况下，我们的目标是比较贝西利亚科腹部的生殖前末端节和它们的肌肉，并规范膜翅目昆虫的术语。描述了腹肌和腹膜的功能和位置，讨论了它们的功能，并规范了它们的名称。我们的研究结果表明，在腹部的大部分肌肉组织和硬膜几乎没有变化，但第九胸骨的形状和相关肌肉的变化最大。此外，根据我们的研究，我们还推断，第九块胸骨-生殖器肌肉的单能运动负责生殖器的前伸、后缩和旋转，负责性交过程中的运动。在胸大肌，S8和S9之间的肌肉也次要地促进第9胸骨内收和外展。这种现象被解释为兴奋的一个例子。了解膜翅目昆虫的肌肉形态及其起源和功能，有助于对其他膜翅目昆虫进行相同或不同变化的研究，并对其他类群的形态功能提出假设。

This study investigated population differences in whiting (Merlangius merlangus) from the Black Sea (BS) and the Sea of Marmara (SM) using truss morphometric analysis. Although whiting populations have been studied in major seas such as the Aegean, Mediterranean and Adriatic, this study fills a gap by exploring their morphological variation in diverse ecosystems, including inland seas like the SM. A total of 117 individuals were examined, with body shape variation assessed through a 17-point landmarks (yielding 38 truss network variables). Univariate ANOVA revealed that 33 out of 38 transformed truss morphometric parameters exhibited statistically significant variations across habitats. Principal component analysis (PCA) showed that the first two components (PC1 and PC2) accounted for 44.19 % and 10.34 % of the variation, respectively, cumulatively explaining 54.53 % of the total variance. Additionally, discriminant analysis revealed morphological separation between the BS and SM populations, and M. merlangus showed significant phenotypic heterogeneity between two Turkish seas.

Three (one new and two known) species of the genus Parahadronchus, found in natural areas of Vietnam, are characterized, including morphological descriptions, morphometrics, illustrations and molecular (18 S, 28 S) study. New data of Parahadronchus shakili and Parahadronchus siroii are provided. Parahadronchus pusillus sp. n. is distinguished by its 1.30–1.52 mm long body, lip region visibly expanded, 21–23 μm wide and offset by marked depression, buccal cavity 20–24 μm long with dorsal tooth apex at its middle and 2–4 (often 3) teeth on each subventral plate, neck 229–296 μm long, female genital system mono-prodelphic, slightly posterior (V = 50–56) and transverse vulva, tail very long and filiform (338–518 μm, c = 2.9–3.8, c’ = 17–23), and male unknown. Molecular analyses support the monophyly of Parahadronchus and identify fine major clades within the Mononchida tree, but their relationships significantly differ depending on the considered gene. The taxonomy of the genus is revised: emended diagnosis, list of species, key to their identification and a compendium of main morphometrics. Hadronchus kerangensis is regarded as a valid taxon and transferred to Parahadronchus.

本文对在越南自然地区发现的3种（1新种和2已知种）副ahadronchus进行了形态学描述、形态测量学、图解和分子（18s, 28s）研究。提供了沙基利副鸭嘴龙和siroii副鸭嘴龙的新资料。pusillus Parahadronchus sp. n.的特征是体长1.30-1.52 mm，唇区明显扩张，宽21-23 μm，有明显凹陷，口腔长20-24 μm，中间有背齿尖，每个腹下板上有2-4（通常为3）颗牙齿，颈部长229-296 μm，雌性生殖系统单前倾，稍后（V = 50-56）和横向外阴，尾巴很长，呈丝状（338-518 μm, c = 2.9-3.8, c ' = 17-23），雄性未知。分子分析支持副鸭嘴龙的单系性，并在单目目树中确定了精细的主要分支，但它们的关系因所考虑的基因而显着不同。对属的分类学进行了修订：订正的诊断、种表、鉴定要点和主要形态计量学简编。keranghadronchus被认为是一个有效的分类群，并被转移到副Hadronchus。

Maindroniidae is a rarely-encountered monogeneric family of Zygentoma, of which only four species are described so far. Recent surveys in the Atacama Desert have revealed in the hyperarid core an astonishing molecular and morphological diversity of these insects. The present work aims to provide the basis for a systematic taxonomic analysis of this diversity. The former Maindronia neotropicalis from Chile is redescribed in a new genus as Atacamus neotropicalis, along with a second new genus and species, Peruatacamus atunpacha from Peru. Neotropical Maindroniidae are separated from Old World Maindroniidae and placed in the new subfamilies Atacaminae and Maindroniinae respectively.

柱头蝇科是一种罕见的单属柱头蝇科，目前只发现了4种。最近在阿塔卡马沙漠的调查显示，在极度干旱的核心地带，这些昆虫的分子和形态多样性令人惊讶。本工作旨在为系统地对这种多样性进行分类分析提供基础。来自智利的前新热带Maindronia neotropicalis被重新描述为新属Atacamus neotropicalis，以及来自秘鲁的第二个新属和新种Peruatacamus atunpacha。新热带maindriniae科从旧大陆maindriniae科分离出来，分别归入Atacaminae亚科和maindriniae亚科。

Although Newportia is the genus of Scolopendromorpha with the greatest species diversity in the Neotropics, its diversity may be underestimated in certain areas of Brazil, such as the Pantanal Mato-Grossense, Brazilian Savanna (Cerrado) and Atlantic Forest. In this study, based on morphological and molecular data, three new species of Newportia are described: N. (Newportia) chamberlini sp. n., Newportia (Newportia) asulcata sp. n., and the first troglobitic species of the subgenus Tidops, N. (Tidops) eleonorae sp. n. N. (Tidops) eleonorae sp. n. was not included in the molecular analyses due to issues with DNA sequencing. However, its troglomorphic traits—unique to troglobitic species of Newportia and the subgenus Tidops—unequivocally support its status as a new species. Species delimitation analysis based on the mitochondrial marker COI recovered three lineages within N. (Tidops) balzanii in the Brazilian states of Mato Grosso do Sul and Mato Grosso. Both N. (Newportia) chamberlini sp. n. and N. (Newportia) asulcata sp. n. are recovered as different species, the former from Mato Grosso, and the latter from Bahia, within the “Caatinga” biome, a xeric region transitioning into the Atlantic Forest, both from Brazil. Phylogenetic analysis under maximum likelihood and Bayesian inference depicts a polyphyletic Tidops, with Newportia balzanii split into two clades based on geographical distribution. N. chamberlini sp. n. and N. asulcata sp. n. are recovered as sister species of the traditionally named but invalid Scolopendrides. The results of this work indicate that the diversity of the genus is underestimated and demonstrate that molecular tools are useful for the recognition of different lineages within species.

虽然Newportia属是新热带地区物种多样性最大的Scolopendromorpha属，但在巴西的某些地区，如Pantanal Mato-Grossense，巴西稀树草原（Cerrado）和大西洋森林，其多样性可能被低估。本研究基于形态学和分子数据，描述了3个新种：n (Newportia) chamberlini sp. n., Newportia (Newportia) asulcata sp. n.，以及tiops亚属的第一个跨地球物种n (Tidops) eleonorae sp. n., n (Tidops) eleonorae sp. n.由于DNA测序问题未纳入分子分析。然而，它的穴居物种Newportia和tidopa亚属特有的troglomerorphic特征明确地支持了它作为新种的地位。基于线粒体标记COI的物种划分分析在巴西南马托格罗索州和马托格罗索州恢复了n (Tidops) balzanii的三个谱系。n (Newportia) chamberlini sp.和n (Newportia) asulcata sp.作为不同的物种被恢复，前者来自马托格罗索州，后者来自巴伊亚州，在“Caatinga”生物群系中，一个向大西洋森林过渡的干旱地区，两者都来自巴西。在最大似然和贝叶斯推理下的系统发育分析描绘了一个多系的潮汐，巴尔扎尼新枝根据地理分布分为两个支系。N. chamberlini sp. N.和N. asulcata sp.被恢复为传统命名但无效的Scolopendrides的姐妹种。这项工作的结果表明，该属的多样性被低估，并证明分子工具是有用的，以识别不同的谱系在物种内。
