Brachynemurus bowlesi, sp. n. is a newly discovered myrmeleontid from the Sonoran Province, the northernmost subtropical region of Mexico. The new species fits within the Brachynemurus versutus subgroup, which now includes five species, all of them occurring in Mexico and the central and western United States. The new species may be identified by characteristics of the internal male genitalia, especially by a roof-like mediuncus, as well as the basal part of the 10th gonostyli, with paired processes in an acute angle and a shield-like expansion more evident in the dorsocaudal view. The formerly proposed synonymy of Brachynemurus mexicanus Banks, under B. versutus (Walker), is herein reinstated and supported.

Recently, based on light microscopy images, the tubercle structure on the seed surface of 100 Silene species was quantitatively described, including tubercle width, height, and curvature associated with general morphometric data. Curvature measures the rate of change of the tangent vector in a curve and can be calculated by the following methods described for Arabidopsis roots. Here, we apply curvature measurements to the SEM images of 40 Silene species from Türkiye, demonstrating that a quantitative analysis of tubercles can be made based on SEM images with similar results to optical photographs. The association of morphometric tubercle data allows for classification into six groups, five of them corresponding to described shapes: rugose (two groups), echinate, mammillate, and papillose, and a sixth group of tubercles plane on top. The curvature values vary between 20 and 200 mm−1 and differ among the morphological tubercle types described. The correlation of curvature values with other general measurements and morphological seed characteristics is investigated. Tubercle quantification not only is a useful tool for Silene taxonomy, but also provides the basis for the analysis of the genetic control and developmental effects on tubercle structure and shape in the seed surface.

Parasitic otitis is an inflammatory process that can affect the external to internal cattle ear, causing discomfort in animals, impairing performance, and even leading to animal death. The infection was initially associated with nematodes of the Rhabditis genus in tropical and subtropical regions. Currently, the nematode species described as associated with bovine otitis are Metarhabditis costai, Metarhabditis freitasi, and, more recently, M. blumi. It is worth highlighting that there is still a lack of robust information regarding the morphological details, ultrastructural aspects, and molecular biology data of these species. The Metarhabditis genus is composed of seven species and two more have recently been added. The objective of this study is to update the morphological data using advanced microscopy techniques to emphasize and clarify the main morphological differences between three species of Metarhabditis currently associated with parasitic otitis. Samples of inflammatory exudate were collected from four adult female Gir cattle (Bos taurus indicus) on a farm in Itabira, Minas Gerais state, Brazil. Specimens were analyzed using light microscopy and scanning electron microscopy. Two species, M. costai and M. freitasi, were morphologically identified, consistent with previous reports. Scanning electron microscopy revealed new structural characteristics of the nematode species involved in parasitic otitis compared with M. blumi obtained from the CGC Center. Significant differences were observed in the male posterior region, bursa, and tail. Molecular analysis was conducted to differentiate these three species, and it was observed that the species first associated with otitis formed distinct clusters compared to M. blumi. However, it is important to note that further studies are needed to genetically characterize species of the Metarhabditis genus.
寄生虫性中耳炎是一种炎症过程，可影响牛耳的外耳和内耳，造成动物不适，影响动物的生产性能，甚至导致动物死亡。这种感染最初与热带和亚热带地区的横纹肌属线虫有关。目前，被描述为与牛中耳炎有关的线虫种类有 Metarhabditis costai、Metarhabditis freitasi 以及最近出现的 M. blumi。值得强调的是，关于这些物种的形态细节、超微结构和分子生物学数据仍然缺乏有力的信息。拟线虫属由七个物种组成，最近又增加了两个物种。本研究的目的是利用先进的显微镜技术更新形态学数据，以强调和澄清目前与寄生性中耳炎相关的三个Metarhabditis物种之间的主要形态学差异。研究人员从巴西米纳斯吉拉斯州伊塔比拉一个农场的四头成年雌性吉尔牛（Bos taurus indicus）身上采集了炎性渗出物样本。使用光学显微镜和扫描电子显微镜对样本进行了分析。在形态学上确定了两个物种：M. costai 和 M. freitasi，与之前的报告一致。扫描电子显微镜显示，与从 CGC 中心获得的 M. blumi 相比，参与寄生性中耳炎的线虫具有新的结构特征。在雄性后部、法氏囊和尾部观察到显著差异。为了区分这三个物种，我们进行了分子分析，结果发现，与 M. blumi 相比，首先与中耳炎相关的物种形成了不同的群集。不过，需要注意的是，还需要进一步的研究来确定移虫属物种的遗传特征。

A new species of the genus Diploderma Hallowell, 1861 from Qiaojia County, Zhaotong City, northeastern Yunnan Province, China, is described. Phylogenetically, the new species is placed within the D. splendidum complex and has genetic distances of 7.3% and 7.5% from D. splendidum (Barbour & Dunn, 1919) sensu stricto and D. daduense Cai, Liu & Chang, 2024, respectively, based on the ND2 gene sequences. Morphologically, the new species closely resembles D. splendidum sensu stricto and D. daduense, however, it can be distinguished from D. splendidum sensu stricto by having a larger body size in males and relatively shorter limbs, and can be differentiated from D. daduense by having a relatively narrower head in males and relatively shorter forelimbs in males. In addition, the new species differs from D. splendidum sensu stricto and D. daduense by having different colorations, especially in the absence of transverse stripes on the dorsal head. This study further revealed that D. splendidum sensu lato is a complex containing multiple species and that more research is needed to clarify the taxonomy of the complex.
本文描述了产自中国云南省东北部昭通市巧家县的 Diploderma Hallowell, 1861 属的一个新种。根据 ND2 基因序列，该新种与 D. splendidum (Barbour & Dunn, 1919) sensu stricto 和 D. daduense Cai, Liu & Chang, 2024 的遗传距离分别为 7.3% 和 7.5%。从形态上看，新种与 D. splendidum sensu stricto 和 D. daduense 非常相似，但雄性体型较大，四肢相对较短，可与 D. splendidum sensu stricto 区分开来；雄性头部相对较窄，前肢相对较短，可与 D. daduense 区分开来。此外，新种与严格意义上的白芨和D. daduense的区别还在于体色不同，尤其是头部背面没有横条纹。这项研究进一步揭示了白芨属（D. splendidum sensu lato）是一个包含多个物种的复合体，需要更多的研究来明确该复合体的分类。

The Brazilian Atlantic Forest, one the five main biodiversity hotspots in the world, still houses many organisms that are rare and unknown to science, mostly concentrated in mountain ranges. Herein, we describe a rare new species of Cambeva from the Rio Tietê drainage at the Serra da Mantiqueira, exhibiting a caudal fin color pattern comprising a light-yellowish–white bar posteriorly edged by a black pigmented area. A similar color pattern was described for C. castroi, C. diabola, and C. melanoptera, also endemic to the Rio Paraná basin, and considered evidence of close relationships among these three species. However, other morphological characteristics highly suggest that the new species is not closely related to C. castroi, C. diabola, and C. melanoptera). Herein, we perform a molecular phylogenetic analysis using two mitochondrial genes and one nuclear gene, including all species with that bicolored caudal pattern. The analysis strongly supports the new species as a member of the alpha-clade, and therefore as distantly related to those three species belonging to the beta-clade, indicating that this color pattern has homoplastically arisen in Cambeva. The data reported here reinforce the urgent need for field studies to better understand the different evolutionary patterns found in the genus, since an intense process of environmental degradation is in course.
巴西大西洋森林是世界五大生物多样性热点地区之一，但这里仍有许多科学界未知的稀有生物，它们大多集中在山区。在本文中，我们描述了来自曼蒂凯拉山Rio Tietê排水系统的一种罕见的Cambeva新物种，该物种的尾鳍颜色图案由一条浅黄白色的条纹组成，条纹后部由黑色色素区镶边。同样是巴拉那河流域特有的 C. castroi、C. diabola 和 C. melanoptera 也描述了类似的颜色模式，被认为是这三个物种关系密切的证据。然而，其他形态特征高度表明，该新物种与 C. castroi、C. diabola 和 C. melanoptera 的亲缘关系并不密切。）在此，我们利用两个线粒体基因和一个核基因进行了分子系统发育分析，包括所有具有双色尾鳍图案的物种。分析结果强烈支持该新物种为 alpha 支系的成员，因此与属于 beta 支系的三个物种亲缘关系较远，表明这种颜色模式是在 Cambeva 中同源出现的。这里报告的数据加强了对实地研究的迫切需要，以更好地了解在该属中发现的不同进化模式，因为环境退化的过程非常激烈。

(1) Background: Although Physaloptera retusa is one of the most widespread species infecting reptiles in the Americas, numerous taxonomic problems and little genetic data are associated with it. To clarify the taxonomy of this species, we used an integrative approach. (2) Methods: Physaloptera retusa-infecting Erythrolamprus typhlus (snake) from the Pantanal wetlands, Brazil, was morphologically and genetically characterised (18S and 28S rDNA; COI mtDNA) and compared with conspecific sequences available in GenBank, from parasites of Tupinambis teguixin (lizard), using species delimitation methods. Type specimens of P. liophis were re-evaluated given its morphological similarities with P. retusa. (3) Results: The morphology of the present specimens was equal to that of P. retusa, in which the only difference from P. liophis was the relative position of the vulva. Species delimitation methods were more accurate for the COI dataset; all of them (except ABGD) indicated interspecificity among P. retusa sequences. However, a lack of morphological data or voucher material, associated with the deposited sequences, prevented more assertive conclusions. (4) Conclusions: The present results highlight the importance of a clear association between genetic data and morphology of the isolation source, or at least its adequate vouchering. Moreover, P. retusa may represent a species complex in cryptic speciation, since it is widespread and has low hosts specificity.

The necessity of the typification of the Apocynum L. s.l. (incl. Poacynum Baill. and Trachomitum Woodson) (Apocynaceae) species is crucial for future dogbane diversity estimations. Still, the original material of many taxa of the genus Apocynum s.l. is doubtful or remains to be discovered. This study’s topic is resolving a long-term taxonomic homonymy around the widely used binomial “A. sibiricum”. The misusing of the name “A. sibiricum” became a reason for long-term misunderstanding of the meaning of the binomial Poacynum sarmatiense (Woodson) Mavrodiev, Laktionov & Yu.E.Alexeev (A. sarmatiense (Woodson) Wissjul.; T. sarmatiense Woodson) and therefore for the misestimation of the Apocynum s.l. diversity in Russian and other Eurasian floras. Resolving this issue, here, we designate the lectotype of A. sibiricum Jacq. and the name “A. sibiricum Pall.” was validated within Poacynum as P. pallasianum Mavrodiev, Sytin, Laktionov & Vasjukov nom. nov. (Apocynum sibiricum auct., non Jacq.) with the lectotype selected from the original collections of Peter Simon Pallas.

The misusing of the name “A. sibiricum” became a reason for long-term misunderstanding of the meaning of the binomial Poacynum sarmatiense (Woodson) Mavrodiev, Laktionov & Yu.E.Alexeev (A. sarmatiense (Woodson) Wissjul.; T. sarmatiense Woodson) and therefore for the misestimation of the Apocynum s.l. diversity in Russian and other Eurasian floras. Resolving this issue, here, we designate the lectotype of A. sibiricum Jacq. and the name “A. sibiricum Pall.” was validated within Poacynum as P. pallasianum Mavrodiev, Sytin, Laktionov & Vasjukov nom. nov. (Apocynum sibiricum auct., non Jacq.) with the lectotype selected from the original collections of Peter Simon Pallas.","PeriodicalId":506775,"journal":{"name":"Taxonomy","volume":"17 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140980638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Specimens belonging to a new species in the genus Protocirrineris have been found during surveys along the southwestern coasts of the Netherlands. Protocirrineris stormae sp. nov, as described herein, were collected from the muddy bottom sediments in enclosed marine waterbodies and estuaries. This species is characterized by branchiae commencing from the first chaetiger and tentacular filaments arranged in two groups arising from chaetigers 2–3 that present one/two pairs of lobes, each bearing a single dorsal tentacle. From the current records of this species, it seems that P. stormae has an affinity for enclosed marine environments or parts of estuaries with minimal variability in salinity, higher transparency, and normal temperature regime. The discovery and study of this species contributes to a comprehensive characterization of benthic fauna in locations subjected to particular environmental stresses. Considering the extensive dataset available from the Southwestern Netherlands due to many years of sampling, it is plausible that P. stormae is a pseudo-indigenous species as there seem to be no records of similar or unknown Protocirrineris before 2013.

We report a new species of shearwater, Ardenna buchananbrowni sp. nov., from the Pliocene of New Zealand. It is both the smallest and oldest known diving member of the genus, demonstrating that this now abundant form of shearwater has had a long presence in southern oceans. Ardenna buchananbrowni sp. nov. is among the few extinct shearwaters described from the Southern Hemisphere and adds to an increasingly diverse seabird assemblage in the Pliocene of the region.
