The taxonomic status of the Oxynoemacheilus from the Karınca and Havran streams in the north Aegean Basin was evaluated, and it was concluded that these populations contain a new species. The new species, Oxynoemacheilus kottelatisp. nov., is distinguished by a body with a marbled pattern, a deeper caudal peduncle, a shorter caudal peduncle, a wider interorbital distance, and a shorter middle caudal-fin lope. Oxynoemacheilus kottelatisp. nov. is differentiated from the closest species, O. marmaraensis, in possessing 51 nucleotide substitution sites, a genetic distance of 8.40%, the presence of an axillary lobe at the base of the pelvic fin (vs. absent), and a narrower median incision in the upper lip (vs. absent). Three species delimitation tests (ASAP, ABGD, and PTP) and phylogenetic analyses reinforce the validity of O. kottelatisp. nov. as a distinct species.
评估了北爱琴海盆地卡伦卡和哈夫兰溪流中 Oxynoemacheilus 的分类地位，得出的结论是这些种群包含一个新物种。新种名为 Oxynoemacheilus kottelatisp. nov.，其特征是身体有大理石花纹、尾柄较深、尾柄较短、眶间距较宽以及尾鳍中段较短。Oxynoemacheilus kottelatisp.nov.与最接近的物种 O. marmaraensis 的区别在于其拥有 51 个核苷酸替换位点，遗传距离为 8.40%，在骨盆鳍基部有一个腋叶（对无），以及上唇有一个较窄的中间切口（对无）。三个物种划分测试（ASAP、ABGD 和 PTP）和系统进化分析加强了 O. kottelatisp.

Based on the study of freshly-collected material and old museum specimens, we have solved a decades-old riddle surrounding the name Onychoglomeris herzogowinensis (Verhoeff, 1898). The southern Dinaric coastal species Glomeris herzogowinensis Verhoeff, 1898 is revived, while Onychoglomeris herzogowinensis australis Attems, 1935 and O. h. media Attems, 1935, are treated here as full species after returning the specific name to Glomeris Latreille, 1902, O. australis Attems, 1935, stat. nov. and O. media Attems, 1935, stat. nov. Besides the designation of lectotypes, we provide comprehensive illustrations, diagnoses, detailed remarks and a distribution map for all three species. In addition, DNA barcoding provided COI sequences for Glomeris herzogowinensis and Onychoglomeris australisstat. nov., along with the first barcoding data of one additional species of Onychoglomeris Verhoeff, 1906, O. ferraniensis Verhoeff, 1909 and two Glomeris species, the Balkan G. balcanica Verhoeff, 1906 and the trans-Adriatic G. pulchra Koch, 1847. The significance of historical specimens from natural history museums is briefly discussed.

A new species of the polyclad genus Prosthiostomum is described from the intertidal zone of the South China Sea, Huidong, China, based on morphological and molecular analyses. Prosthiostomum huidongensesp. nov. is characterized by i) few marginal eyes scattered between the marginal band and the cerebral eyes; ii) sucker located at two-thirds of the body length, being removed from the female gonopore by twice the distance between the male and female gonopores; iii) shallow male atrium with slightly ruffled inner wall, positioned approximately perpendicular to the body wall. Molecular phylogenetic analyses based on 28S rDNA sequence showed that the new species was nested in a clade composed of Prosthiostomum species. The uncorrected p-distance of COI between P. huidongensesp. nov. and other Prosthiostomum species ranged from 20.3 to 24.3%, and the high genetic divergence further supports P. huidongense as a new species.
根据形态学和分子学分析，描述了产于中国惠东南海潮间带的Prosthiostomum属的一个新种。Prosthiostomum huidongensesp.nov.的特征是：i）边缘带和脑眼之间散布着少量边缘眼；ii）吸盘位于体长的三分之二处，与雌性生殖孔的距离是雌雄生殖孔距离的两倍；iii）雄性心房较浅，内壁略有皱褶，位置与体壁近似垂直。基于 28S rDNA 序列的分子系统进化分析表明，该新物种嵌套在由 Prosthiostomum 物种组成的支系中。P.huidongensesp.nov.与其他前胸孢子虫物种之间未校正的 COI p-距离为 20.3% 至 24.3%，高度的遗传差异进一步支持 P. huidongense 为一个新物种。

The present study describes a new species within the genus Cultellus Schumacher, 1817 collected from the South China Sea. An integrative taxonomic approach incorporating morphological comparisons, geometric morphometrics and genetic analyses was used to identify and differentiate the new species. Cultellus exilissp. nov. is distinguished from its congeners by its slender, fragile and translucent valves, curved posteroventral margins and relatively large protractor scars. The geometric morphometric analyses, based on outlines data, indicated that samples of Cultellus exilissp. nov. clustered together and were distinctly separated from other species. Multiple species delimitation results, based on the mitochondrial COI gene, support the separation of Cultellus exilissp. nov. from its related congeners. Phylogenetic analyses of a nuclear (28S rRNA) and two mitochondrial (COI, 16S rRNA) genes using Maximum Likelihood and Bayesian Inference methods revealed that the species belongs to the genus Cultellus. The superfamily Solenoidea Lamarck, 1809, which includes the families Solenidae Lamarck, 1809 and Pharidae H. Adams & A. Adams, 1856, exhibits closer affinity to the family Hiatellidae Gray, 1824 than to Solecurtidae d’Orbigny, 1846. Furthermore, we found that the genus Siliqua was clustered alongside the genera Ensiculus and Phaxas as a sister clade, which contradicts the current systematics of the subfamily within the family Pharidae. This work highlights the utility of integrative taxonomy for species identification, recognition and phylogenetic investigation.

Centipedes of the genus Scolopocryptops Newport, 1844 are blind species mostly described from the New World and East Asia. In this study, a Japanese species, S. quadristriatus (Verhoeff, 1934), which is characterised by four longitudinal keels on the tergites, is re-described, based on the likely holotype preserved in the Zoologische Staatssammlung München and specimens newly collected from near the type locality. In addition, S. longisetosussp. nov., a new species that bears tergal keels like S. quadristriatus, is described from the Ryukyu Islands in Japan and Taiwan. Although the presence of four keels on tergites is unique to these two species, phylogenetic analyses using nuclear and mitochondrial markers showed that S. longisetosussp. nov. is not sister to S. quadristriatus. The obtained phylogeny indicates that the tergal longitudinal keels evolved in parallel within Scolopocryptops or that the presence of keels represents a plesiomorphic character of the clade containing these species.

Three new species of Rockacestus Caira, Bueno & Jensen, 2021 were recovered from arhynchobatid skates taken between 37°S–55°S in the Magellanic Province, Southwestern Atlantic Ocean. Rockacestus blasisp. nov. was found in Bathyraja macloviana (Norman, 1937), whereas Rockacestus magellanicussp. nov., and Rockacestus ottavianoisp. nov. were found in Bathyraja magellanica (Philippi, 1902). These species differ from their congeners in having a particular combination of anatomical features, including a moderate to highly folded bothridia, presence of a uteroduct, and a seminal receptacle. Cross-sections of mature proglottids were made for the first time in members of the genus. In addition, the microthrix pattern was described in detail, focusing on the distal bothridial surface, including the apical sucker and marginal loculi resulting in a common microthrix configuration with filitriches and small lanceolate, lingulate, and a particular kind of coniform spinitriches. The diagnosis of Rockacestus is revised to include several features exhibited by the new species. The distribution data of the species currently assigned to Rockacestus are compiled and updated. The finding of R. blasisp. nov., R. magellanicussp. nov., and R. ottavianoisp. nov. not only increases the number of members of Rockacestus in the Magellanic Province in the Southwestern Atlantic from one to four but also expands our knowledge of phyllobothriideans and their association with the softnose skates of the genus Bathyraja Ishiyama, 1958 in the Southern Hemisphere.

In addition, the microthrix pattern was described in detail, focusing on the distal bothridial surface, including the apical sucker and marginal loculi resulting in a common microthrix configuration with filitriches and small lanceolate, lingulate, and a particular kind of coniform spinitriches. The diagnosis of Rockacestus is revised to include several features exhibited by the new species. The distribution data of the species currently assigned to Rockacestus are compiled and updated. The finding of R. blasisp. nov., R. magellanicussp. nov., and R. ottavianoisp. nov. not only increases the number of members of Rockacestus in the Magellanic Province in the Southwestern Atlantic from one to four but also expands our knowledge of phyllobothriideans and their association with the softnose skates of the genus Bathyraja Ishiyama, 1958 in the Southern Hemisphere.","PeriodicalId":48677,"journal":{"name":"Zoosystematics and Evolution","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140749912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
