A new species of brittle star was collected in 2021 by the manned submersible “Fendouzhe” from the central rift zone deep waters, Philippine Sea, at a depth of 7729 m. It is described as Ophiuroglypha fendouzhe sp. nov., and is distinguished from its congeners based on the following features: slender arms, separated dorsal and ventral arm plates, overlapping large disc scales, and distally contiguous radial shields. We provide comprehensive descriptions of the external morphological features, including characteristics of the arm skeleton, and a phylogenetic analysis based on COI sequences. The interspecific genetic distance variation in the genus Ophiuroglypha found in this study was 3.89% to 24.25%. The new species constitutes the deepest known record for the genus Ophiuroglypha.

A new planthopper genus, Aodingus Chen & Li gen. nov. and three new species (A. hainanensis Chen & Li gen. et sp. nov., A. obscurus Chen & Li gen. et sp. nov. and A. cuongi Chen & Li gen. et sp. nov.) are described from China and Vietnam. The new genus is superficially similar to Procidelphax Bartlett, 2009 in general appearance in that the body is strongly dorsoventrally flattened. Distinctive features of the new taxon include broadly compressed body with vertex broad, apical margin broadly rounded, middle part concave, median and submedian carinae absent, frons broad and large, wider at base than at apex, forewing broad and long, aedeagus tubular, curved ventrally. A diagnosis for all species, illustrations and an identification key of new genus are provided. A key to the Chinese genera of Tropidocephalini is also provided.

A new subgenus of Orinda Kirkaldy, 1907, Montorinda subgen. nov., is described to accommodate two new species from southeastern Queensland, O. (Montorinda) eungellana sp. nov. from Eungella National Park and O. (Montorinda) montana sp. nov. from Mount Walsh National Park. The new species are compared to the other species of the genus and a new subgenus Scapulorinda subgen. nov. is described to accommodate Orinda (Scapulorinda) scapularis (Jacobi, 1928), leaving a single species in the subgenus Orinda: O. (Orinda) lucindae (Kirkaldy, 1906). Illustrations of the male holotype, a female paratype and male genitalia are provided for both new species as well as habitus and wing of O. (Scapulorinda) scapularis (Jacobi, 1928), the most closely related species, for comparison. The type series of the O. (Montorinda) montana sp. nov. was collected on Grevillea whiteana Mc Gill. (Proteaceae). The genus Orinda is only recorded from Queensland and now contains four species.

Two species of leeches were described from Georgia in the past, Dina ratschaensis Kobakhidze, 1958 from the Racha-Lechkhumi and Kvemo Svaneti region and Trocheta ariescornuta Grosser, Barjadze & Maghradze, 2021 from the Samegrelo-Zemo Svaneti region. Both species were the only known typical representatives of cave leeches in Georgia. Recently, two more species of the genus Dina R. Blanchard, 1894 have been found in karst caves in this country. These leeches are morphologically similar to D. ratschaensis, from which they differ in the shape of the reproductive system, primarily the shape of the cornua of the genital atrium and the shape and extension of the vasa deferentia and ovisacs, justifying the description of two new species, Dina imeretiensis Grosser, Barjadze & Maghradze sp. nov. from the Imereti region and Dina samegreloensis Grosser, Barjadze & Shavadze sp. nov. from the Samegrelo-Zemo Svaneti region. Data on the cave dwelling invertebrate communities in the studied caves are provided. Molecular data are provided, and a phylogenetic tree based on Cox1 sequences of Dina spp. and related genera is provided and discussed.

A new species of Bathynellidae is described from Colorado (USA). Hobbsinella gunnisonensis Camacho & Taylor sp. nov. displays a unique combination of morphological characters including seven-segmented antenna lacking medial seta on exopod, antennule slightly longer than antenna, three-segmented mandibular palp, four articles on endopod of thoracopods I to VII and five spines on sympod and three spines on endopod of the uropods. Partial sequences of cytochrome oxidase I (COI) and 18S have been obtained from several specimens of the new species. The mitocondrial and nuclear DNA data complement the traditional morphological taxonomic description support the validity of the new species. Molecular data for the Bathynellidae demonstrate the presence of two highly divergent genetic units, with the new species placed in the genus Hobbsinella. With the description of Hobbsinella gunnisonensis Camacho & Taylor sp. nov. and its molecular characterization, we discovered an interesting distribution of the genus, which occurs in both sides of the Continental Divide (Texas and Colorado) and different habitats.

A comprehensive checklist of Habenaria from Chapada dos Veadeiros, State of Goiás, was performed alongside morphologic and molecular phylogenetic studies, revealing three new taxa endemic to this region. A total of 61 taxa (59 species and two varieties) of Habenaria are recorded for Chapada dos Veadeiros, representing a two-fold increase compared to previous lists and comprising one of the greatest diversities of the genus in Brazil. Of this total, four taxa are locally endemic. Habenaria cultellifolia, until recently known only from the type collection, was rediscovered in the region after 127 years without records and represents this species’ only known extant population. Three proposed new taxa of Habenaria (H. minuticalcar J.A.N. Bat. & Bianch. sp. nov., H. proiteana J.A.N. Bat., A.A. Vale & Bianch. sp. nov., and H. lavrensis var. xanthodactyla J.A.N. Bat.& Bianch. var. nov.) are corroborated by molecular phylogenetic analyses based on nuclear and plastid markers. They are described, illustrated, tentatively assessed as threatened, and compared to phylogenetically and morphologically related species. Since some areas of this mountain range have not yet been floristically sampled, additional taxonomic novelties and new records are still expected in the future.

Amana, commonly known as ‘East Asian tulips’, has recently been found to harbor cryptic diversity due to recent field work and systematic investigations. In this study, we included 64 populations from all 12 Amana species and performed microscopic observations of their epidermal morphology. The leaf epidermis stomatal distribution of Amana can be characterized into three types: dense stomata (>10/per view or 263/mm2), sparse stomata (<10/per view or 263/mm2), and stomata absent. The epidermal cells of Amana can be characterized into four types: rectangular, long rectangular, nearly rectangular, and rhombic. The anticlinal wall morphology of the epidermal cells can be characterized into three types: linear, wavy, and nearly linear with mixed shallow waves. All the results were helpful for classification of Amana species. According to the reconstruction of ancestral characters analyses, the common ancestor of Amana is most likely to have leaves with dense stomata on both sides, and epidermal cells that have linear vertical walls.

The new nopine genus Roddenberryus gen. nov. is erected to include in total five species: three new species, R. kirk gen. et sp. nov. (male and female) from Costa Rica, R. spock gen. et sp. nov. (female) from Campeche, Mexico and R. mccoy gen. et sp. nov. (male) from Baja California Sur, Mexico, as well as two species previously misplaced in Caponina Simon, i.e., R. sargi (Pickard-Cambridge, 1899) gen. et comb. nov. from Guatemala and R. pelegrina (Bryant, 1940) gen. et comb. nov. from Cuba. A male specimen reported as C. sargi Pickard-Cambridge from Costa Rica by E. Kritscher (1957) is assigned to Roddenberryus kirk together with one female collected at the same locality. The new genus is characterized by the distally projected endites and a triangular, projected labium, a conformation unique among nopines; also by a triangular, very short, scaly gladius, serrula with interspersed multiple tooth rows, and a tarsal organ with strongly projected margins. Roddenberryus shares with Tarsonops Chamberlin the cracked tarsi and metatarsi, with multiple adesmatic joints intertwined on the cuticle and an unusual internal respiratory system with both posterior tracheae fused in a single trunk.
新建立的nopine属Roddenberryus gen. 11 .共包括5种:哥斯达黎加的R. kirk gen. et sp. 11 .(雄性和雌性)，墨西哥坎佩切的R. spock gen. et sp. 11 .(雌性)，墨西哥下加利福尼亚州南部的R. mccoy gen. et sp. 11 .(雄性)，以及之前在Caponina Simon的2种，即R. sargi (Pickard-Cambridge, 1899) gen. et comb。11月来自危地马拉和r.p elegrina (Bryant, 1940) gen. et comb。11月从古巴。e.k ritscher(1957)报告的哥斯达黎加的C. sargi Pickard-Cambridge雄性标本与在同一地点采集的一只雌性标本被分配给Roddenberryus kirk。新属的特点是远端投射的端尖和一个三角形的，投射的阴唇，一个独特的构象之间的nopines;也由一三角形的，非常短的，有鳞的剑鞘，小齿具散布的多齿行，和一跗骨器官具强烈突出的边缘。Roddenberryus和Tarsonops Chamberlin一样有开裂的跗骨和跖骨，有多个在角质层上缠绕的无骨关节和一个不寻常的内部呼吸系统，两个后气管融合在一个躯干上。

Roddenberryus shares with Tarsonops Chamberlin the cracked tarsi and metatarsi, with multiple adesmatic joints intertwined on the cuticle and an unusual internal respiratory system with both posterior tracheae fused in a single trunk.","PeriodicalId":12062,"journal":{"name":"European journal of taxonomy","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41966940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
