The understanding of the taxonomy, diversity, and evolutionary patterns of caviids in northwestern Argentina is still in the process of development. This paper presents new insights into the systematic and evolution of Orthomyctera andina (Rovereto, 1914), one of the most abundant species within Caviidae Fischer de Waldheim, 1817, in the fossil record of this region. A comprehensive anatomical description and taxonomic review of Orthomyctera andina in a phylogenetic context is provided. Moreover, it includes a redescription of the type specimen of Orthomyctera rigens (Ameghino, 1888). The taxonomical results confirm that O. andina belongs to a different genus: Orocavia (Kraglievich, 1932). The phylogenetic analysis further confirms the placement of both species within Caviinae Fischer de Waldheim, 1817. Orthomyctera andina is the sister taxon of the clade that includes Microcavia Gervais & Ameghino, 1880, Dolicavia Ameghino, 1916, Neocavia Kraglievich, 1932, and Orthomyctera Ameghino, 1889. It is supported by a combination of plesiomorphic characters (e.g. furrow opposite to hypoflexus/id in molariforms) shared with basal taxa and Dolichotinae Pocock, 1922 and derived characters (such as a terreced palate, external auditory meatus below the occlusal surface, length of p4-m1 shorter than length of m2-m3) shared with Caviinae. This study aims to elucidate the taxonomic status of these poorly known rodents and their relationships within Caviidae. Additionally, it incorporates a biogeographic analysis of caviomorph communities from the late Neogene in Argentina. [ABSTRACT FROM AUTHOR]

A fungal palynomorph corresponding to the fossil-species Lirasporis intergranifer R. Potonié & S.C.D. Sah, from the Middle Miocene lignite mine in Tomisławice (central Poland), is considered as the new combination Cancellidium intergraniferum (R. Potonié & S.C.D. Sah) G. Worobiec & E. Worobiec, comb. nov. The fossil-genus Lirasporis is treated as a synonym of the modern genus Cancellidium Tubaki. Cancellidium intergraniferum from the Miocene of Poland represents the first fossil record of Cancellidium outside Asia, the first record of this genus from Europe, and the northernmost known fossil occurrence of Cancellidium. Living representatives of Cancellidium seem to prefer warm and humid climates and, being aero-aquatic hyphomycetes, are usually associated with decaying woody remains in aquatic environments. A similar ecology is suggested for the fossil C. intergraniferum, which could be a reliable fungal non-pollen palynomorph proxy for palaeoclimatic and palaeoenvironmental reconstructions.

The widely treated order Capnodiales is one of the most important orders in the class Dothideomycetes. Recently, the order Capnodiales s. lat. was reassessed and split into seven orders (Capnodiales s. str., Cladosporiales, Comminutisporales, Mycosphaerellales, Neophaeothecales, Phaeothecales and Racodiales) based on multi-locus phylogeny, morphology and life strategies. In this study, two Arthrocatena strains isolated from sooty mould communities on the leaves of Tilia cordata and needles of Pinus nigra in southern Poland were analyzed. Multi-locus phylogenetic analyses (ITS-LSU-SSU-rpb2-tef1) along with morphological examination showed that they belong to Capnobotryella antalyensis, which represents a sister taxon to Arthrocatena tenebrosa. Capnobotryella antalyensis is a rock-inhabiting fungus described from Turkey. The following new combination is proposed: Arthrocatena antalyensis. Phylogenetic analyses also showed that Arthrocatena and related genus Hyphoconis, both known previously only from rocks, form a sister lineage to orders Cladosporiales and Comminutisporales. The new order Arthrocatenales and new family Arthrocatenaceae are proposed to this clade. Representatives of this order are extremophilic fungi that live on rocks and in sooty mould communities.

Abstract Of the early Eocene amber deposits known across the world, Belgian amber has been mostly absent from the relevant literature. We reinvestigated amber held in the palaeobotanical collection of the Royal Belgian Institute of Natural Sciences, Brussels, which derived from three localities in Belgium that originated from two geographical areas (Leval-Trahegnies and Orp-le-Grand). Using Fourier transform infrared (FTIR) spectroscopy we show the close chemical relationship of Belgian amber to the early Eocene Oise amber from the Paris Basin, and highlight the potential effect of weathering on the amber chemistry. The amber derives from a very similar botanical source as the Oise amber (Combretaceae or Leguminosae-Caesalpinioideae), but from different coeval basins. The two Leval-Trahegnies localities provided amber that exhibit different stages of weathering (heavily fissured and crazed, darkened) and lacking any inclusions. The Orp-le-Grand locality provided the least weathered amber, with one amber piece containing two inclusions: a mite and a new genus and species of hemipteran (Cativolcus uebruum gen. et sp. nov.), and a second one that preserved the impression of insect wings pressed into the surface.

Stephanorhynchus White, 1846 is a eugnomine weevil genus endemic to New Zealand, with 18 nominal taxa described within the genus. Examination of the type specimens of these taxa with greater understanding of related genera has led to the distinction of four well-defined genera from the species ascribed to the genus. These are the monotypic genus Pittosporobiusgen. nov., with type species P. crassus (Broun, 1880) comb. nov.; Moanusgen. nov., with type species M. lawsoni (Sharp, 1876) comb. nov., and including M. brevipennis (Pascoe, 1876) comb. nov. (= Stephanorhynchus griseipictus Broun, 1886 syn. nov.), M. nigrosparsus (Broun, 1893) comb. nov. (= Stephanorhynchus pygmaeus Broun, 1903 - syn. nov.) and M. tumulus Mazur and Brown sp. nov.

Summary: Three populations of Pauronemoides siddiqii n. gen., n. sp. were recovered from three different locations in northwestern and northern Iran from bark and soil samples. The new genus was described and illustrated based upon morphological and molecular characteristics. Pauronemoides n. gen. belongs to the family Paurodontidae and is characterised by the medium-sized body, asymmetrical knobs in stylet base, stem-like extension into intestine, post-vulval uterine sac (PUS) absent or rudimentary, different tail tip shape between sexes, and bursa enveloping tail or reaching to the tail end. The type species, Pauronemoides siddiqii n. gen., n. sp., is mainly characterised by 752-1281 μ m body length in females and 660-1085 μ m in males, six equally-sized lips, stylet 9-11 μ m long with asymmetrical knobs, six incisures in lateral fields forming five bands, three of which (two outers and one central) are wider, and variably lengthened stem-like extension projecting into the intestine. Vulva situated posteriorly (V = 87.7-91.7%), PUS absent. Conical tail with widely rounded end, having a small mucron at tip in females, males with conical tail ending to a narrower tip and bursa enveloping tail completely. The type species of the new genus was compared with all known species of the genera Prothallonema , Paurodontus , Paurodontoides and Paurodontella. Pauronemoides siddiqii n. gen., n. sp. resembles Prothallonema macrocellum and P. mucronatum by having the bulb extension penetrating into the intestine, dimorphism in tail shape of both sexes and bursa enveloping tail, and Paurodontella iranica by tail shape dimorphism between sexes and bursa ending near tail tip. Therefore, the above-mentioned species are transferred to the new genus as Pauronemoides macrocellus n. gen., n. comb. (= Prothallonema macrocellum), P. mucronatus n. gen., n. comb. (= Prothallonema mucronatum) and P. iranicus n. gen., n. comb. (= Paurodontella iranica). In addition to morphological comparisons, molecular phylogenetic analyses were performed using two sequences of small subunit (SSU), and three partial sequences of D2-D3 expansion segments of the large subunit (LSU) rDNA, and the resulting topologies were discussed.

Previous studies have shown that boletes are abundant and diverse in China, especially in tropical and subtropical regions. In the present study, morphological, ecological, host relationship, and a four-locus (28S, tef1, rpb1, and rpb2) molecular phylogenetic analyses were used to study the family Boletaceae in subtropical and tropical China. Four new bluing species are described from three genera, viz. Boletellus verruculosus (Chinese name疣柄条孢牛肝菌), Xerocomellus tenuis (Chinese name细柄红绒盖牛肝菌), Xer. brunneus (Chinese name褐盖红绒盖牛肝菌), and Xerocomus zhangii (Chinese name张氏绒盖牛肝菌). Moreover, the genus Nigroboletus is treated as a synonym of Xerocomellus, and a new combination, namely Xer. roseonigrescens (Chinese name玫瑰红绒盖牛肝菌), is proposed. [ABSTRACT FROM AUTHOR]

Background: The family Nemouridae, belonging to Plecoptera, comprises 21 genera and over 700 species found globally, with the greatest diversity observed in temperate regions. Nemoura Latreille, 1796 and Amphinemura Ris, 1902 are two largest genera of the family with the highest diversity in China. New information: Two new species of Nemoura Latreille, 1796 of the family Nemouridae, Nemoura exterclava Zhu, Rehman & Du sp. nov. and Nemoura cerciserrata Zhu, Du & Rehman sp. nov., are described and illustrated from the Nanling Mountains Region in Guangdong Province, southern China. The morphological characteristics of the new species are compared with related taxa. Additionally, the status of Indonemoura voluta Li & Yang, 2008, originally from Maoershan National Natural Reserve in Guangxi Zhuang Autonomous Region, was addressed and moved to the genus Amphinemura Ris, 1902 on the basis of newly-caught topotypes.

Aytoniaceae are one of the largest families of complex thalloid liverworts (Marchantiopsida), consisting of about 70 species, with most species being distributed in temperate areas. However, the phylogeny and evolution of the morphological character of Aytoniaceae are still poorly understood. Here, we employed two chloroplast loci, specifically, rbcL and trnL-F, along with a 26S nuclear ribosomal sequence to reconstruct the phylogeny and track the morphological evolution of Aytoniaceae. Our results reveal that Aytoniaceae are monophyletic, and five monophyletic clades were recovered (i.e., Asterellopsis-Cryptomitrium, Calasterella, Mannia, Reboulia-Plagiochasma, and Asterella). Asterella was divided into five clades (i.e., Asterella lindenbergiana, subg. Saccatae, subg. Phragmoblepharis, subg. Wallichianae, and subg. Asterella), except for Asterella palmeri, which is the sister of Asterellopsis grollei. Bayesian molecular clock dating indicates that the five primary clades within Aytoniaceae underwent divergence events in the Cretaceous period. Asterellopsis differentiated during the early Upper Cretaceous (c. 84.2 Ma), and Calasterella originated from the late Lower Cretaceous (c. 143.0 Ma). The ancestral Aytoniaceae plant is reconstructed as the absence of a pseudoperianth, lacking equatorial apertures, and having both male and female reproductive organs on the main thallus. At present, Asterellopsis consists of two species known in Asia and America with the new transfer of Asterella palmeri to Asterellopsis. A new subgenus, Asterella subg. Lindenbergianae, is proposed.

The genus Elegansovella Hirschmann, 1989 (Mesostigmata: Uropodina: Urodinychidae) is resurrected for species of the Uroobovella elegans-group. This genus differs from the other taxa of Uroobovella Berlese, 1903 sensu lato based on the shape of the idiosoma and the caudal and dorsal setae. Three species from the Uroobovella elegans-group are transferred to the genus Elegansovella, as E. pectintata (Hirschmann, 1973), comb. nov., E. pectinatasimilis (Hiramatsu, 1980), comb. nov. and E. serangensis (Hiramatsu, 1980), comb. nov. The other seven species from this species group are transferred to Monstrobovella gen. nov., as M. crustosa (Vitzthum, 1926), comb. nov., M. enodis (Hiramatsu, 1985), comb. nov., M. faceta (Hiramatsu & Hirschmann, 1978), comb. nov., M. facetaoides (Hiramatsu & Hirschmann, 1978), comb. nov., M. imadatei (Hiramatsu, 1980), comb. nov., M. incerta (Hiramatsu & Hirschmann, 1978), comb. nov. and M. incertaoides (Hiramatsu & Hirschmann, 1978), comb. nov. The new genus differs from Elegansovella by the shape of the idiosoma and the shape of marginal and dorsal setae. Six Monstrobovella species occur in the Oriental Realm and only one species is known from the Neotropical region. The present paper contains the description of a second Neotropical species of Monstrobovella (M. mancocapaci sp. nov.) which was found in Peru. The new species differs from its Neotropical congener in the dorsal and marginal setation. [ABSTRACT FROM AUTHOR]

Oreocharis leveilleana Fedde was collected in Ta-pin in 1910 and published in 1911. The collected location was verified within western Luodian County, Guizhou Province, China. However, there have been no records of the species' collection for more than 100 years since then. After extensive investigations by our research team on the type locality and its surrounding areas, we found that it is widely distributed in western Luodian County and eastern Wangmo County, Guizhou Province, China. During further research on the original literature, type specimens and type locality of O. leveilleana, the taxonomic position of O. leveilleana, which was once treated as a synonym of O. auricula (S.Moore) C.B.Clarke, was found to have a taxonomic problem. Through morphological research combined with geographical distribution analysis, it has been determined that it should belong to the genus Petrocodon Hance and it is the same species as P. coccineus (C.Y.Wu ex H.W.Li) Yin Z.Wang. According to the regulations and suggestions of the 2018 "International Code of Nomenclature for Algae, Fungi, and Plants (Shenzhen Code)", we propose and confirm a new combination -- Petrocodon leveilleanus (Fedde) X.X.Bai & F.Wen and treat P. coccineus as a synonym of the new combination. Due to its unique bright red flowers within Petrocodon, its original Chinese name has been retained. [ABSTRACT FROM AUTHOR]

The monospecific genus Tartessiberus was described in the year 2021 including a single species (T. cilbanus). However, its description relied solely on morphological and anatomical data. In the present work, we use a fraction of the mitochondrial DNA cytochrome oxidase subunit I (COI), 16S ribosomal RNA (16S rRNA) and the nuclear large ribosomal subunit (LSU) to clarify its validity through phylogenetic positioning. Knowledge of the distribution of this species is also improved by citing new locations and expanding the geographical range to approximately 200 km2. Additionally, a morphometric analysis of 259 shells is presented for comparisons with shells of the Iberus marmoratus complex and testing the power of conchological features as a tool for specimen identification. The relatively high conchological variability found for T. cilbanus, together with the discovery of populations with intermediate conchological features between T. cilbanus and other closely related taxa, suggest that the determination of this species should be based on genetic criteria. Our molecular analyses demonstrate that T. cilbanus belongs to the Iberus genus, and thus, we proceed to update its taxonomic status to Iberus cilbanus comb. nov., and, thus, to consider Tartessiberus from now on as a junior synonym of Iberus.

The marine microfilamentous green algal genus Okellya Leliaert & Rueness forms a distinct lineage of Cladophorales Haeckel, and currently contains only a single species, Okellya curvata (Printz) Leliaert & Rueness, originally described as Uronema curvatum Printz from Norway. Based on phylogenetic analyses of SSU and LSU rDNA sequences, we show that the Australian Uronema marinum Womersley also belongs to Okellya, and the species is transferred there as O. marina (Womersley) Wetherbee, comb. nov. We provide detailed observations of cultured material and show that O. marina (Womersley) Wetherbee, comb. nov. differs from O. curvata in the presence of pyrenoids, necessitating a revised circumscription of the genus Okellya and family Okellyaceae Leliaert & Rueness.

Specimen examinations and field observations revealed that Bupleurum smithii var. parvifolium was distinctly different from B. smithii var. smithii in umbel, leaf, and fruit morphology, but was very similar to B. commelynoideum var. flaviflorum. Based on these morphological evidences, the present study re-examined the taxonomic status of these taxa through morphological, cytological, and phylogenetic analyses. The results showed distinguishable features in the width of middle leaves and bracteoles of B. smithii var. parvifolium compared to B. smithii var. smithii. Morphological variation between B. smithii var. parvifolium and B. commelynoideum var. flaviflorum was continuous and overlapping. Notably, the chromosome number of B. smithii var. parvifolium was 2n = 14 (x = 7), consistent with B. commelynoideum var. flaviflorum, whereas B. smithii var. smithii was 2n = 64 (x = 8). Additionally, phylogenetic analyses revealed B. commelynoideum var. flaviflorum nested within B. smithii var. parvifolium, and that both were distant from the B. smithii var. smithii and B. commelynoideum var. commelynoideum. Based on the evidence above, the differences between B. smithii var. parvifolium and B. smithii var. smithii extend beyond the level of intraspecific variation, and B. commelynoideum var. flaviflorum is considered to be identical with B. smithii var. parvifolium. Hence. A new combination and status, B. parvifolium (Shan & Y.Li) Q.R.Liu & L.H.Wang, comb. et stat. nov. , is proposed. Furthermore, B. commelynoideum var. flaviflorum should be treated as a synonym of B. parvifolium. [ABSTRACT FROM AUTHOR]

Cryptic diversity is common among marine macroalgae, with molecular tools leading to the discovery of many new species. To assign names to these morphologically similar species, the type and synonyms have to be examined, and if appropriate, new species must be described. The turf‐forming red alga Polysiphonia scopulorum was originally described from Rottnest Island, Australia, and subsequently widely reported in tropical and temperate coasts based on morphological identifications. A recent study of molecular species delineation revealed a complex of 12 species in Australia, South Africa, and Europe. These species are placed in a taxonomically unresolved lineage of the tribe Polysiphonieae. The aim of this study was to resolve the genus‐ and species‐level taxonomy of this complex and related species using molecular and morphological information. Three morphologically indistinguishable species of the complex were found at the type locality of P. scopulorum, preventing a straightforward assignment of the name to any of the molecular lineages. Therefore, we propose a molecularly characterized epitype. Polysiphonia caespitosa is reinstated for the only species found in its type locality in South Africa. We describe seven new species. Only one species of the complex can be morphologically recognized, with the other eight species indistinguishable based on morphometric analysis. The studied complex, together with another seven species currently placed in Polysiphonia and two Bryocladia species, formed a clade distinct from Polysiphonia sensu stricto. Based on observations of Bryocladia cervicornis (the generitype), we describe our seven new species in the genus Bryocladia and transfer another nine species from Polysiphonia to Bryocladia.

Barleeiids are common marine microgastropods worldwide. Three species of Barleeia (Barleeia annamitica, Barleeia qilu n. sp. and Barleeia dunedini) found in the intertidal zone off the coast of China are described in this study. Morphological comparisons and species delimitation analyses using the universal mitochondrial COI gene sequence showed the distinctiveness of three species. Barleeia qilu n. sp., differentiated by its pointed apex and sutural channelling, was identified as a new species following morphological observation and phylogenetic analysis. Barleeia dunedini, previously considered as Ansola angustata (Pilsbry, 1901), has emerged as a distinct species and is probably the most widely distributed barleeiid in China. Barleeia annamitica, which has a broader distribution than previously recorded, is reported in China for the first time. Additionally, we propose to reassign Ansola angustata to the genus Barleeia based on the phylogram. Morphological illustrations, diagnoses, descriptions, and their approximate distribution along the coast of China are provided for each species. This study improves our understanding of the species composition, distribution and diversity of Barleeia in the intertidal zone of China. urn: lsid: zoobank.org:pub:7EFA6806-3A9E-40EC-A639-5AF4DB8D5CC7 [ABSTRACT FROM AUTHOR]

Alidus signatus Pic, 1926 is transferred from Mispila to Souvanna, and Souvanna signata (Pic, 1926), comb. nov. is proposed. The lectotype of Alidus signatus is designated.

The gender of the holotype of Alidus multilineatus Pic, 1925 is determined. New distributional records for Souvanna signata, Mispila curvilinea Pascoe, 1869, M. subtonkinea Breuning, 1968 and M. tenuevittata are provided. [ABSTRACT FROM AUTHOR]

This paper provides a comprehensive revision of the Palearctic plant bug genus Anapus Stål, 1858. Despite a limited number of included species, identification in this group remains challenging due to significant intraspecific polymorphism in the coloration and body proportions. To tackle this issue, confocal microscopy was used to study the male genitalia, and three-dimensional reconstructions of the aedeagus were obtained for all valid species. Our results reveal advantages of these techniques in visualizing small and complex genital structures over traditional methods of taxonomic imaging. A detailed study of the male and female genitalia resulted in finding novel characters allowing for unequivocal species recognition. The differential diagnosis for the genus and a key to all species are given. Habitus photographs, illustrations of male genitalic structures, scanning micrographs of morphological structures, host and distributional information are provided for all species. Anapus longicornis Jakovlev, 1882 is synonymized with Anapus pachymerus (Reuter, 1881) and a lectotype for the latter species is designated. Anapus americanus Knight, 1959 is transferred to the genus Myrmecophyes Fieber, 1870. [ABSTRACT FROM AUTHOR]

During a genetic analysis of western Atlantic Wrangeliaceae J.Agardh, specimens closely related to the generitype of Lophothamnion J.Agardh fell into a clade including the generitype of the earlier described Pleonosporium Nägeli, causing us to subsume the former genus. Two new species are described, P. novae-angliae G.W.Saunders & C.W.Schneider, sp. nov. for specimens from southern New England and New York, United States, formerly identified there as P. borreri (Smith) Nägeli, and P. ricksearlesii C.W.Schneider & G.W.Saunders, sp. nov. from Bermuda. The relationship of Pleonosporium with its sister genus Spongoclonium Sonder is discussed with the transfer of Spongoclonium australicum Womersley to Pleonosporium. Le genre australasien Lophothamnion J.Agardh se révèle génétiquement aligné avec Pleonosporium Nägeli (Wrangeliaceae, Spongoclonieae): nouvelles espèces de l'Atlantique occidental. Au cours d'une analyse génétique des Wrangeliaceae J.Agardh de l'Atlantique occidental, des spécimens étroitement liés au généritype de Lophothamnion J.Agardh sont tombés dans un clade comprenant le généritype de Pleonosporium Nägeli décrit précédemment, nous obligeant à englober le premier genre. Deux nouvelles espèces sont décrites, P. novae-angliae G.W.Saunders & C.W.Schneider, sp. nov. pour les spécimens du sud de la Nouvelle-Angleterre et de New York, États-Unis, anciennement identifiés là-bas sous le nom de P. borreri (Smith) Nägeli, et P. ricksearlesii C.W.Schneider & G.W.Saunders, sp. nov. des Bermudes. La relation entre Pleonosporium et son genre frère Spongoclonium Sonder est discutée avec le transfert de Spongoclonium australicum Womersley dans Pleonosporium. [ABSTRACT FROM AUTHOR]

Molecular systematic studies of the anthozoan class Octocorallia have revealed widespread incongruence between phylogenetic relationships and taxonomic classification at all levels of the Linnean hierarchy. Among the soft coral taxa in order Malacalcyonacea, the family Alcyoniidae and its type genus Alcyonium have both been recognised to be highly polyphyletic. A recent family-level revision of Octocorallia established a number of new families for genera formerly considered to belong to Alcyoniidae, but revision of Alcyonium is not yet complete. Previous molecular studies have supported the placement of Alcyonium verseveldti (Benayahu, 1982) in family Cladiellidae rather than Alcyoniidae, phylogenetically distinct from the other three genera in that family. Here we describe a new genus, Ofwegenum gen. nov. to accommodate O. verseveldti comb. nov. and three new species of that genus, O. coronalucis sp. nov., O. kloogi sp. nov., and O. colli sp. nov., bringing the total number of species in this genus to four. Ofwegenum gen. nov. is a rarely encountered genus so far known from only a few locations spanning the Indian and western Pacific Oceans. We present the morphological characters of each species and use molecular data from both DNA barcoding and target-enrichment of conserved elements to explore species boundaries and phylogenetic relationships within the genus.

Bupleurum jeholense Nakai (Apioideae, Apiaceae), originally found in the Wuling Mountain of China, was initially described as a species but later treated as a variety of B. sibiricum Vest ex Spreng. However, researchers have recently found that it is more closely related to B. chinense DC. In this study, we conducted morphological and phylogenetic analyses as well as chromosome counting to determine the taxonomic status of B. sibiricum var. jeholense (Nakai) Chu. Our results showed that B. sibiricum var. jeholense and B. chinense share common features (i.e., bracteoles 5 and stem solid) that distinguish both from B. sibiricum var. sibiricum. The chromosome number of B. sibiricum var. jeholense was found to be the same as in B. chinense (i.e., 2n = 12), whereas the chromosome number of B. sibiricum var. sibiricum was 64. A phylogenetic tree based on complete chloroplast genome data revealed a close relationship between B. sibiricum var. jeholense and B. chinense. Finally, B. sibiricum var. jeholense and B. chinense were mainly found to differ in plant height, number of stems, and middle stem leaves. Based on this evidence, we propose a new combination: Bupleurum chinense var. jeholense (Nakai) Q.R.Liu & L.H.Wang. [ABSTRACT FROM AUTHOR]

Brazil is known as a center of diversity for several plant families. Among these, Acanthaceae are especially diverse in the Cerrado, which is home to ca. 150 species, many of which are endemic. Recent field and herbarium studies of Ruellia of the Cerrado in Goiás and Distrito Federal have led to the discovery of 9 species new to science, which we formally describe as R. altoparadisensis, R. cataractae, R. ceciliae, R. chapadensis, R. glandulifolia, R. hatschbachii, R. lucindae, R. mellosilvae, and R. pinguicula. In addition to botanical illustrations, we provide information about their geographical distributions, habitats, phenologies, and preliminary conservation status. Species are discussed in the context of the Cerrado physiognomies and sub-biomes, which are delimited. We additionally propose one new combination (R. rosmarinus), two lectotypifications (R. pohlii and R. adenostachya), and an identification key to Ruellia species that occur Brazilian Cerrado.

Adalmus rugiceps (Broun, 1921) comb. nov. is transferred from the genus Plectomorphus Raff ray, 1898. Lectotypes are designated for Adalmus velutinus Reitter, 1885 and Dalmisus batrisodes Sharp, 1886. An identifi cation key, descriptions, habitus illustrations, diagnostic characters, a checklist, and distribution maps of Adalmus species are provided. [ABSTRACT FROM AUTHOR]

A new genus Plesiomedetera gen. nov., is described from Late Eocene Baltic amber. The genus is placed in the extant subfamily Medeterinae and includes five recognized and two doubtful species, all poorly described by Meunier in 1907–1908 and never reported again. Plesiomedetera flammea (Meunier, 1907), comb. nov. and P. mustela (Meunier, 1907), comb. nov. are described and illustrated, and a key to recognized species of this genus is compiled. The other eight extinct genera from Baltic amber are briefly reviewed, belonging to extant subfamilies ?Diaphorinae, Dolichopodinae, Medeterinae, Peloropeodinae and Sciapodinae, and a key to these genera is compiled. The following new combinations (comb. nov.) are proposed: Plesiomedetera decora (Meunier, 1907), P. elegantula (Meunier, 1907), P. vana (Meunier, 1907), P. lasciva (Meunier, 1907), P. lepida (Meunier, 1907), Medeterites atterraneus (Nazarov, 1994), M. gestuosus (Meunier, 1907), M. gulosus (Meunier, 1907), M. latipennis (Meunier, 1907), Palaeoargyra planipedia (Meunier, 1907), Palaeomedeterus praeconcinnus (Evenhuis, 1994), P. concinnus (Meunier, 1907), P. tertiarius (Meunier, 1907), Prohercostomus ciliatus (Meunier, 1907), P. devinctus (Meunier, 1907), P. gracilis (Meunier, 1907), P. minutus (Meunier, 1907), P. morbosus (Meunier, 1907), P. smicrus (Meuffels et Grootaert, 1999) and P. inumbratus (Meunier, 1907). Sciara pusilla Meunier, 1899 is considered nomen nudum, rather than unplaced species of Dolichopodidae. Dolichopus smicrus Meuffels et Grootaert, 1999 (unnecessary new name) is placed in synonymy with Prohercostomus minutus. In all, 53 recognized, 5 doubtful and 10 unplaced species from Baltic amber are listed. [ABSTRACT FROM AUTHOR]

Xenogaster Wasmann, 1891 is a Neotropical genus of termite-associated staphylinid beetles commonly found in nests of Nasutitermitinae termites. Due to morphological similarities and difficulties in their comparison, confusion often occurs among the species of Xenogaster and closely related genera such as Termitogaster Casey, 1889 and Termitomorpha Wasmann, 1894. The examination of the holotype of Xenogaster lineis Kistner, 2006, demonstrate that this specimen actually belongs to Termitogaster genus, leading to the proposal the transfer and new combination of this species, Termitogaster lineis (Kistner, 2006) comb. n. Additionally, examination of part of the paratypes of Xenogaster lineis revealed these specimens belong to a new species of the Termitomorpha genus, T. kistneri sp. n. here described. The results of these findings highlight the need of more taxonomic studies to resolve the ambiguity and imprecision in the diagnostic characters of closely related genera in Termitogastrina. This paper underscores the significance of revisiting and thoroughly re-examining type specimens and paratypes in order to ensure greater stability in the classification and nomenclature of insect taxa. To conclude, an updated key for Termitomorpha species and Neotropical Termitogastrina is also provided. [ABSTRACT FROM AUTHOR]

Ciliates serve as excellent indicators for water quality monitoring. However, their utilization is hindered by various taxonomic confusions. The ciliate genus Lacrymaria Bory de Saint-Vincent, 1824 is commonly found in different aquatic habitats, but its taxonomy has been sparsely investigated using state-of-theart methods. This study investigated two new Lacrymaria species from Nanhui Wetland, Shanghai, China, using living observation, protargol staining, and molecular phylogeny methods. Lacrymaria songi sp. nov. is 180-340 × 20-25 μm in size and possesses 12-16 somatic kineties, 1 terminal contractile vacuole, 2 macronuclear nodules, and 2 types of rod-shaped extrusomes. Lacrymaria dragescoi sp. nov. is distinguished from its congeners by its cell size of 210-400 × 25-35 μm, 14-17 somatic kineties, 1 terminal contractile vacuole, 1 macronucleus, and 2 types of rod-shaped extrusomes. Phylogenetic analyses based on SSU rRNA gene sequences indicate that Lacrymariidae is monophyletic but Lacrymaria is not. Additionally, a brief review of the genus Lacrymaria is provided in this study. We suggest that L. bulbosa Alekperov, 1984, L. lanceolata Kahl, 1930, and L. ovata Burkovsky, 1970 be removed from the genus and propose Phialina lanceolata nov. comb. and Phialina ovata nov. comb. for the latter two.

The taxonomy of the potamid crab genus Parvuspotamon Dai & Bo, 1994, with two species native to Yunnan province of southwest China, is revised based on morphological and molecular data. In order to stabilise the taxonomy of these species (and the genus), two separate genera are hereby designated: Parvuspotamon and Songpotamon gen. nov. While Parvuspotamon is restricted to P. yuxiense Dai & Bo, 1994, as a monotypic genus, P. dixuense Naruse, Chia & Zhou, 2018, is transferred to a new genus, Songpotamon gen. nov. In addition, two new species of Songpotamon gen. nov. are described herein: S. funingense sp. nov. and S. malipoense sp. nov. Songpotamon gen. nov. morphologically most resembles Parvuspotamon and Chinapotamon Dai & Naiyanetr, 1994, but can be distinguished by the combination of characters in the carapace, third maxilliped, thoracic sternites, and male first gonopod. The genetic data derived from the mitochondrial 16S rDNA also supports the monophyly of these new taxa. [ABSTRACT FROM AUTHOR]

Samples from coastal tropical waters of Central Sulawesi, Bangka Island and Bawean Island in Indonesia and from the Great Barrier Reef at Fitzroy Island in Queensland, Australia were analysed for species composition of diatom assemblages with a focus on Olifantiella. Whereas samples from Fitzroy Island littoral in Australia retrieved only one species of Olifantiella, in Poso Bay, Indonesia, we observed at least six species. All established taxa were documented with light (LM) and scanning electron microscope (SEM) and principal component analysis (PCA) analysis was used to compare the species, based on the basic valve parameters of length, width, length to width ratio and striae density. A new species of the genus Olifantiella, O. gondwanensis is described from Australia. In addition, we showed the distinct nature of O. pilosella var. rhizophorae permitting to species status. Particular attention is placed on girdle bands in this genus. [ABSTRACT FROM AUTHOR]
