Chronostratigraphy is the subfield of geology that studies the relative age of rock strata and that aims at producing a hierarchical classification of (global) divisions of the historical time-rock record. The 'golden spike' or 'GSSP' approach is the cornerstone of contemporary chronostratigraphic methodology. It is also perplexing. Chronostratigraphers define each global time-rock boundary extremely locally, often by driving a gold-colored pin into an exposed rock section at a particular level. Moreover, they usually avoid rock sections that show any meaningful sign of paleontological disruption or geological discontinuity: the less obvious the boundary, the better. It has been argued that we can make sense of this practice of marking boundaries by comparing the status and function of golden spikes to that of other concrete, particular reference standards from other sciences: holotypes from biological taxonomy and measurement prototypes from the metrology of weight and measures. Alisa Bokulich (2020b) has argued that these 'scientific types' are in an important sense one of a kind: they have a common status and function. I will argue that this picture of high-level conceptual unity is mistaken and fails to consider the diversity of aims and purposes of standardization and classification across the sciences. I develop an alternative, disunified account of scientific types that shows how differences in ontological attitudes and epistemic aims inform scientists' choices between different kinds of scientific types. This perspective on scientific types helps to make sense of an intriguing mid-twentieth-century debate among chronostratigraphers about the very nature of their enterprise. Should chronostratigraphers conventionally make boundaries by designating golden spikes, or should they attempt to mark pre-existing 'natural' boundaries with the help of a different kind of scientific type?

Venezuela’s diverse land ecosystems are grouped into four major regions (coast-islands, low plains, hills and mountains), ranging from sea level up to 4978 m. The Scarabaeinae (Scarabaeidae, Coleoptera) currently encompass 278 genera and 6837 species worldwide, but are poorly inventoried in Venezuela. We reviewed the literature and the material housed at the entomological collection of the Universidade Federal de Mato Grosso (CEMT), Cuiabá, Brazil, and found 32 genera and 149 species of dung beetles as certainly present in Venezuela. Twenty-four of these species are, as far as current knowledge goes, endemic to the country, while another 34 are restricted to Venezuela and the neighbouring countries of Colombia, Brazil, Trinidad and Tobago, and Guyana. Additionally, 36 species are deemed potential inhabitants of the country, whilst 14 others previously recorded in the literature as part of the Venezuelan fauna are here concluded not to be actually present there. Complete literature is listed for each genus and species, and information on type material, material examined, worldwide distribution, and Venezuelan records is also presented.

This is the first report of Euzophera vinnulella Neunzig (Pyralidae: Phycitinae) feeding on the bark of fig trees, Ficus carica (Moraceae), in northern California. We describe the immature stages, and provide images of the larva, pupal exoskeleton, and male genitalia from the reared adults. The immatures of E. vinnulella (and the genus Euzophera Zeller) are compared to those of Ectomyelois ceratoniae Zeller, or the carob moth. [ABSTRACT FROM AUTHOR]

- Abstract
Three Japanese conifer-infesting gall midges (Diptera: Cecidomyiidae), Aschistonyx eppoi Inouye on Juniperus chinensis var. globosa, Dasineura nipponica Inouye on Larix kaempferi, and Janetiella kimurai Inouye on Pinus parviflora are redescribed based on specimens kept in the collection of Naturalis Biodiversity Center, The Netherlands, in the collection of Kyushu University, Japan, and those newly obtained in 2021 and 2022 from their type localities in Japan. In the redescriptions, we refer mainly to morphological features not sufficiently given in the original descriptions. For A. eppoi, a genus Byakushincecis is created. We provide genetic data of the three species for future taxonomic and phylogenetic studies. In addition, we identified Byakushincecis eppoi infesting bonsai of Juniperus chinensis var. sargentii at a nursery garden in Saitama, Japan. These trees were intended for export to the EU.

The taxonomy of subulinid snails in Myanmar has been evaluated, resulting in the recognition of 40 species and subspecies across nine genera: Allopeas, Bacillum, Curvella, Glessula, Opeas, Paropeas, Rishetia, Tortaxis, and Zootecus. Nine species are re-described based on recently collected specimens, and two new species, Glessula mandalayensis Man & Panha, sp. nov. from Mandalay Region and Tortaxis cylindropsis Man & Panha, sp. nov. from Shan State are introduced. The genitalia and radula of Zootecus pullus was studied for the first time. This study also presents a comprehensive list of all subulinid species recorded to date from Myanmar. The type specimens and authenticated museum specimens have been illustrated with accompanying taxonomic remarks and nine species formerly assigned in Glessula are now placed in Rishetia: R. akouktoungensis, R. baculina, R. basseinensis, R. burrailensis maxwelli, R. kentungensis, R. limborgi, R. nathiana, R. pertenuis, and R. pertenuis major.

The history of collecting and cataloging Thailand's diverse herpetofauna is long-standing, with many specimens housed at the Thailand Natural History Museum (THNHM). This work aimed to assess the diversity of herpetofauna within the THNHM collection, ascertain conservation status of species, and track the geographical coverage of these specimens within the country. The THNHM collection boasts an impressive inventory, numbering 173 amphibian species and 335 reptile species. This collection reflects the substantial biodiversity within these taxonomic groups, rivaling the total number of herpetofauna species ever recorded in Thailand. However, the evaluation of their conservation status, as determined by the IUCN Red List, CITES, and Thailand's Wild Animal Preservation and Protection Act (WARPA), has unveiled disparities in the degree of concern for certain species, possibly attributable to differential uses of the assessment criteria. Notably, the museum houses a number of type specimens, including 27 holotypes, which remain understudied. Sampling efforts have grown considerably since the year 2000, encompassing nearly all regions of the country. This extensive and systematic collection of diverse herpetofauna at the THNHM serves as a valuable resource for both research and educational purposes, enriching our understanding of these species and their significance in the broader context of biodiversity conservation.

DNA sequences obtained from the isolectotype of Jania crassa, collected from Dusky Sound, Fiordland, New Zealand, have revealed the identity of this poorly understood taxon, and enabled comparison with modern material. The name Jania crassa has been previously widely applied in New Zealand and Australia. Data presented here show that Jania crassa differs from other species within the New Zealand region: of the eight species of Jania currently recognized, three are dichotomously branched, and two of these are known from southern New Zealand. Jania crassa can be distinguished from the smaller and epiphytic species of Jania in southern New Zealand, J. sphaeroramosa, on the basis of size and growth habit. Jania crassa appears to be an infrequently collected, possibly endemic species of southern New Zealand, with only one recent collection confirmed. Further collections and sequence data are needed to better understand the distribution of this species, particularly in neighbouring regions. [ABSTRACT FROM AUTHOR]

Abstract Kinglet Calyptura Calyptura cristata is one of the great enigmas of the South American avifauna. Endemic to an apparently tiny area of south-eastern Brazil, in the Atlantic Forest biome, the species was not definitely seen between sometime in the second third of the 1800s and 1996, when it was briefly rediscovered in submontane forest north-west of Rio de Janeiro. Since then, C. cristata has been reported several times, but without documentation and always by single observers. It is currently considered Critically Endangered by BirdLife International, and various authors have speculated that the species might already be extinct. Given the extreme paucity of knowledge of this species, we provide a complete inventory of museum material for Kinglet Calyptura - more than 100 specimens are listed, the majority held in European collections, almost doubling previous estimates made in the literature. Several are held in relatively small institutions, thereby suggesting that yet more specimens might still be identified or found. In addition, with the benefit of this large sample of material, we discuss morphological variation in the species and we hypothesise particularly about the appearance of male, female and juvenile plumages.

With diverse crowns, beautiful flowers, colorful fruits, and leaves of different colors in the four seasons, Sorbus L. has a very high ornamental value in landscape. The genus is also one difficult taxa for taxonomic research arising from the combined effects of hybridization, polyploidy and apomixis. In this study, the specimens preserved in National Plant Specimen Resource Center and the database of Global Plants were retrieved and carefully sorted out. Some key information such as herbaria, collectors, collecting sites, collection time were analyzed concretely to understand the collection sites and the distribution center of wild germplasm resources of Sorbus in China and construct the database of Sorbus in China, so as to provide references for the first general survey and collection of forest and grass germplasm resources in China. On the basis of clarifying the distribution range and habitat of Sorbus plant resources, we found that the species of Sorbus in China are the most abundant in the world and Sorbus species are mostly distributed in high-altitude areas. Especially, more than half of Sorbus species are distributed in the mountainous area of southwestern China, and multiple ploidy coexists in this area, which creates unique conditions for hybridization. Is it the key factor of rich species diversity of this genus? With this, the research status of Sorbus plants were further summarized, the problems existing in the study of molecular system biology, conservation biology, phytochemistry and resource development and utilization were pointed out, and the key issues to be paid attention to in the future research of Sorbus were put forward. Suggestions for future research on Sorbus were as follows: (1) We should focus on the study of process of hybridization on the basis of a solid phylogenetic framework; (2) Based on the comprehensive investigation of the wild germplasm resources of Sorbus in China, we should select the species with high ornamental value and study the molecular regulatory mechanisms of the response of Sorbus species to high-temperature stress in the summer in the low altitude areas by using the latest molecular biology techniques and methods, so as to provide a theoretical basis for the introduction and acclimatization of high-altitude species.

The family Promecheilidae Lacordaire, 1859 (= Perimylopidae St. George, 1939) has experienced a broad systematic redefinition and changes to its taxonomic composition during the last decade. Ten genera comprise this relatively small lineage, which is geographically restricted to the Holantarctic region. We further transfer the genus Dolphus Blanchard, 1847 from Tenebrionidae to Promecheilidae. The latter monotypic genus has been taxonomically problematic since its description due to the unique holotype being destroyed during its original species description. A full taxonomic catalog for the family is provided with type localities and references to synonymies, new combinations, and other nomenclatural changes. The catalog is illustrated with high-resolution images of type specimens housed in the Natural History Museum, London. [ABSTRACT FROM AUTHOR]

Background One difficulty in testing the hypothesis that the Australasian dingo is a functional intermediate between wild wolves and domesticated breed dogs is that there is no reference specimen. Here we link a high-quality de novo long-read chromosomal assembly with epigenetic footprints and morphology to describe the Alpine dingo female named Cooinda. It was critical to establish an Alpine dingo reference because this ecotype occurs throughout coastal eastern Australia where the first drawings and descriptions were completed. Findings We generated a high-quality chromosome-level reference genome assembly (Canfam_ADS) using a combination of Pacific Bioscience, Oxford Nanopore, 10X Genomics, Bionano, and Hi-C technologies. Compared to the previously published Desert dingo assembly, there are large structural rearrangements on chromosomes 11, 16, 25, and 26. Phylogenetic analyses of chromosomal data from Cooinda the Alpine dingo and 9 previously published de novo canine assemblies show dingoes are monophyletic and basal to domestic dogs. Network analyses show that the mitochondrial DNA genome clusters within the southeastern lineage, as expected for an Alpine dingo. Comparison of regulatory regions identified 2 differentially methylated regions within glucagon receptor GCGR and histone deacetylase HDAC4 genes that are unmethylated in the Alpine dingo genome but hypermethylated in the Desert dingo. Morphologic data, comprising geometric morphometric assessment of cranial morphology, place dingo Cooinda within population-level variation for Alpine dingoes. Magnetic resonance imaging of brain tissue shows she had a larger cranial capacity than a similar-sized domestic dog. Conclusions These combined data support the hypothesis that the dingo Cooinda fits the spectrum of genetic and morphologic characteristics typical of the Alpine ecotype. We propose that she be considered the archetype specimen for future research investigating the evolutionary history, morphology, physiology, and ecology of dingoes. The female has been taxidermically prepared and is now at the Australian Museum, Sydney. [ABSTRACT FROM AUTHOR]

- Abstract
Semisulcospira is a freshwater snail genus highly divergent in the ancient Lake Biwa, Japan, with a history of ~4 million years. Although the shell morphology, karyotype and molecular phylogeny of the genus have been well studied, the systematic status of several non-monophyletic species remains uncertain. In this study, we have evaluated the taxonomic accounts of the species previously identified as Semisulcospira decipiens , S. habei and relatives. We examined the genetic relationships using genome-wide SNP data and elucidated morphological variation among these using Random Forest classification. Morphological relationships between the name-bearing type of S. decipiens and the newly collected specimens were also evaluated. Morphological characteristics effectively discriminated between the nine genetic clusters, and the correlation among morphology and substrates was elucidated. We revised taxonomic accounts of S. decipiens , S. habei , S. arenicola , S. nakasekoae and S. ourensis and synonymised S. multigranosa , S. habei yamaguchi , S. dilatata under S. decipiens and S. fluvialis under S. nakasekoae. We also described two new species, Semisulcospira elongata sp. nov. and Semisulcospira cryptica sp. nov., and redefined two phylogroups of the lacustrine species as the Semisulcospira niponica -group and the Semisulcospira nakasekoae -group. Traits of the species examined exhibiting intraspecific variation in the different substrates and flow velocity may indicate the morphological and trophic adaptations. The habitat-related variation has certainly caused the taxonomic confusion of the lacustrine species. Lake drainage contributes to increasing the species diversity of the genus, generating ecological isolation between the riverine and lacustrine habitats. [ABSTRACT FROM AUTHOR]

When a new parasite species is identified, a name-bearing specimen or holotype is designated as its reference standard. For most acanthocephalans and nematodes, the holotype is male, a bias which lacks scientific justification. We propose ways of redressing this imbalance and achieving fuller representation of each species in museum collections. [ABSTRACT FROM AUTHOR]

- Abstract
Following the discovery of hominin fossils at Trinil (Java, Indonesia) in 1891 and 1892, Eug`ene Dubois named a new species, now known as Homo erectus. Although the main historical events are well-known, there appears to be no consensus regarding two important aspects of the naming of the species, including what constitutes the original publication of the name, and what is the name-bearing type specimen. These issues are addressed in this paper with reference to original sources and the International Code of Zoological Nomenclature. Our review confirms earlier studies that cite the published quarterly fieldwork report covering the 3rd quarter of 1892 as the original publication naming the species erectus. However, until recently, the correct publication year of 1893 has consistently been cited as 1892, and it has rarely been recognized that the author of the publication was anonymous, even though the author of the species is specifically named. Importantly, Dubois assigns all three hominin fossils found at Trinil up to that moment to the new species, explicitly stating that they belong to a single individual. The three fossils, a molar, a calotte, and a femur, therefore jointly constitute the original holotype. However, the femur most likely derives from younger strata than the other hominins and shows fully modern human-like morphology, unlike subsequently discovered H. erectus femora. Moreover, there is no consensus over the affinities of the molar, and if it is H. erectus rather than an extinct ape, there is no evidence that it belongs to the same individual as the calotte. Excluding these two fossils from the holotype, the calotte is the appropriate fossil to retain the role as name-bearing specimen.

- Abstract
Semisulcospira Boettger, 1886 is a freshwater snail genus divergent in Lake Biwa, Japan. Although recent taxonomic studies of the genus have arranged taxonomic accounts of many species in the lake, our knowledge of morphological traits has still been insufficient in S. reticulata Kajiyama & Habe, 1961, which belongs to the S. niponica-group in the genus. Among the various habitats of the lacustrine species, in addition, the species richness of this group in coastal sandy mud areas of the lake has not been completely clarified. In this study, we revisited the taxonomic account of S. reticulata and described a new S. niponica-group species, S. nishimurai sp. nov., from Lake Biwa by evaluating the genetic and morphological relationships within the group. The reconstructed maximum likelihood and singular value decomposition quartets trees, and ADMIXTURE analyses using genome-wide SNP data strongly supported the genetic distinctiveness of most S. niponica-group species. The Random Forest classification showed that S. reticulata possesses a unique, large protoconch without distinct keels, and that S. nishimurai sp. nov. is characterized by a small, less elongated teleoconch and tiny protoconch. The large protoconch of S. reticulata and the narrow radulae of S. reticulata and S. nishimurai sp. nov. suggest their specialization in life history and feeding habits, respectively. The discovery of the new species from sandy mud substrates highlights niche differentiation among Semisulcospira species, and provides new insights into the diversification of the genus in ancient lakes.

Historical DNA obtained from voucher specimens housed in natural history museums worldwide have allowed the study of elusive, rare or even extinct species that in many cases are solely represented by museum holdings. This has resulted in the increase of taxonomic representation of many taxa, has led to the discovery of new species, and has yielded stunning novel insights into the evolutionary history of cryptic or even undescribed species. Peromyscus mekisturus, is a critically endangered cricetid rodent endemic to Mexico and is only known from two museum specimens collected in 1898 and 1947. Intensive field work efforts to attempt to determine if viable populations still exist have failed, suggesting that this species is extinct or is nearing extinction. In addition, a recent study using mitogenomes demonstrated that P. mekisturus forms a well-supported clade outside the genus Peromyscus and hypothesized that this taxon is the sister group of the genus Reithrodontomys. Here, we used target enrichment and high-throughput sequencing of several thousand nuclear ultraconserved elements and mitogenomes to reconstruct dated phylogenies to test the previous phylogenetic hypothesis. We analyzed the holotype and the only other known specimen of P. mekisturus and museum samples from other peromyscine rodents to test the phylogenetic position of the species. Our results confirm that the only two specimens known to science of P. mekisturus belong to the same species and support the hypothesis that this species belongs to an undescribed genus of cricetid rodents that is sister to the genus Reithrodontomys. We dated the origin of P. mekisturus together with other speciation events in peromyscines during the late Pliocene – early Pleistocene and related these events with the Pleistocene climatic cycles. In light of our results, we recommend a taxonomic re-evaluation of this enigmatic species to properly recognize its taxonomic status as a new genus. We also acknowledge the relevance of generating genomic data from type specimens and highlight the need and importance of continuing to build the scientific heritage of the collections to study and better understand past, present, and future biodiversity.

Type specimens are valuable resources for investigating and exploring biodiversity on Earth, which has high academic and conservation value. Hemipteran insects are one of the most important and diverse groups in Insecta, and their type specimens have important reference value for many research fields. So far, the data on the type specimens of the Hemiptera in China have not been fully collated.Through extensive literature review, we have constructed a dataset of type specimens for the new species of hemipteran insects in China published from 1950 to 2017, which includes the data such as collection time, species author, specimen gender, preservation institution and geographical distribution. A total of 6583 type specimen records were collected, covering 3783 new species belonging to 1299 genera and 88 families. This dataset can provide help to the international community for conducting researches on taxonomy, biodiversity patterns, biota evolution, and pest management.

Neotropical Myotis have an accentuated phenotypic conservatism, which makes species delimitation and identification diffi- cult, hindering our understanding of the diversity, distribution, and phylogenetic relationships of taxa. To encourage new systematic reviews of the genus, a catalogue of the primary types and names is presented, current and in synonymy, for Neotropical Myotis. Currently 33 valid species (and three subspecies) are recognized, and their primary types are deposited in 12 scientific collections in the USA (30 types), Brazil (two types), England (two types), and France (one type). The names of 29 Neotropical Myotis species currently in synonymy were found. However, it is possible that some synonyms represent independent evolutionary lineages, considering recent results provided by taxonomic revisions. [ABSTRACT FROM AUTHOR]

Species of Ulva Linnaeus are nearly impossible to identify using morpho-anatomy due to their simple thallus structure and phenotypic plasticity. The current solution to this problem is to sequence DNA from field-collected specimens and match these sequences to those available in public DNA databases. However, because type specimens of many species have not been sequenced, the accuracy of these identifications is highly doubtful. Ulva rigida C.Agardh is reported to be one of the most widespread and ecologically important Ulva species, but these records are based on either morpho-anatomy or, more recently, on DNA sequences. High-throughput sequencing (HTS) was performed on the lectotype specimen of U. rigida from Cádiz, Spain to determine the correct application of the name. The analysis yielded its complete plastid genome. rbcL, tufA and ITS sequences from the lectotype specimen differed at the species level from all U. rigida sequences deposited in public databases. Instead, the lectotype sequences of U. rigida were identical or very similar to sequences identified as U. rotundata Bliding (referred to by some as U. pseudorotundata Cormaci, G.Furnari & Alongi) from Ireland and Portugal, but not to the holotype of U. rotundata from Italy, which was identical to U. lactuca L. HTS of the lectotype of U. lacinulata (Kützing) Wittrock from Lesina, Croatia, a species morphologically similar to U. rigida with macroscopic marginal teeth, also yielded a complete plastid genome, with sequences identical or highly similar to GenBank U. armoricana Dion, Reviers & Coat, U. 'laetevirens', U. 'rigida' and U. scandinavica Bliding. Since U. lacinulata is the oldest validly published name, it is the correct one to apply to the globally distributed species that was previously but incorrectly known as U. rigida. Based on this genetic evidence, U. rigida is restricted to European waters and confirmed by DNA sequences from Ireland, Portugal and Spain. This analysis shows that many barcode species identifications and taxonomic conclusions in the genus Ulva are incorrect. Ulva rigida was misapplied and is restricted to Atlantic Europe. Ulva lacinulata is the dentate species of Ulva distributed worldwide. Ulva rotundata is a heterotypic synonym of U. lactuca. [ABSTRACT FROM AUTHOR]

- Abstract
Correcting taxonomic misidentifications is crucial to ensuring the conservation and use of wild relatives in crop breeding programmes. Macrotyloma sar-garhwalensis R.D.Gaur & L.R.Dangwal, described as a new species from Uttarakhand (India) in 1997, is one such case of mistaken identity. Critical study of its protologue, type specimen, and field-grown plants indicated that this species was conspecific to Clitoria annua J.Graham. Molecular systematic studies using ITS 2 sequence regions further confirmed its closeness to C. ternatea L., than to any of the studied Macrotyloma species. This taxon, when considered as a wild relative of horsegram (M. uniflorum (Lam.) Verdc.), was given much importance in plant genetic resources programmes. This communication, besides revealing the differences of the taxon in question from Macrotyloma, brings out implications of this wrong taxonomic placement (under Macrotyloma). It also highlights the need for depositing type specimen in national repositories for ready access and strengthening the taxonomic base of botanists in general and agricultural scientists in particular.

A morphological description is provided for Chenopodium ucrainicum Mosyakin & Mandák (Chenopodiaceae / Amaranthaceae sensu APG), a new species allied to C. suecicum and C. ficifolium. At present this new species is reliably known from several localities in Ukraine (three areas in Kyiv city, one in Kyiv Region, one in Rivne Region), but it is probably more widespread, or could be even alien in Eastern Europe. Comparison of our plants with other taxa [such as C. suecicum (incl. C. neumanii, etc.), C. ficifolium, several morphotypes of C. album, as well as plants known as C. borbasii, C. missouriense (sensu stricto and sensu auct. europ.), C. lobodontum, etc.], demonstrated that C. ucrainicum is morphologically different from all these known and named taxa. It is also a late-flowering and late-fruiting species: in Kyiv fruits/seeds normally develop during late September – early November. This significantly reduces the possibility of gene flow and therefore hybridization with closely related diploid species, like C. ficifolium or C. suecicum, which usually flower and produce fruits earlier, mainly in July–August to early September. It also suggests that the new taxon is well isolated from its congeners and indeed represents a good species, not just one of weakly differentiated morphotypes that are so numerous in the C. album aggregate. To help researchers in identifying C. ucrainicum in the field and in herbaria, original illustrations are provided in the article and the Electronic Supplement. These illustrations include scanned images of the holotype (one specimen representing parts of one plant mounted on four herbarium sheets), field photographs showing plants and their parts at different stages of their development, and photomicrographs of fruits/seeds. Cytological and molecular data of the research team of B. Mandák (research in progress, detailed results to be published separately) demonstrated that C. ucrainicum is a B-genome diploid indeed related to C. suecicum and C. ficifolium. Supplementary Material. Electronic Supplement (Figures E1–E20, e1–e10) is available in the online version of this article at: https://ukrbotj.co.ua/archive/77/4/237.

CARNIVORA , *SPECIES - Abstract
For more than 130 years, the type locality of the Plains Spotted Skunk, Spilogale putorius interrupta (Rafinesque, 1820) has been accepted to be along the upper Missouri River. The species' description was based on a specimen observed by Constantine S. Rafinesque during his 1818 exploration of the Ohio River Valley, but Rafinesque never ventured into the animal's geographic range west of the Mississippi River, calling into question the type locality and, therefore, the identity of the taxon. We reconstruct Rafinesque's itinerary from his notes, publications, and correspondence and determine that Rafinesque probably observed the specimen on 20 September in Middletown, Kentucky, while traveling between Louisville and Lexington. He spent the day with John Bradbury, who participated in the 1811 Astor expedition up the Missouri River. On 1 April 1811, Bradbury collected the skin of a skunk, and evidence suggests that it was this skin that Rafinesque described. The type specimen of the Plains Spotted Skunk was obtained on the Missouri River flood plain in southern Chariton County or northern Saline County, Missouri, and this area should be considered the type locality for M. interrupta.

In this study we address the taxonomic identity of Hypudaeus syriacus, an arvicoline (Arvicolinae) from the Middle East which was described and named by Anton Brants in 1827. Although the type specimen is preserved, an exact conclusion regarding its identity was not achieved until recently. Currently, syriacus is reported as a synonym of Microtus socialis. Our analysis of the M1 occlusal pattern has convincingly demonstrated that the type clusters with the European snow vole Chionomys nivalis and does not match any species of Microtus from the Middle East. H. syriacus predates Arvicola nivalis Martins, 1842, which is in use for the European snow vole and is therefore the oldest available name for the species. Under the provision specified by Article 23.9.1 of the International Code of Zoological Nomenclature, syriacus is not a forgotten name (nomen oblitum) because several authors writing after 1899 used it as a valid name. Referring to the principle of priority, as stipulated in the Code, the valid name combination for the European snow vole is Chionomys syriacus (Brants, A. (1827). Het geslacht der muizen door Linneaus opgesteld, volgens de tegenswoordige toestand der wettenschap in familien, geslachten en soorten. Akademische Boekdrukkery, Berlyn [Berlin]). We restrict the type locality for syriacus to Mount Sanine in the Mount Lebanon range, northern Lebanon. [ABSTRACT FROM AUTHOR]

PYGMY marmoset ,NEW World monkeys ,SPECIES distribution ,TAXONOMY ,ANIMAL morphology ,ANIMAL genetics - Abstract
The pygmy marmoset, the smallest of the anthropoid primates, has a broad distribution in Western Amazonia. Recent studies using molecular and morphological data have identified two distinct species separated by the Napo and SolimõesAmazonas rivers. However, reconciling this new biological evidence with current taxonomy, i.e., two subspecies, Cebuella pygmaea pygmaea (Spix, 1823) and Cebuella pygmaea niveiventris (Lönnberg, 1940), was problematic given the uncertainty as to whether Spix’s pygmy marmoset (Cebuella pygmaea pygmaea) was collected north or south of the Napo and Solimões-Amazonas rivers, making it unclear to which of the two newly revealed species the name pygmaea would apply. Here, we present the first molecular data from Spix’s type specimen of Cebuella pygmaea, as well as novel mitochondrial genomes from modern pygmy marmosets sampled near the type locality (Tabatinga) on both sides of the river. With these data, we can confirm the correct names of the two species identified, i.e., C. pygmaea for animals north of the Napo and SolimõesAmazonas rivers and C. niveiventris for animals south of these two rivers. Phylogenetic analyses of the novel genetic data placed into the context of cytochrome b gene sequences from across the range of pygmy marmosets further led us to reevaluate the geographical distribution for the two Cebuella species. We dated the split of these two species to 2.54 million years ago. We discuss additional, more recent, subdivisions within each lineage, as well as potential contact zones between the two species in the headwaters of these rivers. [ABSTRACT FROM AUTHOR]

Following the discovery of hominin fossils at Trinil (Java, Indonesia) in 1891 and 1892, Eugène Dubois named a new species, now known as Homo erectus. Although the main historical events are well-known, there appears to be no consensus regarding two important aspects of the naming of the species, including what constitutes the original publication of the name, and what is the name-bearing type specimen. These issues are addressed in this paper with reference to original sources and the International Code of Zoological Nomenclature. Our review confirms earlier studies that cite the published quarterly fieldwork report covering the 3rd quarter of 1892 as the original publication naming the species erectus. However, until recently, the correct publication year of 1893 has consistently been cited as 1892, and it has rarely been recognized that the author of the publication was anonymous, even though the author of the species is specifically named. Importantly, Dubois assigns all three hominin fossils found at Trinil up to that moment to the new species, explicitly stating that they belong to a single individual. The three fossils, a molar, a calotte, and a femur, therefore jointly constitute the original holotype. However, the femur most likely derives from younger strata than the other hominins and shows fully modern human-like morphology, unlike subsequently discovered H. erectus femora. Moreover, there is no consensus over the affinities of the molar, and if it is H. erectus rather than an extinct ape, there is no evidence that it belongs to the same individual as the calotte. Excluding these two fossils from the holotype, the calotte is the appropriate fossil to retain the role as name-bearing specimen. [ABSTRACT FROM AUTHOR]

The pilumnoid Hoploxanthus cultripes Alcock, 1898, is currently recognized as a valid species in the genus Parapanope De Man, 1895 (Galenidae). The species, however, has never been figured, and the solitary type specimen from Karachi has never been studied since the original description. A re-examination of the holotype male in the Zoological Survey of India shows that it is in fact a senior synonym of Dentoxanthus iranicus Stephensen, 1946, previously known from Iran, Pakistan and northwestern India. The subfamily Parapanopinae Števčić, 2005, is also synoynymized under Dentoxanthinae Števčić, 2005, with the latter having priority. Résumé: Le crabe Pilumnoidea Hoploxanthus cultripes Alcock, 1898, est couramment reconnu comme une espèce valide dans le genre Parapanope De Man, 1895 (Galenidae).

Un ré-examen de l'holotype mâle lors du Zoological Survey of India montre qu'il s'agit en fait d'un synonyme senior de Dentoxanthus iranicus Stephensen, 1946, connu auparavant d'Iran, du Pakistan et du Nord-Ouest de l'Inde.

35. Understanding scientific types: holotypes, stratotypes, and measurement prototypes.

Bokulich, Alisa
- Abstract
At the intersection of taxonomy and nomenclature lies the scientific practice of typification. This practice occurs in biology with the use of holotypes (type specimens), in geology with the use of stratotypes, and in metrology with the use of measurement prototypes. In this paper I develop the first general definition of a scientific type and outline a new philosophical theory of types inspired by Pierre Duhem. I use this general framework to resolve the necessity-contingency debate about type specimens in philosophy of biology, to advance the debate over the myth of the absolute accuracy of standards in metrology, and to address the definition-correlation debate in geology. I conclude that just as there has been a productive synergy between philosophical accounts of natural kinds and scientific taxonomic practices, so too there is much to be gained from developing a deeper understanding of the practices and philosophy of scientific types.

Land snail surveys conducted in northern Laos between 2013 and 2014 have led to the discovery of a living population of Trichelix horrida (Pfeiffer, 1863). This species has never been recorded from specimens other than the types, and its distribution and anatomy have remained essentially unknown. The genitalia and radula morphology are documented here for the first time and employed to re-assess the systematic position of this species: the unique morphological characters of T. horrida are a penis similar in length to the vagina, a small and triangular penial verge, gametolytic organs extending as far as the albumen gland, head wart present, and unicuspid triangular radula teeth. The type locality of this species was believed to be from "Lao Mountains, Camboja," and is restricted herein to be Luang Phrabang Province, northern Laos. The assignment of species to either of three genera, Trichelix Ancey, 1887, Moellendorffia Ancey, 1887, and Moellendorffiella Pilsbry, 1905, based solely on information provided in their original descriptions is difficult. The type specimens of all nominal species presently placed in either of these three genera are examined and illustrated herein. Comparison with the primary type specimens will assist future revisions aiming to resolve the systematics of these taxa. In addition, we transfer Moellendorffia faberiana (Möllendorff, 1888) to the genus Moellendorffiella. [ABSTRACT FROM AUTHOR]

SUMMARY: In the red algal genus Gloiopeltis, five species (G. complanata, G. dura, G. frutex, G. furcata and G. tenax) are currently recognized, but genetic analyses have suggested considerably greater species diversity. Gloiopeltis specimens formed nine highly supported clades, six of which are morphologically referable to G. furcata. In order to identify the clade corresponding to true G. furcata, we examined the morphology and genetics of the type specimen of Dumontia furcata Postels & Ruprecht, the basionym of G. furcata, housed in the Herbarium of V.L. Komarov Botanical Institute (LE). A clade comprising the type and specimens from the northwestern to northeastern Pacific Ocean was determined to correspond G. furcata. We concluded that the type locality of G. furcata is Sitka, Alaska, based on the identity of haplotypes. We investigated the genetic divergence of populations within this species, using specimens covering most of its distributional range. We confirmed the merger of G. minuta and G. dura with G. furcata.

The aim of the present study is to update the checklist of vascular plants endemic to Mongolia using previous checklists, publications, herbarium collections, and field observations. The revised checklist includes 102 endemic taxa (95 species, five subspecies, and two nothospecies) from 43 genera and 19 families. The majority of endemic taxa were distributed in western and central Mongolia, and high endemic species richness was identified in four phytogeographical regions, namely Mongolian Altai, Khangai, Dzungarian Gobi, and Gobi Altai, which harbor 49, 27, 20, and 16 endemic taxa, respectively. For each endemic taxon, we compiled information about growth form, conservation status (if already assessed), phytogeographical distribution, and voucher specimens. Data on each taxon’s type specimen were also collected, and the majority of the type specimens were accessioned at the LE (58 taxa), MW (20 taxa), and UBA (7 taxa) herbaria.

Background: Neorautanenia is a small genus in the subtribe Glycininae within the tribe Phaseoleae in the family Fabaceae. It is distributed in southern and Tropical Africa. Historically, the genus is known to consist of three species, namely, N. brachypus, N. ficifolia and N. mitis; morphological data suggest that these should be reduced to two. Objectives: The aim of this article is to formally sink N. brachypus into the synonymy of N. mitis and to provide the correct typification, diagnostic features, diagnostic key, distribution maps, as well as illustrations of the morphological features of the two species. Methods: Observations were made on herbarium specimens housed at PRE. Morphological features were studied and measurements of characters recorded. Results: Neorautanenia mitis is extremely variable morphologically, so that several authors recognised many different variants, some of these as distinct species, including N. brachypus. Examination of numerous specimens, however, indicates that these are merely morphological and/or geographical variants of N. mitis. This observation prompted Verdcourt to place this taxon as a synonym of N. mitis; however, he reversed that decision 30 years later. It has become necessary to revert to the original decision. Conclusions: Neorautanenia brachypus is formally reduced to a synonymy of N. mitis and as a result the genus comprises only two species.

Robustly delimited species are of paramount importance, the identification of which relies on our ability to discern boundaries between one species and the next. This is not difficult to do when species are very distinct from one another. However, in recently evolved lineages where putative species may have relatively few diagnostic features (e.g., species complexes composed of very similar species, the boundaries between which are often unclear), defining species boundaries can be more challenging. Hence, the field of species delimitation has widely advocated the use of multiple lines of evidence to delimit species, particularly in species complexes. Excessive taxonomic confusion, often the result of species descriptions that shift through time (e.g., during revisionary work and regional treatments), can further complicate the search for diagnostic features in species complexes. Here, as a first step in robustly delimiting species boundaries, we quantify and describe morphological variation in the Castilleja pilosa species complex. We first infer the morphospace of the species complex and use fuzzy-clustering techniques to explore the morphological variation in the system. Next, we hypothesize the position of type specimens within that morphospace. In so doing, we aim to visualize the impact that regional treatments have had on the conceptualization of taxa through time. We find that there is limited morphological variation among members of this complex, and we determine that the morphological concept of these species have shifted through time and are no longer accurately represented by species descriptions.

The type species Paracondeellum dukouense (Tang & Yin, 1988) is redescribed based on syntype, and the lectotype and paralectotype are designated. The characters of the genus Paracondeellum are redefined, and the two known species are compared in detail. The Protura fauna of Hainan Island is mainly composed of species from the Oriental region, with 91% of the species belonging to the families Berberentulidae and Eosentomidae. [ABSTRACT FROM AUTHOR]

OROBANCHACEAE ,SPECIES ,TAXONOMY - Abstract
Robustly delimited species are of paramount importance, the identification of which relies on our ability to discern boundaries between one species and the next. This is not difficult to do when species are very distinct from one another. However, in recently evolved lineages where putative species may have relatively few diagnostic features (e.g., species complexes composed of very similar species, the boundaries between which are often unclear), defining species boundaries can be more challenging. Hence, the field of species delimitation has widely advocated the use of multiple lines of evidence to delimit species, particularly in species complexes. Excessive taxonomic confusion, often the result of species descriptions that shift through time (e.g., during revisionary work and regional treatments), can further complicate the search for diagnostic features in species complexes. Here, as a first step in robustly delimiting species boundaries, we quantify and describe morphological variation in the Castilleja pilosa species complex. We first infer the morphospace of the species complex and use fuzzy-clustering techniques to explore the morphological variation in the system. Next, we hypothesize the position of type specimens within that morphospace. In so doing, we aim to visualize the impact that regional treatments have had on the conceptualization of taxa through time. We find that there is limited morphological variation among members of this complex, and we determine that the morphological concept of these species have shifted through time and are no longer accurately represented by species descriptions.

The collection of the seven cyclophorid snail genera housed in the Natural History Museum, London (NHM), includes 95 available species-level names belonging to the genera Pterocyclos Benson, 1832, Cyclotus Swainson, 1840, Myxostoma Troschel, 1847, Rhiostoma Benson, 1860, Scabrina Blanford, 1863, Crossopoma Martens, 1891, and Pearsonia Kobelt, 1902. Lectotypes are here designated for twelve available species-level names to stabilise existing the nomenclature. A complete catalogue of these types, including colour photographs, is provided for the first time. After examining these type specimens, an unpublished manuscript name was found and is described herein as Pterocyclos anamullayensis Sutcharit & Panha, sp. n. [ABSTRACT FROM AUTHOR]

The land area of Laos is composed of a large variety of undisturbed habitats, such as high mountainous areas, huge limestone karsts and the lower Mekong Basin. Therefore, Laos is expected to have a high species diversity, especially for the land snails. However, with respect to research on malacology, Laos is probably the least well-researched area for land snail diversity in Indochina (including Laos) over the past few centuries. The handful of species lists have never been systematically revised from the colonial period to the present, so these classifications are outdated. Herein we present the first comprehensive annotated checklist with an up-to-date systematic framework of the land snail fauna in Laos based on both field investigations and literature surveys. This annotated checklist is collectively composed of 231 nominal species (62 'prosobranch' and 169 heterobranches), of which 221 nominal species are illustrated. The type specimens of 143 species from several museum collections and/or 144 species of newly collected specimens are illustrated. There are 58 species recorded as new to the malacofauna of the country, and two new replacement names are proposed as Hemiplecta lanxangnica Inkhavilay and Panha, nomen novum (Ariophantidae) and Chloritis khammouanensis Inkhavilay and Panha, nomen novum (Camaenidae). Four recently described species of the genus Amphidromus from Laos, "thakhekensis", "richgoldbergi", "attapeuensis" and "phuonglinhae" are synonymized with previously described species. In addition, thirteen nominal species are listed as uncertain records that may or may not occur in Laos. This annotated checklist may inspire malacologists to carry on systematic research in this region. [ABSTRACT FROM AUTHOR]

- Abstract
The collection of the tribe Eupitheciini from the Carpathian Basin in the Hungarian Natural History Museum was rearranged. Altogether 16571 specimens of 81 species were found in the former collection and unidentified accession material. All specimens were identified or their identification was checked, individual catalogue number was assigned to each of them and their data were recorded in a database. These data are published and all localities of each species are plotted on distribution maps. Brief diagnoses are given to all species as well as references to the major Hungarian faunistic works and identification guides. Collectors of the specimens are listed. The type specimens of Eupitheciini taxa occurring in the Carpathian Basin, deposited in the Hungarian Natural History Museum, are reviewed (54 specimens of 13 taxa). New synonymies are established: Tephroclystia graphata ab. brunnea ABAFI-AIGNER, 1906 is a synonym of Eupithecia graphata (TREITSCHKE, 1828), Eupithecia inturbata clujensis DRAUDT, 1933 is a synonym of Eupithecia inturbata (HÜBNER, 1807), and Tephroclystia isogrammaria transsylvanaria DANNEHL, 1933 is a synonym of Eupithecia haworthiata DOUBLEDAY, 1856. Particular new data to the Hungarian distribution of E. addictata DIETZE, 1908, E. nanata (HÜBNER, 1813) and E. sinuosaria (EVERSMANN, 1848) are added. Two specimens of E. scopariata (RAMBUR, 1833) from Budapest are presented and the possibility of their mislabelling is discussed. Occurrence of E. pulchellata STEPHENS, 1831 is not confirmed but cannot be excluded. In the Appendix references to the most important Hungarian works are given to each species, and a systematic list of the tribe is also included. With 46 figures, 81 maps and one table.

Background Neorautanenia is a small genus in the subtribe Glycininae within the tribe Phaseoleae in the family Fabaceae. It is distributed in southern and Tropical Africa. Historically, the genus is known to consist of three species, namely, N. brachypus, N. ficifolia and N. mitis ; morphological data suggest that these should be reduced to two. Objectives The aim of this article is to formally sink N. brachypus into the synonymy of N. mitis and to provide the correct typification, diagnostic features, diagnostic key, distribution maps, as well as illustrations of the morphological features of the two species. Methods Observations were made on herbarium specimens housed at PRE. Morphological features were studied and measurements of characters recorded. Results Neorautanenia mitis is extremely variable morphologically, so that several authors recognised many different variants, some of these as distinct species, including N. brachypus. Examination of numerous specimens, however, indicates that these are merely morphological and/or geographical variants of N. mitis. This observation prompted Verdcourt to place this taxon as a synonym of N. mitis ; however, he reversed that decision 30 years later. It has become necessary to revert to the original decision. Conclusions Neorautanenia brachypus is formally reduced to a synonymy of N. mitis and as a result the genus comprises only two species. [ABSTRACT FROM AUTHOR]

The Arion-Panin entomological collection belonging to the Research-Development Institute for Plant Protection contains material collected by Sergius Panin, George Arion and also pieces collected by Franz Salay. The collecting period covers the interval comprised mostly between 1930-1950, but the oldest pieces date back around 1890-1900.. The insects are pinned, their disposition inside the boxes is original and the conservation status is generally good, considering the age of the collection. Label data contain details of locality and date,. useful in terms of historical distribution records for the investigated specimens. The Coleoptera material was used in the elaboration of i) the first Romanian Coleoptera identification key and ii) the elaboration of four of the Coleoptera fascicules of the „Fauna of Romania" monographic series, Holotypes of two Coleoptera species described by Panin are conserved. The collection catalogue is presently lost. Writing a collection catalogue (first for Coleoptera) together with cleaning of the pieces and implementation of standard conservation measures would increase the value and lifespan of the collection.
