Zoology, QL1-991
Abstract

The phytophagous scarab genus Macraspis MacLeay (Scarabaeidae, Rutelinae, Rutelini) is reviewed from the Brazilian Amazon region. Three new species are described and illustrated from the states of Amazonas, Pará, and Rondônia: M. buehrnheimi sp. nov., M. opala sp. nov., and M. phallocardia sp. nov. Two species, Macraspis fernandezi Neita-Moreno and M. oblonga Burmeister, are recorded for the first time in Brazil (new country records). Macraspis maculata crosarai Soula is a new synonym of Macraspis maculata Burmeister; hence this species no longer includes subspecies. Furthermore, Macraspis cincta parensis Soula, 2005 is deemed unavailable under the provisions of ICZN Articles 16.4.1 and 16.4.2. An illustrated key to 15 species and subspecies of Macraspis from the Brazilian Amazon enables identification of this speciose leaf chafer genus.

Abstract

Animal genomes vary widely in size, and much of their architecture and content remains poorly understood. Even among related groups, such as orders of insects, genomes may vary in size by orders of magnitude–for reasons unknown. The largest known insect genomes were repeatedly found in Orthoptera, e.g., Podisma pedestris (1C = 16.93 pg), Stethophyma grossum (1C = 18.48 pg) and Bryodemella holdereri (1C = 18.64 pg). While all these species belong to the suborder of Caelifera, the ensiferan Deracantha onos (1C = 19.60 pg) was recently found to have the largest genome. Here, we present new genome size estimates of 50 further species of Ensifera (superfamilies Gryllidea, Tettigoniidea) and Caelifera (Acrididae, Tetrigidae) based on flow cytometric measurements. We found that Bryodemella tuberculata (Caelifera: Acrididae) has the so far largest measured genome of all insects with 1C = 21.96 pg (21.48 gBp). Species of Orthoptera with 2n = 16 and 2n = 22 chromosomes have significantly larger genomes than species with other chromosome counts. Gryllidea genomes vary between 1C = 0.95 and 2.88 pg, and Tetrigidae between 1C = 2.18 and 2.41, while the genomes of all other studied Orthoptera range in size from 1C = 1.37 to 21.96 pg. Reconstructing ancestral genome sizes based on a phylogenetic tree of mitochondrial genomic data, we found genome size values of >15.84 pg only for the nodes of Bryodemella holdereri / B. tuberculata and Chrysochraon dispar / Euthystira brachyptera. The predicted values of ancestral genome sizes are 6.19 pg for Orthoptera, 5.37 pg for Ensifera, and 7.28 pg for Caelifera. The reasons for the large genomes in Orthoptera remain largely unknown, but a duplication or polyploidization seems unlikely as chromosome numbers do not differ much. Sequence-based genomic studies may shed light on the underlying evolutionary mechanisms.

Abstract

We provide an updated catalogue of the type material of the lepidopteran superfamily Papilionoidea deposited in the Zoological Museum of Hamburg (ZMH). We report 414 specimens labelled as “types” belonging to nine species (all of valid names), 74 subspecies (44 valid names and 30 synonyms), 59 invalid infrasubspecific names under the ICZN code, and 23 specimens of 16 “in litteris” (= unavailable) names. Out of the 414 specimens labelled as “types”, 171 specimens are primary types (8 holotypes/lectotypes and 163 syntypes) and 80 are secondary types; 120 specimens are infrasubspecific and hence invalid and are considered as “original specimens”; and 43 specimens are treated here as “Non-type” specimens (topotype). We present a full bibliography of the original descriptions and illustrations for all of these taxa, aiming to provide a comprehensive taxonomic guide to this collection.

Abstract

Zoological collections remain the main archive of animal biodiversity on Earth, and especially in times of large-scale declines of many groups represent important resources for biodiversity and conservation research. The most important individuals of these collections are the type specimens, which represent the original and unique reference for a species. While a full digitization of most museum collections currently remains utopic, lists of types are an essential resource for researchers to perform taxonomic revisions. Here, we provide an updated type catalogue of the lepidopteran superfamilies Hepialoidea, Cossoidea and Zygaenoidea deposited in the Zoological Museum of Hamburg (ZMH). In this paper, we report 259 specimens labelled as “types” belonging to 36 infrasubspecific taxa (invalid under the ICZN codes), 34 subspecies (16 of valid status) and 13 species (all of valid status). We present a full bibliography of the original descriptions and illustrations for all taxa, aiming to provide a comprehensive taxonomic guide to this collection.

Abstract

The genus Oplognathus MacLeay, 1819 is revised based on type material of two of the three described species and scattered additional material from several collections around the world. The diagnostic characters of the genus are confirmed, distinguishing it from other Brazilian Areodina mainly by: quadrangular clypeus with trilobate apex in males, rounded in females, extending beyond labrum in both sexes; mandibles with three distinct teeth; maxillae with six teeth; antenna with 10 antennomeres; 10 elytral striae; mesoventral process present; and asymmetrical parameres. The genus and all three species are redescribed, and the female of Oplognathus bahianus Ohaus, 1912 is described for the first time. We consider Oplognathus helmenreichi var. maculicollis Ohaus, 1914 an unavailable infrasubspecific taxon that is conspecific with Oplognathus helmenreichi Ohaus, 1905; its distribution is updated, and the different spelling of the specific epithet is discussed. A neotype is designated for Oplognathus kirbii MacLeay, 1819 since the holotype is currently considered lost. Additionally, an identification key and a distribution map are included.

Abstract

Grasshoppers, specifically those of the family Acrididae are known to have the largest genomes of all insects. However, less than 100 species of Orthoptera have their genome size estimated so far. In the present study, we measured the genome size of five acridid species belonging to the two subfamilies Oedipodinae and Gomphocerinae. All of the genomes measured are large and ranges between 1C = 11.31 pg in the female of Chorthippus dorsatus and 1C = 18.48 pg in the female of Stethophyma grossum. The latter represents the so far largest measured insect genome. We further provide a summary of genome size estimates available for Orthoptera.

Abstract

Introduction: The handover process in the emergency department (ED) is relevant for patient outcomes and lays the foundation for adequate patient care. The aim of this study was to examine the current prehospital to ED handover practice with regard to content, structure, and scope. Methods: We carried out a prospective, multicenter observational study using a specifically developed checklist. The steps of the handover process in the ED were documented in relation to qualification of the emergency medical services (EMS) staff, disease severity, injury patterns, and treatment priority. Results: We documented and evaluated 721 handovers based on the checklist. According to ISBAR (Identification, Situation, Background, Assessment, Recommendation), MIST (Mechanism, Injuries, Signs/Symptoms, Treatment), and BAUM (Situation [German: Bestand], Anamnesis, Examination [German: Untersuchung], Measures), almost all handovers showed a deficit in structure and scope (99.4%). The age of the patient was reported 339 times (47.0%) at the time of handover. The time of the emergency onset was reported in 272 cases (37.7%). The following vital signs were transferred more frequently for resuscitation room patients than for treatment room patients: blood pressure (BP)/(all comparisons p < 0.05), heart rate (HR), oxygen saturation (SpO 2) and Glasgow Coma Scale (GCS). Physicians transmitted these vital signs more frequently than paramedics BP, HR, SpO 2, and GCS. A handover with a complete ABCDE algorithm (Airway, Breathing, Circulation, Disability, Environment/Exposure) took place only 31 times (4.3%). There was a significant difference between the occupational groups (p < 0.05). Conclusion: Despite many studies on handover standardization, there is a remarkable inconsistency in the transfer of information. A “hand-off bundle” must be created to standardize the handover process, consisting of a uniform mnemonic accompanied by education of staff, training, and an audit process.

Abstract

A new genus of coprophagous beetle, Evanesternum gen. n. (Hydrophilidae: Sphaeridiinae: Megasternini), is described in order to accommodate Cercyon (Acycreon) pulsatus d’Orchymont, 1937 from the Republic of South Africa and the Democratic Republic of Congo. A detailed description is provided along with habitus photographs, line drawings and SEM micrographs of relevant diagnostic characters. The new genus possesses the tribal synapomorphies of Megasternini but bears several unique morphological characters which are discussed in detail. The morphology of the remaining three species classified in the subgenus Acycreon d’Orchymont, 1942 (i.e. C. punctiger Knisch, 1921, C. collarti d’Orchymont, 1942 and C. apiciflavus Hebauer, 2002), is illustrated in order to provide evidence that Acycreon is an assemblage of morphologically dissimilar and likely not related species. An identification key to the Megasternini genera and subgenera known from the Republic of South Africa is presented.

Abstract

The representatives of the genus Cercyon Leach occurring in the Greater Antilles are reviewed. Ten species are recorded, of which five are described here as new: C. gimmeli sp. n. (Dominican Republic), C. armatipenis sp. n. (Dominican Republic), C. taino sp. n. (Dominican Republic), C. sklodowskae sp. n. (Jamaica) and C. spiniventris sp. n. (Dominican Republic). Diagnoses and detailed distributional data are also provided for C. floridanus Horn, 1890 (distributed in southeastern United States of America and Cayman Islands), C. insularis Chevrolat, 1863 (endemic to the Antilles) C. praetextatus (Say, 1825) (widely distributed in the New World incl. Greater Antilles), C. quisquilius (Linnaeus, 1761) (an adventive species of Paleartic origin) and C. nigriceps (Marshall, 1802) (an adventive species probably of Oriental origin). Cercyon armatipenis, C. gimmeli, C. taino form a group of closely related species only distinguishable by male genitalia and DNA sequences. A key to the Great Antillean Cercyon is provided and important diagnostic characters are illustrated. The larvae of C. insularis and C. taino were associated with adults using COI barcode sequences, illustrated and diagnosed. Full occurrence data, additional images and COI barcode sequences were submitted to open access on-line depositories in an effort to provide access to complete data.

Abstract

The pelidnotine scarabs (Scarabaeidae: Rutelinae: Rutelini) are a speciose, paraphyletic assemblage of beetles that includes spectacular metallic species (“jewel scarabs”) as well as species that are ecologically important as herbivores, pollinators, and bioindicators. These beetles suffer from a complicated nomenclatural history, due primarily to 20th century taxonomic and nomenclatural errors. We review the taxonomic history of the pelidnotine scarabs, present a provisional key to genera with overviews of all genera, and synthesize a catalog of all taxa with synonyms, distributional data, type specimen information, and 107 images of exemplar species. As a result of our research, the pelidnotine leaf chafers (a paraphyletic group) include 27 (26 extant and 1 extinct) genera and 420 valid species and subspecies (419 extant and 1 extinct). Our research makes biodiversity research on this group tractable and accessible, thus setting the stage for future studies that address evolutionary and ecological trends. Based on our research, 1 new species is described, 1 new generic synonym and 12 new species synonyms are proposed, 11 new lectotypes and 1 new neotype are designated, many new or revised nomenclatural combinations, and many unavailable names are presented. The following taxonomic changes are made: New generic synonym: The genus Heteropelidnota Ohaus, 1912 is a new junior synonym of Pelidnota MacLeay, 1819.

Abstract

The Neotropical scarab beetle genus Mesomerodon Ohaus (Scarabaeidae: Rutelinae: Rutelini) is distributed in the western (lowland) Amazonian region from Colombia to Bolivia. Based on our research, the genus includes three species including a new cryptic species from Ecuador. We use niche modeling to predict potential suitable habitat and identify environmental factors associated with the distribution of Mesomerodon species. We characterize the genus, provide a key to species, diagnose each species, describe a new species, provide spatial and temporal distributions, and discuss distributions of the species in relation to Amazonian landscape biodiversity.

The family Cerasommatidiidae was proposed by Brèthes in 1925 for his new genus Cerasommatidia from Brazil, described as an intermediate taxon between Endomychidae and Coccinellidae (Coccinelloidea). This group was neglected for decades until 1994 when the resemblance of Cerasommatidia with the eupsilobiine genus Ibicarella was noticed, and Cerasommatidiidae was synonymized with Eupsilobiinae (Endomychidae). Based on the newly discovered material from the Neotropical and Afrotropical regions with clear resemblance to Cerasommatidia and Ibicarella, the phylogenetic placement of these taxa and new allied genera was reassessed based on phylogenetic analyses of molecular, morphological and combined datasets. The data were analysed under Bayesian (BI), maximum likelihood (ML) and parsimony (MP) frameworks. Our results support the restoration of Cerasommatidiidae as a distinct family in Coccinelloidea. Close affinity of Cerasommatidiidae with Coccinellidae, Eupsilobiidae and Mycetaeidae is recovered and the sister-relationship to Mycetaeidae is highly supported. Ibicarella is found to be a junior synonym of Cerasommatidia. Three new genera and six new species are described and illustrated: Yamuy gen. nov. (type species, Y. marginatus sp. nov.; and Y. constratus sp. nov.) and Karumbe gen. nov. (type species, K. geiseri sp. nov.; K. brethesi sp. nov. and K. pakaluki sp. nov.) from the Neotropics and Mahavelo gen. nov. (type species, M. madagasus sp. nov.) from Madagascar.

Abstract

The availability of public genomic resources can greatly assist biodiversity assessment, conservation, and restoration efforts by providing evidence for scientifically informed management decisions. Here we survey the main approaches and applications in biodiversity and conservation genomics, considering practical factors, such as cost, time, prerequisite skills, and current shortcomings of applications. Most approaches perform best in combination with reference genomes from the target species or closely related species. We review case studies to illustrate how reference genomes can facilitate biodiversity research and conservation across the tree of life. We conclude that the time is ripe to view reference genomes as fundamental resources and to integrate their use as a best practice in conservation genomics., Trends in Genetics, 39 (7), ISSN:0168-9525

Abstract

Scarab beetles (Scarabaeidae) are a diverse and ecologically important group of angiosperm-associated insects. As conventionally understood, scarab beetles comprise two major lineages: dung beetles and the phytophagous Pleurosticti. However, previous phylogenetic analyses have not been able to convincingly answer the question whether or not the two lineages form a monophyletic group. Here we report our results from phylogenetic analyses of more than 4,000 genes mined from transcriptomes of more than 50 species of Scarabaeidae and other Scarabaeoidea. Our results provide convincing support for the monophyly of Scarabaeidae, confirming the debated sister group relationship of dung beetles and phytophagous pleurostict scarabs. Supermatrix-based maximum likelihood and multispecies coalescent phylogenetic analyses strongly imply the subfamily Melolonthinae as currently understood being paraphyletic. We consequently suggest various changes in the systematics of Melolonthinae: Sericinae Kirby, 1837 stat. rest. and sensu n. to include the tribes Sericini, Ablaberini and Diphucephalini, and Sericoidinae Erichson, 1847 stat. rest. and sensu n. to include the tribes Automoliini, Heteronychini, Liparetrini, Maechidiini, Scitalini, Sericoidini, and Phyllotocini. Both subfamilies appear to consistently form a monophyletic sister group to all remaining subfamilies so far included within pleurostict scarabs except Orphninae. Our results represent a major step towards understanding the diversification history of one of the largest angiosperm-associated radiations of beetles.

Abstract

Animal genomes vary widely in size, and much of their architecture and content remains poorly understood. Even among related groups, such as orders of insects, genomes may vary in size by orders of magnitude–for reasons unknown. The largest known insect genomes were repeatedly found in Orthoptera, e.g., Podisma pedestris (1C = 16.93 pg), Stethophyma grossum (1C = 18.48 pg) and Bryodemella holdereri (1C = 18.64 pg). While all these species belong to the suborder of Caelifera, the ensiferan Deracantha onos (1C = 19.60 pg) was recently found to have the largest genome. Here, we present new genome size estimates of 50 further species of Ensifera (superfamilies Gryllidea, Tettigoniidea) and Caelifera (Acrididae, Tetrigidae) based on flow cytometric measurements. We found that Bryodemella tuberculata (Caelifera: Acrididae) has the so far largest measured genome of all insects with 1C = 21.96 pg (21.48 gBp). Species of Orthoptera with 2n = 16 and 2n = 22 chromosomes have significantly larger genomes than species with other chromosome counts. Gryllidea genomes vary between 1C = 0.95 and 2.88 pg, and Tetrigidae between 1C = 2.18 and 2.41, while the genomes of all other studied Orthoptera range in size from 1C = 1.37 to 21.96 pg. Reconstructing ancestral genome sizes based on a phylogenetic tree of mitochondrial genomic data, we found genome size values of >15.84 pg only for the nodes of Bryodemella holdereri / B. tuberculata and Chrysochraon dispar / Euthystira brachyptera. The predicted values of ancestral genome sizes are 6.19 pg for Orthoptera, 5.37 pg for Ensifera, and 7.28 pg for Caelifera. The reasons for the large genomes in Orthoptera remain largely unknown, but a duplication or polyploidization seems unlikely as chromosome numbers do not differ much. Sequence-based genomic studies may shed light on the underlying evolutionary mechanisms.

Abstract

The aim was to evaluate hospitalization rates for aneurysmal subarachnoid hemorrhage (SAH) within an interdisciplinary multicenter neurovascular network (NVN) during the shutdown for the COVID-19 pandemic along with its modifiable risk factors. In this multicenter study, admission rates for SAH were compared for the period of the shutdown for the COVID-19 pandemic in Germany (calendar weeks (cw) 12 to 16, 2020), the periods before (cw 6–11) and after the shutdown (cw 17–21 and 22–26, 2020), as well as with the corresponding cw in the years 2015–2019. Data on all-cause and pre-hospital mortality within the area of the NVN were retrieved from the Department of Health, and the responsible emergency medical services. Data on known triggers for systemic inflammation, e.g., respiratory viruses and air pollution, were analyzed. Hospitalizations for SAH decreased during the shutdown period to one-tenth within the multicenter NVN. There was a substantial decrease in acute respiratory illness rates, and of air pollution during the shutdown period. The implementation of public health measures, e.g., contact restrictions and increased personal hygiene during the shutdown, might positively influence modifiable risk factors, e.g., systemic inflammation, leading to a decrease in the incidence of SAH.

Abstract

We provide an updated catalogue of the type material of the lepidopteran superfamily Papilionoidea deposited in the Zoological Museum of Hamburg (ZMH). We report 414 specimens labelled as “types” belonging to nine species (all of valid names), 74 subspecies (44 valid names and 30 synonyms), 59 invalid infrasubspecific names under the ICZN code, and 23 specimens of 16 “in litteris” (= unavailable) names. Out of the 414 specimens labelled as “types”, 171 specimens are primary types (8 holotypes/lectotypes and 163 syntypes) and 80 are secondary types; 120 specimens are infrasubspecific and hence invalid and are considered as “original specimens”; and 43 specimens are treated here as “Non-type” specimens (topotype). We present a full bibliography of the original descriptions and illustrations for all of these taxa, aiming to provide a comprehensive taxonomic guide to this collection.

Abstract

Catoclastus Solier, 1851 (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), a genus endemic to Peru, is revised. Based on morphology and examination of type specimens, Catoclastus jaumesi Soula, 2010 is a new synonym of C. chevrolatii Solier, 1851, while Catoclastus rabinovichi Martínez, 1971 is transferred to the genus Mecopelidnota Bates, 1904, leading to Mecopelidnota rabinovichi (Martínez) as a new combination. Characters that characterize the genus, natural history, and distribution data are given. Implications and problems associated with intraspecific variability of C. chevrolatii are discussed. As a result of our research, the genus is considered monotypic and endemic to western Peru.

Abstract

This study summarizes available data on karyotypes of water scavenger beetles (Coleoptera: Hydrophiloidea: Hydrophilidae), based on newly acquired data of 23 genera and 64 species. We combine these data with previously published data, which we review. In total, karyotypes are available for 33 genera and 95 species, covering all subfamilies and tribes. Available data indicate that most groups of the Hydrophilidae are diploid and sexually reproducing, with XY (♂) and XX (♀) sex chromosomes; the Y chromosome is always minute and does not recombine with X during meiosis. Exceptions are known in Anacaena, with parthenogenetic diploid or triploid populations in some species and sex chromosomes fused with autosomes in others. The diploid number of chromosomes is 2n = 18 in the subfamilies Acidocerinae, Chaetarthriinae, Enochrinae and Hydrophilinae. Variations are known in species of Anacaena and Berosus (both usually with 2n = 18) and in Hydrochara and Hydrophilus with an increased number of chromosomes (2n = 30). The number of chromosomes is increased in the subfamily Cylominae (2n = 24–30) and in all subclades of the subfamily Sphaeridiinae (2n = 22–32). We summarize protocols for obtaining chromosome slides used for this study and provide step-by-step guidelines to facilitate future cytogenetic studies.

Abstract

The Brazilian endemic irroratus species group of the genus Inca (Scarabaeidae, Cetoniinae) is defined and described. This species group is composed of Inca irroratus Chevrolat, 1833 and two new species: I. axeli sp. nov. and I. neglectus sp. nov. One new synonym is proposed: I. irroratus Chevrolat, 1833 = I. burmeisteri Burmeister, 1844 syn. nov. To guarantee nomenclatural stability, a neotype is designated for I. irroratus and a lectotype for I. burmeisteri. A key to all species of Inca and a map with the distribution of the irroratus species group are provided.

Abstract

International audience; BACKGROUND: Patients who have had a stroke with unknown time of onset have been previously excluded from thrombolysis. We aimed to establish whether intravenous alteplase is safe and effective in such patients when salvageable tissue has been identified with imaging biomarkers. METHODS: We did a systematic review and meta-analysis of individual patient data for trials published before Sept 21, 2020. Randomised trials of intravenous alteplase versus standard of care or placebo in adults with stroke with unknown time of onset with perfusion-diffusion MRI, perfusion CT, or MRI with diffusion weighted imaging-fluid attenuated inversion recovery (DWI-FLAIR) mismatch were eligible. The primary outcome was favourable functional outcome (score of 0-1 on the modified Rankin Scale [mRS]) at 90 days indicating no disability using an unconditional mixed-effect logistic-regression model fitted to estimate the treatment effect. Secondary outcomes were mRS shift towards a better functional outcome and independent outcome (mRS 0-2) at 90 days. Safety outcomes included death, severe disability or death (mRS score 4-6), and symptomatic intracranial haemorrhage. This study is registered with PROSPERO, CRD42020166903. FINDINGS: Of 249 identified abstracts, four trials met our eligibility criteria for inclusion: WAKE-UP, EXTEND, THAWS, and ECASS-4. The four trials provided individual patient data for 843 individuals, of whom 429 (51%) were assigned to alteplase and 414 (49%) to placebo or standard care. A favourable outcome occurred in 199 (47%) of 420 patients with alteplase and in 160 (39%) of 409 patients among controls (adjusted odds ratio [OR] 1·49 [95% CI 1·10-2·03]; p=0·011), with low heterogeneity across studies (I(2)=27%). Alteplase was associated with a significant shift towards better functional outcome (adjusted common OR 1·38 [95% CI 1·05-1·80]; p=0·019), and a higher odds of independent outcome (adjusted OR 1·50 [1·06-2·12]; p=0·022). In the alteplase group, 90 (21%) patients were severely disabled or died (mRS score 4-6), compared with 102 (25%) patients in the control group (adjusted OR 0·76 [0·52-1·11]; p=0·15). 27 (6%) patients died in the alteplase group and 14 (3%) patients died among controls (adjusted OR 2·06 [1·03-4·09]; p=0·040). The prevalence of symptomatic intracranial haemorrhage was higher in the alteplase group than among controls (11 [3%] vs two [\textless1%], adjusted OR 5·58 [1·22-25·50]; p=0·024). INTERPRETATION: In patients who have had a stroke with unknown time of onset with a DWI-FLAIR or perfusion mismatch, intravenous alteplase resulted in better functional outcome at 90 days than placebo or standard care. A net benefit was observed for all functional outcomes despite an increased risk of symptomatic intracranial haemorrhage. Although there were more deaths with alteplase than placebo, there were fewer cases of severe disability or death. FUNDING: None.

Abstract

The type material of Australian Anoplognathini (Coleoptera: Scarabaeidae: Rutelinae) housed in Swedish natural history collections is reviewed, concerning three genera: Anoplognathus Leach, 1815, Amblyterus MacLeay, 1819, and Repsimus MacLeay, 1819. The species were described by G.J. Billberg, J.W. Dalman, L. Gyllenhal, C.J. Schönherr, O. Swartz, and C.P. Thunberg. The contemporary type material of W.S. MacLeay in the Macleay Museum, Sydney, is also examined as it has been overlooked by previous researchers. In total, type specimens for 12 species described between 1817 and 1822 were found in the Naturhistoriska Riksmuseet in Stockholm the Evolutionsmuseet in Uppsala and the Macleay Museum. Five of these species are valid: Anoplognathus brunnipennis, (Gyllenhal, 1817); A. olivieri (Schönherr & Dalman, 1817); A. porosus (Dalman, 1817); Amblyterus cicatricosus (Gyllenhal, 1817); and Repsimus manicatus (Swartz, 1817). The other seven species are junior synonyms, as follows (senior synonym first): A. brunnipennis = Rutela chloropyga Thunberg, 1822 (new synonym); A. olivieri = Rutela lacunosa Thunberg, 1822 (new synonym); A. viridiaeneus (Donovan, 1805) = A. latreillei (Schönherr & Gyllenhal, 1817); A. viriditarsus Leach, 1815 = Rutela analis Dalman, 1817; and R. manicatus = Anoplognathus brownii W.J. MacLeay, 1819 = A. dytiscoides W. J. MacLeay, 1819 = Rutela ruficollis Thunberg, 1822 (new synonym). Authorship of A. latreillei and A. olivieri is corrected, as noted above. Anoplognathus brunnipennis has been misidentified for the last 60 years at least, leading to the synonymy noted above. Anoplognathus flavipennis Boisduval, 1835 (revised status), is reinstated as the oldest available name for the misidentified A. brunnipennis and the types of A. flavipennis in the Muséum National d’Histoire Naturelle, Paris, are illustrated. Lectotypes are designated for: Anoplognathus brownii, A. flavipennis, A. dytiscoides, Melolontha cicatricosa, Rutela analis, R. brunnipennis, R. lacunosa, R. latreillei, R. manicata, R. olivieri, R. porosa, R. ruficollis, and R. chloropyga. Photographs of all type specimens examined are presented for the first time.

Abstract

The Asian bamboo borer Chlorophorus annularis is a beetle species that has been introduced in many countries globally. Originating in Southeast Asia, it can now be found in the Americas, South Africa, the Middle East, Australasia and Europe. The literature record of the species in Europe consists of findings of single individuals usually associated with imported bamboo products. A general European effort in surveying C. annularis was never undertaken, since the overall scientific consensus was that the species cannot establish here. Yet, recent records in Genk, Torhout (Belgium) and in Hamburg (Germany) do not seem directly associated with a recently imported product and hence may indicate otherwise. Such a shortfall in recording commonly imported, potentially invasive species may be counteracted through citizen science initiatives, allowing for continuous, high density monitoring. In this paper we present thirteen new records of the species from five European countries, including two new country records, mostly going back to interested citizen scientists.

Abstract

We present an annotated catalogue for the tribe Incini (Coleoptera: Scarabaeidae: Cetoniinae) including references to all taxonomic and nomenclatural acts, clarifying the spelling of names, providing type depositories and occurrence records for the species. The spelling of Golinca davisii (Waterhouse, 1877) is fixed, and the incorrect subsequent spelling Pantodinus klugi Burmeister, 1847 is preserved. A comprehensive list of all valid names in Incini is provided. Furthermore, we describe the third species in the genus Archedinus Morón & Krikken, 1990, and first one known from outside of Mexico, A. antoshkai Seidel & Arriaga-Varela sp. nov. from Cerro las Minas, the highest mountain in Honduras. We provide an updated determination key for the species of Archedinus. The new species is compared with Archedinus howdeni Morón & Vaz-de-Mello, 2007, the most similar species in terms of genital and habitus morphology. An updated key to identification of males of Archedinus is provided.

Abstract

Dated species-level phylogenies are crucial for understanding the origin and evolutionary history of modern faunas, yet difficult to obtain due to the frequent absence of suitable age calibrations at species level. Substitution rates of related or more inclusive clades are often used to overcome this limitation but the accuracy of this approach remains untested. We compared tree dating based on substitution rates with analyses implementing fossil data by direct node-dating and indirect root-age constraints for the New Zealand endemic Berosus water beetles (Coleoptera: Hydrophilidae). The analysis based solely on substitution rates indicated a Miocene colonization of New Zealand and Pleistocene origin of species. By contrast, all analyses that implemented fossil data resulted in significantly older age estimates, indicating an ancient early Cenozoic origin of the New Zealand clade, diversification of species during or after the Oligocene transgression and Miocene-Pliocene origin of within-species population structure. Rate-calibrated time trees were incongruent with recently published Coleoptera time trees, the fossil record of Berosus and the distribution of outgroup species. Strong variation of substitution rates among Coleoptera lineages, as well as among lineages within the family Hydrophilidae, was identified as the principal reason for low accuracy of rate-calibrated analyses, resulting in underestimated node ages in Berosus. We provide evidence that Oligocene to Pliocene events, rather than the Pleistocene Glacial cycles, played an essential role in the formation of the modern New Zealand insect fauna.

Abstract

The systematics and the phylogenetic position of the Caribbean representatives of Phaenonotum Sharp (Coleoptera: Hydrophilidae) are investigated in order to understand the composition of the Caribbean fauna and its origin. Phylogenetic analysis based on mitochondrial and nuclear genes has revealed the Caribbean species to be situated in three deeply nested clades, inferring multiple colonization of Caribbean islands from the continent. Time-tree analysis and BioGeoBEARS analyses of ancestral ranges estimated the oldest clade, consisting of wingless single-island endemics of Cuba ( P. delgadoi ), Jamaica ( P. ondreji sp. nov. ) and Hispaniola ( P. laterale sp. nov. ), to have diverged ca. 46.6 Ma from the South American ancestor and subsequently colonizing the Caribbean most likely via the GAARlandia land bridge connecting South America with Greater Antilles. The remaining three Caribbean species, including the Puerto Rican endemic, P. borinquenum sp. nov. , are of more recent (Miocene to Pliocene) origin and colonized the Greater Antilles by over-water dispersal. All the Caribbean species are illustrated and diagnosed and three new species are described. The genus Phaenonotum , excluding P. caribense Archangelsky, is confirmed as a monophylum. We demonstrate that species-level taxonomy of Phaenonotum is difficult to solve by morphology alone, and ideally requires the combination of morphology and molecular markers.

Abstract

Gastrointestinal (GI) involvement is almost universal in patients with systemic sclerosis (SSc) and is associated with significant disease-related morbidity and mortality.1 The entire GI tract can be involved and other disease features (eg, low mood, terminal organ failure and functional hand impairment) can result in significant nutritional impairment. Severe GI involvement has been reported to occur in ~10% of patients with SSc and often occurs early in the course of the disease.2 However, identification of patients at high risk of clinically significant weight loss is extremely challenging, including from the high prevalence of GI symptoms in patients with SSc. Therefore, there is a need to understand high-risk patients including potentially modifiable risk factors, with a view to early intervention strategies. Against this background, the aim of this study was to examine potential clinical risk factors of significant weight loss in patients with SSc. We performed an analysis of patients with SSc enrolled in the multinational, longitudinal European League Against Rheumatism (EULAR) Scleroderma Trials and Research (EUSTAR) database. In our study, we defined significant weight loss as 4.5 kg and/or least 5% of their body weight at 5 months onwards.3 Patients with a recorded second visit after 3 months and before 12 months were included in the analysis. We adopted a pragmatic approach (relevant to clinical practice) in …

Abstract

The New Zealand endemic beetle genus Saphydrus Sharp, 1884 (Coleoptera:Hydrophilidae:Cylominae) is studied in order to understand its phylogenetic position, species-level systematics, biology and distribution, and to reveal reasons for its rarity. The first complete genus-level phylogeny of Cylominae based on two mitochondrial (cox1, 16S) and two nuclear genes (18S, 28S) covering 18 of 19 genera of the subfamily reveals Saphydrus as an isolated lineage situated in a clade with Cylorygmus (South America), Relictorygmus (South Africa) and Eurygmus (Australia). DNA is used to associate two larval morphotypes with Saphydrus: one of them represents the larvae of S. suffusus Sharp, 1884; the other, characterised by unique characters of the head and prothorax morphology, is revealed as sister but not closely related to Saphydrus. It is described here as Enigmahydrus, gen. nov. with a single species, E. larvalis, sp. nov., whose adult stage remains unknown. Saphydrus includes five species, two of which (S. moeldnerae, sp. nov. and S. tanemahuta, sp. nov.) are described as new. Larvae of Enigmahydrus larvalis and Saphydrus suffusus are described and illustrated in detail based on DNA-identified specimens. Candidate larvae for Saphydrus obesus Sharp, 1884 and S. tanemahuta are illustrated and diagnosed. Specimen data are used to evaluate the range, altitudinal distribution, seasonality and population dynamics over time for all species. Strongly seasonal occurrence of adults combined with other factors (winter occurrence in S. obesus, occurrence at high altitudes in S. tanemahuta) is hypothesised as the primary reason of the rarity for Saphydrus species. By contrast, Enigmahydrus larvalis underwent a strong decline in population number and size since the 1970s and is currently known from a single, locally limited population; we propose the ‘nationally threatened’ status for this species. http://zoobank.org/urn:lsid:zoobank.org:pub:28D87163-29E8-418C-9380-262D3038023A

Abstract

Background Increased nerve growth factor (NGF) levels are associated with chronic pain conditions, including low back pain and osteoarthritis (OA). NGF signalling through its receptor TrkA regulates pro-inflammatory neurotransmitters such as substance P (SP). Inhibition of NGF has shown therapeutic efficacy in knee OA [1] and chronic back pain [2], but trials have revealed rare cases of rapidly progressive OA of peripheral joints. Objectives To describe the tissue distribution of NGF, TrkA, SP and macrophages in facet joint osteoarthritis (FJOA) of the lumbar spine and their association with FJOA grade. Methods FJOA specimens were obtained by facetectomy from patients undergoing intervertebral fusion (n=10, average age 69 years, 5 males). FJOA severity and presence of synovial hypertrophy was graded using preoperative magnetic resonance imaging (MRI). Relative abundance of NGF, CD68 (macrophages), TrkA and SP in capsular synovium (SY), cartilage (CL), subchondral bone (SB) and subchondral bone marrow (BM) was evaluated semi-quantitatively on a scale ranging from 0-3 using immunohistochemistry. Association between imaging parameters and tissue expression was determined using Pearson correlation analysis. Results Synovial hypertrophy as determined by MRI was present in six cases (60%) and median Weishaupt grade of FJOA was 2 (1.5-3) corresponding with moderate to severe OA. NGF was abundantly expressed in SY (3 [0.5-3]) and to a lesser extent in BM tissues (2 [1-3]), whereas TrkA expression was detected in BM exclusively. NGF abundance in SY and BM showed a strong correlation (r=0.94), but did not associate with synovial hypertrophy or FJOA severity. CD68+ macrophages were highly abundant in BM (3 [1.5-3]) and sparse in SY tissues (0.5 [0-1]). The relative abundance of macrophages and NGF was strongly correlated in SY tissue only (r = 0.78). SP as a downstream mediator of NGF signalling was also abundantly expressed in SY, CL and BM tissues. Tissue distributions of CD68, NGF and SP are summarized in the figure. Conclusion NGF expression and signalling is evident in lumbar spine FJOA specimens, but not strongly associated with synovial hypertrophy or disease severity. These results are in agreement with recent studies of human knee OA, which have shown osteochondral NGF expression as a hallmark of symptomatic OA independently of chondropathy or synovitis [3].

Abstract

Background CRP and/or ESR are often unreliable indicators of disease activity. Serum markers of endothelial activation may be promising alternatives. We have recently shown that soluble vascular cell adhesion molecule-1 (sVCAM-1) is elevated in patients with positive antinuclear antibodies [1]. We also have described similar findings in another cohort of patients with a variety of rheumatic diseases [2] and now report a multivariate analysis of these data. Objectives CRP, ESR, age, disease and gender were correlated to sVCAM-1. Methods Cross-sectional study with 230 patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA) and different vasculitides (VASC). Disease activities were determined using DAS28, BASDAI, BVAS, RF, ACPA, CRP or ESR. Treatment regimens were subgrouped for conventional DMARDs (cDMARDs) or sets of biologics (bDMARDs). sVCAM-1 (ng/ml) was determined in the serum by ELISA and data were compared to age- and gender-matched healthy controls (HC). Results Significant (p 0.05) overexpression of sVCAM-1 as compared to HC were found in the following groups and subgroups (subgroup data not shown): RA (n=136): 1.26-fold and in subgroups with bDMARDs, female gender, age >50 years, and RF≥15 IU/ml. AS (n=34): 1.71-fold and in subgroups with bDMARDs, age ≤50 years, female gender, CRP 10, disease duration ≤120 months, age ≤50 years, female and male gender, CRP ≤3 mg/dl, and ESR ≤20 mm/h. PsA (n=35): no significant changes. Linear regression analysis showed that CRP and ESR but not sVCAM-1 were correlated to each other (r=0.637, p Conclusion sVCAM-1 is an objective disease marker in patients with RA, AS and VASC. sVCAM-1 is not correlated with CRP and ESR and may thus provide additional information of disease activity. Prospective studies are needed to establish sVCAM-1 as a marker of rheumatic diseases, especially in vasculitis. References [1] Oleszowsky M, Seidel MF.

Abstract

Two aberrant ground beetle (Coleoptera: Carabidae) specimens from the genusCalosomaWeber, 1801 were collected in Waco, Texas, United States of America, in 2012–2013. The specimens, which are morphologically most similar toCalosoma wilcoxiLeConte, 1848, but are dark blue-black instead of the typical metallic green. We employed DNA barcoding and phylogenetic methods to confirm the identities of the aberrant specimens. Preliminary phylogenetic analyses of cytochrome oxidase subunit 1 (COI) sequences of central Texas and southwestern species place the aberrant specimens with 100% confidence asC. wilcoxi.The new variant ofC. wilcoxipresumably occurs at low densities. Frequent collecting from 2011 to 2014 resulted in the discovery of only two of the aberrant coloured individuals among hundreds of typical green specimens. These specimens (to our knowledge) represent the first published record of melanisticCalosomafrom North America. While the majority of North American species in the genus are naturally black, two of the most widely distributed and abundant species,C. scrutator(Fabricius, 1775) andC. wilcoxi, are typically green. We sequenced the aberrant form as well as all species co-occurring with the new colour morph at the collection locality and used records from GenBank and the Barcode of Life Data System to generate a preliminary phylogeny of the genus, which suggested that some of the currently established subgenera are likely not monophyletic.
