Volkmar Siguschs 1984 erschienenes Buch "Die Mystifikation des Sexuellen" bietet gute Anknüpfungspunkte, um die Eingebundenheit der Kategorien "Geschlecht" und "Sexualität" in die kapitalistische Produktionsweise verstehen und Ableitungen für emanzipatorisches Streiten treffen zu können. Zusammen mit weiteren – auch neueren – Arbeiten Siguschs ergeben sich Anschlussmöglichkeiten für die kapitalismuskritische und antikapitalistische Fortentwicklung feministischer und queer-feministischer Ansätze.
Since the study of Late Antiquity evolved in the last few decades into an important research topic, several publications have been dedicated to the late antique city, resulting in lively discussions on "decline" and "transition". In line with this evolution Late Antiquity has recently been the central theme of several conferences and workshops, dealing with specific study themes of Late Antiquity as a whole, focussing on a particular time period and/or dedicated to well-defined geographical areas. ...
After this contribution dealing with the capital of Asia, the paper of Axel Filges discusses the late antique and Byzantine situation in the smaller town of Blaundos in Phrygia (Zum Aussagepotential ruinöser Mauern. Bevölkerung und Bebauung im spätantiken und byzantinischen Blaundos [Phrygia]). ...
I characterize optimal monetary and fiscal policy in a stochastic New Keynesian model when nominal interest rates may occasionally hit the zero lower bound. The benevolent policymaker controls the short-term nominal interest rate and the level of government spending. Under discretionary policy, accounting for fiscal stabilization policy eliminates to a large extent the welfare losses associated with the presence of the zero bound. Under commitment, the gains associated with the use of the fiscal policy tool remain modest, even though fiscal stabilization policy is part of the optimal policy mix.
The taxonomic position of Onthophagus (Palaeonthophagus) lemuroides d’Orbigny, 1898 and Onthophagus
(Palaeonthophagus) fortigibber Reitter, 1909 is discussed (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini).
A key to the species is given. Photos of type specimens of the two taxa and significant chromatic varieties, and
drawings of aedeagi are presented.
Missachtung rechtlicher Vorgaben des AEUV durch die Mitgliedstaaten und die EZB in der Schuldenkrise
(2012)
Zusammenfassung und Ergebnisse
1. Es gibt gute Argumente für ein generelles Verbot (freiwilliger) Unterstützungsleistungen an Euro-Mitgliedstaaten.
2. Die Vereinbarkeit der Leistungen der EU im Rahmen des EFSM mit Art. 122 Abs. 2 AEUV ist fraglich. Die Beurteilung der Kausalitätsfrage ist maßgebend.
3. Die Vereinbarkeit der Leistungen der Mitgliedstaaten im Rahmen der speziellen Griechenlandhilfe und im Rahmen der EFSF mit dem AEUV in der damals geltenden Fassung ist nicht sicher.
4. Die Einführung von Art. 136 Abs. 3 AEUV modifiziert das Vertragsrecht und ist wohl noch in Einklang mit Art. 48 Abs. 6 EUV erfolgt.
5. ESM und Fiskalpakt verstoßen nach der Änderung des Primärrechts wohl nicht gegen den AEUV.
6. Unabdingbar für die Schaffung des ESM sind aber das Inkrafttreten von Art. 136 Abs. 3 AEUV und
7. Der Erwerb von Forderungen gegen Mitgliedstaaten über einen längeren Zeitraum und zur Erleichterung von Zinslasten überschreitet die Befugnisse und Zuständigkeiten des ESZB.
8. Der Erwerb von Forderungen gegen Mitgliedstaaten über einen längeren Zeitraum und zur Erleichterung von Zinslasten ist nicht mit dem Verbot der Kreditgewährung durch Zentralbanken an Hoheitsträger nach Art. 123 AEUV zu vereinbaren
9. Die Gewährung von langfristigen Krediten an Banken verstößt ebenfalls gegen die Zuständigkeitsordnung des AEUV und ist bei einer Weiterleitung der Mittel an Hoheitsträger nicht mit Art. 123 AEUV zu vereinbaren.
10. Die Akzeptierung von ausfallgefährdeten Forderungen als Sicherheit für die Gewährung von Krediten durch das ESZB verstößt gegen Art. 18.1., zweiter Spiegelstrich, Satzung ESZB/EZB.
We use a novel disaggregate sectoral euro area data set with a regional breakdown to investigate price changes and suggest a new method to extract factors from over-lapping data blocks. This allows us to separately estimate aggregate, sectoral, country-specific and regional components of price changes. We thereby provide an improved estimate of the sectoral factor in comparison with previous literature, which decomposes price changes into an aggregate and idiosyncratic component only, and interprets the latter as sectoral. We find that the sectoral component explains much less of the variation in sectoral regional inflation rates and exhibits much less volatility than previous findings for the US indicate. We further contribute to the literature on price setting by providing evidence that country- and region-specific factors play an important role in addition to the sector-specific factors, emphasising heterogeneity of inflation dynamics along different dimensions. We also conclude that sectoral price changes have a “geographical” dimension, that leads to new insights regarding the properties of sectoral price changes.
Extreme economic effects globally of various populations of the whitefly Bemisia tabaci (Gennadius)
(Hemiptera: Aleyrodidae) led to an in depth study of the morphology of that species as well as that of
numerous other species of whiteflies in the genus Bemisia Quaintance and Baker and other similar appearing
species. The data collected are presented here as illustrations of the puparia (fourth instar nymphal stages)
and discussions of morphology as it relates to species and generic separations within this closely knit group
of insects. A brief history of the pest outbreaks of B. tabaci is given and an overview of the important
morphological characteristics of aleyrodine whiteflies is provided. Each of the eighty illustrations is
accompanied by a discussion of the more important aspects of morphology.
A taxonomic review of the ancora species group of Graphipterus Latreille (Coleoptera: Carabidae)
(2012)
The taxonomy of the ancora species group of Graphipterus Latreille (Coleoptera: Carabidae) is reviewed and seven species are recognized, all from southern Africa: Graphipterus ancora Dejean, Graphipterus cordiger Dejean, Graphipterus distinctus Péringuey (new status), Graphipterus fasciatus Chaudoir, Graphipterus fritschi Chaudoir, Graphipterus wahlbergi Boheman (new status), and Graphipterus westwoodi Brême (new status).
Diagnostic features are provided for each species and adult specimens of each species are illustrated.
Two new species of the genus Pahamunaya Schmid (Trichoptera: Polycentropodidae), P. talon sp. n. and P. spinifera sp. n., from Vietnam are described and illustrated. Examination of the holotype male of P. khoii Oláh and Johanson, in combination with an additional specimen of the same species, revealed new characters. New illustrations for this species are provided.
Significant new host and distribution records are presented for Hylesinus mexicanus (Wood) (Coleoptera: Curculionidae: Scolytinae), including its pest potential on cultivated olives. Hylesinus mexicanus is similar to H. fasciatus LeConte and information presented here suggests that the distinctiveness of these two species needs to be re-examined.
Currently, the genus Chimarra Stephens (Trichoptera: Philopotamidae) is represented in the Oriental Region by 259 species. Of these, 61 species have been described or recorded from Vietnam. In this paper, 9 new species from Vietnam are described and illustrated (Chimarra aculeata, C. carinata, C. corneola, C. insolita, C. mina, C. prominens, C. rostrata, C. undulata, and C. ungula). In addition, 3 new country records are noted (Chimarra areli Malicky and Mey, Chimarra pipake Malicky and Chantaramongkol, and Chimarra suthepensis Chantaramongkol and Malicky), and 1 new species group (minuta Group) is proposed and populated. An additional species group (georgensis “Group”), with 1 new species from Vietnam, but otherwise only known from Africa, is discussed, but not formally defined. A table listing all known Vietnamese species of Chimarra is included, along with discussion of variability in the anal veins of the forewing found within this genus, and its relevance for defining subgenera and species groups.

“Far, far away from our areas, somewhere beyond the Mountains of Darkness, on the other side of the Sambatyon River…there lives a nation known as the Red Jews.” The Red Jews are best known from classic Yiddish writing, most notably from Mendele's Kitser masoes Binyomin hashlishi (The Brief Travels of Benjamin the Third). This novel, first published in 1878, represents the initial appearance of the Red Jews in modern Yiddish literature. This comical travelogue describes the adventures of Benjamin, who sets off in search of the legendary Red Jews. But who are these Red Jews or, in Yiddish, di royte yidelekh? The term denotes the Ten Lost Tribes of Israel, the ten tribes that in biblical times had composed the Northern Kingdom of Israel until they were exiled by the Assyrians in the eighth century BCE. Over time, the myth of their return emerged, and they were said to live in an uncharted location beyond the mysterious Sambatyon River, where they would remain until the Messiah's arrival at the end of time, when they would rejoin the rest of the Jewish people.
This article is part of a broader study of the Red Jews in Jewish popular culture from the Middle Ages through modernity. It is partially based on a chapter from my book, Umstrittene Erlöser: Politik, Ideologie und jüdisch-christlicher Messianismus in Deutschland, 1500–1600 (Göttingen: Vandenhoeck & Ruprecht, 2011). Several postdoctoral fellowships have generously supported my research on the Red Jews: a Dr. Meyer-Struckmann-Fellowship of the German Academic Foundation, a Harry Starr Fellowship in Judaica/Alan M. Stroock Fellowship for Advanced Research in Judaica at Harvard University, a research fellowship from the Heinrich Hertz-Foundation, and a YIVO Dina Abramowicz Emerging Scholar Fellowship. I thank the organizers of and participants in the colloquia and conferences where I have presented this material in various forms as well as the editors and anonymous reviewers of AJS Review for their valuable comments and suggestions. I am especially grateful to Jeremy Dauber and Elisheva Carlebach of the Institute for Israel and Jewish Studies at Columbia University, where I was a Visiting Scholar in the fall of 2009, for their generous encouragement to write this article. Sue Oren considerably improved my English. The style employed for Romanization of Yiddish follows YIVO's transliteration standards. Unless otherwise noted, translations from the Yiddish, Hebrew, German, and Latin are my own. Quotations from the Bible follow the JPS translation, and those from the Babylonian Talmud are according to the Hebrew-English edition of the Soncino Talmud by Isidore Epstein.
Der Aufsatz spricht sich für eine intensivere Auseinandersetzung der germanistischen Mediävistik mit den Postkolonialen Studien aus. Diese haben seit den 1970er Jahren im englischsprachigen Raum eine wirkmächtige Diskussionskultur ausgebildet, die seit der Jahrtausendwende auch auf die Mediävistik übergreift, im deutschsprachigen Raum aber bisher kaum rezipiert wird. Um zu zeigen, dass eine Postkoloniale Mediävistik möglich und sinnvoll ist, wird die Frage diskutiert, ob es einen mittelalterlichen Kolonialismus gibt und es wird erörtert, worauf sich das ›Post‹ in ›postkolonial‹ bezieht. Ein kurzer Blick auf die angloamerikanische Forschung zeigt, welche Wege bereits beschritten wurden. Schließlich werden anhand von fünf hochmittelalterlichen Texten (Gesta Francorum, Willehalm, Rolandslied, Parzival, Herzog Ernst) exemplarische postkoloniale Lektüren vorgestellt. Solche Postkolonialen Lektüren sind, so die grundlegende Annahme, keine kulturwissenschaftliche Spielerei, sondern ein Verfahren zur Auseinandersetzung mit elementaren kulturellen und narrativen Konstellationen.
Im Folgenden wird […] [z]unächst […] an Daniel Cramers Emblemata sacra die dem Emblem eignende sakramentale Prägekraft als Einprägung des Wortes Gottes in die Seele des Rezipienten erläutert. Dieses der Emblematik zugesprochene Vermögen thematisiert Cramer nicht nur in einem metareflexiven Emblem, er legt es seinem Emblembuch auch konzeptionell als ein Element des Heilsweges zu göttlicher Gnade zugrunde. Diese meditative Funktion der Emblematik wird vor allem durch den Status des Wortes als göttliches Wort gewährleistet, das durch die Pictura, das äußere Bild, der Seele des Gläubigen, gleichsam als inneres Bild (imago), eingeprägt werden kann. Insbesondere in den Schriften der Sprachtheoretiker Justus Georg Schottelius und Georg Philipp Harsdörffer lassen sich Zusammenhänge zwischen den göttlichen Zeichen der Hieroglyphik als Grundlage der Emblematik und einer ontologischen Zeichentheorie festmachen, die sich auf die unmittelbare Verbindung von Sache und Wort vor der Folie der lingua adamica beruft. Beide Konzepte, die Präsenzwerdung des absenten göttlichen Predigtwortes durch die Prägekraft der Pictura in Cramers heiligen Emblemen sowie der sprachpatriotische Status des göttlichen Wortes, finden eine messtheologische Synthese in Johann Michael Dilherrs Predigtsammlung der Heiligen Sonn- und Festtags-Arbeit. Abschließend wird hier der emblematische Vollzug des Sakramentalen exemplarisch zu rekonstruieren sein.
MoSyD-Jahresbericht 2011 : Drogentrends in Frankfurt am Main : Monitoring-System Drogentrends
(2012)
How do changes in market structure affect the US business cycle? We estimate a monetary DSGE model with endogenous
rm/product entry and a translog expenditure function by Bayesian methods. The dynamics of net business formation allow us to identify the 'competition effect', by which desired price markups and inflation decrease when entry rises. We
find that a 1 percent increase in the number of competitors lowers desired markups by 0.18 percent. Most of the cyclical variability in inflation is driven by markup fluctuations due to sticky prices or exogenous shocks rather than endogenous changes in desired markups.
This paper characterises optimal monetary policy in an economy with endogenous
firm entry, a cash-in-advance constraint and preset wages. Firms must make pro
fits to cover entry costs; thus the markup on goods prices is efficient. However, because leisure is not priced at a markup, the consumption-leisure tradeoff is distorted. Consequently, the real wage, hours and production are suboptimally low. Due to the labour requirement in entry, insufficient labour supply also implies that entry is too low. The paper shows that in the absence of
fiscal instruments such as labour income subsidies, the optimal monetary policy under sticky wages achieves higher welfare than under flexible wages. The policy maker uses the money supply instrument to raise the real wage - the cost of leisure - above its flexible-wage level, in response to expansionary shocks to productivity and entry costs. This raises labour supply, expanding production and
rm entry.
Introduction: Acute kidney injury (AKI) after cardiac surgery increases length of hospital stay and in-hospital mortality. A significant number of patients undergoing cardiac surgical procedures require perioperative intra-aortic balloon pump (IABP) support. Use of an IABP has been linked to an increased incidence of perioperative renal dysfunction and death. This might be due to dislodgement of atherosclerotic material in the descending thoracic aorta (DTA). Therefore, we retrospectively studied the correlation between DTA atheroma, AKI and in-hospital mortality.
Methods: A total of 454 patients were retrospectively matched to one of four groups: -IABP/-DTA atheroma, +IABP/-DTA atheroma, -IABP/+DTA atheroma, +IABP/+DTA atheroma. Patients were then matched according to presence/absence of DTA atheroma, presence/absence of IABP, performed surgical procedure, age, gender and left ventricular ejection fraction (LVEF). DTA atheroma was assessed through standard transesophageal echocardiography (TEE) imaging studies of the descending thoracic aorta.
Results: Basic patient characteristics, except for age and gender, did not differ between groups. Perioperative AKI in patients with -DTA atheroma/+IABP was 5.1% versus 1.7% in patients with -DTA atheroma/-IABP. In patients with +DTA atheroma/+IABP the incidence of AKI was 12.6% versus 5.1% in patients with +DTA atheroma/-IABP. In-hospital mortality in patients with +DTA atheroma/-IABP was 3.4% versus 8.4% with +DTA atheroma/+IABP. In patients with +DTA atheroma/+IABP in hospital mortality was 20.2% versus 6.4% with +DTA atheroma/-IABP. Multivariate logistic regression identified DTA atheroma > 1 mm (P = *0.002, odds ratio (OR) = 4.13, confidence interval (CI) = 1.66 to 10.30), as well as IABP support (P = *0.015, OR = 3.04, CI = 1.24 to 7.45) as independent predictors of perioperative AKI and increased in-hospital mortality. DTA atheroma in conjunction with IABP significantly increased the risk of developing acute kidney injury (P = 0.0016) and in-hospital mortality (P = 0.0001) when compared to control subjects without IABP and without DTA atheroma.
Conclusions: Perioperative IABP and DTA atheroma are independent predictors of perioperative AKI and in-hospital mortality. Whether adding an IABP in patients with severe DTA calcification increases their risk of developing AKI and mortality postoperatively cannot be clearly answered in this study. Nevertheless, when IABP and DTA are combined, patients are more likely to develop AKI and to die postoperatively in comparison to patients without IABP and DTA atheroma.
This chapter aims to provide a hands-on approach to New Keynesian models and their uses for macroeconomic policy analysis. It starts by reviewing the origins of the New Keynesian approach, the key model ingredients and representative models. Building blocks of current-generation dynamic stochastic general equilibrium (DSGE) models are discussed in detail. These models address the famous Lucas critique by deriving behavioral equations systematically from the optimizing and forward-looking decision-making of households and firms subject to well-defined constraints. State-of-the-art methods for solving and estimating such models are reviewed and presented in examples. The chapter goes beyond the mere presentation of the most popular benchmark model by providing a framework for model comparison along with a database that includes a wide variety of macroeconomic models. Thus, it offers a convenient approach for comparing new models to available benchmarks and for investigating whether particular policy recommendations are robust to model uncertainty. Such robustness analysis is illustrated by evaluating the performance of simple monetary policy rules across a range of recently-estimated models including some with financial market imperfections and by reviewing recent comparative findings regarding the magnitude of government spending multipliers. The chapter concludes with a discussion of important objectives for on-going and future research using the New Keynesian framework.
This paper investigates the accuracy of point and density forecasts of four DSGE models for inflation, output growth and the federal funds rate. Model parameters are estimated and forecasts are derived successively from historical U.S. data vintages synchronized with the Fed’s Greenbook projections. Point forecasts of some models are of similar accuracy as the forecasts of nonstructural large dataset methods. Despite their common underlying New Keynesian modeling philosophy, forecasts of different DSGE models turn out to be quite distinct. Weighted forecasts are more precise than forecasts from individual models. The accuracy of a simple average of DSGE model forecasts is comparable to Greenbook projections for medium term horizons. Comparing density forecasts of DSGE models with the actual distribution of observations shows that the models overestimate uncertainty around point forecasts.
This paper investigates the accuracy of forecasts from four DSGE models for inflation, output growth and the federal funds rate using a real-time dataset synchronized with the Fed’s Greenbook projections. Conditioning the model forecasts on the Greenbook nowcasts leads to forecasts that are as accurate as the Greenbook projections for output growth and the federal funds rate. Only for inflation the model forecasts are dominated by the Greenbook projections. A comparison with forecasts from Bayesian VARs shows that the economic structure of the DSGE models which is useful for the interpretation of forecasts does not lower the accuracy of forecasts. Combining forecasts of several DSGE models increases precision in comparison to individual model forecasts. Comparing density forecasts with the actual distribution of observations shows that DSGE models overestimate uncertainty around point forecasts.
Nach den Kolloquien, die 2009 und 2010 in Braga/Portugal stattfanden, organisierte der Portugiesische Germanistikverband (APEG - Associação Portuguesa de Estudos Germanísticos) am 28. und 29. Oktober 2011 sein III. Forum, welches jungen GermanistInnen gewidmet war. Die Tagung fand in diesem Jahr an der Universität Coimbra statt und versammelte über 20 junge GermanistInnen, die ihre Forschungsarbeiten zum Thema „Em Trânsito – Übergänge. Grenzen überschreiten in der Germanistik“ vortrugen. Diese Sondernummer der REAL stellt einige der Beiträge dieses Kolloquiums der breiteren Gemeinschaft der GermanistInnen vor. Damit wollen sowohl die APEG als auch die REAL ihren Beitrag zur Förderung des internationalen Nachwuchses in der Germanistik leisten.
Die jungen GermanistInnen wurden dazu eingeladen, über Kultur als einen dynamischen Prozess und als Zusammentreffen verschiedenartiger komplexer Beziehungen von und in unterschiedlichen (Grenz)gebieten, die sich ständig neu definieren, zu äußern. Das Kolloquium gab die Möglichkeit zu einer breiten Diskussion über die Wahrnehmung von Grenzen und deren unterschiedliche Herausbildung, über Verschränkungen, Verhandlungen und Übersetzung, über Identitäten, Beziehungen und Konzepte, die sich entlang, gegen und mit diesen Grenzen herausbilden und artikulieren.
Die verschiedenen Sektionen und Beiträge dieser Sondernummer dokumentieren, dass die hybriden Gebiete und fließenden Schnittstellen, die sich beim Zusammentreffen von Grenzen ergeben, zumeist die größten Herausforderungen, aber auch die produktivsten Schauplätze für konzeptionelle Entwicklungen und praktische Analysen darstellen. Sie zwingen uns, sowohl Konzepte und Fachgebiete, als auch den eigenen Standort in der Wissenschaft zu hinterfragen, da sie den epistemologischen Prozess durch Instabilität, Bewegung und Verschiebungen beeinflussen.

In the aftermath of the global financial crisis and great recession, many countries face substantial deficits and growing debts. In the United States, federal government outlays as a ratio to GDP rose substantially from about 19.5 percent before the crisis to over 24 percent after the crisis. In this paper we consider a fiscal consolidation strategy that brings the budget to balance by gradually reducing this spending ratio over time to the level that prevailed prior to the crisis. A crucial issue is the impact of such a consolidation strategy on the economy. We use structural macroeconomic models to estimate this impact focussing primarily on a dynamic stochastic general equilibrium model with price and wage rigidities and adjustment costs. We separate out the impact of reductions in government purchases and transfers, and we allow for a reduction in both distortionary taxes and government debt relative to the baseline of no consolidation. According to the model simulations GDP rises in the short run upon announcement and implementation of this fiscal consolidation strategy and remains higher than the baseline in the long run. We explore the role of the mix of expenditure cuts and tax reductions as well as gradualism in achieving this policy outcome. Finally, we conduct sensitivity studies regarding the type of model used and its parameterization.
Abschließend stellt Solvejg Nitzke in ihrem Aufsatz 'Apokalypse von innen' dar, wie traditionelle Narrative vom Ende der Menschheit in Debatten um das Verhältnis von Mensch und Natur aktualisiert und verschärft werden. Natur wird in diesen Narrativen (wieder) zum Subjekt, das sich gegen die sie bedrohende Menschheit zur Wehr setzt. Diese Umkehrung des (Natur-)Katastrophenbegriffs zurück zu einer intentional agierenden Kraft als ihrer Ursache, stellt die Frage wer die Macht besitzt zu entscheiden, wann und vor allem für wen Gefahr und Zerstörung zur Katastrophe werden.

Wer Karla Kliches alltägliches Wirken als Redakteurin der Weimarer Beiträge längere Zeit beobachten konnte, den hat vor allem eine Haltung beeindruckt: diese Achtsamkeit gegenüber dem anderen, dieses Ernstnehmen von Autoren auch im kritischen Umgang mit ihnen, die Bewertung wissenschaftlicher Prosa nicht nur nach dispositionellen, sondern auch nach stilistischen Qualitäten, diese Wertschätzung neuer Gedanken - man muss es über Jahre hin erlebt haben, um all dies als etwas Seltenes und Kostbares zu schätzen zu wissen. Karla Kliches Umgangstugenden haben den Geist dieser Zeitschrift mitgeprägt
Quarkonia are very promising probes to study the quark-gluon plasma. The essential baseline for measurements in heavy-ion collisions is high-precision data from proton-proton interactions. However, the basic mechanisms of quarkonium hadroproduction are still being debated. The most common models, the Color-Singlet Model, the non-relativistic QCD approach and the Color-Evaporation Model, are able to describe most of the available cross-section data, despite of their conceptual differences. New measures, such as the polarization, and data at a new energy regime are crucial to test the competing models. Another issue is an eventual interplay between the production process of a quarkonium state and the surrounding pp event. Current Monte Carlo event generators treat the hard scattering independently from the rest of the so-called underlying event. The investigation of possible correlations with the pp event might be very valuable for a detailed understanding of the production processes. ALICE ist the dedicated heavy-ion experiment at the LHC. Its design has been optimized for high-precision measurements in very high track densities and down to low transverse momenta. ALICE is composed of various different detectors at forward and at central rapidities. The most important detectors for this study are the Inner Tracking System and the Time Projection Chamber, allowing to reconstruct and identify electron candidate tracks within eta < 0.9. The Transition Radiation Detector has not been utilized at this stage of the analysis; however, it will strongly improve the particle identification and provide a dedicated trigger in the upcoming beam periods. ...
The diplopod orders Callipodida and Polydesmida, and their respective families Abacionidae and
Xystodesmidae, are initially recorded from South Dakota as is Polydesmidae from North Dakota. Other new records of
indigenous taxa include Abacion Rafinesque, 1820/A. texense (Loomis, 1937) and Pleuroloma/P. flavipes, both by
Rafinesque, 1820, from South Dakota, and Pseudopolydesmus Attems, 1898/P. serratus (Say, 1821) from Alabama,
Connecticut, Delaware, New Hampshire, North Dakota, South Carolina, and the District of Columbia. New records of
Aniulus garius Chamberlin, 1912, A. (Hakiulus) d. diversifrons (Wood, 1867), and Oriulus venustus (Wood, 1864)
(Julida: Parajulidae) are provided for western Minnesota and/or eastern North Dakota. Published records from these
states are summarized, and the introduced taxa, Julidae/Cylindroiulus Verhoeff, 1894/C. caeruleocinctus (Wood, 1864)
and Paradoxosomatidae/Oxidus Cook, 1911/O. gracilis (C. L. Koch, 1847), are newly recorded from the Dakotas. The
distribution of P. serratus, which extends from Maine to South Carolina and the Florida panhandle, west to Texas, and
north to Fargo, North Dakota is described and discussed. This distribution exhibits a prominent southeastern lacuna
which we hypothesize suggests replacement by younger, more successful species, as postulated for a similar distributional
gap in Scytonotus granulatus (Say, 1821).
The chilopod, Cryptops hortensis (Donovan, 1810) (Scolopendromorpha: Cryptopidae), and the diplopods, Pseudospirobolellus avernus (Butler, 1876) (Spirobolida: Pseudospirobolellidae) and Oxidus gracilis (C. L. Koch, 1847) (Polydesmida: Paradoxosomatidae), are newly recorded from Saba Island, Lesser Antilles, which also harbors one additional scolopendromorph and four more chilognath millipeds. Except for the plausibly native scolopendrid centipede, Scolopendra alternans Leach, 1813, all are human introductions. Concentrated sampling is needed in the cloud/elfin forest atop Mt. Scenery, where indigenous millipeds may reside, and with extraction techniques throughout the island, to potentially document the diplopod subclass Penicillata. Nine small Caribbean islands in addition to Saba have been incorrectly reported as lacking diplopod records because publications citing them were overlooked by past authors. Works documenting myriapods from small Caribbean islands are consolidated.
Based on two “uni-ocellate” females, the world’s first introductions of the milliped order Stemmiulida are recorded from Florida, United States (US). One individual was collected in 1976 in Gainesville, Alachua County (Co.)., in northcentral peninsular Florida, and the other was taken in 1991 some 408 km (255 mi) to the south-southeast in Pompano Beach, Broward Co. The absence of further individuals and additional samples suggests that the introductions did not result in viable populations, and stemmiulidans are not presently established in the state; the Gainesville site was reinvestigated in 2012 without finding additional specimens. New records from Mexico include the first from Chiapas, Oaxaca, Tabasco, Yucatan, San Luis Potosí, and Tamaulipas states, with the northernmost ordinal locality now becoming Rancho del Cielo, northwest of Gómez Farias, in the last. A northward range expansion of about 460 km (288 mi) from the previous limit, Xalapa, Veracruz, the site lies a mere 40 km (25 mi) south of the Tropic of Cancer and only some 320 km (200 mi) south of the Rio Grande and the US border at McAllen, Hidalgo Co., Texas. Indigenous Stemmiulida are not expected in the forested Rio Grande Valley of southernmost Texas, but their occurrence in the adjoining Mexican state renders such a discovery more plausible than before.
The milliped genus Euryurus Koch, 1847, and the species, E. leachii (Gray, 1832) (Polydesmida: Euryuridae), are recorded from three sites on the northern part of Crowley’s Ridge (Cross, Lee, and Poinsett counties), Arkansas, where the only prior familial records are of Auturus evides (Bollman, 1887). Coupled with the published locality of E. leachii in Phillips Co., at the southern extremity of the Ridge, the only known occurrences of both the genus and species in Arkansas and west of the Mississippi River are in this physiographic feature. The Arkansas population is geographically peripheral but anatomically intermediate between the two recognized subspecies, E. l. leachii and E. l. fraternus Hoffman, 1978, and we do not assign it to a race. Molecular investigations seem necessary to resolve relationships in the “E. leachii complex.”
