Abstract Since the 1970s Ordovician carbonate rocks from Kazakhstan have provided well-preserved radiolarian faunas and this country remains one of the most important areas in the world to learn about Lower Palaeozoic radiolarian taxonomy and biostratigraphy. Here we describe a new lower Arenigian radiolarian assemblage and discuss all currently available Ordovician radiolarian data from Kazakhstan. The newly discovered assemblage is curiously oligospecific, despite its good state of preservation. Four morphospecies are recognised, including a new genus and two new species : Inanihella bakanasensis (Nazarov) and I.(?) akzhala n.sp, which characterise the assemblage, together with Triplococcus acanthicus n.gen n.sp. and Proventocitum sp.cf. P. procerulum. This is the oldest radiolarian assemblage from limestone lithologies of Kazakhstan and one of the very few Lower Ordovician assemblages discovered worldwide. We specify in this study the age range of the succeeding Haplentactinia armillata-Proventocitum procerulum assemblage, defined earlier by Nazarov and Popov [1980], which now covers the middle Arenigian – lower Llanvirnian (lower Abereiddian) interval. The succeeding upper Llanvirnian (Llandeilian) Haplentactinia juncta – Inanigutta unica assemblage reported by Nazarov and Popov [1980] reflects a substantial increase in radiolarian diversity, due largely to the introduction of new members of the family Inaniguttidae.

Abstract. Kozur et al. (1996) reported and described some well-preserved Lower Ordovician (Tremadocian) Radiolaria from central Nevada and established several new taxa, among them a new genus Noblella, assigned to the Family Protoentactiniidae Kozur, Mostler &amp; Repetski, 1996. Dr J. K. Page kindly informed us that the genus Noblella already was established for an amphibian genus, Family Brachycephalidae, type species N. peruviana (Noble), byBarbour (1930; p. 81). Therefore, the genus name Noblella Kozur, Mostler &amp; Repetski, 1996 non! Noblella Barbour, 1930, is invalid because of homonymy. We here replace this junior homonym with Paulanoblella Kozur &amp; Repetski, nomen novum.Genus Paulanoblella Kozur &amp; Repetski, nomen novumDerivation. The new name is in honour of noted Radiolaria researcher, Dr Paula Noble, Reno, Nevada.Diagnosis. Unchanged (see Kozur et al., 1996, pp. 255, 266).Holotype.

Abstract. A diverse and well-preserved radiolarian assemblage was extracted from a carbonate sample of latest Darriwilian age from the Shundy Formation of the Aksuran Mountain (North Balkhash Region, Kazakhstan). The fauna is represented by 32 species or morphotypes which belong to nine genera, four families and two orders (Spumellaria and Entactinaria), including four new species described herein (Syntagentactinia? angulata n. sp. Pouille &amp; Danelian, Polyentactinia spinulenta n. sp. Pouille &amp; Danelian, Haplotaeniatum circulus n. sp. Pouille &amp; Danelian and H.? giganteum n. sp. Pouille &amp; Danelian). Representatives of the family Inaniguttidae are particularly abundant, representing c. 70% of the studied assemblage, especially genera Triplococcus and Inanihella that dominate the assemblage. Although the studied fauna contains both of the characteristic species and most of the genera of the previously defined Haplentactinia juncta–Inanigutta unica assemblage, differences in the assemblage structure are striking. The studied fauna also establishes that the two characteristic species of the Inanihella bakanasensis–Triplococcus akzhala assemblage are not restricted to the early–mid-Darriwilian, but their age range also extends to the latest Darriwilian.

Abstract. Rhopalosomatidae, currently considered the sister group of the Vespidae, are an enigmatic family of aculeate wasps that originated in the Late Jurassic or Early Cretaceous. Despite their considerable age, very few fossils of the family have been reported – all of them in amber (Miocene Dominican, Miocene Mexican, and mid-Cretaceous Burmese ambers). Here we report a new mid-Cretaceous rhopalosomatid wasp, Cretolixon alatum Lohrmann, gen. et sp. nov., from Burmese (Kachin) amber. This new genus has a unique mixture of characters, some of which are only known from the recent brachypterous genus Olixon and others of which are known only from the recent macropterous genera. Thus, Cretolixon Lohrmann, gen. nov. not only provides further evidence for the monophyly of the family but also contributes evidence for the monophyly of the Rhopalosomatinae. Key characters of the family are discussed, and an updated checklist of the world genera and fossil species and occurrences of Rhopalosomatidae is provided. Additionally, a chemical analysis was performed for three of the newly reported fossils as well as for the amber piece containing the rhopalosomatid larva described by Lohrmann and Engel (2017) to ascertain their amber vs. copal nature and their affinities with each other and previously described Burmese amber.

Five species of the family Odiidae (Amphipoda), including four new species, are recorded from Japan: Metodius cyanomaculatus sp. nov.; M. leucomaculatus sp. nov.; Postodius albifacies sp. nov.; P. sanguineus sp. nov.; and Antarctodius japonicus Ariyama, 2011. Morphological characters and coloration of these species are described in detail. Metodius gen. nov. is established for the two new species and is characterized by the very short and bare palp of the maxilla 1 and the large gnathopod 2 propodus. Keys to the odiid genera and the Postodius species in the world are provided. The genera can be distinguished from one another by the shapes of maxilla 1, maxilliped, pereopod 7, and telson. The Postodius species differs in the shapes of gnathopod 2, and pereopods 3, 7. Female of A. japonicus is firstly recorded. In this species, the presence of an accessory flagellum and a gill on the coxa 7 is confirmed.

Constitutional System

During the five years that have elapsed since the close of hostilities in World War II, approximately one-half of the nations of the world have adopted new constitutions or have drastically revised existing ones. While some constitutions have been the products of a more or less regular modification, others have marked a revolutionary, though peaceful, development in conformity with Western political traditions. Some have followed the re-emergence of nations in defeat, and others have signalized the birth of new members of the family of nations. Finally, the régimes of the “People’s Democracy” have established instruments of government which are revolutionary both in their origin and their content.

Three New Species

A diverse eutardigrade fauna of the family Eohypsibiidae Bertolani & Kristensen, 1987 was collected on the Faroe Islands. The first record of Bertolanius weglarskae (Dastych, 1972) and new records of Eohypsibius nadjae Kristensen, 1982 are documented. The new genus Austeruseus is established and three new species, Austeruseus faeroensis, nov. sp., A. balduri nov. sp. and A. rokuri nov. sp. are described. The genus differentiates from the genera Bertolanius and Eohypsibius in the buccal tube. The apophyses for the insertion of stylet muscles are (two or six) lateral hooks and the entire length of the mouth and buccal tube are straight in Austeruseus, while Bertolanius and Eohypsibius have the apophyses for the insertion of stylet muscles as crests with ventral and dorsal hooks, and the mouth and buccal tube are flared or trumpet shaped. With five species the Faroese tardigrade fauna is the richest in the world with regard to the family Eohypsibiidae. The genus Austeruseus is primarily found in mosses at high mountain biotopes, and the new genus may be a glacial relic.

Rrna Gene Sequencing

Phenotypic and phylogenetic studies were performed on eight Gram-negative-staining, rod-shaped bacteria isolated from seals. Biochemical and physiological studies showed identical profiles for all of the isolates and indicated that they were related to the family Pasteurellaceae. 16S rRNA gene sequencing demonstrated that the organism represented a distinct cluster with two sublines within the family Pasteurellaceae with <96 % sequence similarity to any recognized species. Multilocus sequence analysis (MLSA) including rpoB, infB and recN genes further confirmed these findings with the eight isolates forming a genus-like cluster with two branches. Genome relatedness as deduced from recN gene sequences suggested that the isolates represented a new genus with two species. On the basis of the results of the phylogenetic analysis and phenotypic criteria, it is proposed that these bacteria from seals are classified as Bisgaardia hudsonensis gen. nov., sp. nov. (the type species) and Bisgaardia genomospecies 1. The G+C content of the DNA was 39.5 mol%. The type strain of Bisgaardia hudsonensis gen. nov., sp. nov. is M327/99/2T ( = CCUG 43067T = NCTC 13475T = 98-D-690BT) and the reference strain of Bisgaardia genomospecies 1 is M1765/96/5 ( = CCUG 59551 = NCTC 13474).
