The tribe Chantiini Pritchard and Baker is proposed for elevation to subfamily status in the family Phytoseiidae. Members of the subfamily Chantiinae are characterized by their unique dorsal chaetotaxy: a combination of five pairs of setae (j3, z2, z3, z4, s4) on the lateral area of the podoscutum, which differs from other phytoseiid species that also have five pairs (j3, z2, z4, s4, s6), and from the more common four (j3, z2, z4, s4) or six (j3, z2, z3, z4, s4, s6) pairs in the family. Two genera, Chantia Pritchard and Baker and Diadromus Athias-Henriot new status, are included in the new sub family. The genus Chantia is monotypic, represented by the type-species C. paradoxa Pritchard and Baker. The genus Diadromus includes four species: D. contiguus (Chant) comb, nov., the type species; D. dominiquae (Schicha and Guttierrez) comb, nov.; D. separatus (Wu and Li) comb. nov.; and D. tengi (Wu and Li) comb. nov. The systematic concept of the new subfamily Chantiinae in relation to other subfamilies in the family Phytoseiidae is outlined. Previous systematic concepts concerning the species in the two genera are reviewed. Keys to the female adults of the genera, the species groups, and the species are provided. Descriptions of each genus and species are given.

A new subfamily, Cydnodromellinae, is proposed in the family Phytoseiidae. Members of the subfamily are characterized by the unique chaetotaxy of the podoscutum, which has five pairs of setae (j3, z2, z4, s4, s6) on its lateral area, with seta z3 absent. There are two genera in this new subfamily. Platyseiella Muma is monotypic, represented by the type-species, P. platypilis (Chant). Cydnodromella Muma includes three species groups and six species: the negevi group (C. negevi (Swirski and Amitai) comb.nov.), the pilosus group (C. pilosus (Chant), type-species of the genus Cydnodromella), and the alveolaris group (C. alveolaris (De Leon) comb.nov., C. borinquensis (De Leon) comb.nov., C. sanictus (De Leon) comb.nov. and C. tunapunensis (De Leon) comb.nov.). Galendromimus Muma and Typhlodromus (Galendromimus) Muma sensu van der Merwe are designated as junior synonyms of the genus Cydnodromella and Cydnoseius cordiae Muma, Typhlodromus medanicus El Badry, and T. zaheri El Badry are designated as junior synonyms of C. negevi. Systematic concepts pertaining to the species in the two genera are reviewed, and descriptions of each genus, species group, and species are given. Keys to the adult females of the species groups in the genus Cydnodromella and to the species in the alveolaris group are provided.

AbstractGenera and previously described species of Nearctic Scythrididae are revised for the first time, based on the study of adult structures. About 90 percent of the Nearctic fauna known in collections consists of undescribed species. The supraspecific taxa treated in this work encompass less than half of the Nearctic species diversity. Only six new species are described, all within the largest and structurally most diverse genus. The status of all nominal species is revised. Valid species are redescribed and their features illustrated. General problems in the systematics of the Scythrididae are discussed. A description of adult features of the family Scythrididae is providad. Extra-limital genera are briefly reviewed. A key to the Nearctic genera and informal supraspecific lineages is provided.Six genera, including three new, are treated: Areniscythris Powell, 1976, Arotrura Walsingham, 1888, Asymmetrura gen. nov., Neoscythris gen. nov., Rhamphura gen. nov., and Scythris s. str. Hübner, [1825]. Areniscythris includes a single described species, Areniscythris brachypteris Powell, but is defined more broadly to account for a number of undescribed species. Arotrura is divided into nine informal species groups with the following included species: Arotrura atascosa sp. nov., Arotrura balli sp. nov., Arotrura divaricata (Braun) comb, nov., Arotrura eburnea Walsingham, Arotrura formidabilis sp. nov., Arotrura hymenata sp. nov., Arotrura longissima sp. nov., Arotrura oxyplecta (Meyrick) comb, nov., Arotrura powelli sp. nov., and Arotrura sponsella (Busck) comb. nov. Asymmetrura includes: Asymmetrura albilineata (Walsingham) comb. nov., Asymmetrura graminivorella (Braun) comb. nov., Asymmetrura impositella (Zeller) comb. nov. and type species, Asymmetrura matutella (Clemens) comb, nov., Asymmetrura reducta (Braun) comb, nov., and Asymmetrura scintillifera (Braun) comb. nov. Neoscythris includes: Neoscythris confinis (Braun) comb, nov., Neoscythris euthia (Walsingham) comb. nov., Neoscythris fissirostris (Meyrick) comb. nov. and type species, and Neoscythris planipenella (Chambers) comb. nov. Rhamphura includes: Rhamphura altisierrae (Keifer) comb, nov., Rhamphura ochristriata (Walsingham) comb. nov. and type species, Rhamphura perspicillella (Walsingham) comb. nov., Rhamphura suffusa (Walsingham) comb. nov., and the extra-limital Rhamphura immunis (Meyrick) comb. nov. from Peru. Scythris s. str. includes: Scythris immaculatella (Chambers) rev. stat., Scythris limbella (Fabricius), Scythris mixaula Meyrick, Scythris trivinctella (Zeller), and Scythris ypsilon Braun. A further eight species are phylogenetically distinct from Scythris s. str. but provisionally are only assigned to five informal monophyletic lineages until their cladistic relationships are more firmly established. These are: the Scythris basilaris lineage including Scythris basilaris (Zeller), Scythris eboracensis (Zeller), and Scythris fuscicomella (Clemens); the Scythris interrupta lineage including Scythris interrupta Braun; the Scythris inspersella lineage including Scythris inspersella (Hübner) and Scythris noricella (Zeller); the Scythris anthracina lineage including Scythris anthracina Braun; and the Scythris charon lineage including Scythris charon Meyrick. Three species are incertae sedis: Scythris inornatella (Chambers) comb, nov., Scythrispilosella (Zeller), and Scythris piratica Meyrick.Coleophora albacostella Chambers and Coleophora inornatella Chambers are transferred from the Coleophoridae. Scythris arizoniella (Kearfott) is transferred to the Coleophoridae [Coleophora arizoniella (Kearfott) comb. nov.].The following new synonymy is proposed: Colinita Busck, 1907 = Arotrura Walsingham, 1888; Gelechia aterrimella Walker, 1864 and Scythris epilobiella McDunnough, 1942 = Scythris inspersella [Hübner, (1817)]; Scythris magnatella Busck, 1904 = Scythris noricella (Zeller, 1843); Scythris pacifica McDunnough, 1927 = Scythris immaculatella (Chambers, 1875); Coleophora albacostella Chambers, 1875 and Scythris hemidictyas Meyrick, 1928 = Neoscythris planipenella (Chambers, 1875).A cladistic definition of the family is presented for the first time. The monophyly of the Scythrididae is supported by the following synapomorphies: very narrow ductus bursae, broad ductus seminalis anastomosed with the oviduct and the corpus bursae, lack of signum, unique shape of the apophyses of the metathoracic furca, tarsomeres 1–4 with two subapical spurs, aedeagus ankylosed, and origin of forewing veins R4 and R5 on a common stalk with R4 extended to the costa and R5 to the termen. Relationships of the Scythrididae within the Gelechioidea are discussed. Based on the cladistic analysis of 52 structural characters, phylogenetic relationships of supraspecific taxa are inferred. Two cladograms, one for the genera and one for the species groups of Arotrura, are presented and used in deriving the classification.

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Abstract Bryozoans with calcified frontal shields formed by the fusion of costae, collectively constituting a spinocyst, are traditionally assigned to the family Cribrilinidae. Today, this family is regarded as nonmonophyletic. In the Argentine Cenozoic, cribrilinids were until recently represented by only two fossil species from the Paleocene of Patagonia. This study describes the first fossil representatives of Jolietina and Parafigularia: J. victoria n. sp. and P. pigafettai n. sp., respectively. A fossil species of Figularia, F. elcanoi n. sp., is also described. The material comes from the early Miocene of the Monte León and Chenque formations (Patagonia, Argentina). For comparison, we also provide redescriptions of the remaining extant species of Jolietina: J. latimarginata (Busk, 1884) and J. pulchra Canu and Bassler, 1928a. The systematic position of some species previously assigned to Figularia is here discussed. Costafigularia n. gen. is erected, with Figularia pulcherrima Tilbrook, Hayward, and Gordon, 2001 as type species. Two species previously assigned to Figularia are here transferred to Costafigularia, resulting in C. jucunda n. comb. and C. tahitiensis n. comb. One species of Figularia is reassigned to Vitrimurella, resulting in V. ampla n. comb. The family Vitrimurellidae is here reassigned to the superfamily Cribrilinoidea. The subgenus Juxtacribrilina is elevated to genus rank. Inferusia is regarded as a subjective synonym of Parafigularia. Parafigularia darwini Moyano, 2011 is synonymized with I. taylori Kuklinski and Barnes, 2009, resulting in Parafigularia taylori n. comb. Morphological data suggest that these genera comprise different lineages, and a discussion on the disparities among cribrilinid (sensu lato) spinocysts is provided.

Concepts of the family Hyolithidae Nicholson fide Fisher and the genera Hyolithes Eichwald and Orthotheca Novak have been expanded through time to encompass a variety of morphologically dissimilar shells. The Hyolithidae is here considered to include only those hyolithid species which have a rounded (convex) dorsum; slopes on the dorsum are inflated, and the venter may be flat or slightly inflated. Hyolithes encompasses species which possess a low dorsum and a prominent longitudinal sulcus along each edge of the dorsum; the ligula is short and the apertural rim is flared. The emended concept of Orthotheca includes only those species of orthothecid hyoliths which have a subtriangular transverse outline and longitudinal lirae covering the shell on both dorsum and venter.Eighteen species of Hyolithes and one species of Orthotheca from the Appalachian region and Western Interior were reexamined in light of more modern taxonomic concepts and standards of quality for type material. Reexamination of type specimens of H. similis Walcott from the Lower Cambrian of Newfoundland, H. whitei Resser from the Lower Cambrian of Nevada, H. billingsi Walcott from the Lower Cambrian of Nevada, H. gallatinensis Resser from the Upper Cambrian of Wyoming, and H. partitus Resser from the Middle Cambrian of Alabama indicates that none of these species represents Hyolithes. Hyolithes similis is here included under the new genus Similotheca, in the new family Similothecidae. Hyolithes whitei is designated as the type species of the new genus Nevadotheca, to which H. billingsi may also belong. Hyolithes gallatinensis is referred to Burithes Missarzhevsky with question, and H. partitus may represent Joachimilites Marek. The type or types of H. attenuatus Walcott, H. cecrops Walcott, H. comptus Howell, H. cowanensis Resser, H. curticei Resser, H. idahoensis Resser, H. prolixus Resser, H. resseri Howell, H. shaleri Walcott, H. terranovicus Walcott, and H. wanneri Resser and Howell lack shells and/or other taxonomically important features such as a complete aperture, rendering the diagnoses of these species incomplete. Their names should only be used for the type specimens until better preserved topotypes become available for study. Morphology of the types of H.? corrugatus Walcott and “Orthotheca” sola Resser does not support placement in the Hyolitha; the affinities of these species are uncertain.

The genus Metallactus has been controversial since its introduction due to the ambiguous nature of the original diagnosis. This has caused some confusion in the taxonomy of Neotropical Pachybrachina. In this work the morphology of endophallus, which is useful for the characterization of species groups in several groups of Coleoptera, including Cryptocephalinae, has been analyzed. This has proven to be a good resource also in the taxonomic treatment of the species belonging to the genus Metallactus. After a careful survey on most of the species described so far, the endophallus shape in Metallactus turned out to be remarkably distinctive and very promising in the delimitation of species groups. The present work includes: a) a new diagnosis of the genus Metallactus on the basis of the aedeagal anatomy; b) the designation of the type species of the nominal genus; c) the revision of a first species-group of the genus, including the type species, hereinafter called Metallactus kollari species-group. Before this revision, catalogues had been reporting 13 species attributable to this group, in the present work three species have been synonymized and seven have been described as new to science. Therefore, the group includes 17 species. The species described as new are: Metallactus rileyi n. sp., M. bellatrix n. sp., M. longicornis n. sp.; M. londonpridei n. sp., M. regalini n. sp., M. bezoar n. sp., M. guarani n. sp. The new synonymies are as follows: Metallactus albipes Suffrian, 1866 (= M. nigrofasciatus Suffrian, 1866 n. syn.), M. albifrons Suffrian, 1866 (= M. flavofrontalis Jacoby, 1907 n. syn.), M. dodecastictus Suffrian, 1866 (= Griburius nigritarsis Jacoby, 1907 n. syn.). The lectotypes of all previously described species have been designated. The new synonymies, the name-bearing type fixations and designations and the nomenclatural acts have been critically discussed. An identification key for the species-group is also provided.

The genus Petasiger which belongs to the family Echinostomidae was proposed by Dietz in 1909, with Petasiger exaeretus as the type species. The description given by Dietz of this species is incomplete and it is proposed therefore to present below a more detailed account of the anatomy, based on an examination of whole mounts and serial sections. The material was obtained from the small intestine of cormorants shot on the coast of Cardigan Bay between Aberystwyth and Llanrhystyd. Five cormorants were shot in July, and of these two contained a large number of Petasiger exaeretus in the small intestine.

Three new species of Chrysomelidae with extraordinary extensions of the male mandibles are described: Scaphodius drehu sp. nov. and S. ferox sp. nov. (Cryptocephalinae), from New Caledonia, and Chaloenus gajah sp. nov. (Galerucinae), from Borneo. Designation of the type species of Chaloenus Westwood, 1861, is clarified. Synonymy of Scaphodius Chapuis, 1874, with Nyetra Baly, 1877, is supported. Four species of Ditropidus Erichson, 1842, described from New Caledonia, but hitherto regarded as nomina nuda, are shown to be available and are placed in Scaphodius: S. aeneus (Fauvel, 1907), comb. nov., S. nitidus (Fauvel, 1907) comb. nov., S. striolatus (Fauvel, 1907) comb. nov., S. sulcatus (Fauvel, 1907) comb. nov. Ditropidus opacicollis Fauvel, 1907, is also transferred to Scaphodius, as S. opacicollis (Fauvel) comb. nov. The genus Ditropidus does not occur onNew Caledonia. Male mandible enlargment in the Chrysomelidae is reviewed: it is common in Cryptocephalinae, but otherwise restricted to a few species of Chrysomelinae, Eumolpinae and Galerucinae. Possible reasons for its distribution in the Chrysomelidae are discussed.

A novel Gram-stain-negative, rod-shaped, yellow bacterium, designated as LB1R16T, was isolated from the Laigu glacier on the Tibetan Plateau, PR China. Strain LB1R16T was catalase-positive, oxidase-negative and grew at 0–28 °C, pH 6.0–8.0 and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain LB1R16T belongs to the family Sphingosinicellaceae but formed an independent lineage. The highest level of 16S rRNA gene sequence similarities were found to Polymorphobacter arshaanensis DJ1R-1T (95.24 %), Sphingoaurantiacus capsulatus YLT33T (94.78 %) and Sandarakinorhabdus limnophila DSM 17366T (94.67 %). The genomic DNA G+C content was 68.8 mol%. The main cellular fatty acids were summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c), summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c), C16 : 0 and C12 : 0-OH. The respiratory quinone was ubiquinone-10. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, one sphingoglycolipid, one unidentified aminolipid, one unidentified phospholipid and two unidentified polar lipids, which were different from the type strains of Polymorphobacter arshaanensis , Sphingoaurantiacus capsulatus and Sandarakinorhabdus limnophila . Based on a polyphasic approach, a novel species of a new genus, Glacieibacterium frigidum gen. nov., sp. nov., within the family Sphingosinicellaceae is proposed. The type strain is LB1R16T (=CGMCC 1.11941T=NBRC 113873T).

A Gram-stain-negative, rod-shaped and facultatively aerobic bacterial strain, designated F7430T, was isolated from coastal sediment collected at Jingzi Wharf in Weihai, PR China. Cells of strain F7430T were 0.3–0.4 µm wide, 2.0–2.6 µm long, non-flagellated, non-motile and formed pale-beige colonies. Growth was observed at 4–40 °C (optimum, 30 °C), pH 6.0–9.0 (optimum, pH 7.5–8.0) and at NaCl concentrations of 1.0–10.0 % (w/v; optimum, 1.0 %). The sole respiratory quinone of strain F7430T was ubiquinone 8 and the predominant cellular fatty acids were summed feature 8 (C18 : 1  ω7c / C18 : 1  ω6c; 60.7 %), summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c; 30.2 %) and C15 : 0 iso (13.9 %). The polar lipids of strain F7430T consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, one unidentified phospholipid and three unidentified lipids. Results of 16S rRNA gene sequences analyses indicated that this strain belonged to the family Halieaceae and had high sequence similarities to Parahaliea aestuarii JCM 51547T (95.3 %) and Halioglobus pacificus DSM 27932T (95.2 %) followed by 92.9–95.0 % sequence similarities to other type species within the aforementioned family. The rpoB gene sequences analyses indicated that the novel strain had the highest sequence similarities to Parahaliea aestuarii JCM 51547T (82.2 %) and Parahaliea mediterranea DSM 21924T (82.2 %) followed by 75.2–80.5 % sequence similarities to other type species within this family. Phylogenetic analyses showed that strain F7430T constituted a monophyletic branch clearly separated from the other genera of family Halieaceae . Whole-genome sequencing of strain F7430T revealed a 3.3 Mbp genome size with a DNA G+C content of 52.6 mol%. The genome encoded diverse metabolic pathways including the Entner–Doudoroff pathway, assimilatory sulphate reduction and biosynthesis of dTDP-l-rhamnose. Based on results from the current polyphasic study, strain F7430T is proposed to represent a novel species of a new genus within the family Halieaceae , for which the name Sediminihaliea albiluteola gen. nov., sp. nov. is proposed. The type strain of the type species is F7430T (=KCTC 72873T=MCCC 1H00420T).
