The Batocrinidae was a component of the North America Early Mississippian crinoid fauna and a significant contributor to the global biodiversity spike referred to as the “Age of Crinoids.” All batocrinids are North American, and all but one species are confined to the Tournaisian and Visean. In this contribution, genera are objectively defined on discrete characters, and the generic assignment of all valid species is re-evaluated. A phylogenetic hypothesis is presented for relationships within the Batocrinidae based on parsimony-based analyses and known stratigraphic ranges.Fifteen basic batocrinid architectural designs are recognized as genera, and four new genera are described:Glannearycrinusn. gen.,Gongylocrinusn. gen,Magnuscrinusn. gen., andSimatocrinusn. gen.Batocrinuswas a catch-all genus for any Mississippian camerate with tetragonal first primibrachials and an anal tube; thus, many late 19thcentury species are in need of a modern generic assignment. In this contribution, 61 percent of the 166 currently valid batocrinid species are reassigned to different genera. In addition,Sunwaptacrinusis transferred to the Batocrinidae, six species are transferred out of the Batocrinidae, and five species are designated as nomina dubia.

Some specimens of Chaetogaster diastrophus may have dorsal seatae; there is no need for the separation of such individuals under the name Pseudochaetogaster longmeri. Amphichaeta leydigii and A. americana are recorded and Homochaeta raptisae is transferred to this genus. The source of the confusion between Vejdovskyella comata and V. intermedia is identified and both are now accepted as valid species and are recorded from Washington and British Columbia, respectively. Vejdovskyella hellei is transferred to Specaria. The distinction between Nais communis and N. variabilis is documented, and the serrate nature of the hair setae of N. elinguis is newly described. Pristina idrensis is new to the Canadian fauna; P. aequiseta is new to British Columbia and Washington. The few remaining differences between our records and those presented by other workers are catalogued, yielding a total of 65 confirmed species and two probable additions to the North American fauna.

AbstractThe tribe Coryphiini Hatch is redefined to include six genera and 18 species from North America. Two new genera are described: Gnathoryphium (type-species G. mandibulare n. sp.) and Holoboreaphilus (type-species Boreaphilus nordenskioeldi Maklin). Seven new species are described: Coryphium nigrum from the northeastern United States and Subhaida californica, S. aptera, S. monticola, S. utahensis, S. sinuata, and Gnathoryphium mandibulare from western North America. The genus Occiephelinus Hatch from western North America and Planeboreaphilus Shibata from Japan are considered junior synonyms of Coryphium Stephens. The western North American species formerly placed in Ephelinus Cockerell are transferred to the genus Coryphium. Pseudohaida ingrata Hatch is transferred to the genus Subhaida Hatch. Boreaphilus americanus Notman is placed in synonymy with B. henningianus C.R. Sahlberg.All genera and species are described. Habitus drawings, and line drawings of the antenna, labrum, maxilla, mandible, mentum, and labium are presented for at least one species of each genus. The aedeagus is illustrated for all the species except two that are known only from females.Of the species treated, three are Holarctic in distribution, four are restricted to eastern North America, and 11 are endemic to the mountainous areas of western North America.All available biological information for each species is included and a key is presented to aid in the identification of all the genera and species of the tribe in North America.

Generic Unit

The genus Aleurodiscus Rabenh. ex J. Schroet. (sensu lato) is an artificial assemblage of large-spored 'thelephoraceous' hymenomycetes, which can no longer be maintained as a generic unit. The generic limits and the taxonomic position of Aleurodiscus (sensu stricto) (TYPE SPECIES: A. amorphus (Pers. per Purt.: Fr.) J. Schroet.) have been discussed by the writer (1964) in a separate paper. The present work supplements this earlier work, but is concerned primarily with an appraisal of the non-amyloid-spored Aleurodisci, all of which are removed from Aleurodiscus and either assigned to other recognized genera or relegated to new genera.Accordingly, two new genera and 15 new combinations are devised here to accommodate several species formerly placed in Aleurodiscus (sensu lato). The new genera, one of which is monotypical, are Aleurocorticium Lemke, gen. nov. (TYPE SPECIES: A. acerinum (Pers. per Fr.) Lemke, gen. & comb. nov.) and Licrostroma Lemke, gen. nov. (MONOTYPE: L. subgiganteum (Berk.) Lemke, gen. & comb. nov.). The additional 13 combinations proposed are Aleurocorticium album (Viégas) Lemke, comb, nov., A. alliaceum (Quél.) Lemke, comb. nov., A. candidum (Schw.) Lemke, comb. nov. A. dryinum (Pers.) Lemke, comb. nov., A. griseo-canum (Bres.) Lemke, comb. nov., A. lepra (Berk. et Curt.) Lemke, comb. nov., A. macrodens (Coker) Lemke, comb. nov., A. macrosporum (Bres.) Lemke, comb. nov., A. moquiniarum (Viégas) Lemke, comb. nov., A. nivosum (Berk. et Curt. ex Höhn. et Litsch.) Lemke, comb. nov., A. seriatum (Berk. et Curt.) Lemke, comb. nov., A. strumosum (Fr.) Lemke, comb. nov.; and Aleurocystis magnispora (Burt) Lemke, comb. nov.The genus Laeticorticium Donk (1956: 16) (TYPE SPECIES: L. roseum (Pers. per Fr.) Donk) is confirmed as a valid segregate from Aleurodiscus (sensu lato), but the species of Laeticorticium are not treated here aside from nomenclatural considerations. With the exception of the Laeticorticia, all of the remaining North American and many of the critical non-amyloid-spored species of Aleurodiscus (sensu lato) are reviewed.Particular emphasis is devoted to the genus Aleurocorticium Lemke, gen. nov. and a key to 14 North American species of Aleurocorticium is provided. Seven of the Aleurocorticia are reported from the North American mycobiota for the first time. These seven species, five of which are described as new to science, include Aleurocorticium alliaceum (Quél.) Lemke [= Aleurodiscus alliaceus (Quél) Boidin (1957)], Aleurocorticium dryinum (Pers.) Lemke [= Aleurodiscus dryinus (Pers.) Bourd,], Aleurocorticium incrustans Lemke, sp. nov., A. maculatum Jacks. et Lemke, sp. nov., A. mexicanum Lemke, sp. nov., A. microsporum Jacks. et Lemke, sp. nov., and A. pachysterigmatum Jacks. et Lemke, sp. nov.Corlicium hiemale [= Aleurodiscus hiemalis (Laurila) Eriksson (1958a: 78)] is, likewise, initially recorded for North America.Eight of the named species of Aleurodiscus are recognized as facultative synonyms. These names, as indicated, are offered as taxonomic discards: [Aleurodiscus albidus Massee =] Aleurocorticium lepra (Berk. et Curt.) Lemke; [Aleurodiscus albus (Burt) Rogers et Jacks. =] Xenasma clematidis (Bourd. et Galz.) Liberta; [Aleurodiscus guttulatus Rick =] Bourdotia cinerea (Bres.) Bourd. etGalz.; [Aleurodiscus jacksonii Ahmad =] Aleurocorticium candidum (Schw.) Lemke; [Aleurodiscus orientalis Lloyd =] Licrostroma subgiganteum (Berk.) Lemke; [Aleurodiscus reflexus Yasuda =] Licrostroma subgiganteum (Berk.) Lemke; [Aleurodiscus sendaiensis Yasuda =] Corticium evolvens (Fr. ex Fr.) Fr.; [Aleurodiscus subacerinus Höhn. et Litsch. =] Aleurocorticium alliaceum (Quél.) Lemke.The genus Cyphella Fr. (MONOTYPE: C. digitalis (Alb. et Schw. per Pers.) Fr.) is reinstated (see Code 1952: 76) and the combination Aleurodiscus digitalis (Alb. et Schw. per Pers.) Donk (1951: 210) is discredited.

Ciliary Dyskinesia

Primary Ciliary Dyskinesia (PCD) is a rare, under-recognized disease that affects respiratory ciliary function, resulting in chronic oto-sino-pulmonary disease. The PCD clinical phenotype overlaps with other common respiratory conditions and no single diagnostic test detects all forms of PCD. In 2018, PCD experts collaborated with the American Thoracic Society (ATS) to create a clinical diagnostic guideline for patients across North America, specifically considering the local resources and limitations for PCD diagnosis in the United States and Canada. Nasal nitric oxide (nNO) testing is recommended for first-line testing in patients ≥5 years old with a compatible clinical phenotype; however, all low nNO values require confirmation with genetic testing or ciliary electron micrograph (EM) analysis. Furthermore, these guidelines recognize that not all North American patients have access to nNO testing and isolated genetic testing is appropriate in cases with strong clinical PCD phenotypes. For unresolved diagnostic cases, referral to a PCD Foundation accredited center is recommended. The purpose of this narrative review is to provide insight on the North American PCD diagnostic process, to enhance the understanding of and adherence to current guidelines, and to promote collaboration with diagnostic pathways used outside of North America.

Multituberculates, though among the most commonly encountered mammalian fossils of the Mesozoic, are poorly known from the North American Early Cretaceous, with only one taxon named to date. Herein we describe Argillomys marylandensis, gen. et sp. nov., from the Early Cretaceous of Maryland, based on an isolated M2. Argillomys represents the second mammal known from the Arundel Clay facies of the Patuxent Formation (Lower Cretaceous: Aptian). Though distinctive in its combination of characters (e.g., enamel ornamentation consisting of ribs and grooves only, cusp formula 2:4, presence of distinct cusp on anterobuccal ridge, enlargement of second cusp on buccal row, central position of ultimate cusp in lingual row, great relative length), the broader affinities of Argillomys cannot be established because of non-representation of the antemolar dentition. Based on lack of apomorphies commonly seen among Cimolodonta (e.g., three or more cusps present in buccal row, fusion of cusps in lingual row, cusps strongly pyramidal and separated by narrow grooves), we provisionally regard Argillomys as a multituberculate of “plagiaulacidan” grade. Intriguingly, it is comparable in certain respects to some unnamed Paulchoffatiidae, a family otherwise known from the Late Jurassic – Early Cretaceous of the Iberian Peninsula.

Jurassic Ophiolites

<p>The western edge of the North America plate contains geological records that formed during the long-lived convergence between plates of the Panthalassa Ocean and North America. The geology of different segments along western North America indicates different polarities (eastward and westward) for subducted slabs and thereby various tectonic histories and settings. The western United States (together with Mexico) plays a key role in this debate, many geologic interpretations assume continuous eastward subduction in contrast to observations within proximal geologic segments and tomographic images of the lower mantle below North America and the eastern Pacific Ocean which suggest a more complex subduction history. In this study, we aim to evaluate the plate tectonic setting in which the Jurassic ophiolites of California formed. Geochemical data from these ophiolites suggest that they formed above a nascent intra-oceanic or continental margin subduction zone. We first developed a kinematic reconstruction of the western US geology back to the Jurassic based on published structural geological data. Importantly, we update the reconstruction of the various branches of the San Andreas fault system to determine the relative position of the ophiolite fragments and adopt a previous restoration of Basin and Range extension which we expand northward towards Washington state. We then reconstruct North American margin deformation associated with Cretaceous to Paleogene shortening and strike-slip faulting. We find no clear candidates in the geological record that may have accommodated major subduction between the Jurassic ophiolite belt and the North American margin and consequently concur with the school of thought that considers that the ophiolite belt, as well as the underlying subduction-accretionary Franciscan Complex, likely formed in the North American fore-arc. We collected paleomagnetic data to reconstruct the spreading direction of the Jurassic Californian ophiolites, by providing new paleomagnetic data from sheeted dykes of the Josephine and Mt. Diablo Ophiolites. These suggest a NE-SW paleo-ridge orientation, oblique to the North American margin which may be explained by partitioning of a dextral component of subduction obliquity relative to North America. We used this spreading direction in combination with published ages of the ophiolites and our restoration of the relative position of these ophiolites prior to post-Jurassic deformation to construct a ridge-transform system at which the Jurassic ophiolites accreted. The results will be used to evaluate which parts of the subduction systems that existed in the eastern Panthalassa Ocean may reside in the western US, and which parts may be better sought in the northern Canadian Segment or/and in the southern Caribbean region.</p>

AbstractThe North American Aegeriidae are revised on the basis of the study of late-instar larvae of about 60 species. These species represent 20 genera in five tribes in two subfamilies: Bembeciini, Zenodoxini, Aegeriini and Melittiini in Zenodoxinae and Synanthedontini in Synanthedontinae. The presently recognized genera, Ramosia Engelhardt, Conopia Hübner and Thamnosphecia Spuler are reduced to synonyms of Synanthedon Hübner. Three new genera are defined by larval characters but are referred to only as Genera I, II and III. Larval characters for most of the species are discussed and illustrated; keys to species, genera and tribes are provided. Tribes, genera and most species are arranged in the text as nearly as possible according to their phylogenetic relationships as suggested by the larvae.
