AbstractThe Holarctic species of the genus Pygocryptus Roman (Hymenoptera: Ichneumonidae) are revised. Two previously recognized species, P. grandis from Europe and P. echthroides from North America, are retained; four new species and three subspecies for P. echthroides are proposed. A diagnostic key and descriptions of the new species and subspecies are presented.

A long tradition of separate Nearctic and Palaearctic taxonomic studies of the diverse aleocharine rove beetles (Coleoptera: Staphylinidae) has obscured the recognition of Holarctic species and detection of adventive species in both regions. Recently, integrated study of the two regions through detailed morphological comparisons and development of an authoritatively identified DNA barcode reference library has revealed the degree to which these two aleocharine faunas are interconnected, both naturally and through human activity. Here this approach is adopted to recognize new species, reveal Holarctic species, and recognize adventive species in both North America and Europe. The following new species are described: Isoglossa triangularis Klimaszewski, Brunke & Pentinsaari, sp. nov. from British Columbia; Gnypeta impressicollis Klimaszewski, Brunke & Pentinsaari, sp. nov., from Ontario, Maryland and North Carolina; Aloconota pseudogregaria Klimaszewski, Brunke & Pentinsaari, sp. nov., from Ontario and Virginia; and Philhygra pseudolaevicollis Klimaszewski, Brunke & Pentinsaari, sp. nov. from eastern Canada. Dasygnypeta velata and Philhygra angusticauda are revealed to be Holarctic species, resulting in the following synonymies: Dasygnypeta velata (Erichson, 1839) = Gnypeta minuta Klimaszewski & Webster, 2008, syn. nov. and Philhygra angusticauda (Bernhauer, 1909) = Atheta (Philhygra) pinegensis Muona, 1983, syn. nov. The Nearctic species Hylota ochracea (and genus Hylota), Thecturota tenuissima, and Trichiusa robustula are newly reported from the Palaearctic region as adventive, resulting in the following synonymies: Hylota ochracea Casey, 1906 = Stichoglossa (Dexiogyia) forticornis Strand, 1939, syn. nov.; Thecturota tenuissima Casey, 1893 = Atheta marchii Dodero, 1922, syn. nov.; and Trichiusa robustula Casey, 1893 = T. immigrata Lohse, 1984, syn. nov. The Palaearctic species Amarochara forticornis, Anomognathus cuspidatus, Oligota pumilio, and Parocyusa rubicunda are newly confirmed from the Nearctic region as adventive, resulting in the following synonymies: Parocyusa rubicunda (Erichson, 1837) = Chilopora americana Casey, 1906, syn. nov. and Anomognathus cuspidatus (Erichson, 1839) = Thectura americana Casey, 1893, syn. nov. The genus Dasygnypeta, sensu nov. is newly reported from North America, Paradilacra is newly reported from eastern North America, and Haploglossa is newly reported from Canada, resulting in the following synonymy: Paradilacra densissima (Bernhauer, 1909) = Gnypeta saccharina Klimaszewski & Webster, 2008, syn. nov. Native Cyphea wallisi is newly reported from across Canada and C. curtula is removed from the Nearctic fauna. The status of both Gyrophaena affinis and Homalota plana is uncertain but these species are no longer considered to be adventive in North America. Three new combinations are proposed: Dasygnypeta baranowskii (Klimaszewski, 2020) and D. nigrella (LeConte, 1863) (both from Gnypeta) and Mocyta scopula (Casey, 1893) (from Acrotona). Dolosota Casey, 1910, syn. nov. (type species Eurypronota scopula Casey), currently a subgenus of Acrotona, is therefore synonymized with Mocyta Mulsant & Rey, 1874. Additionally, four new Canadian records and 18 new provincial and state records are reported.

AbstractThe status of Anarta cordigera (Thunberg, 1788), formerly treated as a circumboreal holarctic species, is reassessed in the light of characters of the male vesica and female bursa copulatrix. Populations are arranged in four species: A. cordigera in Europe; A. carbonaria Christoph, 1893 in Siberia and the Far East; A. luteola Grote and Robinson, 1865 in North America; and A. macrostigma Lafontaine and Mikkola, new species, in western North America. Adults and genitalia are illustrated for the four species.

As part of ongoing studies on Magnolia sect. Macrophylla in North America (Mexico), unusual populations from the humid forests of Sierra Madre Oriental (central western Tamaulipas State) were found. They are here formalized as a new species, M. alejandrae. Its morphology, ecology, and conservation status are provided. A morphological comparison with similar species and diagnostic key for the species of M. sect. Macrophylla are also included. The names Magnolia ashei, M. macrophylla, and M. dealbata are lectotypified, respectively, on specimens preserved at NCU, and P and on a Zuccarini illustration. An epitype (at M) was chosen for M. dealbata.

To date, only one species of Temnocephala is known from Chile, Temnocephala chilensis, and three from southern Argentina (Patagonia), namely T. chilensis, Temnocephala dionii, and Temnocephala mexicana. Here we describe a new species of Temnocephala and provide an updated description of T. chilensis based on material found on an anomuran crab (Aeglidae) from southern Chile. Additional hosts and localities are reported for both species in southern Argentina and Chile, and a diagnostic key for all species of Temnocephala hosted on Aegla and Parastacidae is included as well. In southern Chile, both T. chilensis and the new species were found on the crayfish Samastacus spinifrons and on the anomuran crabs Aegla abtao and Aegla alacalufi; in addition, the new species was found on Aegla manni, and T. chilensis on Aegla rostrata. In southern Argentina, T. chilensis and the new species were found on Aegla riolimayana and S. spinifrons. Based on their shared traits (morphology of the penial stylet, host preferences and geographic distribution), the temnocephalans hosted in Aegla are tentatively gathered into two clusters, the Chilensis and Axenos groups.

AbstractAn assemblage of 50 species of small shelly fossils is described from Cambrian Series 2 (Stage 4) strata in North Greenland, the present day northernmost part of the paleocontinent of Laurentia. The fossils are derived from the basal member of the Aftenstjernesø Formation at Navarana Fjord, northern Lauge Koch Land, a condensed unit that accumulated in a sediment-starved outer ramp setting in the transarctic Franklinian Basin, on the Innuitian margin of Laurentia. Most other small shelly fossil assemblages of similar age and composition from North America are described from the Iapetan margin of Laurentia, from North-East Greenland south to Pennsylvania. Trilobites are uncommon, but include Serrodiscus. The Australian bradoriid Spinospitella is represented by a complete shield. Obolella crassa is the only common brachiopod. Hyoliths, including Cassitella, Conotheca, Neogloborilus, and Triplicatella, are abundant and diverse, but most are represented just by opercula. Sclerites interpreted as stem-group aculiferans (sachitids) are conspicuous, including Qaleruaqia, the oldest described paleoloricate, Ocruranus?, Inughuitoconus n. gen., and Hippopharangites. Helcionelloid mollusks are diverse, but not common; they are associated with numerous specimens of the bivalve Pojetaia runnegari. The fauna compares best with that of the upper Bastion Formation of North-East Greenland, the Forteau Formation of western Newfoundland, and the Browns Pond Formation of New York, but several taxa have a world-wide distribution. Many specimens are encrusted with crystals of authigenic albite. New species: Anabarella? navaranae, Stenotheca? higginsi, Figurina? polaris, Hippopharangites groenlandicus, Inughuitoconus borealis, and Ocruranus? kangerluk.UUID: http://zoobank.org/160a17b1-3166-4fcf-9849-a3cabd1e04a3

AbstractIn midcontinent North America, the Fox Hills Formation (Upper Cretaceous, upper Maastrichtian) preserves the last marine faunas in the central Western Interior Seaway (WIS).Neritoptyx hogansoninew species, a small littoral snail, exhibited allometric change from smooth to corded ornament and rounded to shouldered shape during growth. Specimens preserve a zig-zag pigment pattern that changes to an axial pattern during growth.Neritoptyx hogansoninew species was preyed on by decapod crustaceans, and spent shells were occupied by pagurid crabs. Dead mollusk shells, particularly those ofCrassostrea subtrigonalis(Evans and Shumard, 1857), provided a hard substrate to which they adhered on the Fox Hills tidal flats. This new neritimorph gastropod establishes a paleogeographic and chronostratigraphic proxy for intertidal conditions on the Dakota Isthmus during the late Maastrichtian. Presence of a neritid extends the marine tropical/temperate boundary in the WIS northward to ~44° late Maastrichtian paleolatitude. Late Maastrichtian closure of the isthmus subsequently altered marine heat transfer by interrupting northward flow of tropical currents from the Gulf Coast by as much as 1 to 1.5 million years before the Cretaceous ended.UUID:http://zoobank.org/3ba56c07-fcca-4925-a2f0-df663fc3a06b

SUMMARYGiven the worldwide decline of amphibian populations due to emerging infectious diseases, it is imperative that we identify and address the causative agents. Many of the pathogens recently implicated in amphibian mortality and morbidity have been fungal or members of a poorly understood group of fungus-like protists, the mesomycetozoans. One mesomycetozoan, Amphibiocystidium ranae, is known to infect several European amphibian species and was associated with a recent decline of frogs in Italy. Here we present the first report of an Amphibiocystidium sp. in a North American amphibian, the Eastern red-spotted newt (Notophthalmus viridescens), and characterize it as the new species A. viridescens in the order Dermocystida based on morphological, geographical and phylogenetic evidence. We also describe the widespread and seasonal distribution of this parasite in red-spotted newt populations and provide evidence of mortality due to infection.
