Three-dimensionally preserved specimens of Late Ordovician graptolites have been isolated from Vauréal Formation limestone samples collected from Anticosti Island, Quebec. The morphology, astogeny, and systematics of Anticostia macgregorae n.gen., n.sp. are described. These specimens show a new astogenetic pattern (pattern K) described for the first time. The similar glyptograptid species Glyptograptus hudsoni Jackson, Glyptograptus tenuissimus Ross and Berry, and Orthograptus fastigatus Davies all possess a pattern K astogeny. These species, along with Glyptograptus lorrainensis, which possesses the less-derived pattern G astogeny, are included within Anticostia n.gen. Anticostia tenuissima (Ross and Berry) is redescribed and Normalograptus? occidentalis (Ruedemann) is refigured based on their type specimens from coeval rocks in Nevada and Idaho.

Uninterrupted, ~800 m thick, Ashgill through Llandovery carbonate strata from Anticosti Island (eastern Canada) reveal five new brachiopod genera, enhancing present knowledge about the early evolution of the spire-bearing order Atrypida, spanning some 10.2 million years of time, and a global mass extinction crisis. New taxa include smooth-shelled forms such as the Late Ordovician genus Xysila, type X. astaca n. sp., and two new Early Silurian genera, Becscia, type B. scissura n. sp., and Cerasina, type C. pycnata n. sp. New costate genera include the Early Silurian reef-dwelling form Dihelictera, type D. acrolopha n. sp., and a deeper water inhabitant, Joviatrypa, type J. brabyla n. sp. For comparison with these new taxa, the spiralia and jugal processes of the type species of the Llandovery genera Protatrypa and Meifodia are illustrated and described for the first time.

Netelia morleyi Townes, Townes & Gupta 1961 is transferred from the subgenus Netelia Gray 1860 to the subgenus Paropheltes Cameron 1907. One new replacement name is proposed: Aleiodes philippinensis nom. nov. for Rhogas lateralis Baker 1917, nec Troporhogas lateralis Cameron 1905. Lectotypes are designated for Antrusa persimilis Nixon 1954, Rhyssalus striatulus Cameron 1909, Troporhogas trimaculata Cameron 1905, Hemiteles cingulatorius Morley 1912, Paniscus ferrugineus Cameron 1889 and for Xanthojoppa inermis Morley 1917. Some previously overlooked type specimens are interpreted and illustrated and some errors in the literature corrected. Hosts are recorded for two genera of Ichneumoninae for the first time: Catadelphops nasutus (Heinrich 1962) was reared from Proserpinus terlooii (Edwards 1875) (Lepidoptera: Sphingidae) in the USA, and Aethianoplis excavata (Roman 1910) was reared from Precis octavia (Cramer 1777) (Lepidoptera: Nymphalidae) in Uganda.

Early American acarologists proposed several species that have been recombined to the oribatid mite genus Epidamaeus (Damaeidae), but none has been redescribed to modern standards. These include E. puritanicus (Banks, 1906), E. michaeli (Ewing, 1909), E. globifer (Ewing, 1913), E. florida (Wilson, 1936), E. olitor (Jacot, 1937), and E. craigheadi (Jacot, 1939). We redescribe and illustrate these species, based on available type specimens and other material in various collections, and give an indication of their overall distributions. Juvenile instars are at least partly described for all except E. florida and E. olitor. Since these six collectively include the most encountered Epidamaeus species in the eastern USA, a diagnostic key is presented that also includes E. arcticola (Hammer, 1952), which is reliably recorded from eastern North America (New Hampshire) for the first time. A neotype is selected for E. michaeli, which is considered a senior subjective synonym of E. canadensis (Banks, 1909) [new syn.]. Synonymy of E. puritanicus with E. grandjeani (Bulanova-Zachvatkina, 1957) is rejected.

The present study redescribes four species of Neanthes Kinberg, 1865 (Nereididae de Blainville, 1818) based on their type specimens collected from different worldwide localities: Neanthes chilkaensis (Southern, 1921) from India, N. galetae (Fauchald, 1977) from Panama, N. helenae (Kinberg, 1865) from St Helena Island, and N. mossambica (Day, 1957) from Mozambique. The morphology of the types was re-examined for the first time after the species were originally described, and incorporated the recent improvements in the standards and terminology for describing nereidid features. The arrangement of paragnaths on area VI stood out among the diagnostic features used to distinguish these four species. Neanthes chilkaensis and N. helenae are the unique nereidids bearing p-bar paragnaths on the area VI. Both species are also distinctive as the former species only exhibited p-bar paragnaths on the area VII–VIII and the latter ventrolateral projections on the apodous segment. Further examination revealed that N. nanciae (Day, 1949) from St Helena is a junior synonym of N. helenae. Moreover, N. galetae and N. mossambica are distinguishable from other species also by the development of dorsal cirri, neuropodial postchaetal lobe and ventral ligule, the presence/absence of merged paragnaths on area IV, paired oesophageal caeca, among other features. This study has further contributed to the morphological delimitation of the species in Neanthes as a first step towards revising the genus.

Eleven Species

The collections of fungus gnats by Johan Wilhelm Zetterstedt (1785–1874), lodged in the Museum of Zoology in Lund, Sweden, are examined for all species belonging in the tribe Exechiini Edwards. The majority of the material was collected in Fennoscandia, mainly in Sweden, in the first half of the 19 th century. Altogether 37 species of the tribe Exechiini could be safely identified. Three additional species are strongly indicated to be present in the collections, but could not be identified with certainty, viz. Allodia (Brachycampta) alternans (Zetterstedt, 1838), Cordyla murina Winnertz, 1863 and Stigmatomeria crassicornis (Stannius, 1831). Some of Zetterstedt's types have been erroneously synonymized and misinterpreted in modern literature. Hence, illustrations of terminalia are presented for all recognizable Exechiini types described by Zetterstedt. In order to preserve nomenclatural stability a lectotype is selected for Brevicornu griseolum (Zetterstedt, 1852) sensu auctore nec Edwards, and a neotype is selected for Allodia (Brachycampta) alternans (Zetterstedt, 1838). Two species names are reinstated, viz. Brevicornu canescens (Zetterstedt, 1852) sp. restit. stat. n. and Notolopha brachycera (Zetterstedt, 1838) sp. restit. stat. n. Two new synonyms are established, viz. Notolopha brachycera (Zetterstedt, 1838) = Allodiopsis (Notol- opha) tuomikoskii Zaitzev & Maximova, 2000 syn. n., and Brevicornu griseolum (Zetterstedt,1852) = Brevicornu boreale (Lundström, 1914) syn. n. All type specimens of Brevicornu fusculum (Zetterstedt, 1838) have lost their abdomens. No material of Exechia parvula (Zetterstedt, 1852) or Cordyla canescens Zetterstedt, 1852 could be located in the collections. Although the type material of Exechia parvula probably is lost, the name is still valid as a junior synonym for Mycetophila nana Staeger, 1840 since Mycetophila nana Staeger, 1840 is a junior primary homonym of Mycetophila nana Macquart, 1826. Cordyla canescens has been made a junior synonym for Stigmatomeria crassicornis (Stannius, 1831). The identity of Brevicornu fusculum is highly uncertain and the name must remain as a nomen dubium. Eleven species are reinstated or correctly reported from Sweden for the first time: Allodia (Allodia) tuomikoskii Hackman, 1971, Allodia (Allodia) zaitzevi Kurina, 1998, Allodiopsis rustica (Edwards, 1941), Brevicornu canescens (Zetterstedt, 1852), Brevicornu nigrofuscum (Lundström, 1909), Exechiopsis (Xenexechia) crucigera (Lundström, 1909), Pseudexechia aurivernica Chandler, 1978, Notolopha brachycera (Zetterstedt, 1852) Synplasta gracilis (Winnertz, 1863), Tarnania dziedzickii (Edwards, 1941), and Tarnania nemoralis (Edwards, 1941).

Background and Aims: Gustavia sessilis is a neotropical tree, belonging to the Lecythidaceae family, until now known from the Colombian Chocó region only. In this paper, we report G. sessilis for the first time for Central America. Methods: Central American specimens of G. sessilis were collected in 2019 from the Darién Province (eastern Panama). Plant identifications were confirmed by comparing collected specimens with those identified earlier and housed in the MO, PMA, SCZ and UCH herbaria. Type specimens were examined by consulting the JSTOR Global Plants database. The estimations of the conservation status were made based on the criteria of the IUCN.Key results: The record of G. sessilis for Central America is presented, based on a collection made from eastern Panama (Darién Province). Photographs, taxonomic comments, and conservation notes are provided. Additionally, a key for the Central American Gustavia species is included.Conclusions: The distribution of G. sessilis now ranges from Bahía Piñas, Darién Province, Panama to the Condoto river, Chocó region, Colombia, highlighting the importance of the Chocó Panama-Colombia region for the conservation of biodiversity, since it could act as a natural corridor for species. Taking into account the small number of records and the restricted natural range of this species, we recommend considering G. sessilis as an endangered species.

AbstractDiaphanocephalus galeatus collected from the small intestine of the lizard Dracaena paraguayensis in the Pantanal wetlands, State of Mato Grosso do Sul, Brazil, is redescribed. Genetic characterization and observations using scanning electron microscopy (SEM) were performed for the first time. The vouchers of D. galeatus and the type specimens of its congeners, deposited in the Coleção Helmintológica do Instituto Oswaldo Cruz (CHIOC), were consulted. Light and SEM observations revealed several undescribed features of D. galeatus, i.e. structure of the cephalic end and of the buccal capsule, position and morphology of deirids, presence of phasmids in females and presence of unpaired papilla on the membranous projection that covers the genital cone in males. After observation of the specimens deposited in the helminthological collection, D. jacuruxi is considered a synonym of D. galeatus, and D. diesingi, despite its incomplete description, is tentatively retained as valid due to the poor condition of the type material. The results also indicated low host specificity of D. galeatus, contradicting previous assertions. Genetic comparisons using patristic distances and phylogenetic trees generated from sequences of the 28S rRNA nuclear gene indicated that D. galeatus is closer to the taxa within Ancylostomatoidea and Strongyloidea than any lineage of Metastrongyloidea or Trichostrongyloidea. However, most of the nodal supports were low. Based on the genetic and morphological characterization, the validity of D. galeatus was confirmed. These data may serve for further comparative approaches for different populations of the parasite, from different hosts in different geographical areas, mitigating taxonomic confusions.
