AbstractThe paper describes a new species and genus of fly, Archidipteron walkeri (Nymphomyiidae: Diptera), found in samples seined by screens from the Molus river, New Brunswick, after spraying of the watershed with DDT in oil.The species is compared with Nymphomyia alba, Tokunaga, of Japan and the affinities of the family discussed. It was concluded that these insects are only distantly related to other Diptera and are probably best considered as belonging in the Archidiptera, a suborder of the Diptera, as proposed by Rohdendorf.The ecological position of the insects is discussed but definite conclusions are not drawn pending more information on life cycle, particularly of the, as yet unknown, larval stages.

A new species, Pholis clemensi, referred to the family Pholidae, is named and described from 12 specimens taken in southern British Columbia waters and the Strait of Juan de Fuca. Pholis clemensi is compared with other members of the genus, and a key is given to the North American species.

Peniculus asinus, a new species of copepod parasitic on Sebastes (Pisces: Teleostei) off the Pacific coast of Canada is described and illustrated. The copepod is an unique member of its genus in that it possesses cephalothoracic holdfast processes. The discovery of a Peniculus with these processes is taken as evidence confirming the place of this genus in the family Pennellidae.

Silicified material from the Early Caradoc part of the Las Aguaditas Formation in San Juan Province, Argentina, includes a nearly complete growth series for a new species of the tropidocoryphid Stenoblepharum Owens, 1973. Cladistic analysis of Stenoblepharum species indicates that S. astinii new species is most closely allied to the Early Caradoc S. strasburgense (Cooper, 1953) from Virginia. Chinese species of Stenoblepharum are sister group to a Baltic/Laurentian clade. A single adult-like protaspid stage occurs in the life cycle of S. astinii, closely resembling the protaspis of Decoroproetus. It is preceded by a non-adult-like first protaspid instar that appears to be characteristic of Proetoidea in general but contrasts markedly with the early larval stages of other taxa in Proetida.

A new species of Apatemyidae,Sinclairella simplicidens, is based on four isolated teeth that were screenwashed from fissure fillings at the late Oligocene Buda locality, Alachua County, Florida. Compared to its only congenerSinclairella dakotensis, the new species is characterized by upper molars with more simplified crowns, with the near absence of labial shelves and stylar cusps except for a strong parastyle on M1, loss of paracrista and paraconule on M2 (paraconule retained but weak on M1), lack of anterior cingulum on M1–M3, straighter centrocristae, smaller hypocone on M1 and M2, larger hypocone on M3, distal edge of M2 continuous from hypocone to postmetacrista supporting a large posterior basin, and with different tooth proportions in which M2 is the smallest rather than the largest molar in the toothrow. The relatively rare and poorly-known family Apatemyidae has a long temporal range in North America from the late Paleocene (early Tiffanian) to early Oligocene (early Arikareean). The new species from Florida significantly extends this temporal range by roughly 5 Ma to the end of the Paleogene near the Oligocene-Miocene boundary (from early Arikareean, Ar1, to late Arikareean, Ar3), and greatly extends the geographic range of the family into eastern North America some 10° of latitude farther south and 20° of longitude farther east (about 2,200 km farther southeast) than previously known. This late occurrence probably represents a retreat of this subtropically adapted family into the Gulf Coastal Plain subtropical province at the end of the Paleogene and perhaps the end of the apatemyid lineage in North America.

AbstractLarval characterizations for the genera of North American Brachycentridae are revised and two new genera created, bringing to five the total number now recognized on this continent. Previous concepts of larval morphology inMicrasemaare emended. Discovery of the larval stage ofBrachycentrus(Amiocentrus)aspilusRoss necessitates elevation of this subgenus to generic status. Association of larvae with the two North American species placed inOligoplectrumnecessitates removal of one,O.dimicki(Milne), toMicrasema. Discovery of all stages of a new species on Mount Hood, Oregon, necessitates creation of a new genus. A provisional larval key to the genera of the North American Brachycentridae is proposed and the phylogenetic relationships of the genera are discussed. Validity of the Asian genusOligoplectrodesis questioned.

A declined four-branched graptoloid is referred to a new species of Allograptus, a genus of the family Sinograptidae described from the uppermost Lower Ordovician of China. This new Canadian species has been discovered from the upper Lévis Formation at Lévis, Québec, and is the first representative of Allograptus in North America. A description of A. canadensis n. sp. is presented with a discussion on its possible significance for international stratigraphic correlation.

A new genus and a new species of acanthocephalan are described from the numbat Myrmecobius fasciatus, a termite-eating marsupial from south-western Australia. Multisentis myrmecobius belongs to the family Oligacanthorhynchidae and a key to the genera of this family is given. The life cycle is presumed to involve termites as the intermediate host. The definitive host-parasite relationship is assumed to have evolved since the origins of M. fasciatus from ancestral marsupial forms before the late Miocene.

A new species of teuthid squid, Teudopsis cadominensis, is described from the Toarcian (Lower Jurassic) Poker Chip Shale of the Fernie Formation in central-western Alberta. Fossil squids are rare in the Mesozoic of North America; this species is the first record of the family Palaeololiginidae in North America and the first member of the suborder Mesoteuthina in the Jurassic of North America.

A new species of Orthoptera,Parapleurites morrisonensis, is described from the upper Jurassic Morrison Formation of Colorado, USA. This is the first insect described from the Morrison Formation and the first orthopteran described from the Jurassic of North America. No other members of the family Locustopsidae have been described in North America previously, and the other species ofParapleuritesare only known from Siberia. The lack of Jurassic Orthoptera in North America is likely due to a combination of taphonomic variables and collector bias. The discovery ofParapleurites morrisonensisand the potential for finding other Jurassic Orthoptera are important to understanding the evolution of this diverse and widely distributed group.

The family Hypoxidaceae is mainly distributed in the southern hemisphere of the Old World and in the North America (Sanchez-Ken 2010), with about 200 species belonging to 11 genera (Sanchez-Ken 2010, Liu et al. 2012, Snijman & Kocyan 2013, Odyuo et al. 2016). The genus Curculigo Gaertner (1788: 63) includes 17 species and 4 varieties (Govaerts 2016). It is characterized by its pseudopetiolate leaves, subterranean beaked ovaries, indehiscent fruits and strophiolate seeds (Zimudzi 1994). The first detailed taxonomic treatment of Indian Curculigo was published by Baker (1878), who recorded 7 species and 3 varieties from British India. Hooker (1892) recognized five species from British India and grouped them into two sections, namely C. sect. Curculigo and C. sect. Molineria Colla (1826: 331). Karthikeyan et al. (1989: 82) listed five species of Curculigo from India. However, Curculigo maharashtrensis Almeida & Yadav (2009: 401) and C. savantwadiensis Almeida & Yadav (2009: 402) have been recently described from Western Ghats of India. Hence, the total number of Indian species of Curculigo is now eight.
