Description and figures are presented for the following species and subspecies, which the writer considers should constitute the genus Streptocara: S. crassicauda crassicauda (Creplin, 1829), S. crassicauda longispiculata n. subsp., S. californica (Gedoelst, 1919), S. formosensis Sugimoto, 1930, S. incognita n. sp., and S. recta (Linstow, 1879). Host-lists and data on prevalence in birds, mainly waterfowl, from British Columbia, Canada, are given for these species and Paracuaria tridentata (Linstow, 1877). Yamaguti's 1961 list of species of Streptocara is examined critically; some of the modifications suggested in the literature since 1961 are accepted, and the following changes proposed: S. cirrohamata (Linstow, 1888) to Ingliseria cirrohamata (Linstow, 1888) new genus, new combination; S. triaenucha (Wright, 1879) to Synhimantus (D.) triaenucha (Wright, 1879) n. comb. (syn. S. (D.) canadensis Mawson, 1956); and S. somateriae Ryzhikov, 1960 to synonymy with S. formosensis Sugimoto, 1930.

A. bendelli n. sp. differs from the others of the genus in that its dentate cephalic quadrants join laterally producing a bipartite rather than quadripartite appearance. It can be recognized also by its combination of large dentiform processes, long vestibule, short glandular oesophagus, and 9–14 pairs of preanal papillae; no other species parasitizes an obligate terrestrial host. The following species composition is proposed for Ancyracanthopsis Diesing, 1861: A. bilabiata (Molin, 1860) A. coronata (Molin, 1860); A. madagascariensis Kung, 1948; A. petrovi Guschanskaya, 1950; (?)A. parvialata (Belopolskaya, 1953); A. gallinulae (Wang, 1966) n. comb.; and A. bendelli n. sp. It is concluded that A. quadripartita (Clapham, 1945) and A. schikhobalovi Guschanskaya, 1950 are synonyms of A. coronata, and that Skrjabinobronema sinica Wang, 1966 is a synonym of A. madagascariensis. Specimens of Sciadiocara umbellifera (Molin, I860) (Syn: S. legendrei Petter, 1967) from British Columbia possess minute serrations along the posterior edges of the cephalic lappets. Viktorocara limosae Mawson, 1968 is considered a synonym of V. limosae Daiya, 1966. Stellocaronema Gilbert, 1930 should contain S. skrjabini Gilbert, 1930 (Syn: S, glareolae Mawson, 1968) and S. fausti (Li, 1934) n. comb, (Syn: Stellocaronema buckleyi Sarwar, 1956); S, charadrii Mawson, 1968 probably represents a new genus. New records are A. coronata from Actitis macularia and Seiurus noveboracensis in British Columbia and from Cassidix mexicanus in Mexico; V. limosae from Erolia alpina; and S. skrjabini from E. alpina, Ereunetes mauri, and Crocethia alba in British Columbia.

A new fauna of fossil marine reptiles is described from the Late Cretaceous Nanaimo Group of Vancouver Island. The fossils are from the Haslam and Pender formations (upper Santonian) near Courtenay, British Columbia, and include elasmosaurid plesiosaurs, turtles, and mosasaurs. This is only the second fauna of Late Cretaceous marine reptiles known from the Pacific Coast, the other being from the Moreno Formation of California (Maastrichtian). The new Nanaimo Group fossils are some 15 million years older than those from the Moreno Formation. However, like the California fauna, there are no polycotylid plesiosaurs, and one of the mosasaurs is a new genus. This reinforces the provinciality of the Pacific faunas and their isolation from contemporaneous faunas in the Western Interior Seaway.

A new form-genus, Mycopappus, is recognized for fungi producing multicellular, epiphyllous, splash-dispersed propagules previously described under the names Cercosporella alni Dearness and Bartholomew and C. aceris Dearness and Batholomew. Mycopappus alni comb. nov. occurs on Alnus rubra Bong, or A. sinuata (Regel) Rydb. along the Pacific coast from the Alaskan panhandle to Oregon. Mycopappus aceris comb. nov. on Acer macrophyllum Pursh occurs from southern British Columbia to Oregon. Anguillospora vermiformis (Davis) comb. nov. on Alnus rugosa (Du Roi) Spreng. in Wisconsin and A. coryli sp. nov. on Corylus americana Walt, and C. cornuta Marsh, in Wisconsin have been confused with Mycopappus alni. All four species are leaf pathogens.

Chrysopetalids annelids have been little studied in the Tropical Eastern Pacific (TEP), with only 24 species recorded in the region. Most records are from northwestern Mexico and Costa Rica, leaving many sites along the Tropical Pacific coast of America unexplored. Furthermore, there are species recorded and described from the region with problems in their status, including questionable records, modest illustrations or descriptions, and lost type material. This paper aims to improve the knowledge of this family in the TEP. Almost 290 specimens were revised, provided from five scientific collections, covering 51 sites along the TEP and nearby. Two subfamilies: Calamyzinae and Chrysopetalinae, nine genera and 20 species were determined. Of these, ten species have been previously recorded, three are indeterminable and seven are new species: Paleanotus karlyae n. sp., Arichlidon mucropaleum n. sp., Bhawania bastidai n. sp., Chrysopetalum mexicanum n. sp., C. tovarae n. sp. A new genus is proposed, Bhawatsonia n. gen. which includes two new species, B. fusa n. sp. as its type species, B. nenoae n. sp. and, the new combination and neotype of B. purpurea n. comb. An updated and revised checklist of all chrysopetalids species recorded in the region is included, currently composed of 16 genera, 30 species, and four morphospecies.

The small lacewing genus Apertochrysa comprises species from Africa, Asia and Australia. All lack a tignum, but otherwise resemble distantly related genera. We show that Apertochrysa does not form a monophyletic clade, based on analyses of molecular sequence data and morphological traits such as the presence and shape of the male gonapsis, wing venation, and larval setae. Apertochrysa kichijoi forms a clade with Eremochrysa, Suarius and Chrysemosa, whereas A. albolineatoides belongs to a clade that includes Cunctochrysa. Apertochrysa albolineatoides should become a new combination as Cunctochrysa albolineatoides, while A. kichijoi will have to be transferred to a new genus. The Australian A. edwardsi, the African A. eurydera and the type species of the genus Apertochrysa, A. umbrosa, join the large Pseudomallada group. Relationships of A. umbrosa are less certain, because for it we could amplify only one of the three nuclear genes used in the overall analysis. However, in all morphological traits tested, that species strongly resembles A. edwardsi and A. eurydera and thus is very likely just another exceptional Pseudomallada lacking a tignum. The fate of the genus name Apertochrysa depends on additional molecular and morphological analyses of A. umbrosa.

Earthquakes in the past few thousand years have left signs of land-level change, tsunamis, and shaking along the Pacific coast at the Cascadia subduction zone. Sudden lowering of land accounts for many of the buried marsh and forest soils at estuaries between southern British Columbia and northern California. Sand layers on some of these soils imply that tsunamis were triggered by some of the events that lowered the land. Liquefaction features show that inland shaking accompanied sudden coastal subsidence at the Washington-Oregon border about 300 years ago. The combined evidence for subsidence, tsunamis, and shaking shows that earthquakes of magnitude 8 or larger have occurred on the boundary between the overriding North America plate and the downgoing Juan de Fuca and Gorda plates. Intervals between the earthquakes are poorly known because of uncertainties about the number and ages of the earthquakes. Current estimates for individual intervals at specific coastal sites range from a few centuries to about one thousand years.

AbstractThe crustose lichen genus Mycoblastus in the Northern Hemisphere includes eight recognized species sharing large, simple ascospores produced 1–2 per ascus in strongly pigmented biatorine apothecia. The monophyly of Mycoblastus and the relationship of its various species to Tephromelataceae have never been studied in detail. Data from ITS rDNA and the genes coding for translation elongation factor 1-α and DNA replication licensing factor mini-chromosome maintenance complex 7 support the distinctness of Mycoblastus s. str. from the core of the Tephromelataceae, but recover M. fucatus and an undescribed Asian species as strongly supported within the latter group. We propose accommodating these two species in a new genus, Violella, which is characterized by its brownish inner ascospore walls, Fucatus-violet hymenial pigment granules and secondary chemistry, and discuss the position of Violella relative to Calvitimela and Tephromela. We describe the new species Violella wangii T. Sprib. & Goffinet to accommodate a new species with roccellic acid from Bhutan, China, India and the Russian Far East. We also exclude Mycoblastus indicus Awasthi & Agarwal from the genus Mycoblastus and propose for it the new combination Malmidea indica (Awasthi & Agarwal) Hafellner & T. Sprib.

AbstractNeotherevella n.gen. is proposed as a replacement for Neothereva Kröber sensu Lyneborg (1976). Neothereva Kröber, 1912, is placed in new synonymy with Thereva Latreille, 1796, as the consequence of an overlooked designation of a type-species for Neothereva Kröber, 1912, by Kröber (1935). Neotherevella is fully described. Five specific names are placed in new combination with Neotherevella, which is known from Namibia, Mauritania, Algeria, Sudan, Egypt, Israel, Uzbechistan and Mongolia. It is demonstrated that two species described in combination with Neothereva by Zaitzev (1970) do not belong to Neotherevella.
