Glandular Oesophagus

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.

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.

Betapista dekkerae, new genus and new species, is described. The generic diagnoses for Laphania and Scionides are improved after inspection of the holotypes of the type species. Eupolymnia heterobranchia (syn., E. crescentis) is redescribed. Additions to the descriptions, based on study of type material, are made for Laphania boecki (new record, Northeast Pacific), Neoamphitrite robusta (syn., Scionides dux), Neoleprea californica and N. spiralis, Pista brevibrunchiata (new record, British Columbia [B.C.], Washington [WA], Japan) and P. fratrella, and Polycirrus californicus (new record, B.C., WA, syn., P. perplexus). Other additions to the descriptions are provided for Amaeana occidentalis (new record, B.C.) and Pista cristata. Two further Pista species (one from the Skagerrak) and five Polycirrus species are charcterized but not named. Other new records are Lanassa venusta venusta (B.C.), Lysilla loveni, and Neoleprea japonica (the two latter for Northeast Pacific). Lysilla pacifica, Pista fasciata, and P. fratrella are shown not to be members of the fauna of British Columbia and Washington. Presumably, neither is Polycirrus caliendrum. New observations on the types of the Antarctic Polycirrus kerguelensis and Ereutho kerguelensis are noted.Key words: Betapista n.g., Neoleprea, new records, Northeast Pacific, Pista, Polycirrus, Scionides, Terebellidae

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.

Four new shallow water species of the genus Pacifigorgia were found in recent surveys along the Pacific coast of Panama. One of the species was only found in dense patches at two shallow seamount-like localities inside the Coiba National Park, Gulf of Chiriqu . Two other species were patchily distributed at several localities in the Gulf of Chiriqu . A fourth species was widely distributed around the gulfs of Chiriqu and Panama encompassing a broad range of habitats and depths. The new species are described and illustrated in detail with scanning electron micrographs (SEM) of the sclerites, and colour photographs of the colony forms. The suspected occurrence of a particular Pacifigorgia species for this region is confirmed and two other new records are added to the species list. With the new four species, a total of 15 are established for Panama, making 31 species for the eastern Pacific to date.

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.

In the present work was carried out in the intertidal zone of Las Baulas de Guanacaste National Marine Park (PNMB) located on the Pacific coast of Costa Rica.                The main objective was to contribute to knowledge about the invertebrate diversity of the park, one of the richest bioregions on the planet, about which little is known. This study assesses the Order Polycladida Lang, 1884, a cornerstone of this ecosystem and one of the most cosmopolitan and plastic invertebrate taxa in the animal kingdom.                In total, 57 individuals were collected in the rocky intertidal zone of Carbón and Langosta beaches. Nine different species were identified, of which four are new for Costa Rica: Semonia bauliensis n. sp.; Cryptostylochus sesei n. sp.; Paraplanocera angeli n. sp., Prostheceraeus fitae n. sp.; and five new records: Paraplanocera oligoglena (Schmarda, 1859); Marcusia ernesti Hyman, 1953; Enchiridium magec Cuadrado, Moro & Noreña, 2017; Pseudobiceros bajae (Hyman, 1953); and the genus Boninia spp.
