A New Species

Occella impi, a new species of sea poacher, is described from a single specimen captured in the Queen Charlotte Islands, British Columbia. Occella impi differs from other species of Occella in having spinous plates on the breast, the anus nearer the anal fin, and fewer anal rays; also, the numbers of bony body plates are distinctive. A key to the known species of Occella, based primarily on the numbers of bony body plates, is included. The size of the maxillary barbel and number of infralateral plates are shown to be characteristic of the genera Occella and Stellerina.

A New Species

A new species of kathlaniid nematode, Megalobatrachonema waldeni, from the intestine of the northwestern salamander, Ambystoma gracile, in British Columbia is described. The new species is placed in the subgenus Megalobatrachonema (Chabaudgolvania) as it lacks valves in the oesophageal bulb. Megalobatrachonema waldeni differs from the two other members of this subgenus, M. elongatum (Baird, 1958) and M. terdentatum (Linstow, 1890), in having large cervical alae and distinctly separate lips, and in lacking hypodermal lip peduncles and a pseudosucker. Megalobatrachonema waldeni has simpler onchia, smaller spicules, and a more prominent swelling at the base of the oesophageal corpus than M. elongatum, and differs from M. terdentatum by its distinct corpus swelling, more anterior excretory pore, fewer caudal papillae, and longer tail.

A New Species

A new species of colonial athecate hydroid, Rhysia fletcheri, is described from Vancouver Island, British Columbia, Canada, and from Friday Harbor, Washington, U.S.A. Its relationship to Rhysia autumnalis Brinckmann from the Mediterranean and Rhysia halecii (Hickson and Gravely) from the Antarctic and Japan is discussed. Rhysia fletcheri differs from Rhysia autumnalis and Rhysia halecii in the gastrozooid having distinctive cnidocyst clusters on its hypostome and few, thick tentacles. Most of its female gonozooids have no tentacles. Colonies of R. fletcheri are without dactylozooids. The majority of R. fletcheri colonies are found growing on large barnacles or among the hydrorhiza of large thecate hydrozoans. Rhysia fletcheri occurs in relatively sheltered waters of the San Juan Islands and on the exposed rocky coast of southern Vancouver Island.

A New Species

Lampetra macrostoma n.sp., a freshwater parasitic lamprey, is distinguished from related species L. tridentata, L. lethophaga, L. folletti, L. minima, and L. similis by its parasitic habit and very large disc. Other characters distinguishing the species from L. tridentata are its longer prebranchial length, large eye, weakly pigmented velar tentacles, and its ability to remain in freshwater. The recently metamorphosed form readily survives in freshwater and probably is non-anadromous even though it can survive in salt water. The new species has been discovered in two lakes on Vancouver Island, British Columbia, Canada, where it attacks large numbers of resident salmonids. Because of its ability to survive and feed in freshwater, it poses a definite threat to freshwater fishes.Key words: lamprey, new species, non-anadromous lamprey, salmonid parasitism

A New Species

A new species of stem actinopterygian, Helmolepis cyphognatus sp. nov., is reported from the Lower Triassic Sulphur Mountain Formation of western Canada (probably Smithian). This taxon differs from the only other known Early Triassic platysiagid, H. gracilis from the Lower Triassic Wordie Creek Formation of East Greenland (Griesbachian), in counts of branchiostegal rays, shape of the maxilla, shape (and possibly counts) of extrascapulars, and the size ratio of major opercular bones. In spite of their overall unfavorable preservation, the numerous available specimens amend our knowledge of the little known genus Helmolepis considerably: it has become evident that the morphology of Helmolepis cyphognatus sp. nov. comes closest to Platysiagum minus (Middle Triassic Besano Formation of central Europe). This study suggests placement of the two genera in the family Platysiagidae. Investigation of this new species also shows certain features of the cheek and the caudal fin are more primitive than previously believed, whereas the snout region is probably derived but of yet uncertain affinities in Helmolepis.

AbstractArchaeochrysa sanikwanew species (Neuroptera: Chrysopidae: Nothochrysinae) is described from early Eocene (Ypresian) Okanagan Highlands shale at Driftwood Canyon, British Columbia, Canada. The evolutionary trends of three chrysopid wing venation characters (the shape of the intramedian cell, the position of the crossvein 2m-cu, and the development of the pseudocubitus) are analysed. The forewing venation of this species is very plesiomorphic compared with the vast majority species of Nothochrysinae, both fossil and extant.

Cucullanellus kanabus sp. nov., parasitic in the intestine of the embiotocid fish, Cymatogaster aggregata Gibbons from Departure Bay, British Columbia is described and illustrated. The main features distinguishing C. kanabus from previously described species in the genus are the arrangement of the caudal papillae in males, the general body shape and various measurements. The species considered referable to Cucullanellus Törnquist 1931 are listed.

A new porcellanid crab, Petrolisthes landsendi Garassino & Nyborg n. sp., from the Upper Cretaceous (upper Santonian) Nanaimo Group of Vancouver Island (British Columbia, Canada) is herein described. Petrolisthes landsendi Garassino & Nyborg n. sp. represents the oldest species of Petrolisthes Stimpson, 1858 and is the first species from the northeastern Pacific, thus expanding the stratigraphical age and geographical range of the genus.

AbstractA well-preserved fauna of largely articulated trilobites is described from three new localities close to one another in the Bull River Valley, southeastern British Columbia. All the trilobites from these localities are from the lower or middle part of the Wujiajiania lyndasmithae Subzone of the Elvinia Zone, lower Jiangshanian, in the McKay Group. Two new species are proposed with types from these localities: Aciculolenus askewi and Cliffia nicoleae. The trilobite (and agnostid) fauna from these localities includes at least 20 species: Aciculolenus askewi n. sp., Agnostotes orientalis (Kobayashi, 1935), Cernuolimbus ludvigseni Chatterton and Gibb, 2016, Cliffia nicoleae n. sp., Elvinia roemeri (Shumard, 1861), Grandagnostus? species 1 of Chatterton and Gibb, 2016, Eugonocare? phillipi Chatterton and Gibb, 2016, Eugonocare? sp. A, Housia vacuna (Walcott, 1912), Irvingella convexa (Kobayashi, 1935), Irvingella flohri Resser, 1942, Irvingella species B Chatterton and Gibb, 2016, Olenaspella chrisnewi Chatterton and Gibb, 2016, Proceratopyge canadensis (Chatterton and Ludvigsen, 1998), Proceratopyge rectispinata (Troedsson, 1937), Pseudagnostus cf. P. josepha (Hall, 1863), Pseudagnostus securiger (Lake, 1906), Pseudeugonocare bispinatum (Kobayashi, 1962), Pterocephalia sp., and Wujiajiania lyndasmithae Chatterton and Gibb, 2016. Pseudagnostus securiger, a widespread early Jiangshanian species, has not been previously recorded from southeastern British Columbia. Non-trilobite fossils collected from these localities include brachiopods, rare trace fossils, a complete silica sponge (Hyalospongea), and a dendroid graptolite. The faunas from these localities are more diverse and better preserved than those from other previously documented localities of the same age in the region.Additional specimens of a rare species, found by amateur collectors in previously documented localities of slightly younger age (upper part of Wujiajiania lyndasmithae Subzone) in the same region, are documented. These new specimens, when combined with an earlier discovered specimen, provide adequate type material to propose a new species of Labiostria, L. gibbae, which may be useful for biostratigraphy.UUID:http://zoobank.org/89551eac-b3af-4b2b-8ef3-7c2e106a560d
