The hydromedusa Geomackiea zephyrolata gen. nov., sp. nov. is described and illustrated. It has been placed in the subfamily Protiarinae of the family Pandeidae on the basis of its stomach and gonad morphology and the four large perradial tentacles with conical basal bulbs. A new genus has been erected because the medusa is supplied with four broad interradial bulbs, each rimmed by up to eight closely packed solid tentaculae. A total of 29 specimens with bell heights of 0.9–3.5 mm have been collected in the plankton of Saanich Inlet, British Columbia, and Friday Harbor, Washington, between 1978 and 1981. Juvenile as well as adult specimens are described and the cnidome, gametes, seasonal and vertical distributions, and taxonomic affinities within the family Pandeidae are discussed.

Both the genus Shastasaurus and the family Shastasauridae have long been hard to define due to the fragmentary nature of the type specimens. Consequently, recent interpretations of the genus have been based almost entirely on Shastasaurus neoscapularis from the Late Triassic Pardonet Formation of British Columbia. Two new specimens of this taxon, from Pink Mountain, British Columbia, demonstrate that it does not belong in the genus Shastasaurus. This paper describes the new specimens, and refers the species to Metashastasaurus gen nov. Post-cranially, the skeleton of Metashastasaurus resembles that of shastasaurids, differing primarily only in the shape of the scapula and fibula. However, the skull has a unique combination of characters, including large diamond-shaped frontals that enter the supratemporal fenestrae, and very narrow posterior extensions of the nasals, which contact the postfrontals. It also differs from the skull of Shastasaurus in the presence of both a parietal ridge and postparietal shelf. This is a combination of derived characters previously known only in Jurassic forms. The front limb has four proximal carpals and four digits, indicating that previous reconstructions were based on incomplete material. Shastasaurus pacificus Merriam 1895, the type species of the genus Shastasaurus, must be considered a nomen dubium, making the genus Shastasaurus invalid. Until this problem is clarified, the use of the generic name Shastasaurus should be restricted to Merriam's type specimens, of which only Shastasaurus alexandrae and Shastasaurus osmonti are based on adequate material.

The significant taxonomic characters of the millipede family Striariidae Bollman, 1888 are discussed. The monotypic genus Vaferaria Causey, 1958 is synonymized under Amplaria Chamberlin, 1941, giving the new combination Amplaria imberbis (Loomis, 1936). The genera Striaria Bollman, 1888 and Amplaria are assigned to the subfamily Striariinae. A new subfamily, Trisariinae, is established that presently includes only Trisaria new genus, with three new species: Trisaria rex, T. olympia and T. washingtonensis. The new subfamily, genus, and species are endemic to western Washington state, USA.

AbstractThree new species of Pipunculidae (Diptera) are described (one named), from the early Eocene (Ypresian) Okanagan Highlands of British Columbia, Canada and Washington State, United States of America: Metanephrocerus belgardeaenew species from Republic, Washington; and Pipunculidae species A and Pipunculinae species A from Quilchena, British Columbia. We re-describe the late Eocene (Priabonian) species Protonephrocerus florissantius Carpenter and Hull from Florissant, Colorado, United States of America, and assign it to a new genus proposed here, Priabonanew genus. Pipunculinae species A is the oldest known member of the family whose wing lacks a separated M2 vein; previously this had been known in species only as old as Miocene Dominican amber. This is a presumably derived character state that is predominant in modern species. Molecular analysis indicates an origin of the Pipunculidae in the Maastrichtian; the morphological and taxonomic diversity seen here in the Ypresian is consistent with an early radiation of the family. This is concordant with the radiation of Auchenorrhyncha, upon which they mostly prey, which is in turn associated with the early Paleogene diversification of angiosperm-dominated forests recovering from the K-Pg extinction event.

Six new species of the extinct family Dinopanorpidae (Mecoptera) are described in the new genus Dinokanaga gen. nov. from five Early (and early Middle?) Eocene Okanagan Highlands localities in British Columbia and Washington State. These are Dinokanaga hillsi sp. nov., D. wilsoni sp. nov., D. dowsonae sp. nov., D. andersoni sp. nov., D. sternbergi sp. nov., and D. webbi sp. nov. The family Dinopanorpidae is previously known only from a hind wing of Dinopanorpa megarche Cockerell, and an undescribed species of Dinopanorpa, both from the Paleogene of Primorye (Maritime Province) in Pacific coastal far-eastern Russia. The family includes mostly large species, with forewings up to 43 mm in length. Dinopanorpidae is particularly distinguished by a long R1 vein in both the fore- and hind wings, extending almost to the wing apex and bending posteriad distally. Their wings are mostly dark with light bands and spots; have many to extremely dense crossveins; and an expanded costal space in the basal quarter of the forewing, which is more developed in larger species. The rostrum is extended; the medigynium is without tongue-shaped structures.

A single specimen of decapod crustacean, preserved in ventral view and compressed, represents a new genus and species of eryonid lobster, Wrangelleryon perates. The discovery in Lower Jurassic (Hettangian) sediments of the Sandilands Formation in British Columbia represents the first occurrence of Eryonidae in North America and reinforces a global distribution of the family in the Jurassic. The occurrence in British Columbia on the Wrangellia terrane supports the lower latitude setting in which the species lived.

One new genus and two new species of fossil frog crabs from the Eocene to Oligocene deposits of Washington State (USA) and Vancouver Island (British Columbia, Canada) of the north-eastern Pacific are described, based upon several well- preserved specimens. The studied specimens are herein described as Amphoranina blandi n. gen., n. sp. and A. multispinata n. gen, n. sp. (Raninidae De Haan, 1839) respectively. Amphoranina n. gen. appears to be endemic to the middle to upper Paleogene of the northeastern Pacific.

AbstractMicroberotha macculloughigen. nov. and sp. nov. from Early Eocene Okanagan Highlands amber of Hat Creek, British Columbia, Canada, is described. This new genus and species represents one of the smallest members of the family Berothidae and the first occurrence of the family in the New World Tertiary. The systematic position of the genus Microberotha within the family is rather unclear, but the structure of the male genitalia indicates a close association with the subfamily Cyrenoberothinae. Stratigraphy and palaeoenvironment of the Hat Creek locality are briefly discussed.

Eighty-three fossil crabs, belonging to a new genus and species, and interpreted to be mainly exuviae, were collected from concretions within the Spray Formation at Shelter Point, Vancouver Island, British Columbia. They are assigned to the family Carcineretidae and named Longusorbis cuniculosus. The excellent preservation of the fossil crabs is a consequence of being buried in their own dwelling burrows in the intertidal zone, and subsequent formation of concretions around the specimens very early during diagenesis. Several species of mollusc occur with the crabs, and the faunal assemblage is assigned to the Pachydiscus suciaensis Zone of late Campanian to early Maestrichtian age. The small part of the Spray Formation exposed at Shelter Point contains six units of detrital sediment deposited in environments inferred to range from shallow neritic to supratidal.

Mite Genus

A new genus and species of the Anisitsiellidae, collected from a seepage area in central British Columbia, is described. The genus is noteworthy because, like Bandakia, it has a complete, unsculptured dorsal shield and the fourth tarsi bear well-developed terminal claws, although the appearance of a gland opening in coxa I is unique. The possession of a simple palp in this mamersopsoid genus further serves to justify the inclusion of the genera formerly belonging to the family Mamersopsidae within the family Anisitsiellidae.
