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.

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.

A new genus is proposed to accommodate an unusual new species, Gonatothrix carinata, of the mite family Macrochelidae phoretic on the scarab beeetle Phanaeus pyrois. The new genus is distinguished by strong opisthosomatic hypertrichy, a strongly narrowed opisthonotal component of the dorsal shield, singular sternal shield ornamentation, and the presence of eight setae on genu III.

Mite Genus

A new monotypic mite genus of the family Laelapidae, Persicolaelaps gen. nov., is described to accommodate a new species, P. hallidayi sp. nov., on the basis of adult female specimens collected from decaying wood, soil and litter in northern Iran, Golestan and Mazandaran provinces, respectively. The new genus can be distinguished from other members of the family by a combination of morphological attributes, some of which are unique or rarely observed in laelapids, such as (1) a series of small subrectangular sclerites flanking dorsally coxae I and gnathosomal base and adjoining podal plates anterolaterally, which are extending from and fused with sternal shield between coxae I and II; (2) an epigynal shield, so broad as to reach or even overlap acetabula III–IV, posteriorly axe-shaped; (3) metasternal setae absent; (4) a typical anal shield, though capturing pair of opisthogastric setae JV3; (5) gnathotectum triangular and acuminate; (6) the presence of six setae on trochanter IV; (7) genu IV with two ventral setae (occasional in Laelapidae); (8) internal malae with a series of thick, elongate filaments.

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.

AbstractA new genus and new species of Nymphidae (Neuroptera) is described from the Ypresian Okanagan Highlands locality of Falkland, British Columbia, Canada: Epinesydrion falklandensisnew genus, new species. This is only the fourth known Cenozoic adult specimen, and all others are less complete. It is the second specimen from the Okanagan Highlands. Currently Nymphidae has two recognised subfamilies. All Cenozoic fossils are confident members of the Nymphinae, but the subfamily assignments of almost all Mesozoic genera are problematic. The Late Cretaceous Dactylomyius is the only genus that might belong to Myiodactylinae. The rest may belong to the undefined stem groups of the family or to the Nymphinae, with varying levels of probability. Mesonymphes sibirica is transferred to Nymphites Haase: N. sibiricus (Ponomarenko), new combination; Sialium minor to Spilonymphes Shi, Winterton, and Ren: Spilonymphes minor (Shi, Winterton, and Ren), new combination; “Mesonymphes” apicalis does not belong to Mesonymphes Carpenter and may not even belong to the Nymphidae. The fossil record of the family occurs across much of the globe, but today they are restricted to Australia, New Guinea, and possibly the Philippines. Modern Nymphinae is only found in Australia. This may result from a requirement of frost-free climates, which were more widespread in the past.

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.

AbstractThe definition of the family Evaniidae is revised and Cretevaniidae are synonymised with Evaniidae based on evidence derived from recently described Mesozoic taxa and a new genus and species, Lebanevania azari, described here from Lebanese amber. A fore leg with a long trochanter and a 12-segmented antenna are autapomorphies of the new genus. A large, high and wide head and a high and short mesosoma are derived characters shared with other Evaniidae. The new genus also has complete fore wing venation and lacks a tubular petiole, which are ground plan features of the Evanioidea. A cladistic analysis of fossil and extant members of the superfamily Evanioidea and notes on fossil taxa are presented.

A fragmentary specimen of pterosaur originally assigned to the genus Pterodaustro Bonaparte, 1970 is reassessed. The presence of a sagittal dorsal cranial crest on a fragment of nasopreorbital arcade with linear vertical trabeculae and the occurrence of alveolar protuberances on the os dentale indicate the new specimen has similarities with crested pterodactyloid pterosaurs of the family Ctenochasmatidae, and with members of the Dsungaripteridae. The presence of alveolar protuberances allows us to assign the specimen to the Dsungaripteridae. It forms the basis of a new genus and species, Domeykodactylus ceciliae.

Dental Ontogeny

An exceptionally well-preserved silicified bivalve from the Upper Permian of Texas is described and assigned to a new genus and species,Cassiavellia galtarae, placed in the family Bakevelliidae. The species represents one of the earliest and best characterized unequivocal occurrences of the multivincular ligament in the superfamily Pterioidea. The silicified material provides a wealth of information on the morphology of inadequately known Paleozoic pterioideans, including hitherto undescribed aspects of the larval shell, auricular sulcus, muscle scars, and dental ontogeny. The discovery of the condyle-fossa complex on the anteroventral shell margin, a feature previously undescibed in Bivalvia, raises the question of the homology and taxonomic significance of the problematic subumbonal ridge-like structures in Pterioidea. In life,C. galtaraewas probably an epifaunal right-pleurothetic bivalve, byssally attached to hard or raised flexible substrata. In addition toC. galtarae, another new species,C. nadkevnae, is placed inCassiavellia.
