AbstractAcanthomola pubescens, a new genus and species of Heptageniidae (Ephemeroptera), is described from larvae collected in Saskatchewan and Alberta. Acanthomola superficially resembles Bleptus, Epeorus, and Raptoheptagenia, but differs from these genera, and all other heptageniids, in the structure of the mandibles and maxillae. The molar area of the mandible is greatly reduced and bears only a few stout spines. The crown of the maxillary galea-lacinia is rounded and lacks setae near the apex. The apical segment of the maxillary palpus is long, slender, and bare. Generic and specific descriptions of the larva of A. pubescens, gen. nov., sp. no v., are given, along with biological notes. Acanthomola appears to be a very primitive heptageniid, related to Bleptus, Epeorus, and Ironodes. It is probably most closely related to Spinadis.

Lithological Unit

Although mammals of Paleocene age are well known from Alberta, their record is largely restricted to one lithological unit, the Paskapoo Formation (a record that includes mammals from the Cochrane area erroneously attributed to the Porcupine Hills Formation). We report here the first occurrence of Paleocene mammals from the Porcupine Hills Formation at exposures near the western edge of the city of Calgary. The assemblage, termed the Bearspaw local fauna, documents a diversity of multituberculate and eutherian mammals, including new species of the pentacodontid Aphronorus bearspawensis sp. nov., the mixodectid Eudaemonema bohachae sp. nov., the hyopsodontid Promioclaenus thnetus sp. nov., and a new genus and species of multituberculate (Alopocosmodon hadrus gen. et sp. nov.) tentatively referred to the Microcosmodontidae. The Bearspaw local fauna also details the first Canadian occurrences of several taxa, including Ptilodus wyomingensis, Aphronorus fraudator, Bryanictis microlestes, Elpidophorus minor, and possibly Goniacodon. Preliminary biostratigraphic analyses suggest that the Bearspaw local fauna is middle Torrejonian (To2) in age, correlating most closely with near-coeval Gidley Quarry of Montana and Rock Bench Quarry of Wyoming. In addition to improving the depauperate record of Torrejonian mammals in western Canada, the new fauna is important in documenting a mammal assemblage from a lithological unit that is thought to have been deposited in semi-arid conditions, rather than the wetter and more humid conditions of the Paskapoo Formation. Further, the Bearspaw localities, along with several other recently discovered localities in the Calgary and Cochrane areas, closely bracket the 27n–26r chron boundary and as such will be important in detailing the Torrejonian–Tiffanian transition in western Canada.

Late Paleocene

A new genus and species of erinaceid lipotyphlan (Mammalia, Insectivora) from the late Paleocene of western Canada is described. Oncocherus krishtalkai gen. et sp. nov. is known from three late Tiffanian localities in central Alberta and southeastern Saskatchewan and is but one of several erinaceomorph and soricomorph taxa known from the Late Paleocene of western Canada. Oncocherus possesses apomorphies that link it to other primitive erinaceids (e.g., enlarged upper and lower fourth premolars, lower molars markedly decreasing in size from m1-m3, talonid basins V-shaped), yet its affinity with any of the recognized erinaceid subfamilies is uncertain. Although Oncocherus is phenetically, and probably phylogenetically, closest to Litolestes Jepsen, the genus is clearly distinguished from Litolestes and other erinaceid taxa by its proportionately larger and more inflated premolars and lower crowned molars, features that were likely adaptations for durophagy. Oncocherus joins a number of endemic mammalian taxa that were apparently confined to more northerly latitudes of the Western Interior of North America during the Late Paleocene.

The paper reported one new genus and six new species from Yunnan, China. The new genus, Neoteratura gen. nov. is similar to the genus Alloteratura Hebard, 1922, but differs from the latter by: apical segment of maxillary palpus slightly shorter than subapical one; humeral sinus indistinct; tegmina shorter, not reaching or slightly surpassing apex of abdomen, but longer than hind wings; male genitalia sclerotized, simple; cercus divided into two branches, or with branches. It resembles the genus Borneratura Gorochov, 2008, but differs from the latter by: tegmina and hind wings shorter; male genitalia sclerotized, cercus with branches.

A new genus and species of the pselaphine tribe Tyrini, Klimaszewskia punctata gen. et sp. nov., is described and illustrated from Java, Indonesia. Klimaszewskia gen. nov. differs from all other genera of Tyrini primarily by the long, extended maxillary palpus having the fourth palpomere that is mesally expanded near the base, and has an elongate and narrowed apical region, combined with the presence of an antebasal sulcus of the pronotum, and the long first visible tergite. A single female with much larger body size from Nepal, representing a second species of the new genus, is briefly characterized but left unnamed.

New Genus And Species

AbstractA new genus and species of Heptageniidae (Ephemeroptera) is based on a series of nymphs and reared female adults from the Saskatchewan River, Saskatchewan. Descriptions of female and nymphal Macdunnoa nipawinia n. gen., n. sp., of the subfamily Heptageniinae, are given along with notes on the biology. The genus has no close North American relatives, but is allied to heptageniid genera from southeast Asia.

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.

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.
