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.

The Family

The family Nomoclastidae is revised and, based on a cladistic analysis, Callcosma Roewer, 1932 is transferred to the family from Cranaidae. The monotypic genus Napostygnus Roewer, 1929, hitherto considered incertae sedis, is also assigned to Nomoclastidae. Zygopachylus Chamberlin, 1925 and Poassa Roewer, 1943 are synonymised under Quindina Roewer, 1914, consequently creating the new combinations Quindina limbata (Roewer, 1914) and Quindina albomarginis (Chamberlin, 1925). The new combination Quindina marginata (Roewer, 1963), comb. nov. is proposed, as the type-species of Deriacrus, D. simoni Roewer, 1932, is not congeneric with Deriacrus marginatus Roewer, 1963 and has the synapomorphies of Quindina, such as a row of large rounded tubercles on the lateral margin and enlarged tubercles on the dorsal scutum. A new genus and species are proposed, Kichua rheimsae, sp. nov., from Ecuador (type locality: Ecuador, Napo, Cantón Quijos, Parroquira Cozanga, Yanayacu Research Station). In addition, seven new species are herein described: Callcosma abrapatricia, sp. nov. (type locality: Peru, Moyobamba, Abra Patricia Private Conservation Area); Callcosma cofan, sp. nov. (type locality: Ecuador, Sucumbíos, Cabanas Cuyabeno); Callcosma barasana, sp. nov. (type locality: Colombia, Vaupés, Tararira, Estacción Biológica da Caparu); Quindina albiocularia, sp. nov. (type locality: Panama, Coclé, Valle de Antón); Quindina burbayar, sp. nov. (type locality: Panama, Reserva Natural Privada Burbayar); Quindina kuna, sp. nov. (type locality: Panama, Darién, Chucantí); and Quindina morae, sp. nov. (type locality: Panama, Gamboa, Sendero del Oleoducto).

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.

AbstractIn contrast to almost all other invertebrate phyla that constructed biomineralized skeletons during the “Cambrian explosion” and maintained them during the entire fossil record, ascidian tunicates evolved this protective and stabilizing advantage only during the Permian, although soft-bodied representatives of this subphylum made their first appearance already in the early Cambrian. It remains enigmatic why these compound calcareous skeletons persisted only until the Late Triassic, subsequently followed by less-rigid internal skeletons from the Lower Jurassic onwards, which consist of scattered isolated spicules only. In addition to recently described aragonitic ascidian exoskeletons from the Permian and Triassic, new discoveries of similar, but colonial ascidian compound endoskeletons in the lower Carnian exhibit a short-living branch of this group, which moreover contain the first indubitable calcareous spicules. The latter are embedded in the solid endoskeleton, which is composed of polygonal aragonitic plates with smooth outer and zigzag lined inner boundaries. They consist of irregular, parallel (orthogonal), or fan-shaped (clinogonal) arrangements of acicular aragonite crystals. The following taxa are described as new: order Cassianomorpha new order with the family Cassianosomidae new family and the genus Toscanisoma new genus with the species T. multipartitum new species and T. triplicatum new species.UUID: http://zoobank.org/03555353-cdab-42e8-8e99-9bfce15fa249

Stratigraphic Range

Silurian ramphoprionid polychaete annelids, represented by their jaws (scolecodonts), are described from extensive collections from Gotland, Sweden. The family Ramphoprionidae, monotypic at its original description, is sub-divided into four genera; Protarabellites Stauffer, 1933; Ramphoprion Kielan-Jaworowska, 1962; “Pararamphoprion” Männil and Zaslavskaya, 1985; and Megaramphoprion new genus. Identified species include “P.” cf. nordicus Männil and Zaslavskaya, 1985; P. rectangularis new species; P. staufferi new species; P. triangularis new species; and two Protarabellites species left in open nomenclature. Ramphoprion is represented by one new highly plastic species, R. gotlandensis, housing five distinguishable morphotypes showing gradual evolution. Megaramphoprion, which is most closely related to Ramphoprion, is represented by M. magnus new genus and species, a rare but distinctive taxon. Most species have long stratigraphic ranges within which important morphological changes can nonetheless be observed. The stratigraphic range of ramphoprionids includes, at least, the Ordovician to the Silurian. They are fairly rare in the Silurian of Gotland and where present they generally form less than 10 percent of the polychaete faunas, although occasionally reaching as much as 20 to 30 percent. Evolution, paleoecology, and surface structures of the investigated species are briefly discussed.

Clavularia amboinensis Burchardt, a species described as possessing simple, pinnule-less tentacles (a fact refuted by later authors) is confirmed to be as described and is transferred as a new combination to Acrossota Bourne — a genus dismissed until now by a number of authors. The species is compared to recently collected material with live photographs. A second new genus and species, Knopia octocontacanalis, is also described. This taxon resembles Acrossota in general form, but has tentacles where the pinnules appear as though they are fused side to side along the tentacles’ lateral margins. Preliminary phylogenetic analyses of two mitochondrial genes support placement of Knopia in Clavulariidae and retention of genus Acrossota in Bourne’s unrecognised family Acrossotidae.

The present paper reports on 22 species collected by the Brazilian Program of Living Resources in the Exclusive Economic Zone (REVIZEE). A new genus and species of Cribrilinidae, Corbuliporina crepida n. gen. et sp., is described, along with seventeen other new species: Chaperia brasiliensis n. sp., Amastigia aviculifera n. sp., Isosecuriflustra pinniformis n. sp., Cellaria subtropicalis n. sp., Melicerita brasiliensis n. sp., Arachnopusia haywardi n. sp., Smittina migottoi n. sp., Hippomenella amaralae n. sp., Rogicka joannae n. sp., Malakosaria atlantica n. sp., Turbicellepora winstonae n. sp., Rhynchozoon coalitum n. sp., Stephanollona angusta n. sp., Stephanollona arborescens n. sp., Aulopocella americana n. sp., Conescharellina cookae n. sp. and Conescharellina bocki n. sp. Chorizopora brongniartii (Audouin, 1826) is recorded for the first time in Brazilian waters and a new combination for Rhynchozoon arborescens Canu & Bassler, 1928 is established. New illustrations and taxonomic remarks are included for two little-known species from Brazil, Rogicka scopae (Canu & Bassler, 1928) and Fenestrulina ampla Canu & Bassler, 1928. A compilation of species recorded from deeper waters of the Brazilian coast is included.

Brachiopod Fauna

A brachiopod fauna of late Bathonian age recovered from the Kehailia Formation from Gebel Engabashi in northern Sinai consists of six species (two rhynchonellids and four terebratulids) referred to six genera, of which one genus and two species are new: Globirhynchia sphaerica (Cooper, 1989) new combination, Daghanirhynchia angulocostata Cooper, 1989, Ectyphoria sinaiensis new species, Cooperithyris circularis new genus and species, and new material: Avonothyris species A, and Ptyctothyris species A. The brachiopods described herein comprise a fauna located at the northern part of the Indo–African Faunal Realm within the Jurassic Ethiopian Province. They extend the geographic distribution of those taxa that show great affinity with the Jurassic brachiopod fauna of Saudi Arabia described by Cooper (1989). Differentiation of the endemic faunas that is so characteristic of many of these Ethiopian Province faunas is becoming more well-defined.

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.
