A New Species

Several biologically significant domes of pachycephalosaurid dinosaurs are described and figured. One unusual specimen from the Oldman Formation (Upper Cretaceous) of Alberta is placed into a new genus and another specimen from the same formation is assigned to a new species of Stegoceras. Domes referable to Stegoceras sp. (Judith River and Hell Creek Formations) are the first conclusive evidence of the presence of this genus in the United States. A large dome from the Oldman Formation of Alberta is referred to Pachycephalosaurus; this specimen is the oldest described to date and is the first record of this genus in Canada.Endocranial casts of Yaverlandia bitholus and Stegoceras validus are described along with a discussion of endocranial trends in pachycephalosaurids. The separation between the cerebrum and cerebellum found in Yaverlandia, and typical of ornithopods in general, is lacking in Stegoceras and Pachycephalosaurus. The loss of this separation may be the result of head butting.The family Pachycephalosauridae possesses sufficient ornithopod characters to justify their retention in that suborder. It does, however, represent an aberrant side branch of ornithopod evolution, which can best be visualized taxonomically by placing this family into a separate infraorder within the Ornithopoda.

The range of the cladoceran genus Daphniopsis is extended to North America with the description of a new species, Daphniopsis ephemeralis. Its morphological intermediacy suggests that Daphniopsis is ancestral to the genera Daphnia and Simocephalus. The genus appears to have a relict distribution and is restricted to marginal habitats.

AbstractLabopidea chloriza Uhler (1877) is synonymized with Tinicephalus simplex Uhler (1872). Labopidea brooksi n. sp. is described from Alberta and Saskatchewan. Orthotylus discolor Sahlberg, a European species now known to occur in North America, is transferred to Labopidea. Nine species currently placed in Labopidea are here removed from that genus. The new combinations are as follows: Labopidea atriseta Van Duzee is transferred to Hesperocapsus Knight, Orthotylus insignis Van Duzee is transferred to Ilnacorella Knight, Labopidea viridula Knight is transferred to Melanotrichus Reuter, and Labopidea utahensis Knight is synonymized with Diaphnidia heidemanni Knight (= Brachynotocoris heidemanni). Labopidicola n. gen. is described and Labopidea idahoensis Knight, L. planifrons Knight, L. ainsliei Knight, L. allii Knight, and L. geminata Johnston are transferred to it. Key to species of Labopidea is given.

A New Species

A total of 14 species in seven tingid genera have been described from the mid-Cretaceous Burmese (Kachin) amber from northern Myanmar, with very distinct paleofauna. Here, a new species of a new genus, Burmavianaida anomalocapitata gen. et sp. nov., is described from Kachin amber. This new species can be readily distinguished from the other described tingid taxa by the apparently smaller body and the structures of the pronotum and hemelytron. Burmavianaida gen. nov. shares the diagnostic characters with two clades composed of three extant subfamilies (Cantacaderinae + Tinginae) and Vianaidinae and may represent an extinct clade distinct from them. To the best of our knowledge, B. anomalocapitata sp. nov. is the smallest species of Tingidae among over 2600 described species. Our new finding supports the hypothesis of the miniaturization phenomenon of insects in Kachin amber, as suggested by previous studies.

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791
