Distinct Taxon

Exceptionally well preserved Lower Triassic conodonts from Oman include an array ofNeospathodusspecies, many of which are new. Those from the upper Lower Triassic, or Spathian, are described in conjunction with a restudy of conodont type material from Chios, Greece, and an assessment of contemporary collections from Pakistan and western North America. The taxonomic scope of three key species from Chios,Neospathodus homeri, N. triangularis, andN. gondolelloides, is revised. Seven new species are described from Oman:N. abruptus, N. brevissimus, N. brochus, N. crassatus, N. curtatus, N. pusillus, andN. symmetricus;and one new species,N. clinatus, is described from Pakistan. The alliedIcriospathodus collinsoniis also described from Oman. The occurrence and range ofNeospathodusspecies are presented in the context of the ammonoid succession in the Spathian of North America. BothN. homeriandN. triangularis, as revised, have shorter ranges and are more age diagnostic than previously thought.Neospathodus gondolelloidesis a distinct taxon, and not synonymous withChiosella timorensis.Five informal faunal divisions are identified based onNeospathodusand allied species. In ascending stratigraphic order, these are typified byIcriospathodus collinsoni, Neospathodus homeri, N. triangularis, N. symmetricus, andN. gondolelloides.Oman collections represent three of these faunas, which occur also in theColumbitesthroughProhungarites/Subcolumbitesammonoid beds of western U.S.A.

Pseudoomphalina kalchbrenneri is a Eurasian species. In North America the Pso. kalchbrenneri complex is represented by Pseudoomphalina anticostica sp. nov. and Pso. compressipes in the east and Pso. intermedia in the west. Pseudoomphalina farinacea and Pso. felleoides are later synonyms for Pso. compressipes. The somewhat similar Pseudolaccaria pachyphylla occupies a temperate band through Eurasia, confirmed by sequencing in both eastern and western North America. It differs from species of the Pso. kalchbrenneri complex by smaller size, finely granular pileus, non-decurrent gills, and lack of hymenial cystidia. All species of the Pso. kalchbrenneri complex are uncommon, and macroscopically similar. Pseudoomphalina kalchbrenneri and Pso. intermedia can be identified by their distribution (Europe and western North America, respectively) and lack of cystidia. The cystidiate eastern North American Pso. anticostica and Pso. compressipes can be differentiated by the smaller spores of the latter. Pseudoomphalina cokeri is the most ancestral species on the Pseudoomphalina lineage, while Clitocybe thujana and Agaricus apertus (Clitocybe/Clitocybula aperta) fall outside Pseudoomphalina and Pseudolaccaria. We add 21 new sequences to GenBank, including six types (Agaricus compressipes, Clitocybe felleoides, C. farinacea, C. intermedia, C. thujana, Agaricus apertus), and one new species (Pso. anticostica).

One New Species

AbstractOne new genus of Inocelliidae (Raphidioptera) with one new species and one undetermined specimen is described from the Eocene of North America: Paraksenocellia borealis new genus, new species from the early Eocene (Ypresian) Okanagan Highlands shale at Driftwood Canyon, British Columbia, Canada (a forewing), and Paraksenocellia species from the middle Eocene (Lutetian) of the Coal Creek Member of the Kishenehn Formation, northwestern Montana, United States of America (a hind wing). These are the oldest records of the family. The new genus possesses many character states that are rare in Inocelliidae, e.g., a very long pterostigma extending to ScP in both the forewings and hind wings; the forewing subcostal space has three crossveins; the forewing and hind wing AA1 are deeply forked; the crossvein between CuA and CuP is located far distad the crossvein 1r-m. Paraksenocellia is confidently a member of the Inocelliidae, as it possesses a proximal shift of the basal crossvein 1r-m (connecting R and M) in the forewing and the loss of the basal crossvein 1r-m in the hind wing, both apomorphies of the family. It shares some character states with the Mesozoic Mesoraphidiidae, which we consider to be mostly stem-group plesiomorphies.

Two New Species

Crosby and Bishop (1925) published a comprehensive revision of the New World genus Ceraticelus, and from time to time other species have been described as they appeared. The following descriptions of two additional species were based upon specimens in the American Museum of Natural History in New York. All type material was deposited in that institution.

Late Cambrian

Nine agnostoid species from late Cambrian (Paibian: Steptoean) boulders from the Cow Head Group in western Newfoundland fall into three biostratigraphically distinct faunas. The Glyptagnostus reticulatus Fauna contains only the eponymous species and correlates with the lower part of the Paibian and the basal Steptoean of North America. The “Innitagnostus” inexpectans Fauna is more diverse and likely correlates into part of the lower Steptoean Aphelaspis Zone of western North America. The youngest fauna, the Acmarhachis kindlei n. sp. Fauna, also includes species of Homagnostus and Pseudagnostus, as well as a second new species of Acmarhachis, A. whittingtoni. It probably correlates with the Dunderbergia Zone (mid-Pabian and mid-Steptoean) of the western United States. The Laurentian species Acmarhachis typicalis Resser (1938) and A. acuta (Kobayashi, 1938) are evaluated from restudy of type material, and types of “Innitagnostus” inexpectans (Kobayashi, 1938) from British Columbia are also reillustrated.

A redescription of Eurycercus (Teretifrons) glacialis Lilljeborg, 1901 is given, based solely on type material from Bering Island, Komandorski Islands (= Commander Islands), east of Kamchatka Peninsula, USSR. Eurycercus nigracanthus n.sp. is described from Newfoundland, and represents the most southerly known taxon in the subgenus Teretifrons. Although the subgenus is considered to be Holarctic in distribution, it is now seen that the range of E. glacialis is more restricted; in particular, at least one new species (and probably more) in the subgenus exists in North America.

Sixty-two taxa are recognized in this study of the species of Puccinia completing their life cycle on Heliantheae. Six new species are described: Puccinia guatemalensis Parmelee on Zexmenia spp. and Wedelia spp., P. ghiesbreghtii Parmelee on Wedelia ghiesbreghtii, P. abramsii Parmelee on Geraea viscida (= Encelia viscida), P. chloracae Parmelee on Viguiera spp., P. calanticariae Parmelee on Viguiera spp., and P. praetermissa Parmelee on Lagascea spp. Six new varieties are recognized: Puccinia electrae var. robusta Parmelee and P. electrae var. depressiporosa Parmelee on Zexmenia brevifolia, P. caleae var. cuernavacae Parmelee on Calea spp., P. cognata var. echinulata Parmelee on Verbesina spp., P. cognata var. fraseri Parmelee on Viguiera fraseri, and P. affinis var. triporosa Parmelee on Viguiera spp. Three taxa have been restored from synonomy under P. abrupta, viz. P. subglobosa, P. ximenesiae, and P. affinis, the last two parasitic on Verbesina spp., the first on Rhysolepis (= Viguiera). P. tithoniae, P. nanomitra, and P. ordinata, are reduced to synonomy with P. enceliae var. enceliae, P. iostephanes, and P. melampodii respectively. New combinations include: P. enceliae var. aemulans (Syd.) Parmelee and P. abrupta var. partheniicola (Jacks.) Parmelee. A key based on uredinial and telial characters, others based initially on the hosts, and a host index are provided. Each taxon is illustrated by a photomicrograph from type material. Distribution and host extensions, supplementary to those given in Arthur's Manual of the Rusts, are indicated.
