Newly discovered fossils from Eocene rocks of the Quimper Sandstone, Washington, USA, constitute the first reported occurrence of the albuneid genus Lophomastix Benedict, 1904, in the fossil record. Lophomastix and the closely related genus Blepharipoda Randall, 1839, are thought to be basal taxa within the decapod family Albuneidae Stimpson, 1858, based upon possession of primitive trichobranch gill structures. The occurrence of Lophomastix antiqua new species in Eocene deposits indicates that the genus is at least as old as the more derived genus, Albunea Weber, 1795, as would be expected for the basal taxon within the family. Based upon examination of type material, Blepharipoda brucei Rathbun, 1926, is herein removed from that genus and placed within the Paguroidea as Pagurus brucei (Rathbun, 1926) new combination.

A Current

ABSTRACTIcacinaceae Miers are a family of trees, shrubs, and lianas with a current pantropical distribution. The family is well known in the fossil record, especially from the Palaeogene of Europe and North America, with the modern genus Iodes being particularly well represented. Here, we describe five new species of Iodes based on fossil endocarps with horn-like protrusions from the late Palaeocene Rivecourt deposits (Oise, France). Moreover, we propose a new combination for Iodes israelii Soudry & Gregor, as Icacinicarytes israelii (Soudry & Gregor) Del Rio, Thomas & De Franceschi, because it lacks the diagnostic morphological and anatomical characters of the genus Iodes. The significance of papillae, which has been emphasised in the literature, is discussed in light of new data, and a more standardised system of terminology is proposed. Given that, among modern members of Iodes, horn-like protrusions are only known from Asian species; the fossils described here suggest an affinity between the late Palaeocene flora of Europe and the modern flora of Asia. Finally, this study represents the first detailed investigation of Icacinaceae from the Paris Basin, where palaeocarpology remains understudied.

Two species of Jurodidae: Jurodes ignoramus and Jurodes minor are redescribed, new characters presented, and characters from original descriptions are phylogenetically reevaluated, justifying a placement of the family within the suborder Archostemata. The new species Jurodes shef sp. nov. from the Lower Cretaceous locality Khasurty (Berriasian-Barremian, Zakamenskiy district, Buryatia Republic, Russia) is described and 2 new specimens of J. ignoramus Ponomarenko, 1985 and 5 additional specimens of J. minor Ponomarenko, 1990 are recorded. Jurodids from Khasurty are morphologically closer to those from Daohugou locality (Middle–Upper Jurassic, Inner Mongolia, China).

Currently, the Onisicdea (terrestrial isopods) is a massive Crustacea suborder of more than 3 700 species, but our knowledge of their paleodiversity is poor. In this paper, we present ten fossils of Crinocheta, the largest clade within the Onisicdea, discovered in Early Miocene (23 Ma) amber of Chiapas. We described three new genera and six new species including Palaeolibrinus spinicornis gen. nov. sp. nov., Armadilloniscus miocaenicus sp. nov., Archeostenoniscus robustus gen. nov. sp. nov., Archeostenoniscus mexicanus sp. nov., Palaeospherarmadillo mazanticus gen. nov. sp. nov., and Palaeospherarmadillo rotundus sp. nov. This study represents the first fossil record of the family Detonidae, Olibrinidae, and “Stenoniscidae”. From a paleoenvironmental reconstruction perspective, the oniscidean fauna presented here supports a particularly wet paleoenvironment, under brackish water influence, similar to an estuary.

The Status

The family Harrimaniidae (Hemichordata: Enteropneusta) is revised on the basis of morphological characters. The number of harrimaniid genera is increased to nine by the addition of Horstia n. gen., Mesoglossus n. gen., Ritteria n. gen. and Saxipendium, a genus previously assigned to the monospecific family Saxipendiidae. The number of species is increased to 34, resulting from the description of five new species from the eastern Pacific — Horstia kincaidi, Mesoglossus intermedius, M. macginitiei, Protoglossus mackiei and Ritteria ambigua. A description is supplied for a sixth harrimaniid species, Stereobalanus willeyi Ritter & Davis, 1904, which previously had the status of a nomen nudum. Four harrimaniids previously assigned to the genus Saccoglossus are transfered to the genus Mesoglossus — M. bournei, M. caraibicus, M. gurneyi and M. pygmaeus, while Saccoglossus borealis is reassigned to the genus Harrimania. Notes on habitat and zoogeography are included for the seven foregoing species and a table of diagnostic characters for existing and new species and a dichotomous key to the enteropneust families and harrimaniid genera are provided. Finally, a phylogenetic hypothesis concerning the Harrimaniidae is postulated, with discussion on the evolution of the group.

Seymour Island

Leptomaria antipodensis and Leptomaria hickmanae are described from the Upper Cretaceous [Maastrichtian] Lopez de Bertodano Formation, Seymour Island, and represent the first Mesozoic records of the family Pleurotomariidae from Antarctica. Leptomaria stillwelli, L. seymourensis, Conotomaria sobralensis and C. bayeri, from the Paleocene [Danian], Sobral Formation, Seymour Island, are described as new. Leptomaria larseniana (Wilckens, 1911) new combination, also from the Sobral Formation, is redescribed based on better-preserved material. The limited diversity of the pleurotomariid fauna of Seymour Island is more similar to that of the Late Cretaceous faunas of Australia and New Zealand in terms of the number of genera and species, than to the older, more diverse faunas of South America, southern India, or northwestern Madagascar, supporting the status of the Weddelian Province as a distinct biogeographic unit. The increase in the species richness of this fauna during the Danian may be due to the final fragmentation of Gondwana during this period.

A New Species

Recently, we (Akkari & Enghoff 2011) described a new species of the genus Rharodesmus Schubart, 1960, discussing the taxonomic state of the family Pyrgodesmidae and providing notes on the four genera occurring in the west Palaearctic area. However, we failed to present details on the holotype of the new species, which we now provide in this note in order to make the species name available. Thus, we describe here the new species Rharodesmus tabarkensis Akkari & Enghoff by reference to the full description given in Akkari & Enghoff (2011) with the following information on the type material: Holotype ♂, TUNISIA, NW, Jendouba Governorate, Tabarka, N36°57.8, E8°44.6, alt. < 40 m, coastal slope below the Genoese fort, under stones, 9.iii.2009, N. Akkari & H. Enghoff leg. (Natural History Museum of Denmark, Zoological Museum, University of Copenhagen, ‒ ZMUC); Paratypes: 12 ♂♂, 8 ♀♀, 14 juveniles, same locality and date as holotype, N. Akkari & H. Enghoff leg. (ZMUC).

The first report of Apistobranchus Levinsen, 1883 (Family Apistobranchidae) in Antarctica was presented by Hartman (1967). Two species were later described: Apistobranchus glacierae Hartman, 1978 and Apistobranchus gudrunae Hartmann- Schröder & Rosenfeldt, 1988, which differed from A. glacierae mainly by having compound setae. Subsequently, ecological studies in Antarctica have identified both of these species. On the status of Antarctic Apistobranchus, we concluded that there is up to now, only one valid species, A. glacierae. The character ‘compound-setae’ referred for A. gudrunae is in fact simple limbate ones eventually splintered as described for A. glacierae. Other characters, also previously considered as diagnostics for A. gudrunae, did not differ in both species as shown by the observation of several specimens of different sizes and type material of A. glacierae and A. gudrunae. All the reports on the densities of Antarctic apistobranchids, including ours, show that they have higher values in finer sediments of 20 and 40 m depth. The need of additional work, including the rearing of specimens in the laboratory and plankton analysis, is emphasized.

Abstract The phylogeny and systematics of cordycipitoid fungi have been extensively studied in the last two decades. However, systematic positions of some taxa in the family Cordycipitaceae have not yet been thoroughly resolved. In this study, a new phylogenetic framework of Cordycipitaceae is reconstructed using multigene (nrSSU, nrLSU, tef-1α, rpb1 and rpb2) sequence data with large-scale taxon sampling. In addition, ITS sequence data of species belonging to the Lecanicillium lineage in the family Cordycipitaceae are used to further determine their phylogenetic placements. Based on molecular phylogenetic data together with morphological evidence, two new genera (Flavocillium and Liangia), 16 new species and four new combinations are introduced. In the new genus Flavocillium, one new species F. bifurcatum and three new combinations previously described as Lecanicillium, namely F. acerosium, F. primulinium and F. subprimulinium, are proposed. The genus Liangia is built by the new species Lia. sinensis with Lecanicillium-like asexual morph, isolated from an entomopathogenic fungus Beauveria yunnanensis. Due to the absence of Paecilomyces hepiali, an economically and medically significant fungus, in the earlier phylogenetic analyses, its systematic position has been puzzling in both business and academic communities for a long time. Here, P. hepiali is recharacterized using the holotype material along with seven additional samples. It is assigned to the genus Samsoniella (Cordycipitaceae, Hypocreales) possessing Cordyceps-like sexual morph and Isaria-like asexual morph, and thus a new combination, namely S. hepiali is proposed. An additional nine new species in Samsoniella are described: S. alpina, S. antleroides, S. cardinalis, S. cristata, S. lanmaoa, S. kunmingensis, S. ramosa, S. tortricidae and S. yunnanensis. Four new species in Cordyceps are described: C. chaetoclavata, C. cocoonihabita, C. shuifuensis and C. subtenuipes. Simplicillium yunnanense, isolated from synnemata of Akanthomyces waltergamsii, is described as a new species.

During an examination of type material of the New World endomychid genus Bystus Guérin-Méneville (Anamorphinae), the type series of Alexia hirtula Kirsch from Peru was found to contain a mixture of different taxa, none of which belong to the genus Bystus, the subfamily Anamorphinae, or even the family Endomychidae. Alexia hirtula is transferred to Delphastus Casey (Coccinellidae: Microweiseinae: Serangiini), establishing the new combination, Delphastus hirtulus (Kirsch), and a lectotype is designated. Of the three paralectotypes, one appears to be conspecific with the lectotype, one is identified as an undescribed species of Microscymnus Champion (Coccinellidae: Cryptognathini), and one, a partial specimen lacking the head, pronotum, and one elytron, is identified as a species of Leiodidae in the tribe Scotocryptini, probably Aglyptinus Cockerell. A diagnosis and redescription of D. hirtulus is provided, and Gordon’s (1994) key to Delphastus is modified to accommodate the newly transferred species. The historical classification of D. hirtulus is discussed along with characters justifying its revised placement.
