High-fidelity X-ray micro-tomography reconstruction of siderite-hosted Carboniferous arachnids

A new approach to maximize data recovery from siderite-hosted fossils is presented. Late Carboniferous trigonotarbids (Arachnida: Trigonotarbida) from Coseley, UK, were chosen to assess the potential of high-resolution X-ray micro-tomography (XMT). Three-dimensional computer reconstruction visualizes the animals at 20 µm or better resolution, resolving subtle and previously unseen details. Novel data recovered includes (possibly plesiomorphic) retention of endites on leg coxae of Cryptomartus hindi (Anthracomartidae) and highlights further similarities between this family and the Devonian Palaeocharinidae. Also revealed is a flattened body with robust anterior limbs, implying a hunting stance similar to modern crab spiders (Thomisidae). Eophrynus prestvicii (Eophrynidae) had more gracile limbs but a heavily ornamented body, with newly identified upward-pointing marginal spines on the opisthosoma. Its habitus is comparable with certain modern laniatorid harvestmen (Opiliones). These findings demonstrate the potential of XMT to revolutionize the study of siderite-hosted Coal Measures fossils.     

Taxonomic review of Bourguyiinae,cladistic analysis,and a new hypothesis of biogeographic relationships of the Brazilian Atlantic Rainforest (Arachnida: Opiliones,Gonyleptidae)

The subfamily Bourguyiinae Mello‐Leitão, 1923 (Gonyleptidae) is revised, and both phylogenetic and biogeographic hypotheses are proposed. Bourguyiinae is monophyletic, and is the sister group of the remainder of the Gonyleptidae species used for analysis, except for the Metasarcinae, which collectively is the sister group of Metavononoides orientalis Mello‐Leitão, 1923 (Cosmetidae). Bourguyiinae is divided into two genera: Bourguyia (six species) and Asarcus (four species). The genus‐level synonyms proposed here are as follows: Caldasius, Styloleptes, and Stylopisthos are junior synonyms of Bourguyia; Bogdana, Cnemoleptes, and Opisthoplites are junior synonyms of Asarcus. The species synonyms proposed here are as follows: Afranius amarali Mello‐Leitão, 1934 is a junior synonym of Bourguyia albiornata Mello‐Leitão, 1923 ; Drastus hamatus Roewer, 1943 and Styloleptes conspersus Piza, 1943 are junior synonyms of Bourguyia trochanteralis Roewer, 1930 ; Asarcus corallipes Simon, 1879 , Asarcus lutescens Sørensen, 1884 , Asarcus pallidus Mello‐Leitão, 1923 , and Opisthoplites ypsilon Sørensen, 1884 are junior synonyms of Asarcus longipes Kollar in Koch, 1839 ; Asarcus nigriconspersus Soares & Soares, 1945 is a junior synonym of Asarcus ingenuus Melo‐Leitão, 1940. New species described are: Bourguyia bocaina sp. nov. (Serra da Bocaina, São José do Barreiro, São Paulo), Bourguyia vinosa sp. nov. (E.B. Boracéia, Salesópolis, São Paulo), and Asarcus putunaberaba sp. nov. (Parque Nacional do Caparaó, Alto Caparaó, Minas Gerais). Bourguyiinae is endemic to the Atlantic Rainforest in the Brazilian states of Minas Gerais, Rio de Janeiro, São Paulo, and Paraná. Based on the modified data matrix of Pinto‐da‐Rocha et al., we propose a new biogeographical hypothesis for the Atlantic Rainforest. We suggest that Bourguyiinae species were originally distributed from the coastal region of Paraná to the north of Rio de Janeiro and south‐east of Minas Gerais, with subsequent dispersals both to northern and southern areas. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 156 , 319–362.     

A phylogenetic analysis of the nursery-web spider family Pisauridae, with emphasis on the genera Architis and Staberius (Araneae: Lycosoidea)

This study presents a general cladistic analysis of pisaurid genera, with emphasis on the Neotropical genera Architis Simon and Staberius Simon. The analysis was based on a matrix with 21 terminal taxa: eight species of Architis , Staberius spinipes (Taczanowski), seven exemplars of other pisaurid genera and five outgroup taxa. These terminals were scored for 59 morphological and three behavioural characters. An analysis with all characters equally weighted resulted in two most parsimonious trees, differing only in the position of Architis colombo Santos. In both trees Pisauridae arouse as a monophyletic group, and the exemplars of Architis composed a clade with S. spinipes . Contrary to hypotheses from the literature, Thalassius Simon emerged as sister-group of all remaining pisaurids, not as a close relative of Dolomedes Latreille. The genera Tinus F.O.P. -Cambridge and Thaumasia Perty appeared in the trees as the closest relatives of Architis and Staberius Simon. The analysis strongly supported S. spinipes as the sister-group of A. helveola (Simon), indicating that Architis as currently delimited is paraphyletic. Based on these results, Staberius is considered a subjective junior synonym of Architis . Additionally, the genus Mimicosa Petrunkevitch, originally described in Tetragnathidae, is transferred to Pisauridae and considered a junior synonym of Architis . Two species are proposed as junior synonyms of A. spinipes comb.n. Mimicosa spinosa Petrunkevitch and Staberius lemoulti Caporiacco.     

A REVISION OF THE FOSSIL PIRATE SPIDERS (ARACHNIDA: ARANEAE: MIMETIDAE)

Abstract:  Fossil pirate spiders (Araneae: Mimetidae) are revised. The extinct genera Succinero Wunderlich, 2004 a and Palaeoero Wunderlich, 2004 a are interpreted as synonyms of the extant genus Ero C. L. Koch, 1836. We recognize here the following fossil species as valid: E. carboneana Petrunkevitch, 1942, E. longitarsus (Wunderlich, 2004 a ) comb. nov. and E. permunda Petrunkevitch, 1942, all from Baltic amber (Paleogene: Eocene), and E. rovnoensis (Wunderlich, 2004 b ) comb. nov. from Rovno (Ukranian) amber (Paleogene: Eocene). Mimetus bituberculatus Wunderlich, 1988 from Dominican Republic amber (Neogene: Miocene) can be assigned to a specifically American clade of Mimetus Hentz, 1932. Mimetus brevipes Wunderlich, 2004 a from Baltic amber is synonymized with M. longipes Wunderlich, 2004 a syn. nov. Of the other species (all Baltic amber), Ero aberrans Petrunkevitch, 1958 lacks taxonomically useful characters. Ero setulosa C. L. Koch and Berendt, 1854 is based on two non-conspecific, and non-mimetid, spiders. Mimetarchaea gintaras Eskov, 1992 is a subadult male mimetid. The putative oarcine 'missing link' Praeoarces exitus Wunderlich, 2004 a is a subadult female mimetine. All four are treated here as nomina dubia . Other fossil mimetid species in the literature are nomina nuda .     

Revision,cladistic analysis and biogeography of Typhochlaena C. L. Koch, 1850, Pachistopelma Pocock, 1901 and Iridopelma Pocock, 1901 (Araneae,?Theraphosidae,Aviculariinae)

Three aviculariine genera endemic to Brazil are revised. Typhochlaena C. L. Koch, 1850 is resurrected, including five species; Pachistopelma Pocock, 1901 includes two species; and Iridopelma Pocock, 1901, six species. Nine species are newly described: Typhochlaena amma sp. n., Typhochlaena costae sp. n., Typhochlaena curumim sp. n., Typhochlaena paschoali sp. n., Pachistopelma bromelicola sp. n., Iridopelma katiae sp. n., Iridopelma marcoi sp. n., Iridopelma oliveirai sp. n. and Iridopelma vanini sp. n. Three new synonymies are established: Avicularia pulchra Mello-Leitão, 1933 and Avicularia recifiensis Struchen & Brändle, 1996 are junior synonyms of Pachistopelma rufonigrum Pocock, 1901 syn. n., and Avicularia palmicola Mello-Leitão, 1945 is a junior synonym of Iridopelma hirsutum Pocock, 1901 syn. n. Pachistopelma concolor Caporiacco, 1947 is transferred to Tapinauchenius Ausserer, 1871, making the new combination Tapinauchenius concolor (Caporiacco, 1947) comb. n. Lectotypes are newly designed for Pachistopelma rufonigrum Pocock, 1901 , Iridopelma hirsutum Pocock, 1901 and Pachistopelma concolor Caporiacco, 1947. Cladistic analyses using both equal and implied weights were carried out with a matrix comprising 62 characters and 38 terminal taxa. The chosen cladogram found with X-Pee-Wee and concavity 6 suggests they are monophyletic. All species are keyed and mapped and information on species habitat and area cladograms are presented. Discussion on biogeography and conservation is provided.     

Intraindividual variability in Sinonamuropteridae forewing venation (Grylloblattida; Late Carboniferous): taxonomic and nomenclatural implications

The family Sinonamuropteridae has been erected for nine fossil insect species from the Late Carboniferous Tupo Formation (Ningxia, China), each represented by a single isolated forewing. The family has been assigned to the order Diaphanopterodea (extinct palaeopteran order). We investigated the forewing venation pattern and its variability in this family based on an abundant collection from the same locality. Based on new data on Chelopterum peregrinum Carpenter, 1950 (Grylloblattida; Lower Permian; Wellington Formation, U.S.A.) and the new material, we demonstrate that the nine sinonamuropteridaean species form a single one: Sinonamuropteris ningxiaensis Peng et al., 2005 . The following genera are considered as synonyms of Sinonamuropteris: Separatonerva Peng et al., 2005 syn.n. , Combonerva Peng et al., 2005 syn.n. and Tectonerva Peng et al., 2005 syn.n. The following species (all with Peng et al., 2005 , as their authority) are considered as synonyms of S. ningxiaensis: Separatonerva longa syn.n. , Separatonerva qilianshanensis syn.n. , Combonerva granulata syn.n. , Combonerva huangheensis syn.n. , Tectonerva longovata syn.n. , Sinonamuropsis zhongweiensis syn.n. , Sinonamuropsis rugoverrucosa syn.n. , Sinonamuropsis xiaheyanensis syn.n. The family must be assigned to the neopteran order Grylloblattida.     

Systematic position of the enigmatic African cycad moths: an integrative approach to a nearly century old problem (Lepidoptera: Geometridae,Diptychini)

The systematic position and hierarchical level of the moth taxon Diptychini Janse (Lepidoptera: Geometridae), the cycad moths, has remained controversial. This is partly due to their unique morphological and biological characteristics. To study the systematics, comprehensive molecular analyses of eight genes, in total 6157 bp, were carried out. We used Bayesian inference to construct phylogenetic trees. The first analysis (46 Geometridae and 7 non‐Geometridae taxa, representing all recently recognised Geometridae subfamilies) demonstrated that the Diptychini belong to the Geometridae subfamily Ennominae. The second analysis, focused on the Ennominae (70 taxa, representing 28 of 30 recently recognised Ennominae tribes worldwide), found that the Diptychini are nested well within the Ennominae; it is monophyletic and associated with the complex of southern Hemisphere Nacophorini, refuting many of the earlier hypotheses about Diptychini relationships. The Diptychini are considered tentatively valid at the tribe level, but relationships with the Nacophorini and the Lithinini need further research. The molecular findings were evaluated from a morphological point of view, which are mostly in agreement with the molecular results. The Diptychini genera are illustrated and characterised using morphological and life‐history traits. Within the Diptychini, three genera are considered valid. Durbana Warren (described in 1904) is proposed as a junior synonym of Veniliodes Warren (described in 1894) ( n.syn. ). Monotypic Larentioides Prout is combined with the tribe Lithinini ( n.comb .). Homonymy of Diptychini Mirza (described in 1991) (Pisces: Cyprinidae, Schizothoracinae) with Diptychini Janse (described in 1933) (Lepidoptera: Geometridae, Ennominae) is noted, the former requiring a replacement name.     

Morphological phylogeny and classification of Winthemiini (Diptera: Tachinidae: Exoristinae)

Winthemiini is a worldwide tribe in the subfamily Exoristinae (Diptera: Tachinidae) with 200 species in 16 genera. We confirm the monophyly of Winthemiini and examine relationships among the constituent genera based on a parsimonious analysis of adult morphological characters for 53 species representing 12 out of 16 currently recognized Winthemiini genera. As a result, Winthemiini is divided into three major clades, with relationships as follows: ((Rhaphiochaeta [Ossidingia, Nemorilla]) ((Hemisturmia [Avibrissosturmia, Triodontopyga]) ([Smidtia, Winthemia])). A revised classification system for Winthemiini is proposed, recognizing 12 genera. Four new synonymies are proposed – Diotrephes and Chesippus as junior synonyms of Smidtia, and Hemisturmiella and Parachetolyga as junior synonyms of Winthemia – along with four new combinations: Winthemia brasiliana (Guimarães) comb.n. , W. metopia (Bischof) comb.n. , Smidtia atriventris (Walker) comb.n. , and S. notialis (Reinhard) comb.n.     

Trichopsomyia ochrozona (Stackelberg, 1952) (Diptera: Syrphidae) recorded from Iran for the first time with a key to the West Palaearctic Trichopsomyia Williston, 1888 species

The hoverfly Trichopsomyia ochrozona (Stackelberg, 1952) (Diptera: Syrphidae) is recorded for the first time from Iran. An illustrated key to the West Palaearctic species of Trichopsomyia is presented. Illustrations of the puparium of Trichopsomyia joratensis Goeldin, 1997 and the larva and puparium of T. ochrozona are given and their larval and adult habitats are described. A short discussion is given on the known larval habitat of other West Palaearctic Trichopsomyia species. Some of the synonyms have been evaluated and Pipiza melancholica Meigen, 1822 is withdrawn from synonymy of Trichopsomyia flavitarsis (Meigen, 1822) and is considered as a junior synonym of Musca viduata Linnaeus, 1758 syn. nov.     

Phylogenetic relationships of Acronictinae with discussion of the abdominal courtship brush in Noctuidae (Lepidoptera)

We present results of an eight‐gene molecular study of the subfamily Acronictinae and related Noctuidae. Amphipyrinae are recovered as sister to Acronictinae, but with weak support – not surprisingly, the content of the two subfamilies has often been mixed in classifications. Balsinae, previously placed near Acronictinae or within Noctuinae, is recovered within an unresolved polytomy of Cuculliinae, Eustrotiinae, Raphiinae and Dilobinae. Gerbathodes Warren, Moma Hübner and Nacna Fletcher are excluded from Acronictinae. Three genera recently transferred into the subfamily – Cerma Hübner, Chloronycta Schmidt & Anweiler and Comachara Franclemont – are confirmed as acronictines. Lophonycta Sugi (the type genus of Lophonyctinae) is returned to the Acronictinae. Sinocharis Püngeler, formerly considered to be Acontiinae or as the basis of its own subfamily Sinocharinae, is nested within early diverging Acronictinae genera. Both subfamilies are formally synonymized: i.e. Lophonyctinae syn.n. and Sinocharinae syn.n. Nine acronictine genus‐level taxa were found to nest within the nominate genus Acronicta Ochsenheimer: Eogena Guenée, Hyboma Hübner, Hylonycta Sugi, Jocheaera Hübner, Oxicesta Hübner, Simyra Ochsenheimer, Subacronicta Kozhanchikov, Triaena Hübner, and Viminia Chapman. Eogena, Oxicesta, and Simyra, currently treated as valid genera, nest within terminal clades of the genus Acronicta and are here subsumed within the genus: Eogena syn.n. , Oxicesta syn.n. and Simyra syn.n. Four well‐supported species groups within Acronicta are identified: the alni clade, the leporina clade, the nervosa clade and the psi clade. While many previous treatments have stated explicitly that Acronictinae lack abdominal scent brushes, or excluded genera with brushes from the subfamily, we show that well‐developed brushes are present in three early diverging acronictine genera: Cerma, Lophonycta, and Sinocharis. We illustrate and describe the brushes of all three genera, and briefly review the taxonomic distribution of the anterior abdominal courtship brushes in Noctuidae, emphasizing the labile evolutionary distribution of these structures.     

Neoaplectana Steiner, 1929 a junior synonym of Steinernema Travassos, 1927 (Nematoda; Rhabditida)

Summary A type specimen of Steinernema kraussei and a population of this nematode from the type host were compared with three species of Neoaplectana. No characters were found to separate the two genera and so Neoplectana Steiner, 1929 is considered to be a junior synonym of Steinernema Travassos, 1927. Valid species now included within the genus Steinernema are: S. kraussei (Steiner, 1923) Travassos, 1927 (type species); S. glaseri (Steiner, 1929) n.comb.; S. feltiae (Filipjev, 1934) n.comb. and S. bibionis (Bovien, 1937) n.comb. A key is given to these four species and their junior synonyms are listed.     

One Beringian genus less: A re‐assesment of Pacifimyxas Kruglov & Starobogatov, 1985 (Mollusca: Gastropoda: Lymnaeidae) questions the current estimates of Beringian biodiversity

The taxonomic position of three nominal species of lymnaeid snails placed by Kruglov & Starobogatov (1993) into the subgenus Lymnaea (Pacifimyxas) Kruglov & Starobogatov, 1985, has been re‐assessed based on a molecular genetic study of topotypic specimens and an examination of the type series and other materials available. It has been shown that the two species, Lymnaea (Pacifimyxas) magadanensis Kruglov & Starobogatov, 1985 and Lymnaea (Pacifimyxas) streletzkajae Kruglov & Starobogatov, 1985, are identical with the species Kamtschaticana kamtschatica (Middendorff, 1850) and must be treated as its junior synonyms. Hence, Pacifimyxas becomes a junior synonym of Kamtschaticana Kruglov & Starobogatov, 1984. The taxonomic identity of the third species of Pacifimyxas, Lymnaea (Pacifimyxas) perpolita, remains obscure, and this species is considered here as taxon inquirendum. Two other nominal species, Lymnaea aberrans (Westerlund, 1897) and Lymnaea middendorffi (W. Dybowski, 1904), have been synonymized with K. kamtschatica based on morphological and geographical evidence. The lectotype of Limnaea peregra var. middendorffi is designated. The actual level of species richness in the Beringian freshwater malacofauna may be 20–25% lower than it was determined on the basis of the traditional system. Some implications of this outcome for the biogeography of the Beringian freshwater fauna are discussed.     

Cladistic analysis of Coenosiini (Diptera: Muscidae: Coenosiinae)

The phylogenetic relationships among world genera of Coenosiini (Diptera: Muscidae: Coenosiinae) were investigated using parsimony. The analysis involved forty‐six ingroup terminal taxa, representing 100% of the genera currently assigned to this tribe, three outgroups and sixty‐seven adult male and female morphological characters. The monophyly of Coenosiini is confirmed by the position of the three katepisternal bristles, equidistant from each other and placed at the points of an equilateral triangle. Genera Andersonosia, Agenamyia, Anthocoenosia, Drepanocnemis, Pachyceramyia and Rhabdotoptera are removed from Coenosiini and temporarily placed in Limnophorini. The other genera fall into two groups: the Lispocephala‐group, comprised of genera with mainly Old World species and the Nearctic genus Pentacricia; and the Coenosia‐group, with the highest level of generic diversity in South America. Each group is defined by synapomorphies of its constituent genera: Lispocephala‐group by the presence of a posteroventral apical seta on the hind tibia, the presence of two arms in male sternite 6 (not forming a ring) and the short or very short female ovipositor; the Coenosia‐group by the presence of a developed epiproct and narrow sternites 6 and 7 of the female ovipositor. The following new generic synonymies are proposed (junior synonyms in parentheses): Lispocephala Pokorny (=Pectiniseta Stein), Coenosia Meigen (=Tenuicosta Stein; Dexiopsis Pokorny), Neodexiopsis Malloch (=Haroldopsis Albuquerque), Pilispina Albuquerque (=Levallonia Albuquerque; Noelia Albuquerque; Parvomusca Medeiros; Cholomyioides Albuquerque), Apsil Malloch (=Raymondomyia Malloch), Stomopogon Malloch (=Angolia Malloch; Angolina Pont) and Pygophora Schiner (=Chouicoenosia Cui & Xue).     

A total‐evidence phylogenetic analysis of Hormaphidinae (Hemiptera: Aphididae), with comments on the evolution of galls

A phylogenetic analysis of Hormaphidinae is presented based on a total‐evidence approach. Four genes (two mitochondrial, COI and CytB, and two nuclear, EF‐1α and LWO) are combined with 65 morphological and seven biological characters. Sixty‐three hormaphidine species representing three tribes and 36 genera as well as nine outgroups are included. Parsimony and model‐based approaches are used, and several support values and implied weighting schemes are explored to assess clade stability. The monophyly of Hormaphidinae and Nipponaphidini is supported, but Cerataphidini and Hormaphidini are not recovered as monophyletic. Based on the parsimony hypothesis from the total‐evidence analysis, the phylogenetic relationships within Hormaphidinae are discussed. Cerataphidini is re‐delimited to exclude Doraphis and Tsugaphis, and Hormaphidini is redefined to include Doraphis. Ceratocallis Qiao & Zhang is established as a junior synonym of Ceratoglyphina van der Goot, syn. nov. Lithoaphis quercisucta Qiao, Guo & Zhang is transferred to the genus Neohormaphis Noordam as Neohormaphis quercisucta (Qiao, Guo & Zhang) comb. nov. Galls have evolved independently within three tribes of Hormaphidinae. In Cerataphidini, pseudogalls are ancestral, both single‐cavity and multiple‐cavity galls have evolved once, and galls appear to have evolved towards greater complexity. Galling on secondary hosts has evolved twice in hormaphidines.     

Multi‐locus phylogeny of African pipits and longclaws (Aves: Motacillidae) highlights taxonomic inconsistencies

The globally distributed avian family Motacillidae consists of five to seven genera (Anthus, Dendronanthus, Tmetothylacus, Macronyx and Motacilla, and depending on the taxonomy followed, Amaurocichla and Madanga) and 66–68 recognized species, of which 32 species in four genera occur in sub‐Saharan Africa. The taxonomy of the Motacillidae has been contentious, with variable numbers of genera, species and subspecies proposed and some studies suggesting greater taxonomic diversity than currently recognized (five genera and 67 species). Using one nuclear (Mb) and two mitochondrial (cyt b and CO1) gene regions amplified from DNA extracted from contemporary and museum specimens, we investigated the taxonomic status of 56 of the currently recognized motacillid species and present the most taxonomically complete and expanded phylogeny of this family to date. Our results suggest that the family comprises six clades broadly reflecting continental distributions: sub‐Saharan Africa (two clades), the New World (one clade), Palaearctic (one clade), a widespread large‐bodied Anthus clade, and a sixth widespread genus, Motacilla. Within the Afrotropical region, our phylogeny further supports recognition of Wood Pipit Anthus nyassae as a valid species, and the treatment of Long‐tailed Pipit Anthus longicaudatus and Kimberley Pipit Anthus pseudosimilis as junior subjective synonyms of Buffy Pipit Anthus vaalensis and African Pipit Anthus cinnamomeus, respectively. As the disjunct populations of Long‐billed Pipit Anthus similis in southern and East Africa are genetically distinct and geographically separated, we propose a specific status for the southern African population under the earliest available name, Nicholson's Pipit Anthus nicholsoni. Further, as our analyses indicate that Yellow‐breasted Pipit Anthus chloris and Golden Pipit Tmetothylacus tenellus are both nested within the Macronyx longclaws, we propose transferring these species to the latter genus.     

Phylogeny,character evolution and tribal classification in Crambinae and Scopariinae (Lepidoptera,Crambidae)

Crambinae (2047 spp.) and Scopariinae (577 spp.) are two major groups of pyraloid moths with a worldwide distribution. Their larvae feed predominantly on Poales and Bryophyta, with many cereal crop pests. We present the first molecular phylogeny of the two groups based on five nuclear genes and one mitochondrial gene (total = 4713 bp) sampled for 58 crambine species representing 56 genera and all tribes, 33 scopariine species representing 12 genera, and species in several other crambid lineages. Maximum likelihood and Bayesian analyses of the molecular data resolve suprageneric relationships in Crambinae and Scopariinae, whereas relationships between these and other subfamilies remain ambiguous. Crambinae and Scopariinae are each recovered as monophyletic groups, and Erupini, formerly regarded as an ingroup of Midilinae, is recovered as a possible sister group of Crambinae. The tree topology suggests the following two major changes within Crambinae: Prionapterygini Landry syn.n. of Ancylolomiini Ragonot stat. rev. and Myelobiini Minet syn.n. of Chiloini Heinemann. Argyriini Munroe is monophyletic after the transfer of Pseudocatharylla Bleszynski and Vaxi Bleszynski to Calamotrophini. Crambini, Diptychophorini and Haimbachiini are monophyletic after the exclusion of Ancylolomia Hübner, Euchromius Guenée, Micrelephas Dognin and Miyakea Marumo from Crambini, as well as Microchilo Okano from Diptychophorini. Euchromiini tribe n. is described for Euchromius. Microcramboides Bleszynski syn.n. and Tortriculladia Bleszynski syn.n. are synonymized with Microcrambus Bleszynski. In Scopariinae, Caradjaina Leraut syn.n. and Cholius Guenée syn.n. are synonymized with Scoparia Haworth, and, in addition, Dasyscopa Meyrick syn.n. , Dipleurinodes Leraut syn.n. and Eudipleurina Leraut syn.n. are synonymized with Eudonia Billberg. Micraglossa melanoxantha (Turner) (Scoparia) comb.n. is proposed as a new combination. We analysed 27 morphological characters of wing venation, tympanal organs, male and female genitalia, as well as host plant data and egg‐laying behaviour. The ancestral character‐state reconstructions confirmed previous apomorphies and highlighted new apomorphies for some of the newly recovered clades. The derived, nonadhesive egg‐dropping behaviour is found to have evolved at least twice in Crambinae and is associated with the use of Pooideae as host plants.

Arachniden-Neufunde im mitteleuropäischen Unterkarbon bis Perm — Beitrag zur Revision der Familie AphantomartidaePetrunkevitch 1945 (Arachnida, Trigonotarbida)

On the basis of rich new material covering a broad time span from the Lower Carboniferous (Viséan) to the Lower Permian (Asselian), the trigonotarbid family AphantomartidaePetrunkevitch 1945 is revised. According to investigations presented here it includes only one genus,Aphantomartus Pocock 1911, with two species,A. pustulatus (Scudder 1884) undA. areolatus (Pocock 1911). Many synonyms that existed in the literature until now, the stratigraphic occurrence, palaeobiogeographic distribution as well as taphonomic aspects are discussed. Besides some newly found as well as newly investigated specimens both the oldest and the youngest (the youngest trigonotarbid hitherto known) representatives of the family are presented.     

Blastogeny in tabulate corals: case studies using X‐ray microtomography

X‐ray microtomography (XMT) is a non‐invasive and non‐destructive method that has often been used to study fossils. It allows serial sections to be made as little as few micrometers apart; such a resolution is unachievable for classical serial sectioning; moreover, in contrast to the latter, the specimen is not destroyed. Microtomography can, however, be applied only in cases where differences in X‐ray absorption between the skeleton and its infilling are great. We show that this method may be also applied to tabulate corals. Case studies of blastogeny are based on Silurian (Aulopora, Favosites) and Devonian (Thamnopora) specimens from Poland. We show that the sequence of events in the blastogeny of Aulopora sp. is different from that of ‘Aulopora serpens minor’ from the Devonian of the Holy Cross Mountains and similar to auloporids from the Devonian of England. Blastogeny in Favosites is very similar to that known from the related genera Squameofavosites and Thamnopora. This suggests that members of the genus Aulopora may be more diversified within the genus (as presently understood) than genera within the Favositidae.
