Aphids of the genus Dysaphis Börner (Homoptera, Aphididae) living on plants of the family polygonaceae

All morphs of two species of the genus Dysaphis, D. radicola (Mordv.) and D. rumecicola (Hori), living on plants of the family Polygonaceae, are described in detail. Morphometrical analysis has shown that D. radicola meridialis Shaposhnikov, 1964 is merely a synonym of D. radicola radicola (Mordvilko, 1897), and D. albocinerea (Hille Ris Lambers, 1956) and D. rheicola Daniyarova ex Narzikulov et Daniyarova, 1971, synonyms of D. rumecicola (Hori, 1935). D. emicis (Mimeur, 1935) is downgraded to a subspecies of D. rumecicola. Keys to species of the genus Dysaphis living on plants of the family Polygonaceae are provided.

New Boraginales from tropical America 8: Nomenclatural notes on Varronia (Cordiaceae: Boraginales)

A review of the species of the neotropical genus Varronia (Cordiaceae: Boraginales), for several floristic projects and the preparation of a treatment for the Online World Flora, reveals several nomenclatural issues, which include four new combinations and a nomen novum for one additional species.     

Taxonomic and nomenclatural changes in euantennariaceous sooty moulds: Ten new combinations in Euantennaria for species of Antennatula

The correct type species of Antennatula Fr. ex F. Strauss 1850 was quite recently considered to be Antennularia ericophila (Link) Höhn., not Antennatula pinophila (Nees) F. Strauss, and currently the illegitimate name Antennatula is regarded as a synonym of Metacapnodium Speg. 1918 (Metacapnodiaceae). Among Euantennaria Speg. 1918 and competing synonymous generic names Aithalomyces Woron. 1926, Phaeocapnis Cif. & Bat. 1963, Hormisciella Bat. 1956, and Hormisciomyces Bat. & Nacim. 1957, Euantennaria is adopted. As a consequence, with the change to one scientific name for pleomorphic fungi, the following 10 new combinations in Euantennaria (Euantennariaceae) for species of Antennatula sensu or used by Hughes are herein proposed: Euantennaria atra, E. cubensis, E. dingleyae, E. fisherae, E. fraserae, E. katumotoi, E. lumbricoidea, E. pinophila, E. shawiae, and E. triseptata. The respective brief notes for these species are also provided.     

Family Linoproductidae Stehli, (Brachiopoda) from the Upper Moscovian of the Middle Carboniferous of the Moscow Region

Species from the family Linoproductidae sensu str. from the Podolskian-Myachkovian deposits of the Moscow Region are revised and redescribed. The peculiarities of the arrangement of spines on the ventral valve are used as a basis for a new taxonomic structure. A new genus Linipalus, which appeared in the Podolskian time and was widespread in the Late Carboniferous and Early Permian, is established. Three new species of the genus Linispinus Lazarev, 2006, and one new species of the genus Linipalus gen. nov. are described.     

A new genus and species in the mite family Eupodidae (Acari,Eupodoidea) from Crimea

A new genus Pseudoeupodes Khaustov, gen. n. and new species Pseudoeupodes porosus sp. n. are described from moss in Crimea. The taxonomy of the Eupodidae and some other families and genera of Eupodoidea is reviewed. The genus Turanopenthalodes Barilo, 1988 is transferred from Penthalodidae to Penthaleidae. The family Cocceupodidae Jesionowska, 2010 and the genus Filieupodes Jesionowska, 2010 are considered as junior synonyms of Eupodidae Koch, 1842 and Cocceupodes Thor, 1934, respectively. A key to genera of the family Eupodidae is provided.

First record of the family Bothrideridae (Coleoptera) in Korea represented by the wood-boring beetle ectoparasite,Dastarcus helophoroides

The ectoparasitic beetle, Dastarcus helophoroides (Fairmaire), was observed for the first time in Korea as a result of a study of the natural enemies of Monochamus alternatus Hope and M. saltuarius Gebler, the vector of the pine wood nematode (Bursaphelenchus xylophilus (Steiner & Buhner)). Diagnostic illustrations are provided and the biology and host range of D. helophoroides (Fairmaire) are reviewed.     

The Euscorpius tergestinus (C.L. Koch, 1837) complex in Italy: Biometrics of sympatric hidden species (Scorpiones: Euscorpiidae)

This work stems from the results of a recent phylogenetic investigation on the Euscorpius carpathicus species complex from the Italian peninsula (Salomone et al. 2004. Phylogenetic relationships between the sibling species Euscorpius tergestinus and E. sicanus (Scorpiones, Euscorpiidae) as inferred from mitochondrial and nuclear sequence data. In: Proceedings of the16th Congress of Arachnology, August 2-7, 2004, Ghent University, Belgium, 268pp.; Salomone et al. in prep.). Molecular investigation produced interesting and unexpected findings on the scorpion Euscorpius tergestinus (C.L. Koch, 1837). Both nuclear and mitochondrial sequence data provided evidence of substantial genetic differentiation in specimens identified as Euscorpius tergestinus according to recent taxonomical changes (Fet and Soleglad 2002. Morphology analysis supports presence of more than one species in the “Euscorpius carpathicus” complex (Scorpiones: Euscorpiidae). Euscorpius 3, 51pp.). These specimens clearly belong to two well-differentiated evolutionary lineages. Molecular results highlighted the need for a new morphological investigation. The present study undertook the morphological analysis of specimens belonging to both genotypes with the aim of identifying morphological characteristics able to discriminate between the two taxa. The analysis of trichobothria patterns, morphometric ratios, granulation patterns and the observation of the pectinal sensilla confirm the difficulty in distinguishing these two genotypes and the high polymorphism of the subgenus Euscorpius Thorell, 1876. The length of pedipalp segments and dorsal patellar spurs (DPS), as well as femur leg granulation, are the main diagnostic characters; other ratios together with body color also help to distinguish the different genotypes. This study confirms the presence in Italy of two different cryptic species belonging to the “Euscorpius tergestinus” complex. Euscorpius tergestinus is a reddish, slender euscorpiid with a large dorsal patellar spine (DPS). A darker and generally squat phenotype with a short DPS, which corresponds to Euscorpius carpathicus concinnus sensu Caporiacco (1950), is elevated to the species level: Euscorpius concinnus (C.L. Koch, 1837). These two species are sympatric in several Italian regions, and their distribution pattern is possibly determined by intraguild predaction interaction.     

A new sharpshooter genus for Sphinctogonia lingula Yang & Li (Hemiptera,Cicadellidae, Cicadellini) from China

A new genus, Sphinctogoniella, is described to accommodate Sphinctogonia lingula Yang & Li, 2002, its type species from China. Sphinctogoniella lingula (Yang & Li, 2002), comb. n. is re-described and illustrated. Differences between the new genus and Sphinctogonia Breddin, 1901 are tabulated.     

Phylogenetic position and virulence apparatus of the pear flower necrosis pathogen Erwinia piriflorinigrans CFBP 5888 as assessed by comparative genomics

Erwinia piriflorinigrans is a necrotrophic pathogen of pear reported from Spain that destroys flowers but does not progress further into the host. We sequenced the complete genome of the type strain CFBP 5888^T clarifying its phylogenetic position within the genus Erwinia, and indicating a position between its closest relative, the epiphyte Erwinia tasmaniensis and other plant pathogenic Erwinia spp. (i.e., the fire blight pathogen E. amylovora and the Asian pear pathogen E. pyrifoliae). Common features are the type III and type VI secretion systems, amylovoran biosynthesis and desferrioxamine production. The E. piriflorinigrans genome also provided the first evidence for production of the siderophore chrysobactin within the genus Erwinia sensu stricto, which up to now was mostly associated with phytopathogenic, soft-rot Dickeya and Pectobacterium species. Plasmid pEPIR37, reported in this strain, is closely related to small plasmids found in the fire blight pathogen E. amylovora and E. pyrifoliae. The genome of E. piriflorinigrans also gives detailed insights in evolutionary genomics of pathoadapted Erwinia.     

Proposed validation of the specific namescrenatus Bruguière, 1789, andrenggeri Oppel, 1863 (Class Cephalopoda,Order Ammonoidea) from the Oxfordian stage of the upper jurassic

Ammonites crenata Bruguière (1789) is one of the oldest species names used in modern ammonite taxonomy. This is a nomen dubium that is probably a synonym of what modern authors callCreniceras renggeri (Oppel 1863), a common species of the early Oxfordian.Ammonites crenatus Bruguière in Oppel (1863) is a stratigraphically junior taxon of the middle Oxfordian. Nevertheless, there is a possibility, however improbable it may be, thatAmmonites crenata Bruguière andAmmonites crenatus Oppel are synonyms. Therefore it is proposed here to retain the current usage of the namescrenatus Bruguière emend. d’Orbigny (1847) andrenggeri Oppel.     

Reconstruction of phylogenetic relations of Ponto-Caspian gobies (Gobiidae, Perciformes) based on mitochondrial genome variation and some problems of their taxonomy

Phylogenetic relations of Ponto-Caspian gobies in the context of different taxonomic hypotheses have been studied based on the analysis of variations in cytochrome b gene. Evidence for the paraphyly of the genus Neogobius sensu lato, represented by two independent phyletic lineages that should be treated as separate genera Neogobius s. stricto (includes a species group of N. melanostomus-N. fluviatilis-N. caspius) and Ponticola, has been provided. It has been demonstrated that the Racer goby N. gymnotrachelus refers to the latter genus. It is proved that the Grass goby Gobius ophiocephalus belongs to the genus Gobius s. stricto.     

Studies in the Capparaceae XXX: Capparicordis, a new genus from the neotropics

Capparicordis, genus novum is established for Capparicordis crotonoides, C. tweediana, and C. yunckeri, all new combinations here established for three former species of the New World Capparis, Sect. Colicodendron. The first two are xerophytic shrubs or small trees easily separated by flower color, and the last is a grapple-hook scrambler of which flowers are unknown. They have allopatric distributions: C. crotonoides is found in Peru and Ecuador west of the Andes, C. tweediana from Argentina to Bolivia and Paraguay east of the Andes, whereas C. yunckeri is a rare, local endemic from the arid woodlands near Coyoles in northern Honduras. All have stellate pubescence, broadly cordate to subrotund-reniform leaves with (sub)palmate venation at the leaf blade base; a valvate calyx with closed aestivation; baccate subspherical fruits dehiscent by 2–4 valves (indehiscent in C. yunckeri?); cochleate-reniform seeds surrounded by a pulp-derived sarcotesta densely infiltrated by unbranched, unicellular hairs from the testa; and snow-white embryos. Capparicordis crotonoides has n=8 chromosomes.
