A systematic revision of Baconia Lewis (Coleoptera,?Histeridae,Exosternini)

Here we present a complete revision of the species of Baconia. Up until now there have been 27 species assigned to the genus (Mazur, 2011), in two subgenera (Binhister Cooman and Baconia s. str.), with species in the Neotropical, Nearctic, Palaearctic, and Oriental regions. We recognize all these species as valid and correctly assigned to the genus, and redescribe all of them. We synonymize Binhister, previously used for a polyphyletic assemblage of species with varied relationships in the genus. We move four species into Baconia from other genera, and describe 85 species as new, bringing the total for the genus to 116 species. We divide these into 12 informal species groups, leaving 13 species unplaced to group. We present keys and diagnoses for all species, as well as habitus photos and illustrations of male genitalia for nearly all. The genus now contains the following species and species groups: Baconia loricata group [Baconia loricata Lewis, 1885, B. patula Lewis, 1885, Baconia gounellei (Marseul, 1887a), Baconia jubaris (Lewis, 1901), Baconia festiva (Lewis, 1891), Baconia foliosoma sp. n., Baconia sapphirina sp. n., Baconia furtiva sp. n., Baconia pernix sp. n., Baconia applanatis sp. n., Baconia disciformis sp. n., Baconia nebulosa sp. n., Baconia brunnea sp. n.], Baconia godmani group [Baconia godmani (Lewis, 1888), Baconia venusta (J.

A new species of Alstroemeria (Alstroemeriaceae) from Pará, Brazil

A new species,Alstroemeria paraensis, from Pará, Brazil, is described and illustrated. This species is characterized by its robust floral stem, reduced leaves, congested inflorescence, and maculated inner and outer tepals.     

A new species of Anthodiscus (Caryocaraceae) from Chocó, Colombia

The first record ofAnthodiscus from the rain forest of Pacific coastal Colombia is the new speciesA. chocoensis which is described here. The distribution of the genus is discussed in relation to its recent discovery in both the Chocó and the coastal forests of eastern Brazil.     

A New Synthesis of (—)-exo-Brevicomin

Rubusoside derivatives by transgalactosylation of various β-galactosidases were isolated and their structures were analyzed. Escherichia coli β-galactosidase produced mainly 13-O-β-d-glucosyl-19-O-[β-d-galactosyl-(1→6)-β-d-glucosyl]-steviol (RGal-2). Bacillus circulans β-galactosidase produced mainly 13-O-β-d-glucosyl-19-O-[β-d-galactosyl-(1→4)-β-d-glucosyl]-steviol (RGal-1a) in the early stage of the reaction and then produced 13-O-[β-d-galactosyl-(1→4)-β-d-glucosyl]-19-O-β-d-glucosyl-steviol (RGal-1b). With decreasing the amount of these products (RGal-1a and RGal-1b), RGal-2 was produced.     

A Total Synthesis of (±)-Pachyrrhizone

We examined whether developing cotyledons of soybean seed had photosynthetic activities. The cotyledons evolved oxygen under illumination and the activity was inhibited by 3-(3′,4′-dichlorophenyl)-1,1-dimethylurea. The rate of oxygen evolution decreased during the development of seeds; about 30μ miol O₂ · mg chlorophyll^-1 · hr^-1 at the early developing stage and about 10μ miol O₂-mg chlorophyll^-1 · hr^-1 at the late developing stage. The rate of oxygen uptake remained at an almost constant level of 40^mol 0₂-mg chlorophyll^-1 · hr^-1 throughout the development. Photosynthetic ¹⁴CO₂-fixation by the cotyledon was observed. Ribulose bisphosphate carboxylase was immunochemically detected in the developing cotyledons. These results show that functional photosynthetic apparatus is present in the developing cotyledons of soybean seeds.     

A new species of Apechoneura Kriechbaumer (Hymenoptera, Ichneumonidae, Labeninae) from Colombia

A new species of the ichneumonid subfamily Labeninae, Apechoneura seminigrasp. n., is described. Specimens were collected from the Amazon Rainforest of Colombia.     

A new species of Kritskyia (Dactylogyridae,Ancyrocephalinae) parasite of urinary bladder of Prochilodus lineatus (Prochilodontidae,Characiformes) from the Floodplain of the High Paraná river,Brazil

A new species of Kritskyia inhabits the urinary bladder of the "curimba", Prochilodus lineatus in the floodplain of the high Paraná river. The new species resembles others members of Kritskyia in the following features: haptor lacking anchors and with 14 hooks marginal, posterior male copulatory organ non articulated with the accessory piece and vagina a sclerotized tube. However, it differs from the known species mainly by the shape of the copulatory complex. This is the third endoparasitic monogenean species reported from freshwater Neotropical fish.     

A Taxonomic Study of the Genus Alebroides Mats, from China(Homoptera, Cicadellidae, Typhlocybinae)

The genus Alebroides was established by Matsumura in 1931. As far asthe present authors have learned there are 7 species reported from Chinain previous works. They are listod as follows:     

Significance of each of three missense mutations, G484A, G667A, and G808A, present in an inactive allele of the human Lewis gene (FUT3) for α(1,3/1,4)fucosyltransferase inactivation

Recently, we found three novel missense mutations, G484A (Asp162Asn), G667A (Gly223Arg), and G808A (Val270Met), present in a Lewis-negative allele (le484,667,808) from an African (Xhosa) population. To define the relative contribution of each of the three mutations in the le484,667,808 allele for inactivation of the FUT3-encoded enzyme, we made chimeric FUT3 containing each of the three mutations. A transient expression study indicated that COS7 cells transfected with the FUT3 construct containing the G484A mutation expressed the Lewis antigen and had about 20% enzyme activity as compared with COS7 cells transfected with the wild type FUT3 allele, whereas COS7 cells transfected with the FUT3 construct containing either the G667A mutation or the G808A mutation did not express the Lewis antigen and showed no detectable (1,3/1,4)fucosyltransferase activity. These results suggest that the G667A and/or the G808A missense mutations of FUT3 alleles are responsible for the inactivation of the FUT3-encoded enzyme.     

A synoptic review of the Eocene (Ypresian) cartilaginous fishes (Chondrichthyes: Holocephali,Elasmobranchii) of the Bolca Konservat-Lagerstätte,Italy

Here, we review and discuss the records and taxonomy of the Ypresian (Eocene) chondrichthyans from the famous Bolca Konservat-Lagerstätte in northeastern Italy. Despite the outstanding diversity and the numerous studies focusing on the actinopterygian faunas from Pesciara and Monte Postale, the current knowledge about the systematics, taxonomy and phylogenetic relationships of the cartilaginous fishes from these Eocene sites remains elusive and largely inadequate. The celebrated Eocene Bolca Lagerstätte has yielded several exquisitely preserved articulated remains of chondrichthyan fishes in which delicate structures and soft tissues are preserved, as well as isolated teeth. The cartilaginous fish assemblage of Bolca comprises at least 17 species-level taxa belonging to 10 families in 6 orders, including selachians (Carcharhiniformes, Lamniformes), batoids (Torpediniformes, Myliobatiformes, Rajiformes) and holocephalans (Chimaeriformes). The occurrence of holocephalans represented by an isolated fin-spine of the chimeroid Ischyodus in the Bolca assemblage is reported here for the first time and represents the first record of chimeroids in the Eocene of Italy and also southern Europe. The Bolca chondrichthyan assemblage is remarkably different from those of other contemporaneous Boreal or Tethyan deposits, suggesting that its taxonomic composition is largely influenced by the palaeoenvironmental context. However, this synoptic review also highlights the importance of detailed revisions of all chondrichthyan remains from the Bolca Konservat-Lagerstätten.     

A new peirosaurid (Crocodilyformes) from the Late Cretaceous (Turonian–Coniacian) of Patagonia,Argentina

Peirosauridae is composed of mid- to large-sized terrestrial mesoeucrododylian crocodyliforms distributed throughout Gondwanan landmasses. Here we describe a new peirosaurid that comes from the upper levels of the Portezuelo Formation (Turonian–Coniacian, Upper Cretaceous) from Loma de la Lata, Neuquén Province, Argentina. This specimen consists of some associated bones belonging to a single individual. In order to facilitate comparisons, we recognise two different peirosaurid morphotypes based on skull shape: broad- and narrow-snouted taxa. The new taxon may be related to broad-snouted taxa, especially Gasparinisuchus peirosauroides. The new taxon here reported has strong heterodont dentition when compared with other peirosaurids. As in related forms, the fourth dentary tooth is caniniform, very large, acute and transversely compressed (much more than other peirosaurids), and the anterior dentary teeth have less globular, sharp serrated crowns. Large interalveolar spaces are present between both mandibular and maxillary teeth, a trait only observed on the new taxon. With this addition, we elevate the number of Patagonian peirosaurids to four. Moreover, it represents together with Lomasuchus palpebrosus the second peirosaurid species described for the Portezuelo Formation.     

A new species of Cuscuta (Convolvulaceae) from Michoacán, Mexico

A new species, Cuscuta cotijana, is described and illustrated from the Trans-Mexican Volcanic Belt in northwestern Michoacán, Mexico. The species is most closely related to Cuscuta jalapensis, C. mitriformis, C. rugosiceps and C. lindsayi, from which it differs by the large spur-like projections on the outer calyx lobes and the ovoid to conical capsule with a small intrastylar aperture.     

A revision of the genus Kaszabister Mazur (Histeridae, Histerinae, Exosternini)

We revise the four species of Kaszabister Mazur, 1972, one of which, Kaszabister barrigaisp. n., is described as new. The other species in the genus are Kaszabister rubellus (Erichson, 1834), Kaszabister ferrugineus (Kirsch, 1873) and Kaszabister carinatus (Lewis, 1888). The species are principally known from the subtropics of South America, with one in Central America. Lectotypes are designated for Kaszabister rubellus and Kaszabister ferrugineus, and a key is provided for all the species. Ants of the genus Solenopsis Westwood, mainly Solenopsis invicta Buren and Solenopsis saevissima (Smith), are documented as hosts of three of the four species.     

A new species of Phoenicopsis (Leptostrobales) from the Maastrichtian–Danian of Chukotka,Russia

A new species, Phoenicopsis anadyrensis Nosova, is described based on the leaf morphology and cuticle features from the Maastrichtian–Danian Rarytkin Formation, Chukotka, North-East of Russia. It is characterized by hypostomatic leaves with stomatal bands on the abaxial side, undulate anticlinal epidermal cell walls and papillae on the epidermal cells and on the subsidiary cells of the stomata. The new species is the youngest reliable representative of the genus Phoenicopsis. This record extends the stratigraphic range of Phoenicopsis from its previously known latest records in the early Campanian up to Maastrichtian–Danian. The persistence of the genus Phoenicopsis up to the Cretaceous–Paleogene boundary is most likely related with vicinity to mountain floras associated with Late Cretaceous and Paleogene volcanic uplands.     

A new species of Fuziidae (Insecta, Blattida) from the Inner Mongolia, China

A new species attributed to the genus Parvifuzia Guo & Ren, 2011, Parvifuzia peregrinasp. n., is described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. This new species, with apex of wing almost reaching the end of the abdomen and forewing venation with 30-32 veins at margin, broadens the diversity of Parvifuzia. This new species, with strongly curved cerci, could tightly clasp female and complete copulation more efficiently, same as other members of the family Fuziidae.     

A new species of Polypedilum (Uresipedilum) Oyewo & S?ther, 1998 from Zhejiang Province of Oriental China (Diptera,Chironomidae)

A new species of Polypedilum (Uresipedilum) Oyewo & Sæther, 1998, Polypedilum (Uresipedilum) minimum sp. n. is described as male. A key to adult males of the subgenus from China is presented.     

A new species of Phyllotis (Rodentia,Cricetidae, Sigmodontinae) from Tucumán province,Argentina

A new species of rodent of the genus Phyllotis is described based in cranial and external morphology, as well as morphometric data. Additionally, sequences of the mitochondrial gene cytochrome-b were used to asses the phylogenetic relationships. We have compared our specimens with all the extant species of the genus Phyllotis and also with some species of related genera, particularly with the most similar and with those that occur in the province of Tucumán and northwestern Argentina. The new species is large compared to the average size of the genus, and can be easily distinguished from all other species essentially by coloration and by cranial morphology. It is closely related to the recently described P. anitae, and these two species are, in turn, sister to P. osilae. The only two localities where the new species has been found are in the Upper Montane Forests of the southern portion of the Yungas Ecoregion, in the province of Tucumán, Argentina.     

A new species of Curimata (Characiformes,Curimatidae) from Paraná system,in resistencia,Argentine

A new curimatid fish, Curimata gnaca, from two localities, both in the neighborhoods of Resistencia, Chaco Province, Argentine, is described. The species is distinguished from other curimatids by the position of the mouth, a low number of perforated scales in lateral line, scales with straight margin on sides of body and long pectoral fins. The new species is placed in the genus Curimata until the problems within it will be solved.     

A cytogenetics study of Hydrodroma despiciens (Müller, 1776) (Acari: Hydrachnellae: Hydrodromidae)

The karyotypes of water mites (Acari: Hydrachnellae: Hydrodromidae) are largely unknown. The present investigation is the first report of a study designed to characterize the chromosomes of water mites. The study was carried out with specimens of Hydrodroma despiciens collected from Eber Lake in Afyon, Turkey. Several different methods were tried to obtain chromosomes of this species. However, somatic cell culture proved to be the most effective for the preparation of chromosomes. In the present study, we determined the diploid chromosome number of Hydrodroma despiciens to be 2n = 16. However, a large metacentric chromosome was found in each metaphase, which we believed to be the X chromosome. We could not determine the sex chromosomes of this species. This study is the first approach to the cytogenetic characterization of this water mite group. Furthermore, these cytogenetic data will contribute to the understanding of the phylogenetic relationship among water mites. To our knowledge, this is the first report on the cytogenetics of water mites.
