Fourteen species of aphids (Hemiptera: Aphidoidea) are recorded as new to Saudi Arabia. These are: Aphis coreopsidis (Thomas, 1878); Aphis illinoisensis Shimer, 1866; Baizongia pistaceae (Linnaeus, 1767); Capitophorus elaeagni (del Guercio, 1894); Dysaphis plantaginea (Passerini, 1860); Eucarazzia elegans (Ferrari, 1872); Geoica lucifuga (Zehntner, 1897); Hayhurstia atriplicis (Linnaeus, 1761); Macrosiphoniella absinthii (Linnaeus, 1758); Macrosiphoniella sanborni (Gillette, 1908); Smynthurodes betae Westwood, 1849; Uroleucon cichorii (Koch, 1855), and Wahlgreniella nervata (Gillette, 1908).

Obrieniolus, a new monotypic genus of Naupactini (Coleoptera, Curculionidae, Entiminae) from the Peruvian Andes and its phylogenetic placement

A new monotypic genus of Naupactini (Coleoptera: Curculionidae), Obrieniolus del Río is described based on the new species Obrieniolus robustus del Río, endemic to Peru. This genus is easily recognized by the black, denuded and shiny integument, with imbricate microsculpture and the rounded body, with short, cordiform and moderately convex elytra. According to a cladistic analysis based on 69 continuous and discrete morphological characters, the new genus is the sister taxon of a group formed by Amitrus Schoenherr, Trichocyphus Heller, Amphideritus Schoenherr, Asymmathetes Wibmer & O'Brien and Galapaganus Lanteri. The paper includes habitus photographs, line drawings of genitalia, mouthparts, and other external features of taxonomic value, and a dichotomous key to the genera of Naupactini distributed in the South American Transition Zone.

Regulatory function of Thy 1 negative cells. II. Spontaneous release of enhancing product by B cells cultured in vitro

The supernatant from non-antigen- and non-mitogen-stimulated spleen cells, cultured for 2 days, is effective in augmenting the IgM primary antibody response to TD antigens. The IgM and IgG secondary response to TD antigens, as well as the IgM response to TI antigens is not affected. Neither T cells nor accessory cells seem to be responsible for the release of the enhancing product. The soluble factor described in this paper (i) is not a polyclonal activator of B cells, (ii) does not substitute for thymus-derived cell functions in the in vitro response to heterologous erythrocytes, (iii) does not promote the response to optimal and suboptimal doses of Con A. It modulates the antibody production only in conjunction with T cells and in the presence of macrophages. Studies carried out with mouse myeloma cell lines confirmed present results obtained with normal spleen cells. A soluble product which exhibits the biological activities ascribed to the BEF and which prevents the activation of T suppressor cells was produced by a B-cell clone that does not express immunoglobulin heavy or light chains (P. del Guercio, S. Brugère, and M. F. Poirier, Cell. Immunol., in press).     

A pair of new sister species of Loneura (Psocodea, 'Psocoptera', Ptiloneuridae) from Valle del Cauca, Colombia, representing a new infrageneric group

Two sister species of Loneura, from Valle del Cauca, Colombia, are here described and illustrated. They constitute a new species group that modifies the scheme of classification, proposed earlier for the genus by García Aldrete et al. (2011b). The new group is characterized by having the central sclerite of the male hypandrium with four posterior projections. A key to the males of Group II is included. The types are deposited in the Entomological Museum of the Universidad del Valle. Colombia may prove to be the most species rich area for Loneura.

Passiflora incarnata (Passifloraceae): A new fruit crop

Passiflora incarnata:A New Fruit Crop. Economic Botany 53(2): 161–176, 1999. Passiflora incarnata bears flavorful fruits consumed by past and present peoples, and this plant deserves greater use as a fruit crop. Native to southeastern North America, it is an herbaceous perennial vine which flowers and fruits over much of the growing season. P. incarnata is self-incompatible and usually pollinated by carpenter bees (Xylocopa spp.). Plants are functionally andromonoecious, and low resource status favors male flower production and thus reduces fruit set. The fruits contain many seeds, each surrounded by an aril holding edible juice, and this juice can be consumed fresh or used in processed products. Because it is a minor agricultural weed, P. incarnata should not be introduced into regions where it may naturalize. Polyploid hybrids of P. incarnata and the subtropical and tropical passionfruit, P. edulis, are also potential temperate fruit crops. Future research on P. incarnata should evaluate intraspecific genetic variation and performance in cultivation.

Passiflora incarnata (Passifloraceae): Un Nuevo Cultivo Frutal

Resumen  Passiflora incarnata (Passifloraceae): Un Nuevo Cultivo Frutal. Tanto historicamente como actualmente el consumo de la fruta Passiflora incarnata justifica su consideración como un cultivo frutal. P. incarnata es una liana herbácea perenne, indígena del sudeste de America del Norte, que produce fruta a lo largo de la temporada de crecimiento. P. incarnata es autoincompatible y, usualmente, polinada por abejas carpinteras (Xylocopa spp.). Estas plantas son funcionalmente andromonoícas. Niveles de recursos bajos favorecen la production deflores masculinas y reducen el nuúmero defrutos. Los frutos contienen muchas semillas, coda una de ellas rodeada por un aril con jugo comestible. Este jugo se puede usar tanto para productos naturales como procesados. Es importante evitar la introduction de P. incarnata en regiones donde se pueda aclimatar, ya que se comporta como una mala hierba. Es posible cultivar los híbridos de P. incarnata y P. edulis, la fruta depasión tropical y subtropical, en zonas templadas. Futuras pesquisas se deberían enfocar en la evaluación de la variación genética intraespecífica y su rendimiento como cultivo.

A new fish, Peristedion nesium (Scorpaeniformes: Peristediidae) from Isla del Coco, Costa Rica

Several expeditions in recent years to Isla del Coco have increased the total number of species of fishes known from the island. Several of these species have been described as new endemics (Bussing 1983, 1990, 1991a, 1991b, 1997). During the 1972 R/V Searcher Expedition to Costa Rica several trawl collections were made around Isla del Coco. At five localities in depths between 110 and 180m, 86 specimens of a new species of Peristedion were taken and are described herein. A key to the four species of Eastern Pacific Peristedion is included.
