A New Species

A new species of the genus Corythucha, C. bonaerensis n. sp., is described along with its egg and all immature stages. It was found in the province of Buenos Aires (Argentina) feeding on Quercus robur, its host plant. Comments on the life history of C. bonaerensis are provided together with photographs, and illustrations. The main differences with the other South American species, and other Corythucha species that feed on Quercus worldwide, are also discussed.

A New Species

Steleops buitrerensis n. sp. is here described and illustrated; it constitutes the 14 th species known in the genus, the 12 th known in the neotropics, and the first in the genus to be recorded in Colombia. The forewings and antennae are sexually dimorphic, and the head pattern of coloration, as well as the genital structure, separates it from the other described species. The location of the types is indicated in the description, and a key is included to separate it from the other South American species. S. pulcher New, previously known only in Mato Grosso, Brazil, is here recorded in Colombia.

The South American species of Desmarestia are revised using morphological features of field sporophytes and reproductive and ontogenetic characters obtained from laboratory culture of gametophytes and young sporophytes. Ten entities including a new species are recognized: D. chordalis, D. confervoides comb.nov., D. distans, D. firma, D. gayana, D. ligulata, D. muelleri sp.nov., D. patagonica, D. peruviana, and D. tropica. Although the taxa were distinguished in part using features of the life history in culture, most field thalli can be identified using morphological characters. A key to the South American species of Desmarestia is provided. Key words: culture study, Desmarestia, Desmarestia confervoides comb.nov., Desmarestia muelleri sp.nov., Phaeophyceae, South America, taxonomy.

A New Species

A new species of Chysis sect. Chysis is described from the Central-West region of Brazil. It is similar to C. aurea and C. bruennowiana, the other two South American species of the genus, but differs in the pale pink perianth with magenta stripes or dots on the labellum and on the abaxial surface of the column, and by a labellum that is wider than long with the mid-lobe not surpassing the length of the lateral lobes. The species, which confirms the presence of the genus in the Brazilian plateau, had been previously misidentified as C. laevis. Photographs, an illustration, and a key to the South American species are provided.

AbstractParagordius is a genus of Gordiida with a worldwide distribution, but with a scarce specific diversity. Sixteen species of the genus Paragordius have been described so far. In many cases, as with the other genera of Gordiida, the original descriptions of the species are insufficient due to the limitations of the techniques employed. In this work the holotypes of P. minusculus and P. esavianus are redescribed by scanning electron microscopy (SEM), a new species of Paragordius is described, the distribution for P. esavianus and P. varius is enlarged and a new host record of P. esavianus is presented.

Average Adult

Material collected in Loch Tannoch was allowed to macerate in a chemical nutrient. A rich crop of Euglena gracilis as well as other infusoria resulted. Eight months later, when the Euglena had encysted, many amoebae were found at the bottom of the receptacle. They constitute a new species, here named Amoeba hugonis. An average adult specimen, when extended, measures about 104x52·2µ. The nucleus consists of a central karyosome lying in the nuclear sap, separated from the cytoplasm by a wellmarked nuclear membrane. Between the latter and the karyosome is situated an achromatic ‘collar’ with chromatin particles embedded in it. Fission is described, but a study of mitosis has been deferred. The life-history of this small amoeba is very similar to that of the large A. proteus, &c. The cycle occupies two months. Chromidia begin to appear in the cytoplasm of the early adult. They give rise to spores, out of which amoebulae hatch.

A New Species

Hysterionica s.l. (including Neja) comprises ca. 15 species distributed mainly in the grasslands of southern Brazil, Uruguay, central and northern Argentina and Southern Paraguay. Based on field surveys, study of nomenclatural types and other specimens, and review of literature, a new species is proposed here, Hysterionica chamomilloides, endemic of mountainous regions of northern Uruguay, and southwestern Rio Grande do Sul state, Brazil. This work provides a detailed morphological description of the new species, information on its geographic distribution, habitat, phenology, conservation status, and discusses the main differences between H. chamomilloides and the morphologically most similar species. Illustrations, images and a key to the South American species of Hysterionica are also supplied.

During the course of an extensive survey of Coleoptera from tropical southern Florida, a specimen of the exclusively Neotropical genus Dryocoetoides was found in flight intercept traps (Atkinson and Peck, 1994; Peck, 1989).  Over the intervening years I have had the opportunity to compare the specimen with material in the U.S. National Museum  and in the S. L. Wood collection (recently transferred to the USNM).   Wood's ( 2007) recent monograph of the South American species of Scolytinae included a key to all the known species of the genus, not only those known from South America.  Based on that key and included descriptions I was able narrow down the possibilities and to borrow selected Schedl types from the Naturhistorisches Museum Wien.  As a result, I have reached the conclusion that this specimen represents an undescribed species.  It is described here to make the name available for a regional monograph of the bark and ambrosia beetles of the southeastern U.S. (Atkinson, in prep.).

A half a century ago, R. T. Leiper described a new species belonging to the genus Fasciola from specimens which he collected from hippopotami at the Murchison Falls, on the Victoria Nile in Uganda, in the summer of 1907. This species, Fasciola nyanzae, was found in the bile ducts of the liver, and in most instances the specimens were somewhat macerated owing to the length of time that had elapsed before the animal could be recovered from the water. Nevertheless, the characteristic shape of these liver flukes and the restriction of the branched testes to the anterior third of the body made it possible to recognise them as being different from all other species of the genus known at that time.

A New Species

Rheotanytarsus is a speciose genus, currently composed by more than 100 nominal species distributed worldwide, 19 are known from the Neotropical region, four from South America and only one is registered for Peru. In the present study, a new species is described and illustrated based on males collected in the Peruvian Andes. In addition, the key to the South American species is updated and a distribution map of them is provided. Rheotanytarsus amaru sp. n. is easily distinguished from the congeneric species by the dark general coloration and the hypopygial morphology.
