Abstract The stump-tailed porcupine, Coendou rufescens, is a widely distributed but scarcely documented species inhabiting the Andean region of Colombia, Ecuador, Peru, and an isolated population in Bolivia. Despite the wide distribution different aspects on its biology and ecology are still unknown. We present an update to the distribution of C. rufescens, and recent observations on the anatomy, natural history, and conservation in Colombia. For this, we described the male genitalia and present data on reproductive periods, plants used and consumed, and threats. The distribution of C. rufescens comprises 12 ecoregions in an area of 376,225 km2 for the northern group (Colombia, Ecuador, and Peru) and 393 km2 for the southern group (Bolivia). The highest elevational record is in Ecuador (4387 m), being the porcupine inhabiting at highest elevations. The anatomy of the glans is similar to that observed in Coendou quichua and constitutes the second species of Coendou with available information on glans morphology. C. rufescens consumes fruits and leaves of potato cider (Sechium edule: Cucurbitaceae) and woody shrub (Bejaria: Ericacea), and usually perches even in exotic species such as pines. Finally, common treats for the species in Colombia are related to hunting pressures, predation by domestic dogs, and roadkills.

In northeastern Chihuahua and Trans-Pecos Texas, in the early Late Albian zone of Hysteroceras varicosum occurs the Boeseites romeri (Haas) fauna with B. romeri (Hass), B. perarmata (Hass), B. aff. barbouri (Haas), B. cf. howelli (Haas), B.proteus (Haas), Prohysteroceras cf. P. hanhaense Haas, Elobiceras sp., and Dipoloceras (?) sp. B. perarmata has also been collected at Cerro Mercado, near Monclova, Coahuila. Haas originally described this fauna from Angola. Now, from rocks in the same zone in the Sierra Mojada, Coahuila, Mexico, there is a form related to if not identical with Hysteroceras famelicum Van Hoepen, also originally described from Angola and also from the zone of Hysteroceras varicosum.These fossils are known only from southern North America and Angola; they have not been described from the European Tethys. In 1984 I suggested that during the highstand of sea level of the early Late Albian (Hysteroceras varicosum zone) these ammonites migrated from Angola to Mexico and Trans-Pecos Texas via an epeiric seaway extending across the sag between South America and Africa proposed by Kennedy and Cooper. This would be twelve to fifteen million years prior to an oceanic connection between the North and South Atlantic.I would now ask, can similar epeiric seas and highstands of sea level explain the migration of successive European, Tethyan, Jurassic ammonite faunas down the Mozambique Channel and around the horn of Africa into the Neuquen Basin of Argentina before Africa and Antarctica separated, as proposed by Spath.

The land snails of the family Amphibulimidae occurring within northwestern South America are critically examined and notes on their distribution are given. The total number of taxa discussed is 61 (7 Dryptus, 54 Plekocheilus); of these, four Colombian Dryptus and 32 Plekocheilus species are included. The following new species are described: Plekocheilus (P.) bigener, P. (P.) incognitus, Plekocheilus (Eurytus) camaritagua, P. (E.) labiosus, and P. (E.) paraguas. The following nominal taxa are now synonymized: Plekocheilus (P.) speciosus (Pfeiffer, 1854) = P. (P.) plectostylus (Pfeiffer, 1848); Plekocheilus (Eurytus) couturesi Ancey, 1900 = P. (P.) glandiformis (Lea, 1838); Plekocheilus (Aeropictus) latilabris (Pfeiffer, 1855) = P. (A.) succineoides (Petit de la Saussaye, 1840); Plekocheilus (Eurytus) virgatus (Pilsbry, 1935) = P. (E.) mabillei (Crosse, 1867) = P. (E.) pulicarius (Reeve, 1848). Also, Simpulopsis fulguratus Miller, 1878 is now considered a junior subjective synonym of Simpulopsis (Eudioptus) citrinovitrea (Moricand, 1836). For the following species, precise localities are given for the first time: Dryptus stuebeli (Martens, 1885), Plekocheilus (Aeropictus) cathcartiae (Reeve, 1848), P. (E.) cardinalis (Pfeiffer, 1853), P. (Eurytus) episcopalis auriformis (Da Costa, 1904), P. (E.) episcopalis corticosus (Sowerby, 1895), and P. (E.) lynciculus (Deville & Huppé, 1850). Newly recorded for the Colombian malacofauna are the following taxa: Plekocheilus (P.) couturesi (Ancey, 1900), P. (Eurytus) piperitus (Sowerby I, 1837). The following taxa are excluded from the Colombian fauna: Dryptus funckii (Nyst, 1843), Plekocheilus (Aeropictus) veranyi (Pfeiffer, 1848), Plekocheilus (Eurytus) jimenezi (Hidalgo, 1872).

In 1937-38 the Argentine Department of Agriculture initiated an exchange of grasshopper parasite material with the Canadian Department of Agriculture which was engaged in a study of the natural control of grasshoppers in various provinces of Canada. By 1942 it was considered desirable to introduce exotic species of parasites into Canada on as wide a scale as possible, and the temperate regions of South America were selected as being the most promising for a survey. The parts of the temperate zone of South America to which preferential attention was to be given included the countries of Uruguay, Argentina, and Chile. The well known grasslands of the Rio de la Plata area have been partially transformed into one of the world centres for cereal production and as in other parts of the world increased grasshopper populations constitute a major problem in the agriculture of the region. Here species of the genus Dichroplus are frequently pests in the way in which members of the closely related Melanoplus are in North America.

AbstractThe significance of the housefly, Musca domestica Linnaeus, as a probably introduced species in the Western Hemisphere is pertinent to a search for more exotic natural enemies in the Eastern Hemisphere. Avenues of entry into this hemisphere are discussed. A list is provided of the principal larval and pupal parasites found by the authors attacking M. domestica in North, Central, and South America and this is compared to species from the Eastern Hemisphere.

Brachylaimids are parasitic trematode fluke worms that have a terrestrial life cycle involving land snails and slugs as the first and/or second intermediate hosts for the cercarial and metacercarial larval stages. A wide range of mammals, birds, reptiles and amphibians are the definitive hosts for the adult worm. Brachylaima spp. have been reported from most continents including Europe, Africa, Asia, North and South America and Australia. There are over 70 described species in the genus with seven species indigenous to Australia. Although Brachylaima spp. are a cosmopolitan terrestrial trematode they have not been recorded to infect humans other than the three Brachylaima cribbi infections reported in two children and an adult from South Australia.

In May 2012 Rotuma Island, the main island of the remote Rotuma Group (Fiji), was surveyed to document the composition of the non-native land snail fauna and to investigate if populations of previously recorded native land snail species persist. From sampling at nine locations, twenty-one land snail species from eleven gastropod families were found. Of these, eight species are non-native and two of these Parmarion martensi Simroth, 1893 and Quantula striata (Gray, 1834) (Ariophantidae) are new records for the Rotuma Group. Ten of the 13 species of native land snails found — including the endemic partulid Partula leefi E. A. Smith, 1897 and the rhytidid Delos gardineri (E. A. Smith, 1897) — were detected only as empty shells. The native Ouagapia perryi (E. A. Smith, 1897) and the endemic Succinea rotumana E. A. Smith, 1897 and Sinployea rotumana (E. A. Smith, 1897) remain undetected on Rotuma Island since their first collection in 1897. The non-native, invasive predatory flatworm, Platydemus manokwari, was also found and represents a major threat to the island’s land snail fauna. This non-native species appears to be absent in many other parts of the Fiji Island archipelago and thus a re-evaluation of existing quarantine measures is required to address its potential spread to non-invaded areas. Comparisons with earlier surveys indicate a shift in the structure of the Rotuman land snail fauna over a 115-year period, with declining native components and increasing prevalence of non-native species. Further sampling, focusing on residual native habitat in less accessible areas such as coastal cliffs and offshore islets, is urgently needed to establish the conservation status of Rotuman native land snails and determine the threat posed by both, non-native snails and P. manokwari.

Commercial plant nurseries may serve as causes of dispersal of land snails and slugs (native and non-native) through the trade of plants and the related transport of eggs and small individuals that may pass unnoticed. Studies on the possible role of plant nurseries as a potential cause of dispersal of slugs in South America are lacking. To explore the role of garden centers, we collected and identified slugs in 12 commercial nurseries in two cities in the province of Buenos Aires, Argentina. Eight species of slugs were found. Based on our findings we validate the existence of Deroceras laeve and Belocaulus angustipes for Argentina and confirm the existence of Ambigolimax valentianus, which was recently cited for Argentina. We recommend that plant nurseries be regularly monitored given that snail and slug species are accidentally spread through trade in plants.
