A Brazilian Porcupine, Coendou prehensilis (Linnaeus, 1758), was encountered and photographed at night on a recently cleared forest path in Presidente Hayes Department, Paraguay. Although C. prehensilis is widespread and has been reported from a variety of ecoregions and habitats, this record in western Paraguay is the first from the South American Humid Chaco ecoregion.

Abstract Remains of teiids assignable to the Tupinambinae (Tupinambis sp. or Crocodilurus sp.) are here described from the middle Miocene Collón Curá Formation at Cañadón del Tordillo, in Neuquén province, Argentina. No tupinambine species presently inhabits the region of the fossil locality. The fossils represent the westernmost distribution of fossil tupinambine teiids in Patagonia, enlarging the known geographical distribution of the teiids through the Miocene in a longitudinal range. Also, they constitute the first record of lizards from the Colloncuran SALMA, partially filling the record of tupinambine teiids for the South American Miocene.

Priogymnanthus colombianus, a new species and the first record of the South American genus of Oleaceae for Colombia is described and illustrated also we present a dichotomic key for the known species of genus. The new species differs from the three knowns for Priogymnanthus by: leaves oblong or oblong-elliptic, completely glabrous, petioles 10–17 (19) mm; inflorescences 15–20 (25) mm in length, with glabrous rachis, anthers about 3 mm length; fruits (10) 12–15 mm in diameter. P. colombianus occurs on premontane and dry forest in Colombia between 719 and 1213 m of elevation. Based on general threats to its ecosystems and few records found, we categorize the species as EN (endangered) following IUCN criteria.

Animal species have evolved a remarkable diversity of defensive phenotypic strategies aimed to deceive predators and other forms of danger. By relying on deception, these adaptations increase the chances of avoiding physical contact that may otherwise have very high fitness costs. One such deceptive behaviour is the popularly-known neck flattening, or “hooding”, observed in some snakes. Hooding consists in the lateral expansion and dorso-ventral flattening of the neck, which creates the impression of a bigger opponent during confrontations. This trait is highly characteristic of cobras (Elapidae family). However, neck flattening is not exclusive to elapids, and has in fact been observed in a few other snake lineages, including some species of the families Lamprophiidae and Colubridae. Here, we present the first report of hooding behaviour in the South American colubrid genus Philodryas, based on field observations conducted on the Chilean species P. chamissonis (the long-tailed snake). Our report adds to the few cases in which this deceptive behaviour has been observed in snakes outside the cobra family.

In mid autumn 1992 the South American leaf-miner Liriomyza huidobrensis (Blanchard) was firstly recorded on greenhouse cucumbers, melons, beans and outdoor beans, broad beans and lettuce in the following locations of Crete: 1) Mires, Tymbaki, Antiskari at Messara valley of Southern Crete 2) Filissia in the midland and 3) Platanias and Kokini Chani in Northern Crete. The following year L. huidobrensis had spread all over Crete (Ierapetra, Stomion, Koutsoura, Chania etc.) while melon and potato leaves which were sent to our laboratory from mainland Greece, Pirgos (Peloponissos) and Chalkida (Evia island), were found heavily damaged by the same leafmincr. The different types of mines (it usually mines the leaf alongside the veins), the colour of pupae (blackish) and the sudden attack of some plants (lettuce, broad beans, onions) which have never been damaged by the known local leafminers as yet, indicated that it was a newly introduced species. The new leafminer alerted the growers due to the high crop losses on outdoor and greenhouse vegetables (lettuce, broad beans, beans etc) despite the frequent application of registered insecticides. In the following year an extensive survey started to investigate its distribution and host plant in the greenhouses and outdoor vegetables and ornamentals in Crete. L. huidobrensis, a quarantine insect, is a polyphagous leafminer distributed in most biogeographical regions. It is native in South American countries from which it was spread soon in North America, Asia and Europe. In Europe it was first noticed in Holland, England and France in 1989 causing considerable damage to vegetables and ornamentals. It mines the spongy mesophyll reducing the photosynthesis more than the other leafminers. This type of mines is not easily visible, unless the leaf is observed through transmitted sunlight or artificial light. This method was applied to ensure accurate detection of larvae and their parasitoids under a stereoscope. In our observations we found mines in leaves and cucumber fruits as well. Studies of its life cycle on greenhouse beans and melons revealed that most pupae (98%) remain on the bean leaves outside a hole in the autumn, while a few fall on the ground. The number of pupae collected from ten leaves per 24h was: 5.7±1.6 on lettuce, 17.07±4.1 on beans, 24.2±7.3 on melon, 6.0±2 on broad bean leaves. During the survey the following host plants were recorded: Chemical control could be effective by applying certain insecticides (abamectin, triazophos, imidacloprid, heptenophos etc.) while biological control seems to be rather effective by the known parasitoids, which are already used against the tomato leafminer Liriomyza bryoniae Kalt. Biological control of L. huidobrensis was effective on lettuce by means of repeated releases of Dacnusa sibirica Telenga and Diglyphus isaea (Walker) but so far native parasitoids proved to be able to control the pest. Mass trapping with coloured sticky traps seems to be also a potential method in IPM programmes. The mortality of pupae collected from heavily treated greenhouse plants with insecticides varied from 65 to 74% while that of untreated plants was between 18-25%. No pupal parasitoids were recorded but D. isaea and D. sibirica were both recorded as larval parasitoids. D. isaea was abundant all over the year while D. sibirica only in spring-summer period. These two parasitoids were able, in certain cases, to control sufficiently the leaf miner in untreated greenhouse cucumber and bean plants. The neem seed extract (Azadirachta indica) applied on outdoor tomatoes in Antiskari (Southern Crete) proved harmless both on hymenoptera and on the mirid predator Macrolophus caliginogus Wagner. Despite its weak larvicide action on L. huidobrensis it was very effective in conjuction with parasitoids consisting of a promising candidate in IPM programmes.

The descriptions and illustrations of two new species of Podonomus, P. tehuelche and P. quinquesetosus are presented. Both species belong to the Brundin’s decarthrus group and were collected in an "orogenic island", representing the first record of a named Podonomus species from Argentina outside the Andean-Patagonian region. Immatures and adults were collected at relatively low altitude for the genus (500 to 800 m a.s.l.). A key for the South American male adults and pupae of the decarthrus group is presented.

A New Species

The genus Megarthrus Curtis 1829 with about 139 species described around the world, is the largest of the subfamily Proteininae (Coleoptera: Staphylinidae) (Cuccodoro 2011). Megarthrus is distributed worldwide (Cuccodoro 1999) but it is apparently more diverse in the Holartic region (Navarrete-Heredia et al. 2002). However, the South American fauna is underestimated because many of the collected specimens are not yet described (Cuccodoro 2011). Newton et al. (2005) cited the genus as probable in Colombia because some species are known from Central America and northern South America, but until now, no species has been published from Colombia. Therefore, M. andinus sp. nov. represents the first record of the genus and subfamily for this country.

We report a new record for the South American coati, Nasua nasua (Linnaeus, 1766), based on a specimen from Sierra de Perijá, Zulia state, western Venezuela. This specimen represents the first record of the species for the state, increasing to 192 the number of mammals reported for Zulia. It also extends the species distribution in about 245 km northwest from the nearest known locality in Venezuela, and about 80 km from the nearest locality in Colombia.
