A new species of amphipod, Ptilohyale corinne sp. nov. (Hyalidae) is described from the Bahía Blanca estuary (38°53’S, 62°07’W) in Buenos Aires Province, Argentina. Ptilohyale corinne sp. nov. can be differentiated from its valid congeners by having two posterior marginal cusps on coxa 2 and 3, and asymmetrical telson lobes with a particular combination of setae: each lobe with three dorsal plumose setae and one seta on inner margin. This is the first record of Ptilohyale in South America. Additionally a key to the valid species of the genus is provided

First Time

Pteris cretica L. var. laeta is recorded for the first time in the Comechingones biogeographic province in central Argentina. This is the first record of P. cretica in central Argentina, and P. cretica var. laeta for the country. Until now Pteris cretica has only been known to occur, in America, in North America (Florida), Central America and South America in Neotropical biomes from Peru, Chile, Brazil, Paraguay, Uruguay and northern Argentina as established in the Yungas biogeographic province, and as ruderal in Buenos Aires. An updated description is provided, along with pictures, differences with P. cretica var. cretica, and characteristic of the novel habitat of the species.

Australapatemon canadensis Dubois and Rausch, 1950 (Digenea, Strigeidae) is reported parasitizing to Cygnus melancoryphus (Molina) (Anatidae) from Lacombe Lagoon, Buenos Aires Province and Pellegrini Lake Río Negro Province, Argentina. This species is described and compared with related species. The finding of A. canadensis in C. melancoryphus in Argentina represents a new host record extending to South America the geographical distribution of this species.

Blanca Estuary

Accelerator mass spectrometry (AMS) radiocarbon dates were obtained for 18 mollusk shells collected alive along the Buenos Aires province coast, Argentina, over the period AD 1914–1935. Reservoir ages were estimated for all samples on the basis of the tree-ring calibration curve for the Southern Hemisphere (SHCal04, McCormac et al. 2004) and the marine δR values calculated as the difference between the conventional 14C age and the age deduced from the marine, mixed-layer model calculation (Marine04, Hughen et al. 2004). For most coastal locations, a great δR scatter was observed, ranging from 191 to 2482 yr, which is explained by the input of varying content of dissolved carbonate by rivers and groundwater (“hardwater effect”) and indicates a serious limitation for shell-based 14C chronologies. Within the interior of Bahía Blanca estuary, δR values ranged from −40 to 50 ± 46 as a consequence of the local geological particularities of the environment. This suggests that, with some restrictions, the marine calibration curve with standard parameters (δR = 0) could be used at this location.

Deroceras reticulatum is a misanthropic European species spread widely throughout South America. At the moment this species is considered a 'pest' in direct sowing such as maize, soybean, sunflower, wheat, alfalfa and clovers, among others. The aim of this paper is to report the first record of D. reticulatum in the Reserva de Usos Multiples Isla Martín García, Buenos Aires province and to provide information about this species distribution in five Argentina provinces.
