Oxymycterus wayku Jayat, D’Elía, Pardinãs, Miotti & Ortiz, 2008, a rodent species recently described, is known in only four localities within the Subtropical Mountain Forests of the Yungas eco-region in Tucumán, northwestern Argentina. Specimens were recorded in an owl pellet sample during a recent survey. This record represents the first for Oxymycterus in Catamarca Province, extending approximately 60 km south its southern distribution in the region. Sixteen other small non-volant mammal species were recorded there, turning this area into one of the most diverse for this understudied group in Argentina.

We report the first record of the genus Cavia and the species Cavia tschudii (Rodentia, Caviidae) in Catamarca province, northwestern Argentina, which represents a range extension of about 110 km southward for the species. The cranial and dental remains were recovered from an owl pellet sample found in eastern slopes of the Ambato range, at 1600 m elevation, in a highland grasslands-Chaco Serrano ecotone. According to the environmental continuity along the Ambato range, we suggest that the presence of C. tschudii in southernmost Catamarca and northern La Rioja province is likely.

Abrothrix jelskii is one of the lesser-known species in the genus Abrothrix, and it has only been recorded in a few localities in highland environments along the central Andean range. In Argentina, existing records are restricted to just one locality in Jujuy province. We have recently recorded this species in Salta Province, extending its known distribution 150 km northward in northwestern Argentina and 175 km further to the southeast compared to existing records from localities in southern Bolivia. Ten other rodent species were also recorded in the same area, with some of these records, such as those for Auliscomys sublimis, Akodon boliviensis, and Phyllotis sp., being noteworthy as well.

AbstractThe Silvery-brown Tamarin, Saguinus leucopus, is a primate species from the Callitrichidae family, endemic to Colombia, and that has very little ecological information. Here we report on a new dietary component for the species from Departamento de Caldas, Colombia, been the first record of S. leucopus predating an amphibian species (Phyllomedusa venusta). Despite some records exist about tamarin predation on amphibians, this is the first for this endemic species, and it is probably related with its foraging type. This record represents a noteworthy record and contributes to the knowledge of the natural history of this species. Key words: Andes, Callitrichidae, Colombia, Diet, Primates, Predation.Palabras clave: Andes, Callitrichidae, Colombia, Depredación, Dieta, Primates

Sigmodontine rodents are well represented in northwestern Argentina, but information regarding their distribution in La Rioja is scarce. We add new information for seven species from seven localities in the Famatina range. These new records were obtained using both captures and owl pellet analysis. We cite the first record of Neotomys ebriosus in La Rioja. The collection locality is unusual for this species because of its low altitude and xeric conditions. Other notable results include the second record of Abrothrix andinus and of the genus Oligoryzomys at the province.

Corbicula fluminea (Müller, 1774) is an Asian freshwater clam that is widely distributed throughout the world through multiple introductions. Its invasion can cause environmental and economic damage. In Brazil, C. fluminea is recorded in all major hydrographic basins. Here, we report the first record of C. fluminea in the Chapada dos Veadeiros region of Goiás, Brazil. This new record extends the known distribution of this species to a conserved area in the Cerrado biome, towards areas of interest for conservation and integral protection units of the biodiversity.

The genus Setodiscophrya Jankowski, 1981 has been previously recorded only from Germany, France, Russia, Ukraine and Japan. We provide the new record of Setodiscophrya steinii (Claparède and Lachmann, 1859) as an ectosymbiont of Ochthebius sp., in the province of Basilicata, Italy which represents the first record of the genus Setodiscophrya for Italy and the first worldwide record of S. steinii being associated to the coleopteran family Hydraenidae (Ochthebius sp.). The range distribution of S. steinii is expanded 900 km southwards.

Two new oversize troglobitic species of diplurans campodeids, Pacificampadaidarabotchi Sendra, sp. n. and Pacificampanipponica Sendra, sp. n., found in three caves in two southern Japanese islands are described. It is the first record of cave-dwelling Diplurans from Japan and more specifically these are two Campodeinae of Pacificampa Chevrizov, 1978 formally known in continental Asia with three cave-dwelling species described in Russia and China near the north of the Korean peninsula. In P.daidarabotchisp. n., in addition to its oversized body, the longest ever known in campodeids family, it shows as its main differential taxonomical feature the absence of lp metanotal macrosetae. P.nipponicasp. n. is much closer to continental Pacificampa species but it shows differences in the urotergal macrosetae formula. Both Japanese species have clear troglomorphic features related with their elongated body and appendages and an increase in number and complexity of the sensorial antennal equipment with unique olfactory chemoreceptors. Two biogeographical remarks are inferred: P.nipponicasp. n., has been found in two islands that were connected during the glacial age and P.daidarabotchisp. n. lives in a single cave near another where P.nipponicasp. n. dwells which allowing to suggest a sympatric distribution; Pacificampa seems to be related with Eumesocampa, a genus from North-America, as a consequence of the Holarctic connection between Asia and America. The interests of P.daidarabotchisp. n. and P.nipponicasp. n. as endemic species in addition to their biogeographical importance should be taken into consideration to ensure better management of the three touristic caves where they dwell and especially the protection of Mejido-do cave, the only location of the large P.daidarabotchisp. n. near to an active quarry.

Mydaea is a cosmopolitan genus of Muscidae (Diptera) poorly studied in the Neotropical region. In Argentina, only two endemic species, M. latomensis Snyder, 1957 and M. sexpunctata (Wulp, 1883) are known. This work provides the first country record for M. plaumanni Snyder, 1941, extending the known range of the species.
