Ants are among the most abundant organisms on Earth, being adapted for living on different solid surfaces. However, in some habitats, like riparian forests and flooded plains, water can be a constant obstacle, and overcoming this obstacle can be essential to determine the persistence of ants in such habitats. While most ant species avoid the water during a flood by foraging at higher elevations or climbing on trees, a few species developed ways to overcome this obstacle by swimming. Here, we report, for the first time, ants of the species Linepthema micans (Forel 1908) performing rafts. We observed 14 rafts in three consecutive days at approximately 1400 meters a.s.l. in Serra do Cipó, Brazil. Notably, this is the first record of ant rafting in tropical mountaintop grasslands, which are extreme habitats with shallow and sandy soils, and where small temporary water pools are extremely common in the wet season.

Rhynchotermes nasutissimus (Silvestri) is a leaf litter feeder species distributed through the Neotropical region. We found for the first time this species associated with rat carrion in an urban area of Brasília, Distrito Federal, Brazil. Ten soldiers and 36 workers were spread in the cavities and between internal leathers of the carrion’s dry remains of the animal that have been exposed during a week in the soil, in March 2012, at end of the wet season. We believe that this uncommon behavior may reflect a nutritional need. Primeiro Registro de Rhynchotermes nasutissimus (Silvestri) (Isoptera: Syntermitinae) Associado à Carcaça de Rato em Brasília, Brasil Resumo. Rhynchotermes nasutissimus (Silvestri) é uma espécie que se alimenta de folhas de serrapilheira, distribuída pela região Neotropical. Encontrou-se pela primeira vez esta espécie associada com carcaça de rato, em uma área urbana de Brasília, Distrito Federal, Brasil. Os dez soldados e 36 operários se encontravam dispersos entre as vértebras e restos secos do animal que foi exposto durante uma semana no solo em março de 2012, final da estação chuvosa. Acredita-se que este comportamento raro seja resultado de alguma deficiência nutricional.

In the present paper we report for the first time the presence of Gundlachia radiata (Guilding, 1828), in northwestern region (Jujuy province), Argentina. Adult and juveniles specimens of this freshwater limpet were collected in two temporary water bodies. This record represents the first report of this species in Argentina but also is the southernmost point of occurrence of G. radiata in South America. As a result, the distributional range of this species is increased and the species richness of Ancylidae in Argentina is incremented to a total of seven species classified in four genera.

A Helorid wasp, Helorus ruficornis Förster, 1856, is reported for the first time on Tahiti (Society Islands), which is also the first record of both Proctotrupoidea and family Heloridae in French Polynesia. The potential hosts of Helorus ruficornis in French Polynesia are discussed.

   The Ciliophoran Trichodina magna Van As and Basson, 1989 is recorded for the first time in in Iraq from gills of the blue tilapia Oreochromis aureus (Steindachner, 1864) Iraq from Al-Graiat location on the Tigris River at Baghdad city. The description and measurements of this external parasite as well as its illustrations are given.

Euastrum lacustre is reported for Russia for the first time. This alcaliphilic species was found in the periphyton and plankton of three lakes in the Kursk Region (European Russia). A description of morphology, including the relief of cell wall, and habitats where this taxon is found are represented. LM and SEM microphotographs are provided. Morphological differences of E. lacustre from similar species are discussed. New species for region, namely Closterium aciculare, Cosmarium formosulum, C. granatum, C. pseudoinsigne, C. reniforme and Staurastrum pingue, are found in the samples together with E. lacustre.

Nodosilinea epilithica Perkerson et Casamatta is reported for the first time for Russia. The sample was isolated from a typical chestnut soil in the zone of dry steppes (Volgograd Region) and its identity was confirmed by morphological and molecular analyses. The specific feature of the studied strain is its ability to form nodules at normal (60–75 μmol photons ∙ m-2 ∙ sec-1) light. The number of nodules is supposed to be related to the age of a cyanobacterial culture.

Until recently only two species of Gyalideopsis (G. piceicola and G. alnicola) were known from very few localities in Russia. Gyalideopsis helvetica is reported for the first time for Russia from the southern part of Baikal area (KhamarDaban Range, Baikalsky Zapovednik). Description of the collected specimen and its comparison with the literature data are provided; morphology, ecology and distribution of G. helvetica are discussed. The hyphophores of G. helvetica are recorded and described for the first time. An identification key to Gyalideopsis species known in Russia is provided.

The parasitic louse fly Ornithomya comosa (Austen, 1930) (Diptera, Hippoboscidae), known from the Oriental Region (India, Thailand, Nepal and Peninsular Malaysia) and Asian part of the Palaearctic Region (Kazakhstan, Kyrgyzstan, West Siberia of Russia and Japan), is found for the first time in Europe and in the western part of Russia (Curonian Spit). Flies were collected from the swallow species Hirundo rustica (Linnaeus, 1758) and Delichon urbica (Linnaeus, 1758) (Hirundinidae). Two possible narratives for the occurrence of this fly in Europe are discussed.
