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.

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.

Abstract Lagochilascariasis is a parasitic disease caused by nematodes of the genus Lagochilascaris. These parasites occur in the neotropical region and their definitive hosts are wild animals, domestic dogs and felids and, accidentally, humans. Here, infection by Lagochilascaris minor is recorded for the first time in a wild felid, in Brazil.

The chironomid diversity of Central America is virtually underestimated and there is almost no knowledge on the chironomid remains accumulated in surface sediments of lakes. Thus, in the present study we provide information on the larval sub-fossil chironomid fauna from surface sediments in Central American lakes for the first time. Samples from 27 lakes analysed from Guatemala, El Salvador and Honduras yielded a total of 1,109 remains of four subfamilies. Fifty genera have been identified, containing at least 85 morphospecies. With 45 taxa, Chironominae were the most specious and also most abundant subfamily. Tanypodinae with 14 taxa dominated in about one third of the sites. Orthocladiinae were presented by 24 taxa, but were recorded in 9 sites, being dominant in only one site. Podonominae were collected only in one locality. Head capsules of Heterotrissocladius found in the high elevation lake Magdalena, Guatemala, represent a first record for the Neotropical region. Both relative abundance and species richness of Chironominae and Orthocladiinae showed significant relationship to elevation, while Tanypodinae were indifferent. Hopefully, the list of taxa provided by our study will be a base line for future limnological and paleolimnological investigations using chironomid remains in the region.

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.

<p>As abelhas da subtribo Euglossina encontram-se amplamente distribuídas na região Neotropical, sendo mais diversificadas nas florestas úmidas. Objetivou-se realizar um levantamento das espécies desta subtribo em um fragmento de Mata Atlântica, um remanescente de brejo de altitude, localizado em uma região do Semiárido Brasileiro. O estudo foi conduzido no município de Portalegre, Rio Grande do Norte, entre os meses de fevereiro e agosto de 2015. A coleta de dados foi realizada mensalmente entre às 08h00 e 16h00, com a utilização de armadilhas contendo as essências eucaliptol, eugenol e vanilina. Foram coletados um total de 123 machos, distribuídos em quatro gêneros e seis espécies, sendo elas: <em>Eufriesea danielis </em>(43,09%), <em>Euglossa melanotricha </em>(25,20%), <em>Euglossa cordata </em>(15,45%), <em>Eulaema nigrita </em>(13,82%), <em>Euglossa fimbriata </em>(1,63%) e <em>Exaerete dentata</em> (0,81%). O intervalo entre 08h00 e 10h00 foi o de maior atividade, com 54,4% do total dos machos coletados. A comunidade de abelhas da região estudada apresentou maior preferência pelo eucaliptol, atraindo cinco espécies e 67 indivíduos (53,6%). A espécie <em>Eufriesea danielis </em>é reportada pela primeira vez para a região Nordeste do Brasil, enquanto que <em>Exaerete dentata </em>tem seu primeiro registro para o estado do Rio Grande do Norte.</p><p align="center"><strong><em>Euglossina (Hymenoptera: Apidae) fauna of a fragment of the Atlantic Rainforest of the Alto Oeste Potiguar, Rio Grande do Norte, Brazil</em></strong></p><p><strong>Abstract:</strong> The bees of the Euglossina subtribe are widely distributed in the Neotropical region, being more diversified in the humid forests.

Abstract Even though Colombia has high levels of ant species richness in the Neotropical region, this richness continues to increase. New records of the ant subfamilies Amblyoponinae, Dolichoderinae, Dorylinae, Myrmicinae, and Ponerinae are presented. Two species of Fulakora, two species of Azteca, one species of Cylindromyrmex, 25 species of Myrmicinae belonging to 12 genera (Acanthognathus, Basiceros, Daceton, Eurhopalothrix, Hylomyrma, Mycetomoellerius, Mycetophylax, Mycocepurus, Octostruma, Pheidole, Rogeria, and Talaridris), and one species of Leptogenys are registered for the first time for Colombia. Five species are new records for South America. For each species, the geographical distance of the record closest to the Colombian locality is offered. Several factors, such as access to previously unexplored conserved areas, sampling techniques that cover heterogeneous microhabitats such as leaf litter, and many more taxonomic researches have allowed the knowledge of ant fauna in Colombia to continue growing.
