“…The development of pictorial keys can be a tool to assist the description of species and facilitate the understanding of the characters described textually (Pimpão & Mansur, 2009). Furthermore, their use facilitates the identification of species, allowing reliable identifications by students and researchers unfamiliar with a particular group (Oliveira, Mianzan, Migotto, & Marques, 2007). Thus, this study aimed to provide the first list of testate amoebae of the Paranoá Lake and develop a pictorial key to the taxa of Arcella recorded in this environment.…”

The pictorial key contributes to taxonomic analysis, as it lists the species found in a given environment, and points out the morphological characteristics that differs one specific taxon from the others. Arcellidae Ehrenberg, 1830 is one of the testate amoebae families with highest representativity in terms of richness and abundance, including three genera, that Arcella shows greater dispersion in different types of aquatic biotopes. The zooplankton community in the Paranoá Lake has been extensively studied over the decades. However, there are no studies on testate amoebae in this environment. The study aimed to develop a pictorial key to help in the identification of Arcella in the Paranoá Lake. Samples were taken with plankton net at 13 sites in the littoral zone of the lake. The elaboration of the key was based on morphological characteristics of the shell and pseudostoma of the individuals. There were identified 23 taxa, 16 species and seven subspecies. Two species with low incidence in Brazil were recorded (Arcella catinus and Arcella rota). The species richness was higher than the records published to date in Brazil, thus demonstrating the relevance of the data and the applicability of this pictorial key in other studies both in the Paranoá Lake, as in other regions.

First record of a benthic ctenophore in the Mexican Atlantic:Vallicula multiformis(Platyctenida, Coeloplanidae)

Ctenophores are one of the least known invertebrate phyla in Mexico, especially the benthic forms in which studies are incomplete and infrequent, lacking information about their ecology and diversity. As part of the environmental monitoring project ‘Biodiversidad Marina de Yucatán’ conducted in the southern Gulf of Mexico and Mexican Caribbean Sea, the benthic ctenophore Vallicula multiformis (Coeloplanidae) was identified in association with green algae in the southern Gulf of Mexico, and on an autonomous reef monitoring structure in the Mexican Caribbean Sea. This finding represents the first record of the occurrence of a benthic ctenophore species in Mexican waters. We provide morphological characteristics of V. multiformis in both reef areas. Recording this species increases the known number of Mexican ctenophore fauna from 33 to 34 taxa and represents baseline information for the continuous study of the ecology and diversity of benthic ctenophores in Mexico.

“…A elaboração de chaves e guias de identificação torna-se necessária para estimular mais estudos nesta região. Uma chave, segundo Oliveira et al (2007), facilita a identificação das espécies, permitindo que estudantes e pesquisadores não familiarizados com um dado grupo possam fazer identificações confiáveis. Para algumas regiões brasileiras já existem chaves de identificação de bivalves de água doce: Mansur et al (1987) para as famílias e gêneros das regiões Sul e Leste do Brasil e Mansur & Pereira (2006) para espécies do Rio dos Sinos, Rio Grande do Sul.…”
