“…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).…”

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.

“…Among the bivalves, Diplodon suavidicus (Lea, 1856) has a wide distribution across the Amazon basin (Bonetto, 1967;Haas, 1932Haas, , 1969Mansur and Valer, 1992;Pimpão and Mansur, 2009). Although there is a wide distribution of molluscs in Brazil, there are few records of Nematodas using these organisms as hosts (Thiengo et al, 2000).…”

Hysterothylacium larvae (Nematoda, Anisakidae) in the freshwater mussel Diplodon suavidicus (Lea, 1856) (Mollusca, Unioniformes, Hyriidae) in Aripuanã River, Amazon, Brazil

Larvae of Hysterothylacium use various invertebrates as intermediate hosts. Definite hosts include fish, birds, reptiles or marine mammals. This study describes the occurrence of Hysterothylacium (Nematoda, Anisakidae) larvae parasitizing the pericardic cavity of Diplodon suavidicus (Unioniformes, Hyriidae) specimens collected in the Amazon basin, Brazil. This is the first record of this nematode parasitizing freshwater bivalves in South America. The high prevalence, medium intensity and medium abundance suggest that D. suavidicus acts as intermediate host for Hysterothylacium species in that environment.

“…5 mm long, only 18 embryos were found. The shell of the Contas specimens is inequilateral and modioliform (Figure 5j-m), similar to the shell of E. simoni, according to the illustrations of Simone (2006, page 304, figure 1069), although some specimens of this species can be more equilateral (Pimpão & Mansur 2009, page 399, figure 10). The color pattern of the Contas specimens (Figure 5j-m) is similar to the pattern of E. bahiensis (Spix, 1827), a species that occurs in the Northeast region (Simone 2006, page 302, figure 1060), but shows a more equilateral shell shape.…”

“…In Brazil, it is difficult to determine whether species are threatened, because of the scarcity of information about the structure and distribution of the communities (Mansur et al 2003). Furthermore, most studies on communities inhabiting running waters are concentrated in the southeastern (e.g., Giovanelli et al 2005, Vidigal et al 2005, França et al 2007) and southern (e.g., Pereira et al 2001, Pfeifer & Pitoni 2003, Rangel e Souza et al 2008 regions, and are relatively rare in other parts of Brazil (Midwest region: Martins- Silva & Barros 2001, Colle & Callil 2012North region: Jesus et al 2007, Pimpão & Mansur 2009). In the semiarid Northeast region of Brazil, such studies are practically nonexistent , Souza et al 2010, and malacological research deals, in general, with lentic settings such as reservoirs, "açudes" (small reservoirs) and small waterbodies, focusing on vector species of human diseases or on invasive species (e.g, Abílio et al 2006, Santos & Eskinazi-Sant'Anna 2010, Souto et al 2011.…”

An inventory of macroinvertebrates conducted in the Contas River basin in Northeastern Brazil found 13 species of freshwater mollusks. Most of the community was represented by pulmonate gastropods, including Physa acuta, Drepanotrema anatinum, D. cimex, D. lucidum, Biomphalaria straminea?, Gundlachia radiata?, G. ticaga and Hebetancylus moricandi; the prosobranchs Pomacea archimedis?, Melanoides tuberculata and Littoridina sp. were also found. Bivalves were less diversified, represented only by Pisidium pulchellum? and Eupera simoni?. The taxonomic composition and the small size of many species reflect the intermittent condition of the basin. Additionally, the occurrence of shells of five terrestrial species (Helicina angulata, Gastrocopta pellucida hordeacella?, Beckianum beckianum, Succinea sp. and Systrophiidae gen. et sp. indet.) in the rivers reflects the occasional heavy rainfalls and floods in the region. The invasive gastropod M. tuberculata was the most abundant and widely distributed species. All 13 species were found in the lower course, in the Atlantic Forest region, and most, but not all, were recorded in the upper course, in the Caatinga region. The distribution and the occurrence of the bivalve species exclusively in the Atlantic Forest region indicate that the locally higher annual precipitation provides favorable conditions for the survival of these mollusks, such as a more stable hydroperiod. Resumo: Treze espécies de moluscos de água doce foram encontradas em um inventário de macroinvertebrados realizado ao longo da bacia do Rio de Contas, no Nordeste do Brasil. A maioria da comunidade foi representada por gastrópodes pulmonados, como Physa acuta, Drepanotrema anatinum, D. cimex, D. lucidum, Biomphalaria straminea?, Gundlachia radiata?, G. ticaga e Hebetancylus moricandi, embora prosobrânquios, como Pomacea archimedis?, Melanoides tuberculata e Littoridina sp. também tenham sido encontrados. Bivalves foram menos diversificados, e foram representados por Pisidium pulchellum? e Eupera simoni?. A composição taxonômica e o pequeno tamanho alcançado por muitas espécies refletem a condição intermitente da bacia. Além disso, a ocorrência de conchas de cinco espécies terrestres (Helicina angulata, Gastrocopta pellucida hordeacella?, Beckianum beckianum, Succinea sp. e Systrophiidae gen. et sp. indet.) dentro dos rios reflete as fortes chuvas e inundações que ocorrem ocasionalmente na região. O gastrópode invasor M. tuberculata foi a espécie mais abundante e bem distribuída. Todas as espécies foram encontradas no curso inferior, na região da Mata Atlântica, e a maioria, mas não todas, foram registradas no curso superior, na região da Caatinga. Esta distribuição e a ocorrência das espécies de bivalves exclusivamente na região da Mata Atlântica indicam que a maior precipitação anual desta região fornece condições favoráveis para a sobrevivência destes moluscos, como um hidroperíodo mais estável. Palavras-chave: Região Neotropical, Mata Atlântica, rios intermitentes, moluscos invasores, Bahia.
