On the occurrence of testate amoebae (Protozoa, Rhizopoda) in Brazilian inland waters. V. Families Hyalospheniidae, Plagiopyxidae,

ABSTRACT. This paper intends to be a contribution on the occurrence and geographical distribution of testate amoebae (Protozoa, Amoebozoa, Rhizopoda) in Brazilian inland waters, specifically the families Hyalospheniidae, Plagiopyxidae, Microcoryciidae, Cryptodifflugiidae, Phryganelidae, Euglyphidae, Trinematiidae and Cyphoderiidae. Fifty-four infra-generic taxa have been recorded. The genera with the greatest number of taxa are Nebela (Hyalospheniidae), with 17 taxa, and Euglypha (Euglyphidae), with 14 taxa. Euglypha acantophora (Ehrenberg), E. cristata Leidy, E. laevis (Ehrenberg), E. strigosa (Ehrenberg), Trinema enchelys (Ehrenberg), T. lineare Pénard and Cyphoderia ampulla (Ehrenberg) are the species with the greatest number of records in Brazil. Some taxonomic information is also provided. Key words: aquatic protozoa, testate amoebae, geographical distribution, Brazil. RESUMO.
