New records of Parvalona parva (Crustacea: Anomopoda: Chydoridae) from Brazil, with first description of the male Rev. Bras. Zool.
Elmoor-Loureiro,Lourdes M.A.; Santos-Wisniewski,Maria J. dos; Rocha,Odete.
The Neotropical species Parvalona parva (Daday, 1905) was previously reported only from two localities (Northern Argentina and Lençóis Maranhenses, Brazil). In the present paper, seven new records of P. parva from Brazil are presented. The specimens were collected from small waterbodies located in the Federal District and the states of São Paulo, Pará, and Pernambuco. These new records suggest that this species is not as rare as previously believed. The male, sexual female, and the lateral head pores of parthenogenetic females are described and illustrated for the first time.

Negreiros,Natalia F.; Santos,Renata M. dos; Oliveira,Laira Lúcia Damasceno de; Santos-Wisniewski,Maria J. dos; Rocha,Odete.
Populations of Synchaeta jollyae (Shiel & Koste, 1993) (Rotifera), a species recently recorded for the first time in Brazil and South America, were analyzed in reservoirs in Southeast Brazil. Sampling was carried out monthly from August 2006 to July 2007 at Furnas Reservoir in the Rio Grande basin, state of Minas Gerais, and in four cascade reservoirs in the Tietê River basin (Barra Bonita, Bariri, Ibitinga and Nova Avanhandava) state of São Paulo, in June and September 2008 and in January and May 2009. Synchaeta jollyae occurred in most samples and periods. From the results obtained it is evident that S. jollyae occurs in water bodies of varied trophic status but reaches larger populations in eutrophic water bodies and during lower temperature...
