RESUMO
The family Leeuwenhoekiidae has a worldwide distribution. In Brazil, it is represented by five genera and 10 species parasitising all groups of terrestrial vertebrates. Examination of material housed in the Acari Collection of the Instituto Butantan revealed undescribed species belonging to this family. In the present study, we describe a new genus, Caramuruacarus gen. nov., with the type species Caramuruacarus carnavalesca sp. nov. from the Minas Gerais State and a new species for the genus Whartonia, Whartonia parauapebensis sp. nov., from Pará State, both from the soil of Brazilian caves. In addition, a discussion of the genus Whartonia and its subgenera is provided.

O exame do material alojado na Coleção Acari do Instituto Butantan revelou espécies não descritas pertencentes a esta família. No presente estudo, descrevemos um novo gênero, Caramuruacarus gen. nov., com a espécie-tipo Caramuruacarus carnavalesca sp. novembro do Estado de Minas Gerais e uma nova espécie para o gênero Whartonia, Whartonia parauapebensis sp. nov., do Estado do Pará, ambos do solo de cavernas brasileiras. Além disso, é fornecida uma discussão sobre o gênero Whartonia e seus subgêneros.
RESUMO
The genus Apolonia is only known from the single species, Apolonia tigipioensis Torres et Braga, occurring in Venezuela and northeastern Brazil. The larval stage is primarily a parasite of birds, but they may parasitize mammals, including humans. This species can cause nodular lesions in birds. In the present study, we are redescribing the species A. tigipioensis based on the slides deposited at the Acari Collection of the Butantan Institute. Furthermore, we designate a lectotype and paralectotype for this species.
RESUMO
In this article, we describe a new species of chiggers, Parasecia fernandae sp.n., and report the presence of Arisocerus hertigi (Brennan et Jones, 1964), Eutrombicula goeldii (Oudemans, 1910), Microtrombicula brachytrichia Brennan, 1971, Parasecia manueli (Brennan et Jones, 1960), Quadraseta brasiliensis Goff et Gettinger, 1989 and Serratacarus dietzi Goff et Whitaker, 1984, for the first time in Rio de Janeiro State. P. manueli is a new record for Brazil. All of these species of chiggers were found parasitizing Nectomys squamipes (Brants, 1827). Besides that, A. hertigi was found on Oxymycterus sp., and S. dietzi—on Cerradomys subflavus (Wagner, 1842).
