Chirnyssoides está associado ás bordas anteriores e posteriores das membranas das asas de morcegos. Sua distribuição é restrita a alguns países da América Central e do Sul, principalmente devido á falta de estudos. O objetivo deste trabalho foi registrar Chirnyssoides amazonae emCarollia perspicillata no Estado do Rio de Janeiro, bem como apresentar uma lista de hospedeiros e localidades paraChirnyssoides. Onze fêmeas e 22 aglomerados de ovos deC. amazonae foram colhidos em 11 indivíduos de C. perspicillata capturados na Reserva Biológica do Tinguá, utilizando redes de neblina. Na literatura encontramos 69 registros deChirnyssoides. Para o Brasil há relatos deChirnyssoides caparti, Chirnyssoides amazonae, Chirnyssoides brasiliensis eChirnyssoides phyllostomus. Este estudo relata o primeiro registro de Chirnyssoides amazonae no Rio de Janeiro e o segundo para o Brasil expandindo sua distribuição para o sul. Em C. perspicillata há registros de C. amazonae eC. surinamensis, sendo o primeiro registro de C. amazonae em C. perspicillata no Brasil.

Chirnyssoides parasitizes the anterior and posterior edges of bat wing membranes. Possibly due to a lack of studies, its distribution is believed to be restricted to a few countries of Central and South America, but its actual range is probably wider. The purpose of this paper is to report the presence of Chirnyssoides amazonae on the bat Carollia perspicillata in the state of Rio de Janeiro, Brazil, and to present a checklist of hosts and localities for Chirnyssoides. Eleven females and 22 egg clusters of C. amazonae were collected from 11 individuals of C. perspicillata captured in Tinguá Biological Reserve using mist nets. Our search of the literature came up with 69 records of Chirnyssoides. There are reports ofChirnyssoides caparti, Chirnyssoides amazonae, Chirnyssoides brasiliensis andChirnyssoides phyllostomus in Brazil. This paper reports the first record of Chirnyssoides amazonae in the state of Rio de Janeiro and the second in Brazil, indicating that their known distribution extends to the south. There are records of C. amazonae andC. surinamensis parasitizing C. perspicillata, but this is the first record of C. amazonae on C. perspicillata in Brazil.

The life cycle of ear mites of the genus Raillietia Trouessart consists of egg, larva, proto-and deutonymph and adult. The proto-and deutonymph are free living, non feeding instars. The teneral adult is the transfer stage. The minimum period required for completion of the life cycle is approximately eight days.

In vivo flushing of the ear canals with 50 to 100 ml collected all larvae in 100% of infested cattle. All adult mites were collected from 22 ou 27 parasitized ears (81.5%). Both stages adult and larva were collected from 18 out 22 parasitized ears (82%). The technique is adequate as a measure of prevalence, incidence, density/intensity of infestation as well as in vivo diagnosis. No damage to the host ear has been noticed.
