Redescription of Apolonia tigipioensis Torres and Braga, 1938 (Trombidiformes: Leeuwenhoekiidae)

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.

Description of Parasecia fernandae sp.n. (Trombidiformes: Trombiculidae) and new records of chiggers from rodents in Rio de Janeiro State, Brazil

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).
