Androlaelaps marmosops (Acari: Laelapidae), a new species associated with the mouse opossum, Marmosops incanus (Lund, 1840) in the Atlantic Forest of Rio de Janeiro State, Brazil

Abstract

Androlaelaps marmosops, a new species of laelapid mite, is described from the pelage of the mouse opossum, Marmosops incanus (Lund, 1840) (Mammalia: Didelphidae), in two areas of Atlantic Forest of Rio de Janeiro State. Measurements and illustrations are included for females only.

Host-ectoparasite specificity in a small mammal community in an area of Atlantic Rain Forest (Ilha Grande, State of Rio de Janeiro), Southeastern Brazil

“…Similarly, G. goyanensis, G. oudemansi and L. manguinhosi were strictly host specific. Mites identified as A. marmosops were represented by only two individuals is the new species described by Martins-Hatano et al (2001) from the same host species at Ilha Grande and Itatiaia (both in the state of Rio de Janeiro). The laelapine A. fahrenholzi had the most generalist association in the present study, occurring in all rodent host species captured.…”

Morphometric variations of laelapine mite (Acari: Mesostigmata) populations infesting small mammals (Mammalia) in Brazil

“…Previous studies focusing on ectoparasites of small mammals or in particular on laelapine mites, have described community composition and host associations in different areas and hosts of Brazil (Botelho and Williams, 1980;Linardi et al, 1984Linardi et al, , 1985Linardi et al, , 1991Gettinger, 1987;Barros et al, 1993;Martins-Hatano et al, 2000Bittencourt and Rocha, 2002;Bossi et al, 2002), or have described new species (Gettinger, 1992b(Gettinger, , 1997Gettinger and Bergallo, 2003). Morphologic variations among mite populations of different areas have rarely been studied (Gettinger, 1992a;Gettinger and Owen, 2000;Botelho et al, 2002).…”
