“…Since R. rattus has an opportunistic nidification (Coto 2015) and it could share some arboreal habits with O. longicaudatus (González-Ittig et al 2010; Coto 2015, we believe that this finding is accidental and R. rattus should not (Gettinger 1987; Lareschi et al 2004; Correia 2015; Gettinger and Owen 2016. Gigantolaelaps wolffsohni has been found in the others no Oryzomyini rodents such as Lundomys molitor (Winge), Akodon azarae Fischer, and Bolomys obscurus Waterhouse in Uruguay (Lareschi et al 2006), however, these authors found almost all the mites associated with Oligoryzomys rodents. Previously, G. wolffsohni was found on a single Abrothrix sanborni (Osgood) in Chile (Lareschi and González-Acuña 2010).…”

The Gigantolaelaps mites (Mesostigmata: Laelapidae) are easily recognized by their large size. In Chile, Gigantolaelaps wolffsohni is the only recognized species Gigantolaelaps and it has only been reported from four localities, always in association with Oligoryzomys longicaudatus. Our research study aimed to contribute to the severely limited information about the ecology and distribution of G. wolffsohni in Chile and determine whether factors such as season, ecological region and weight-and sex of the host influence the abundance of this mite. We captured and assessed 329 O. longicaudatus in different seasons and localities. We classified sampled localities as being part of the Mediterranean, Template Forest, or Magellanic Forest ecoregion due to reported genetic and morphological differences of O. longicaudatus between ecoregions. Information about the season, ecoregion, and weight and sex of the host were recorded during mite sampling. These variables were assessed to determine their influence on mite abundance and prevalence through negative binomial and logistic regression models. We found 19 new localities where G. wolffsohni is distributed in Chile. These mites displayed an aggregated distribution in all ecoregions. We found that biogeography, weight, and sex of the host are not related to the abundance and prevalence of G. wolffsohni. Nonetheless, we found a strong association between the season and the abundance and prevalence of mites. All mites found were females; additionally, we found larva stage inside some female mites. We discussed the relationship between different ecological aspects and the abundance and prevalence of ectoparasites. Also, we discussed the finding of the larvae of G. wolffsohni, which means that this specie is at least larviparous, and finally, we discuss the specificity of Laelapidae mites.

“…In Argentina and Uruguay, mites identified as A. rotundus were listed in association with the akodontine Deltamys kempi Thomas, 1919 (Lareschi andMauri, 1998;González and Pardiñ as, 2002;Lareschi et al, 2006). However, recent studies have concluded that mites associated with D. kempi in the basin of La Plata River in Argentina resemble A. rotundus but actually represent a new Androlaelaps species (Teta et al, 2007;Navone et al, 2009).…”

Androlaelaps maurii , a new species of laelapine mite, is described on the basis of female specimens collected from the pelage of the akodontine rodent, Deltamys kempi, from La Plata River basin in Argentina. Androlaelaps maurii can be differentiated from closely related species by its smaller size, the differing distribution of setae in the dorsal shield, and an unarmed opithogaster. This mite appears to be host specific to D. kempi and occurs on this rodent throughout its distribution in Argentina and Uruguay.
