Estudo dos ácaros (Acari: Mesostigmata: Spinturnicidae, Macronyssidae) ectoparasitos de morcegos (Mammalia: Chiroptera) no Brasil

Abstract

This study refer to the interaction of ectoparasites mites (Macronyssidae and Spinturnicidae) and their hosts bats in Brazil. These mites have a cosmopolitan distribution and are hematophagous. Also they show high degree of specificity with their hosts, suggesting cospeciation and cophylogeny. The first chapter of this research is a taxonomic catalog of macronyssids and spinturnicids species with their respective hosts in Brazilian collection site. Through literature review was presented a current overview about the distribution of these mites in Brazil. Chapter II reports for the first time, spinturrnicids mites in the states of Ceará and Mato Grosso. Specimens of bats and their ectoparasites were collected in areas of Caatinga and Pantanal biomes, the Private Reserve of the Natural Patrimony Serra das Almas and RPPN SESC Pantanal, respectively. In both areas was captured a total of 588 espinturnicídeos. The occurrence of Cameronieta Machado-Allison, 1965 genus and the species Mesoperiglischrus natali (Furman, 1966) as well as four new associations (Periglischrus iheringi Oudemans, 1902 - Chiroderma vizottoi Taddei & Lim, 2010; Periglischrus micronycteridis Furman, 1966 - Micronycteris sanborni Simmons, 1996; P. paracutisternus Machado-Allison & Antequera, 1971 – Trachops cirrhosus Spix 1823; Spinturnix americanus (Banks, 1902) - Myotis riparius Handley, 1960) are registered for the first time in Brazil. In chapter III is present a brief review of the taxonomic history of Cameronieta (Acari: Spinturnicidae), redefining the genus, and clarifying some questions that remain concerning the biology and systematic of the group. Were examined over 300 comparative specimens of Cameronieta Machado-Allison, 1965 in slides collections from Ceará (Brasil), Michoacan (México) and Falcon (Venezuela). Additionally, Cameronieta almaensis n.sp. is described on pteronotus parnelli (Gray, 1843) from the in Reserva Serra das Almas, northeastern Brazil, Ceará, Brazil.
