Abstract

ON THE FAMILY Spinturnicidae OUDEMANS, 1902 AND ITS HOSTS IN BRAZIL, WITH A BIOMETRICAL STUDY OF Periglischrus iheringi OUDEMANS, 1902 AND OF Periglischrus ojastii MACHADO-ALLISON, 196 4 (ARTHROPODA: ACARI : MESOSTIGMATA) A systematic survey of spinturnicid mites (Mesostigmata:Spinturnicidae) was performed with specimens collected on bats from 19 localities in Brazil. New host records and new geographical records for the family Spinturnicidae are reported. Observations are made on the variations of meristic and qualitative taxonomic characters in some of the 9 species of the genus Periglischrus and 2 species of Spinturnix. A discussion of the host records regarded as exceptions to the level of host-specificity currently admitted for this family of parasites was founded on bionomical data of the bats. The intraspecific variation of the quantitative taxonomic characters most commonly used in the classification of the genus Periglischrus was analyzed 45 by means of statistical tests of significance. This procedure was applied in 2 samples of males of P. iheringi collected on 2 different host genera from the same locality. Two samples of males and 3 samples of females of P. ojastii collected on bats of the same species, trapped in different localities, had also their quantitative variations compared statistically
