sp. nov. was generally found in large cavities with horizontal projections varying from 9.5 to 216 meters (
<emphasis italics="true" pageId="0" pageNumber="143">N</emphasis>
= 13, mean = 107 m). All caves where the species was found have only one entrance and are located only in the middle and high slopes of Serra Norte. Most caves have aphotic zones or twilight zones (except for cavities N1_0103 and N1_0084) and high humidity, thus explaining the observed presence of small bodies of water in almost all cavities, especially during the wet season. The number of troglobitic species in these caves varied from one to ten (average 5.3 per cave), with species of the following taxa: spiders -
