). Although far from the river, the substrates were moist due to the high humidity in the chamber provided by dripping speleothems. Considering the huge dimensions of the cave, a thorough search was only performed in few areas, therefore the low number of registered specimens (less than 10 – some of them were not collected) does not necessarily indicate that the species present low population density. Gruta do Padre cave also presents other described troglobitic species, such as the beetle
