Pseudoscorpions are one of the most diverse of the smaller arachnid orders but there is relatively little information about the distribution of these tiny animals, especially in Neotropical caves. Here we map the distribution of the Pseudoscorpiones in Brazilian caves with record of 12 families and 22 genera, total 313 caves from 13 states. Among them, two families (Atemnidae and Geogarypidae) with three genera (Brazilatemnus Muchmore, 1975, Paratemnoides Harvey, 1991 and Geogarypus Chamberlin, 1930) are recorded for the first time in cave habitat as well as other seven genera previously unknown for Brazilian caves (Olpiolum Beier, 1931, Pachyolpium Beier 1931, Tyrannochthonius Chamberlin, 1929, Lagynochthonius Beier, 1951, Neocheiridium Beier 1932, Ideoblothrus Balzan, 1892 and Heterolophus Tömösváry, 1884) but these genera are from families already recorded in this habitat, and have their distributional ranges expanded for all other previously recorded genera. We present these data in maps, considering the biogeographical provinces. For the genus Spelaeochernes Mahnert, 2001, we re-evaluate its Schiner-Racovitza status and propose the troglobite status. Finally, we discuss the ranges of the pseudoscorpion families/genera for Brazilian caves (Suppl. material 1).
