WITHIIDAE Chamberlin, 1931 Thirty-seven genera have been described in this family, but five species of pseudoscorpionids belonging to four genera were found on ten Passalidae species from two genera (Aguiar and Bürnheim 1998; Poinar et al. 1998; Martinez et al. 2020). Two species were collected from Passalus interruptus, P. interstitialis, P. punctiger and P. rhodantropoides and the largest number of hosts was found for Vuctorwithius gracilimanus (Mahnert, 1979) (6) and Cacodemonius sp. (5) (Tables 2, 4, 14). Together, on the same host species, Pseudoscorpiones were found with Mesostigmata eight times; Astigmata (1); Trombidiformes (1); Mesostigmata and Trombidiformes (3); Astigmata and Mesostigmata (1); Mesostigmata and Oribatida (1); Mesostigmata, Oribatida and Trombidiformes (2); Astigmata, Mesostigmata and Oribatida (1); and Astigmata, Mesostigmata and Trombidiformes (1).
