The new species seems to be rare, considering that only 1-3 specimens were collected at each site, in 10 quantitative samples (sample size of 0.05 m2). As distinct from other pseudoscorpion species, all specimens of
sp. nov. were collected only from quantitative samples and no specimens were collected by other techniques (sifting, pitfall trapping, and/or rearing from substrata in the lab).
