C470D314FFE51726FF59FE8749DEFDEA.taxon	diagnosis	Diagnosis. This genus is most similar to Neobisium Chamberlin, 1930 but can be distinguished by the position of the trichobothrium ist on the fixed chelal finger. In Parobisium, ist is positioned subdistally and closer to est whereas in Neobisium, ist is positioned sub-basally and closer to ib (Chamberlin, 1930; Zhang et al. 2020).	en	Jeong, Kyung-Hoon, Choi, Yong-Gun, Harms, Danilo, Yoo, Jung-Sun, Kim, Sora (2026): Two new species of Parobisium (Pseudoscorpiones: Neobisiidae) Chamberlin, 1930 from South Korea, with a preliminary phylogeny of the genus.
