Pararoncus histrionicus Chamberlin, 1938, by original designation. Diagnosis. Pararoncus can be distinguished from other syarinid genera by the following characters: epistome present (Figs 2A , 4B , 6B ); movable chelal finger with an accessory tooth (or tooth-like sensorium Fig. 2E ); trichobothrium ib on the paraxial side of chela and closer to esb ; ist median and between est and isb (Figs 2D , 4C , 6E ); and coxa I with an apical process (Figs 2B, C , 4A , 6A ) ( Chamberlin 1938 ; Curcic 1979). Figure 1. Type localities of all Pararoncus species according to the World Pseudoscorpiones Catalog (2023). The two new species are represented by squares, circles indicate epigean species in Japan, and triangles indicate troglobitic species. Figure 2. Genus characters of Pararoncus . A. Epistome; B.
