REMARKS
This species is similar to Paracaphyllisa adinandrae Kuang & Luo, 2004, but can be differentiated by the prodorsal shield with median line incomplete, sides with granules; dorsal opisthosoma ridges with filamentous microtubercles; coxal area smooth, tarsal solenidion knobbed, coverflap with basal granules and distal longitudinal lines; setae h1 present (P. adinandrae prodorsal shield median line complete and sides smooth; dorsal opisthosoma ridges smooth, without filament microtubercles; coxal area with short lines; tarsal solenidion slightly knobbed coverflap smooth; setae h1 absent in P. adinandrae; see Kuang et al. 2004).
