Diagnosis.

Males of Phrynarachne huangshanensis can be distinguished from those of P. mammillata by the ratio of the length of the embolus to the length of the embolus base (7:1 in P. huangshanensis vs 10:1 in P. mammillata), and the ratio of the length of the RTA to the length of the VTA (3:1 in P. huangshanensis vs 2:1 in P. mammillata). Females can be differentiated by the length to width ratio of the median plate (3:1 in P. huangshanensis vs 5:1 in P. mammillata), and the V-shaped median plate (vs M-shaped in P. mammillata).
