Diagnosis.
Females of Phrynarachne yunhui sp. nov. are similar to P. mammillata in having the anterior edge and posterior edges of the median plate procurved and the posterior edge with a depression, and in having kidney-shaped spermathecae. However, Phrynarachne yunhui sp. nov. can be distinguished by the oval median plate (vs M-shaped in P. mammillata ) and the broad anterior edge of the spermathecae (vs narrow in P. mammillata ).
