Etymology: The epithet is a patronym in honor of Prof. Yan Heng-mei, who contributed much work to the taxonomy of Chinese spiders; noun. Diagnosis: This new species can be distinguished from all other congeners by: the entrance grooves with four and half coils before entering the spermathecae ( Fig. 280C, D ), spermathecae elliptical ( Fig. 280C, D ).
