Chen leg., deposited in IZCAS . Paratypes . 4 females , same data as holotype, deposited in IZCAS . Etymology. The specific name is a patronym in honor of Prof. San'an Wu from Beijing Forestry University; noun in apposition. Prof. Wu is a leading taxonomist in Coccoidea in China . Diagnosis. Males of this new species are similar to C. medina (Paquin & Dupérré, 2009: 31, figs 56–57), but can be distinguished by the smooth distal part of tegulum (with deep notch in C. medina ), RTA without setae (with 5 setae in C. medina ). Females of this new species are similar to C. avicularia Li , sp. nov. ( Figs 64 , 66A–B ), but can be distinguished by the relatively small and undivided BO (large and divided BO in C. avicularia Li , sp. nov. ), the reniform spermathecae (spherical in C. avicularia Li , sp. nov. ), and the end of copulatory duct not extending laterally (laterally extending in C. avicularia Li , sp. nov. ).
