Diagnosis.

Males of P. zhaoi can be distinguished from those of all other Portia species by having the longest embolus (Fig. 6A ); in addition, from those of P. erlangping sp. nov., P. fimbriata and P. xishan sp. nov. By the finger-shaped retrolateral tibial apophysis (Fig. 6A, B, D ; see 7G in Wanless (1978)); from those of P. quei by the thicker ventral tibial apophysis (Fig. 6B ; see fig. 661 in Peng et al. (1993)). Females of P. zhaoi can be distinguished from those of P. labiata by its longer copulatory ducts (Fig. 6E, F ; see fig. 1D in Zhu et al. (2007)); from those of P. bawang sp. nov., P. fajing sp. nov., P. fimbriata , P. quei , P. taiwanica , and P. xishan sp. nov. by the circular epigyne orifice (Fig. 6E ; see fig. 8C-E in Wanless (1978), fig. 664 and 666 in Peng et al. (1993), and fig. 4F in Zhang and Li (2005), respecitively).
