Diagnosis. The male of Z. xiaoi Yin, Bao and Zhang, 1999 is very similar to that of Z. exiguoides Platnick and Shadab, 1983 in the embolus and median apophysis, tegulum and subtegulum, and retrolateral tibial apophysis, but clearly distinguished from the latter by the shape of the median apophysis tip and the retrolateral tibial apophysis ( Fig. 8 B-G). The female of Z. xiaoi is also very similar to that of Z. exiguoides in the anterior and lateral margins on the epigynal plate, and the internal genitalia, but different from the latter by the broader epigynum, the size of spermathecae and fertilization ducts, and the curvature of genital ducts ( Fig. 7 A-C, E-F).
