Sesieutes zhui Zhang and Fu, 2011 : 71 , figs 1–15, description of ♂♀. Diagnosis Females of J. zhui comb. nov. can be distinguished from those of J. schwendingeri comb. nov. by their smaller copulatory orifices that are located more anteriorly, internal ducts that are simple, and the spermathecae that are robust. In J. schwendingeri comb. nov. the copulatory orifices are distinctly larger and medially situated on the epigynal plate ( Figure 7 A ), the internal ducts are partially enlarged, and the anterior portion of the spermathecae is spherical ( Figure 8 F ). Males differ by the apex of the conductor, which is blunt, whereas in J. schwendingeri comb. nov. the conductor is sharply pointed and more elongate ( Figures 4 A , 9 A ). Distribution Yunnan Province, southern China.
