Diagnosis.

Zoica oculata can be distinguished from all other congeners by the large body (2.77–4.26), long and hook-shaped terminal apophysis, the narrow and long conductor, the long twining stalk of spermathecae (Figs 8 View Figure 8 , 9 C – H View Figure 9 ), and the block-shaped markings in opisthosoma (Fig. 1 E, F View Figure 1 , Buchar 1997: fig. 1).
