Diagnosis. This species most closely resembles T. flavidorsalis by having a sulciform interior branch of the dorsal tibial apophysis in the male palp ( Figs 5C–E ) and reniform spermathecae in the epigyne ( Figs 5F, G ). T. decorata , however, can be distinguished from T. flavidoralis by the following characters: sulciform interior branch of the dorsal tibial apophysis narrow in T. decorata ( Figs 5C, E ), whereas finger-shaped in T. flavidorsalis ; embolus slightly bifurcated distally in T. decorata , whereas not bifurcated in T. flavidorsalis ; tegular apophysis longer than wide and with blunt end in prolateral view in T. decorata , whereas, wider than long and with a sharp end in T. flavidorsalis ; anterior margin of the median lobe of the epigyne rounded in T. decorata ( Fig. 5F ), whereas an inverted, triangular-shape in T. flavidorsalis .

Description. See Zhang et al. (2008). Habitus, male palp and epigyne ( Fig. 5 ).

Distribution. China (Fujian, Guangxi, Hunan, Zhejiang) ( Fig. 24 ).
