Type material: Holotype ♂, JAPAN: Hiroshima prefecture, Mt. Azuma, 35°00′N 133°00′E, 621 m, 15.VIII.1963, Y. Morinaga; 1 ♀ paratype, Tottori prefecture, Mt. Daisen , 35°12′N 133°21′E, 366 m, VII.1937, M. Tanaka; depos- ited in CASJ, examined.

Material examined. CHINA: Anhui: 14 ♀, Yuexi County, Yaoluoping Nature Reserve , 30°59.007′N 116°04.901′E, 1005 m, 31.V.2018, L.Y. Wang ( SWUC) ; 15 ♀, Yaoluoping Nature Reserve , 21–22.VII.2007, Z.S. Zhang ( SWUC) .

Diagnosis. This species resembles T. concava by having a sulciform interior branch of the dorsal tibial apophysis in the male palp (figs 9–11 in Zhang et al. 2008) and by having similar reniform spermathecae in the female epigyne ( Figs 6B–E ). T. flavidoralis , however, can be distinguished from T. concava by the following: tegular apophysis rectangular with a sharp end in prolateral view in T. flavidoralis , whereas tongue-shaped with blunt end in T. concava ; anterior margin of the epigynal median lobe inverted triangular-shaped in T. flavidoralis ( Figs 6B, D ), whereas rounded in T. decorata .

Description. See Zhang et al. (2008). Female habitus and epigyne ( Fig. 6 ).

Distribution. Japan (Hiroshima, Tottori) and China (Anhui) ( Fig. 24 ).
